Free NHIE Practice Test: 60 Questions With Explanations

Correct answer: C. Report the aluminum wiring and twist-on pigtails; refer to a qualified electrician for a recognized permanent repair.

The CPSC found that standard twist-on connectors used to pigtail aluminum branch wiring overheated in its testing and don't solve the problem. It describes copper rewiring and COPALUM repairs, with AlumiConn as the next-best permanent alternative when COPALUM is unavailable. Your job here is to report what you saw and send it to a qualified electrician; the observations don't justify choosing a repair for the client or condemning the house.

Why the other choices are weaker

• A. Twist-on pigtails are exactly the method CPSC says is not a permanent fix.
• B. Antioxidant alone isn't one of CPSC's recognized permanent repairs, and this is not a do-it-yourself connection repair.
• D. This overstates the finding. CPSC describes repair options short of full rewiring; these observations alone don't establish an occupancy ruling.

Item ID: NHIE-D1T5-01

Correct answer: C. Report it as a safety defect: the gate should open outward, self-close, and self-latch.

CPSC's barrier guidelines call for pedestrian gates that open out from the pool and are self-closing and self-latching, so a child pushing on the gate can't get in. A gate that stays open defeats the barrier, which makes this a safety finding rather than a convenience note.

Why the other choices are weaker

• A. "Opens and closes" isn't the standard. The barrier only works if the gate closes and latches by itself.
• B. Behavior advice doesn't correct the defect, and the hazard exists whether or not anyone remembers to lock it.
• D. The question expressly includes the access barrier in the agreed inspection. A pool exclusion in some basic standards doesn't erase that agreed scope.

Item ID: NHIE-D1T1-01

Correct answer: A. Report a safety defect: contact reversal isn't working; refer to a garage door technician.

The door has failed its specified contact-reversal test. Working photo-eyes don't excuse a failed contact reversal. Federal entrapment-protection rules include prescribed laboratory obstruction tests, but those test dimensions and timings are not a universal home-inspection procedure. Report the failed safety function and refer it to a garage door technician.

Why the other choices are weaker

• B. The photo-eyes and contact-reversal function address different obstruction situations. Passing one test doesn't erase failure of the other.
• C. Ten seconds is not a substitute for the manufacturer's specified test. The observed door kept pushing instead of reversing.
• D. Disabling a safety device adds risk and is not a remedy for a failed reversal test.

Item ID: NHIE-D1T2-01

Correct answer: C. Warn the occupants without entering the danger area, move away, and call the gas utility's emergency line from a safe location.

A suspected gas leak needs action now, not only a written report later. The gas utility's safety instructions say to leave the affected area, avoid switches, doorbells and other ignition sources, and call from a safe location. Warn others without entering the danger area; do not operate appliances or try to repair the leak.

Why the other choices are weaker

• A. A report written hours later doesn't protect the people inside right now.
• B. Do not attempt a repair during a suspected gas leak; leave and get emergency responders involved.
• D. Operating gas equipment during a suspected leak adds risk and doesn't change what you need to do.

Item ID: NHIE-D2T4-01

Correct answer: D. Refrigerant absorbs indoor heat, moisture condenses on the cold indoor coil, and the outdoor coil releases heat outside.

An air conditioner doesn't make "cold." It moves heat. Refrigerant absorbs heat at the indoor coil and releases it outdoors. Moisture can condense on the cold indoor coil and drain away; the water does not become part of the refrigerant circuit.

Why the other choices are weaker

• A. Refrigerant stays sealed inside the system. Air passes over the coil; refrigerant isn't added to the air.
• B. The outdoor condensing unit rejects heat; it doesn't supply cooled outdoor air through the house's ducts.
• C. A filter traps particles. It doesn't remove heat, and a clogged one actually reduces cooling.

Item ID: NHIE-D1T6-01

Correct answer: C. To direct roof runoff away from the wall, usually into the gutter.

PNNL's Building America guide describes kick-out flashing as a piece at the bottom of a roof section beside a wall that directs runoff away from the wall and usually into a gutter. Without it, water running down the step flashing can be driven into or behind the siding. The stained, soft siding is consistent with that, so you'd report both and recommend a roofer or siding contractor.

Why the other choices are weaker

• A. Kick-out flashing is a water-control part, not a ventilation part.
• B. Gutters are supported by hangers or brackets. Flashing diverts water.
• D. Flashing works with the weather-resistant barrier; it doesn't replace it.

Sources: PNNL, Flashing at Roof-Wall Intersections in Existing Homes (Scope; Description; Ensuring Success); EBPHI content outline — topic coverage (Domain 1, Task 3, C (roof flashings); coverage, not a technical-answer source)

Item ID: NHIE-D1T3-01

Correct answer: C. It sets the scope, limitations, and terms before work begins.

EBPHI's outline describes the written pre-inspection agreement as establishing the rights and responsibilities of the inspector and client, including scope, limitations, and terms of service. Its value is that expectations are settled before the inspection, not argued about afterward.

Why the other choices are weaker

• A. No visual inspection can promise that. Agreements typically state limitations, not guarantees.
• B. An inspection agreement is between the inspector and the client; it doesn't assign duties to an agent.
• D. Its main job is to set expectations up front, and the outline treats it as a core professional responsibility.

Sources: EBPHI exam overview packet and content outline (Domain 3, Task 1: agreement scope, parties and timing)

Item ID: NHIE-D3T1-01

Correct answer: B. Report a structural concern consistent with lateral pressure; refer to a structural engineer.

HUD's inspection guide describes horizontal cracking and inward bowing of masonry foundation walls under lateral loading. Here, the visible displacement makes this a structural concern, not a routine cosmetic crack. Describe the location, cracking and movement, then refer for structural evaluation rather than claiming that the exact cause or repair is already known.

Why the other choices are weaker

• A. Shrinkage cracks don't usually come with a wall pushed out of plane. The displacement is the key fact.
• C. Cosmetic sealing doesn't address movement and could hide its progress.
• D. The facts don't establish a repair design or price. A cost estimate cannot replace evaluation of the displaced wall.

Sources: HUD, Residential Rehabilitation Inspection Guide, part 2 (§4.4, printed pp. 47–48 / PDF pp. 38–39: horizontal bowing of masonry foundation walls); EBPHI content outline — topic coverage (Domain 1, Task 4, A.4 and A.6 (typical defects; applied forces incl. hydrostatic pressure); coverage, not a technical-answer source)

Item ID: NHIE-D1T4-01

Correct answer: D. A serious safety defect: the relief path is blocked; recommend immediate plumber repair.

A T&P relief valve provides automatic temperature and pressure protection for a water heater. Capping its discharge defeats that protection. Watts' safety instructions prohibit restrictions in that discharge path. Report the blocked relief path immediately and recommend qualified plumber correction before further water-heater operation.

Why the other choices are weaker

• A. Stopping the drip by blocking the relief path removes the safety protection. A dripping valve needs evaluation, not a plug.
• B. A blocked relief path can be dangerous. Do not direct a homeowner to uncap or test a potentially hot, pressurized system; it needs qualified service.
• C. This is a safety defect, not routine maintenance.

Sources: Watts TAG-100, T&P relief-valve safety instructions (Single-page safety tag: relief discharge must not be restricted; installation and service warnings); ASHI Standard of Practice (§13.2.C–F: unsafe procedures and inoperable/safety controls); EBPHI content outline — topic coverage (Domain 1, Task 10, D.7–D.8 (T&P relief defects; lack of relief valve); coverage, not a technical-answer source)

Item ID: NHIE-D1T10-01

Correct answer: A. Report the exposed combustible facing as a defect needing correction.

Ordinary kraft paper facing is combustible and should not be left exposed. Knauf's guidance distinguishes it from facing specifically rated for exposed use. The finding is about exposure, not the insulation's R-value.

Why the other choices are weaker

• B. R-value doesn't address the fire concern from an exposed combustible facing.
• C. The manufacturer identifies a fire concern from ordinary exposed kraft facing, not just an unfinished appearance.
• D. Overreach. The issue is exposed facing, not the presence of insulation.

Sources: Knauf, Faced vs. Unfaced Insulation (Facing/fire-safety discussion); EBPHI content outline — topic coverage (Domain 1, Task 8, A.5–A.6 (exposed paper backing; fire hazards); coverage, not a technical-answer source)

Item ID: NHIE-D1T8-01

Correct answer: D. State that the attic wasn't inspected, why, and recommend inspecting it once accessible.

EBPHI's outline asks you to describe what was NOT inspected and why, including inaccessible areas. ASHI's Standard of Practice does not require moving personal belongings. A clear limitation tells the client exactly what remains unknown.

Why the other choices are weaker

• A. You can't report an area as satisfactory when you didn't inspect it.
• B. Silence hides a gap the client needs to know about.
• C. Blocked access isn't the same as no attic. That statement would be false.

Sources: ASHI Standard of Practice (§2.2.B.4; §13.2.F.3: inaccessible areas and moving personal property); EBPHI content outline — topic coverage (Domain 2, Task 2, items 1–2 (common limitations; limitations of a visual inspection); coverage, not a technical-answer source)

Item ID: NHIE-D2T2-01

Correct answer: C. Report the crushed plastic duct as a fire hazard; recommend metal duct.

CPSC recommends replacing plastic or foil accordion duct with rigid or corrugated semi-rigid metal duct. It explains that flexible plastic duct traps lint more easily and is more likely to kink or crush, cutting airflow. Blocked airflow can cause excessive heat and fires. EBPHI's outline lists plastic dryer ducts as a typical defect.

Why the other choices are weaker

• A. Cleaning helps, but the duct material and crushing are the defect.
• B. The dryer exhaust is included in this inspection; its material and condition are reportable.
• D. Exhaust should go outdoors. Venting into a garage moves lint and moisture indoors.

Sources: CPSC Pub. 5022, Overheated Clothes Dryers Can Cause Fires (Single-page duct material, lint and airflow guidance); ASHI Standard of Practice (§11.1: clothes dryer exhaust); EBPHI content outline — topic coverage (Domain 1, Task 9, A.5–A.6 (plastic dryer ducts; fire hazards); coverage, not a technical-answer source)

Item ID: NHIE-D1T9-01

Correct answer: B. Report missing alarms in the bedrooms, on the main floor, and in the basement.

The U.S. Fire Administration recommends smoke alarms inside and outside each bedroom and sleeping area, and on every level of the home. One hallway alarm leaves the bedrooms and two whole levels uncovered. EBPHI's outline includes smoke alarm placement under life safety.

Why the other choices are weaker

• A. Current guidance calls for alarms inside bedrooms and on every level, not just one hallway.
• C. A CO alarm doesn't replace a smoke alarm unless it's a listed combination unit.
• D. The kitchen is the wrong priority, and one more alarm still leaves the bedrooms and levels uncovered.

Item ID: NHIE-D1T13-01

Correct answer: D. Heat pulled from the outdoor air and moved indoors by the refrigerant cycle.

ENERGY STAR explains that a heat pump runs the air-conditioning cycle in reverse in winter, extracting heat energy from outside and transferring it into the home. With backup heat off, the refrigerant cycle is doing the work.

Why the other choices are weaker

• A. This electric heat pump moves heat through a refrigerant cycle; it is not obtaining heat by burning gas in the outdoor unit.
• B. The question says the supplemental heat is off.
• C. The blower moves air across the coil. It isn't the heat source.

Sources: ENERGY STAR, How Does a Heat Pump Work? (Heating/winter operation); EBPHI content outline — topic coverage (Domain 1, Task 6, A.3 (heat pumps); Task 7, A.3; coverage, not a technical-answer source)

Item ID: NHIE-D1T7-01

Correct answer: B. Report it as a safety concern; recommend a chimney professional's evaluation before use.

EPA's Burn Wise guidance (an archived program page) explains that chimney cracks can let smoke into the home or expose the chimney's components to high temperatures that may cause a fire. It recommends professional inspection. A crack reaching the flue isn't cosmetic.

Why the other choices are weaker

• A. A crack into the flue path is a venting and fire concern, not an appearance issue.
• C. Exterior caulk is not evidence of a suitable repair for a damaged flue. The chimney needs qualified evaluation before use.
• D. A stove that lights doesn't prove the venting is safe.

Sources: EPA Burn Wise, Wood-Burning Installation and Maintenance (Annual Inspections: chimney cracks, smoke entry and heat/fire concerns); EBPHI content outline — topic coverage (Domain 1, Task 12, A.8–A.9 (typical defects; safety issues); coverage, not a technical-answer source)

Item ID: NHIE-D1T12-01

Correct answer: A. Overhead service drop; main panel in the garage; main breaker labeled 200 amps; copper service-entrance conductors.

EBPHI's outline asks you to describe systems by their distinguishing characteristics, such as type, size, and location. This entry tells the client what's there and where, using what you observed, such as the breaker's label.

Why the other choices are weaker

• B. "Adequate" describes nothing. It gives no type, size, or location.
• C. That's an opinion with no description, and it implies a defect you haven't identified.
• D. Service size comes from labeling and equipment, not a guess from square footage.

Sources: EBPHI exam overview packet and content outline (Domain 2, Task 1: describe inspected systems by type, size and location)

Item ID: NHIE-D2T1-01

Correct answer: B. A trip hazard: riser heights vary by more than model code allows; recommend correction.

The 2021 IRC-based stair handout limits the difference between the largest and smallest riser in a flight to ⅜ inch. An 8-inch bottom riser beside 7-inch risers is a 1-inch difference—well beyond that limit. EBPHI lists improper riser height as a typical stair defect. Report the uneven risers as a trip concern and recommend correction.

Why the other choices are weaker

• A. A 1-inch difference is well past the ⅜-inch uniformity limit.
• C. A handrail helps but doesn't fix uneven risers.
• D. A trip hazard affects everyone, so report it either way.

Sources: MyBuildingPermit, Basic Stairs, Tip Sheet 01 (PDF p. 1, R311.7.5.1: maximum 3/8-inch riser variation); EBPHI content outline — topic coverage (Domain 1, Task 11, B.3 (improper riser height or tread depth); coverage, not a technical-answer source)

Item ID: NHIE-D1T11-01

Correct answer: B. Report the ledger attachment as improper; refer to a qualified contractor.

ICC's deck-safety guidance explains that nails subject to withdrawal must not be the sole ledger attachment. Its prescriptive examples use bolts or lag screws; an approved engineered connection is another possible route, but none is described here. Ledger failures can drop a deck suddenly, which is why EBPHI lists improper ledger attachment as a typical defect.

Why the other choices are weaker

• A. Corrosion resistance doesn't change the fact that nails alone aren't an acceptable ledger connection.
• C. More nails still leaves a nails-only connection subject to withdrawal. The appropriate connection must be evaluated, not guessed.
• D. Decks and their ledger attachment are listed in the NHIE outline.

Sources: ICC, Is Your Deck Safely Connected to Your House? (Ledger attachment discussion); EBPHI content outline — topic coverage (Domain 1, Task 2, C.3 (improper deck ledger attachment); coverage, not a technical-answer source)

Item ID: NHIE-D1T2-02

Correct answer: C. Decline, because payment tied to the sale closing is a conflict of interest.

ASHI's Code of Ethics bars inspectors from working under arrangements where their pay or future referrals depend on the reported findings or on the sale closing. Even if you'd report honestly, the arrangement gives you a reason not to.

Why the other choices are weaker

• A. Disclosure doesn't cure a fee that depends on the result.
• B. That makes the conflict worse by giving an interested party influence over the findings.
• D. A contract term doesn't override an ethics rule against contingent compensation.

Sources: ASHI Code of Ethics (§1.B: no compensation or referrals contingent on findings or sale closing); EBPHI content outline — topic coverage (Domain 3, Task 2, item 2 (conflicts of interest); coverage, not a technical-answer source)

Item ID: NHIE-D3T2-01

Correct answer: D. A double-tapped breaker; recommend correction by a licensed electrician.

The manufacturer permits one conductor at this terminal, but two are installed. That is the defect. Some terminals are identified for more than one conductor, so the mere presence of two wires is not enough without checking the terminal's identification. Report this connection for electrician correction.

Why the other choices are weaker

• A. Working circuits don't make the connection safe.
• B. Panel work belongs to an electrician, not the client.
• C. Overfusing means a breaker or fuse too large for the wire. This is a different defect.

Sources: OSHA, Electrical General Requirements (1910.303(c)(2)(ii), terminals for more than one conductor must be identified); EBPHI content outline — topic coverage (Domain 1, Task 5, B.9 (double-tapping, overfusing, loose connections); coverage, not a technical-answer source)

Item ID: NHIE-D1T5-02

Correct answer: D. Surface runoff is being directed toward the foundation.

The slope and the ponding show a surface-drainage problem. PNNL's guide calls preventing water from saturating the soil around the foundation the best defense against foundation water intrusion, which is why grade should carry runoff away. That observation shows a moisture risk. It doesn't prove any hidden component has failed.

Why the other choices are weaker

• A. You didn't observe the groundwater level. This assumes a hidden condition.
• B. Nothing in the observations shows the condition of a buried drain.
• C. The membrane is concealed. This is a diagnosis the facts don't support.

Sources: PNNL, Final Grade Slopes Away from Foundation (Scope and Description); EBPHI content outline — topic coverage (Domain 1, Task 1, A.3 (negative grade, poor drainage); coverage, not a technical-answer source)

Item ID: NHIE-D1T1-02

Correct answer: A. Report its age and condition; suggest budgeting for replacement without predicting failure.

EBPHI's outline expects you to know the expected service life of components. ASHI's Standard of Practice does not require a remaining-life prediction. The useful answer gives the client the facts (age, current condition) and context, without a forecast you can't support.

Why the other choices are weaker

• B. Age alone isn't a defect. It's working with no observed problems.
• C. A specific remaining-life prediction isn't supported by a visual inspection.
• D. Age is useful planning information the client would want.

Sources: ASHI Standard of Practice (§2.2.B.1 and §13.2.A.2: condition/service life and no required remaining-life prediction); EBPHI content outline — topic coverage (Domain 2, Task 3, item 1 (expected service life); coverage, not a technical-answer source)

Item ID: NHIE-D2T3-01

Correct answer: D. Each upper layer overlaps the layer below it, like shingles.

PNNL describes the principle as shingle-style lapping: the top layer of the weather-resistive barrier or flashing laps over the bottom layer so water can't drain behind the bottom layer. Gravity carries water down and out.

Why the other choices are weaker

• A. A reverse lap catches water and directs it behind the lower layer.
• B. Caulk alone ages and fails; the lap is what makes the detail drain.
• C. Thickness doesn't fix direction. Water follows the laps.

Sources: PNNL, Flashing at Roof-Wall Intersections in Existing Homes (Ensuring Success: shingle-style lapping); EBPHI content outline — topic coverage (Domain 1, Task 3, C.2 (flashing installation methods); coverage, not a technical-answer source)

Item ID: NHIE-D1T3-02

Correct answer: B. Backsiphonage could pull the solution into the potable water piping.

EPA's cross-connection manual describes backsiphonage as atmospheric pressure forcing a pollutant liquid toward a potable supply that is under a vacuum. A submerged hose end plus a pressure drop is the classic setup. That's why EBPHI lists cross-connection as a typical water-supply defect.

Why the other choices are weaker

• A. Flow can reverse when supply pressure drops. That's exactly what backsiphonage is.
• C. Thermal expansion is a different issue and doesn't involve the hose.
• D. A screen filters debris; it isn't a backflow preventer.

Sources: EPA, Cross-Connection Control Manual (Chapter 3, printed pp. 12–15 / PDF pp. 18–21; submerged-hose examples in appendix); EBPHI content outline — topic coverage (Domain 1, Task 10, A.4 (cross-connection); coverage, not a technical-answer source)

Item ID: NHIE-D1T10-02

Correct answer: A. An improper notch in the middle third of the span; refer for evaluation and repair.

Under the 2021 IRC rule summarized by ICC, notches in sawn joists are generally limited to one-sixth of the member's depth and are not allowed in the middle third of the span. End notches have a separate one-fourth-depth limit. Here, 9¼ ÷ 6 is about 1.54 inches, and the notch is about 2 inches deep at mid-span. It fails both the general depth limit and the location rule. EBPHI lists improper cuts and notches as typical floor-structure defects.

Why the other choices are weaker

• B. Depth isn't the only limit. The notch exceeds one-sixth of the stated depth (about 1.54 inches), and mid-span notches are not permitted.
• C. The middle-third prohibition applies to notches at either edge; being on the bottom does not make this cut acceptable.
• D. Wood filler is not a structural repair for a cut joist; the altered member needs qualified evaluation.

Sources: ICC CodeNotes, IRC Cutting, Drilling and Notching (PDF pp. 1–2, R502.8.1 and sawn-lumber table); EBPHI content outline — topic coverage (Domain 1, Task 4, B.4 (improper cuts and notches); coverage, not a technical-answer source)

Item ID: NHIE-D1T4-02

Correct answer: A. A fire-separation safety concern: provide self-closing or automatic-closing operation and self-latching.

The door between a garage and the living space is part of the separation that slows fire and car exhaust from reaching the house. The 2021 International Residential Code requires it to be self-closing (or automatic-closing) and self-latching. Older homes may have been built under earlier rules, so describe it as a safety concern and recommend correction.

Why the other choices are weaker

• B. Door construction matters, but a door left open doesn't separate anything.
• C. Relying on habit doesn't fix the missing closer.
• D. This is a fire-separation door, which EBPHI's outline covers under life safety.

Sources: MyBuildingPermit, Residential Garage Separation, Tip Sheet 06 (PDF p. 2, Doors, R302.5.1); EBPHI content outline — topic coverage (Domain 1, Task 13, item 2 (fire separation, fire-rated doors); coverage, not a technical-answer source)

Item ID: NHIE-D1T13-02

Correct answer: C. Get everyone outside to fresh air and call emergency services.

CPSC's guidance is direct: when a CO alarm sounds, immediately move outside to fresh air and call emergency services or 911, and don't try to locate the source yourself. Carbon monoxide is colorless and odorless, so you can't judge it by feel. Reporting comes later.

Why the other choices are weaker

• A. CPSC advises against hunting for the source. Get out first.
• B. Silencing a real alarm and staying inside ignores an emergency.
• D. One open window doesn't make the house safe. Leave and call for help.

Item ID: NHIE-D2T4-02

Correct answer: B. Evidence of a combustion problem; recommend qualified HVAC evaluation before further operation.

HUD's inspection guide identifies soot as evidence of poor combustion and calls for qualified attention to the burner and venting. The soot is observable; a specific failed heat-exchanger part is not. Report the condition and recommend qualified HVAC evaluation before further operation.

Why the other choices are weaker

• A. Heavy soot is not a basis for declaring normal, satisfactory combustion.
• C. That diagnosis goes beyond what you observed.
• D. Changing the thermostat setting does not evaluate or correct the combustion problem.

Sources: HUD, Residential Rehabilitation Inspection Guide, part 3 (PDF p. 25 / printed p. 86: soot, poor combustion and qualified furnace attention); EBPHI content outline — topic coverage (Domain 1, Task 7: heating-system combustion and safety; coverage only)

Item ID: NHIE-D1T7-02

Correct answer: B. Moist house air is leaking into the attic and condensing on cold sheathing.

PNNL explains that warm, moisture-laden house air leaking into a cold attic can cause condensation and frost on cold surfaces. The gaps you found are a plausible pathway, and the cold sheathing is where the moisture collects. Report both and recommend air-sealing evaluation; this pattern does not by itself rule out other moisture sources.

Why the other choices are weaker

• A. A roof leak is possible, but the cold sheathing and air gaps support condensation from indoor air as the best explanation given.
• C. Repeated condensation can wet and damage sheathing; it's a reportable moisture condition.
• D. Piling on batt or loose-fill insulation does not establish an air barrier and can create problems around heat-producing fixtures. The leakage paths need proper evaluation.

Item ID: NHIE-D1T8-02

Correct answer: D. Have the client receive and sign it before the inspection begins.

EBPHI's outline treats the timing of delivering and signing the agreement as a core professional responsibility. An agreement signed after the work can't set expectations for that work. Check your state's rules too.

Why the other choices are weaker

• A. The point of the agreement is to settle scope and limits before the work, not describe them afterward.
• B. An authorized representative can act for the client, but the question expressly says this agent has no signing authority.
• C. Payment isn't a substitute for an agreed scope and terms.

Sources: EBPHI exam overview packet and content outline (Domain 3, Task 1: client or authorized representative; agreement delivery/signing timing)

Item ID: NHIE-D3T1-02

Correct answer: A. The clogged filter is restricting airflow; recommend replacement and service.

The DOE notes that a clogged filter restricts airflow through the unit and reduces its ability to cool. That's what you can see. Concluding that the compressor or refrigerant charge has failed would go beyond your evidence.

Why the other choices are weaker

• B. Nothing observed shows compressor failure.
• C. Nothing in these observations establishes the refrigerant charge. That requires an appropriate service evaluation.
• D. A thermostat problem isn't indicated by weak airflow at the registers.

Item ID: NHIE-D1T6-02

Correct answer: B. Improper exhaust termination; recommend connecting it to the exterior.

PNNL's bathroom-exhaust guidance calls for ducting to the outdoors, not into an attic or other enclosed building space. A fan that dumps humid air into the attic just moves the moisture problem upstairs. Report the disconnected duct and recommend correction.

Why the other choices are weaker

• A. The fan's job is to get moist air out of the house, not into the attic.
• C. Attic ventilation isn't designed to handle bathroom moisture dumped into it.
• D. Report the defect now; waiting for damage helps no one.

Item ID: NHIE-D1T9-02

Correct answer: D. That the HVAC couldn't be fully operated; recommend confirming it once access is available.

EBPHI's outline specifically includes limitations caused by smart and emerging technology. When a device prevents normal operation, your report should say what you couldn't test and why, so the client can follow up.

Why the other choices are weaker

• A. You couldn't operate it. You can't report it as satisfactory.
• B. Being locked isn't the same as being broken.
• C. Smart-home limitations are named in the outline; the client needs to know what wasn't tested.

Sources: EBPHI exam overview packet and content outline (Domain 2, Task 2: limitations from smart and emerging technologies); ASHI Standard of Practice (§2.2.B.4: what was not inspected and why)

Item ID: NHIE-D2T2-02

Correct answer: C. A missing damper stop, a safety issue; refer to a qualified gas fireplace pro.

The G4 manual requires a fixed minimum permanent chimney opening and a fully open damper while the unit burns. The damper clamp prevents full closure. Here, neither a clamp nor another permanent stop is present, and the damper closes completely. Report the venting safety concern and recommend qualified correction before use.

Why the other choices are weaker

• A. With vented logs, the risk is someone lighting them with the damper closed.
• B. The manual permits alternatives when a clamp does not fit, but choosing or performing an alteration requires qualified installation judgment. Removal is not the only answer.
• D. The missing stop is the defect; you don't need to wait for evidence of spillage.

Item ID: NHIE-D1T12-02

Correct answer: D. GFCI: trips on current imbalance to cut shock risk. AFCI: detects arcing to cut fire risk.

OSHA explains that a GFCI interrupts power when the outgoing and returning current differ by about 5 milliamperes. CPSC explains that AFCIs address fire hazards from arcing, while GFCIs address shock hazards. Ordinary breakers may not respond to arcing until a fire has started.

Why the other choices are weaker

• A. They protect against different hazards: shock versus arcing fire.
• B. That's reversed.
• C. Arc-fault and overcurrent protection are different functions, even when one breaker provides both.

Item ID: NHIE-D1T5-03

Correct answer: C. Safety glazing is expected here and none was identified; refer to a glazing contractor.

The 2021 IRC-based glazing handout identifies this same-plane location within 24 inches of a door and below 60 inches as requiring safety glazing, subject to its listed exceptions. Safety glazing can have several kinds of permanent identification, and laminated glass has a certification alternative. With neither identification nor certification established here, report that safety glazing could not be verified and refer for confirmation or correction—not that an absent etched mark alone proves ordinary glass.

Why the other choices are weaker

• A. Double-pane doesn't mean safety glass.
• B. Testing by impact is unsafe and won't tell you the glass type.
• D. Condition isn't the issue; the glass type in this location is.

Item ID: NHIE-D1T2-03

Correct answer: D. It didn't operate using normal controls; refer to an appliance technician.

ASHI's Standard of Practice includes activating an installed dishwasher's primary function with normal controls. You observed a failure to operate. Naming a specific failed internal part would be a diagnosis you didn't make.

Why the other choices are weaker

• A. You didn't open or test the appliance, so you can't name the failed part.
• B. Appearance doesn't show function, and it didn't run.
• C. A non-operating appliance is a reportable finding.

Item ID: NHIE-D2T3-02

Correct answer: A. Reduced functional flow with galvanized piping; refer to a qualified plumber.

HUD's inspection guide explains that corrosion and mineral deposits can reduce flow through galvanized steel piping. Your job is to report the flow you observed and the piping type, and refer it, not to guess the inside condition.

Why the other choices are weaker

• B. A sharp drop is a functional-flow problem worth reporting.
• C. An undersized storage capacity would not explain this observed functional-flow drop; the evidence does not establish a water-heater defect.
• D. Possible, but you didn't measure it, and the galvanized pipe is an observed likely factor.

Item ID: NHIE-D1T10-03

Correct answer: A. An emergency escape hazard; recommend bars with an inside release.

The code-based emergency-escape handout requires bars over the required opening to be releasable or removable from inside without a key, tool or special knowledge. Fixed bars with no inside release block that escape route.

Why the other choices are weaker

• B. Security doesn't outweigh blocked emergency escape.
• C. The release must not depend on finding or using a key; the stated bars also have no inside release.
• D. Installed bars affect life safety, which is in scope.

Item ID: NHIE-D1T13-03

Correct answer: D. Report both and their likely connection; refer to a roofing contractor.

HUD's roof-inspection guidance calls for checking cracked or brittle flashing around roof penetrations and looking for associated interior water evidence. Linking the cracked boot to the stain below helps explain the concern, but it does not prove that the boot is the only source or that leakage is active now. Report both and refer for roofing evaluation.

Why the other choices are weaker

• A. The cracked boot is a plausible entry point and is itself a reportable defect.
• B. The stain is relevant evidence of past or present wetting, even if its timing is unknown.
• C. A guessed surface patch does not establish a suitable repair or evaluate the stained sheathing.

Item ID: NHIE-D1T3-03

Correct answer: A. Get the client's permission before releasing the report.

ASHI's Code of Ethics requires inspectors to protect client confidentiality, with a limited exception related to safety hazards. EBPHI's outline also lists report confidentiality under protecting the client's interest. Client confidentiality, not an assumption about copyright ownership, controls the disclosure in this scenario.

Why the other choices are weaker

• B. Reports aren't public documents.
• C. Being part of the transaction doesn't give the other side's agent a right to your client's report.
• D. Owning the property doesn't make the seller your client.

Item ID: NHIE-D3T2-02

Correct answer: B. Modified trusses; refer to a design professional such as a structural engineer.

Trusses are engineered systems: each web carries load as part of the whole. Removing webs can change how the roof carries load. The 2021 IRC-based framing checklist requires registered design-professional approval for truss alterations. Report the cut members and refer for that evaluation; a straight roof line is not approval of the alteration.

Why the other choices are weaker

• A. Damage can exist before sagging shows.
• C. Nailing pieces back in is not evidence of an approved engineered repair.
• D. It's a structural concern, not just an access issue.

Item ID: NHIE-D1T4-03

Correct answer: B. Check the area with a moisture meter and report what you confirm.

FLIR's technical guidance explains why a suspected moisture pattern needs confirmation. An infrared camera shows surface temperature differences, not water itself. A moisture meter helps confirm whether the cool spot is wet.

Why the other choices are weaker

• A. A temperature pattern alone does not confirm moisture or establish a roof leak.
• C. Infrared cameras don't detect mold.
• D. You saw something; follow up within your tools and report it.

Item ID: NHIE-D2T1-02

Correct answer: C. A missing or ineffective anti-tip bracket; recommend correction.

GE's guidance requires an anti-tip bracket and describes a visual check for this range configuration. A missing bracket leaves a tip-over hazard. Report the missing safety component and recommend installation according to the range's instructions; do not press on the open oven door to demonstrate tipping.

Why the other choices are weaker

• A. The manufacturer requires anti-tip protection; the range's weight is not a substitute.
• B. That's a workaround, not a fix.
• D. This is an installed cooking appliance included in the inspection, with a manufacturer-required safety component.

Item ID: NHIE-D1T11-02

Correct answer: B. Earth-to-wood contact; recommend restoring clearance and checking for damage.

HUD's wall-cladding guidance calls for checking wood near the ground for decay and maintaining separation from earth. Soil and mulch against wood can hold moisture and conceal damage. Report the contact, recommend restoring clearance, and have the affected siding checked rather than declaring a hidden insect infestation.

Why the other choices are weaker

• A. The type of mulch doesn't change wood-to-soil contact.
• C. Paint doesn't fix the contact or the moisture it holds.
• D. Report the condition that creates the risk; don't wait for damage.

Sources: HUD, Residential Rehabilitation Inspection Guide, part 2 (§2.1: wood cladding near the ground, decay and clearance); EBPHI content outline — topic coverage (Domain 1, Task 1, A.3 (earth-to-wood contact); coverage, not a technical-answer source)

Item ID: NHIE-D1T1-03

Correct answer: D. Name the brand, note it's a known problem panel type, and refer to an electrician.

EBPHI's outline lists Federal Pacific Stab-Lok among known problem electrical panels. In its historical investigation, CPSC reported failed calibration tests on certain breakers but closed the investigation without determining the safety of FPE breakers. A clean appearance does not establish trip performance. Name the panel and recommend electrician evaluation without claiming a recall, inevitable failure or an official finding that all such panels are safe.

Why the other choices are weaker

• A. No visible burning is not evidence that the breakers will trip correctly under fault conditions.
• B. That's a prediction you can't support from a visual inspection.
• C. Panel work belongs to an electrician, not the client.

Item ID: NHIE-D2T4-03

Correct answer: D. A combustion-gas safety hazard; inform the occupants and recommend HVAC correction before further operation.

HUD's inspection guide calls for sound, properly fitted vent connections; CPSC identifies fuel-burning heating and venting defects as carbon-monoxide concerns. A separated connector provides a path for combustion products to escape. Inform the occupants and recommend qualified correction before further operation. If a CO alarm sounds or an exposure is suspected, leave and call emergency services.

Why the other choices are weaker

• A. A disconnected vent is a safety hazard, not routine maintenance.
• B. Pushing the joint together does not establish a secure, properly supported or safe vent repair.
• C. An alarm helps, but it doesn't fix the open vent.

Sources: HUD, Residential Rehabilitation Inspection Guide, part 3 (PDF p. 25 / printed p. 86: vent connections); CPSC, Carbon Monoxide Fact Sheet (Heating-system and venting precautions; emergency response); EBPHI content outline — topic coverage (Domain 1, Task 7, C.5 (separated vent, back drafting); coverage, not a technical-answer source)

Item ID: NHIE-D1T7-03

Correct answer: C. No; this conditioned crawl space is designed without vents, so inspect it as designed.

PNNL describes unvented insulated crawlspaces with ground-moisture control, sealed boundaries and a conditioning or drying strategy. Adding outdoor vents simply because none are present could work against that design. Look for liner damage, moisture, and conditioning problems instead; the observations do not certify every part of the assembly.

Why the other choices are weaker

• A. An intentionally unvented crawlspace does not need outdoor vents merely because it is a crawlspace.
• B. A sealed ground liner is intended to control ground moisture. Its presence is not, by itself, a reason to add outdoor vents.
• D. Storage plans don't change how the space is designed to work.

Item ID: NHIE-D1T8-03

Correct answer: A. "Hall bath sink: trap leaking, cabinet floor swollen; ongoing leaks can cause decay and mold. Recommend a plumber."

A good defect entry says what, where, what you saw, why it matters, and who should handle it. EBPHI's outline lists common defects and the implications of not repairing them. EPA explains that moisture can support mold growth.

Why the other choices are weaker

• B. Too vague. It doesn't say where, what was seen, or who should fix it.
• C. It assumes a cause and recommends far more than the finding supports.
• D. It downplays visible water damage, and "monitor" isn't a real next step for an active leak.

Item ID: NHIE-D2T3-03

Correct answer: B. The wood isn't seasoned; wet wood makes more smoke and less heat.

EPA's Burn Wise guidance (an archived program page) says wood burns best below 20 percent moisture content, recommends seasoning for at least six months, and notes that wet wood causes excess smoke and wastes energy. Seasoning time alone does not guarantee that the wood is dry enough; a moisture reading checks the result. EBPHI's outline includes fuel types and combustion characteristics.

Why the other choices are weaker

• A. Painted, treated, or glued wood can release harmful chemicals and damage the appliance.
• C. Moisture, not oil content, is the issue here, and wet wood burns worse.
• D. It's one of the biggest factors in smoke and heat output.

Item ID: NHIE-D1T12-03

Correct answer: A. An overheating receptacle; stop using it until an electrician checks it.

CPSC advises that unusually warm or hot outlets should not be used until an electrician checks them, because an unsafe connection can start a fire. EBPHI lists overheating among common panel and wiring safety issues.

Why the other choices are weaker

• B. A receptacle shouldn't get hot under normal use.
• C. That leaves the faulty receptacle in place.
• D. A larger breaker doesn't fix a hot connection and can make overheating worse.

Item ID: NHIE-D1T5-04

Correct answer: B. Explain it's out of scope; amend the agreement in writing before inspecting it.

The pre-inspection agreement defines scope. EBPHI's outline frames the agreement around establishing the rights and responsibilities of both parties. Changing the scope on the fly without documenting it invites misunderstandings about what was inspected.

Why the other choices are weaker

• A. Undocumented scope changes blur what the client paid for and what you're responsible for.
• C. You can't vouch for something you didn't inspect.
• D. You can decline or amend the scope, but you should explain the situation.

Sources: EBPHI exam overview packet and content outline (Domain 3, Task 1: written agreement and scope of services)

Item ID: NHIE-D3T1-03

Correct answer: C. It didn't operate using normal controls; refer to an HVAC contractor.

The HRV did not respond to its normal control, so its intended operation and operating air balance were not demonstrated. ASHI's Standard of Practice does not require forcing an inoperative system to run. Report what you observed and refer it.

Why the other choices are weaker

• A. Windows don't replace a ventilation system that's supposed to work.
• B. Disconnecting an installed system is not an evaluation or repair of its failure to operate.
• D. A system that is not running cannot demonstrate its operating airflow balance.

Item ID: NHIE-D1T9-03

Correct answer: A. Inspect from safe vantage points and report the method and limitations.

ASHI's Standard of Practice requires describing the roof-inspection method and reporting relevant limitations, but does not require entering areas or performing procedures judged dangerous. HUD also cautions against walking brittle slate during an inspection. Safety comes first, and the report should be honest about how the roof was viewed.

Why the other choices are weaker

• B. The stated conditions are unsafe; there is no requirement to walk this roof despite that risk.
• C. You can still inspect from safe vantage points, and the client needs to know what you could and couldn't see.
• D. Interior conditions don't substitute for viewing the roof.

Sources: ASHI Standard of Practice (§5.1.B.2; §13.2.D/F: roof inspection method and unsafe access); HUD, Residential Rehabilitation Inspection Guide, part 2 (§2.5, printed p. 18 / PDF p. 9: brittle slate and safe observation); EBPHI content outline — topic coverage (Domain 2, Task 1, item 3 (common inspection methods); coverage, not a technical-answer source)

Item ID: NHIE-D1T3-04

Correct answer: C. Report both and their possible connection; refer to a plumber and check for damage.

HUD's bathroom-inspection guidance connects fixture-area leak checks with examining ceilings below. Here, the loose toilet and the stain below it may be related, but they do not prove the source or extent of leakage. Linking the observations helps the client understand why plumbing evaluation and a check for damage are needed.

Why the other choices are weaker

• A. A stain below a loose toilet isn't just cosmetic.
• B. The observations justify investigating the fixture above; they do not establish a roof leak or rule out other sources.
• D. Invasive investigation is outside a visual inspection.

Sources: HUD, Residential Rehabilitation Inspection Guide, part 2 (§3.3, printed p. 29 / PDF p. 20: bathroom leaks and ceiling below); EBPHI content outline — topic coverage (Domain 2, Task 4, item 2 (relationships between components); coverage, not a technical-answer source)

Item ID: NHIE-D2T4-04

Correct answer: D. A missing check valve causing drainback and short-cycling; refer to a plumber.

Without a functioning check valve, water in the vertical discharge pipe can fall back into the pit when the pump stops, so the pump re-pumps the same water. Zoeller's troubleshooting guidance links a missing or faulty check valve with frequent starts and stops. The observed drainback supports this finding rather than a guess about pump size.

Why the other choices are weaker

• A. Water rushing back and quick restarts aren't normal.
• B. The drainback, not pump size, explains what you observed.
• C. That could flood the basement during the next storm.

Item ID: NHIE-D1T10-04

Correct answer: A. Decline that work: ASHI restricts compensated repairs to covered systems within one year after inspection.

ASHI's Code of Ethics bars compensated repairs, replacements or upgrades to systems or components covered by its Standard of Practice for one year after inspection. The proposed paid roof repair next week falls within that restriction. It removes an incentive to create repair work for yourself.

Why the other choices are weaker

• B. A discount doesn't remove the conflict.
• C. Disclosure doesn't cure the conflict under ASHI's rule.
• D. ASHI's restriction runs for a year after the inspection, not just until closing.

Item ID: NHIE-D3T2-03

Correct answer: A. Painted sprinkler heads; refer to a fire-protection contractor.

Dyne's laboratory work shows that paint can interfere with sprinkler activation or spray distribution. That does not mean every painted head has necessarily failed, but painted heads need a qualified fire-protection contractor's evaluation. Report the visible condition without scraping, dismantling or trying to operate the heads.

Why the other choices are weaker

• B. Appearance doesn't matter; whether the head can work does.
• C. Tampering with sprinkler heads can damage them. That's a job for a qualified contractor.
• D. The question expressly includes this visual review in the agreement. It does not require a full functional test of the sprinkler system.

Item ID: NHIE-D1T13-04

Correct answer: B. "Gaps at the tub joint can let water into the wall, damaging materials and promoting mold. Correct the water entry and evaluate the softened wall."

The best entry connects the visible gap and soft drywall to a moisture concern and a useful next step. EPA advises correcting the water problem and drying or evaluating affected materials. Soft drywall does not prove hidden mold, and simply sealing over damage would leave its extent unresolved.

Why the other choices are weaker

• A. It treats the gap as routine upkeep and ignores the soft drywall and what could happen next.
• C. You didn't see inside the wall; that's an unsupported diagnosis.
• D. A repair prescription far beyond the finding, with no explanation.

Item ID: NHIE-D2T3-04

Correct answer: C. Describe both; refer the offset crack to a structural engineer.

Not every crack means the same thing. HUD's inspection guide distinguishes cracking and displacement patterns when evaluating foundation distress. A tight hairline crack and a crack with offset are different findings, so describe both and refer the displaced area for structural evaluation rather than calling both harmless or both failures.

Why the other choices are weaker

• A. The offset is a reason for further evaluation; these facts do not support dismissing it as harmless shrinkage.
• B. That overstates the hairline crack and can alarm the client unnecessarily.
• D. Cracks are a listed defect category; describe what you see.
