The NHICC National Home Inspector Examination is the centrally administered Canadian exam supporting the Registered Home Inspector (RHI) designation recognized by CAHPI. It contains about 175 questions, predominantly multiple-choice, plus a small manually graded photo defect-recognition and short report component, completed within a 3-hour maximum. The exam is delivered online and remote-invigilated with live video and audio monitoring. Content is built on a DACUM National Occupational Standard and is weighted roughly toward property and building inspection of systems and components (~63%), analysis of findings and reporting (~25%), and professional responsibilities including the Standards of Practice and code of ethics (~12%). NHICC maintains a database of over 1,300 questions. This free prep includes 100 research-based practice questions with detailed explanations and an AI tutor.

1A home inspector observes a stepped diagonal crack in a concrete block foundation wall that is wider at the top. This pattern most commonly indicates what condition?

A.Differential settlement of the foundation

B.Normal shrinkage during curing

C.Frost heave at a slab edge only

D.Carbonation of the mortar

Explanation: A stepped (stair-step) diagonal crack that widens toward the top of a block wall is a classic indicator of differential settlement, where one portion of the footing has dropped relative to another. Inspectors document the crack width, direction, and any displacement and recommend evaluation by a structural engineer when movement is significant.

2During a foundation inspection, horizontal cracking with inward bowing of a basement block wall most strongly suggests which cause?

A.Lateral soil or hydrostatic pressure against the wall

B.Roof truss uplift

C.Excessive interior humidity

D.Undersized floor joists

Explanation: Horizontal cracks accompanied by inward bowing of a foundation wall typically result from lateral pressure from saturated or expansive soil and hydrostatic water pressure. This is a structural concern, and the inspector should note the deflection and recommend evaluation by a qualified structural professional.

3Per Canadian home inspection standards of practice, an inspector's evaluation of the structure is best described as which type of inspection?

A.A destructive, code-compliance inspection

B.A warranty certification of the building

C.An engineering load calculation of all members

D.A visual inspection of readily accessible installed components

Explanation: Canadian standards of practice (such as CAHPI's National Standards) define the home inspection as a visual examination of readily accessible, installed systems and components. Inspectors are not required to move stored items, perform destructive testing, or calculate structural loads.

4What is the primary structural function of a footing beneath a foundation wall?

A.To provide a moisture break between soil and concrete

B.To anchor the wall against wind uplift

C.To distribute the building load over a wider area of soil

D.To act as a perimeter drainage channel

Explanation: A footing spreads the concentrated load of the foundation wall and the structure above over a larger soil bearing area, reducing the bearing pressure to within the soil's capacity. Inadequate footing size or bearing on poor soil leads to settlement.

5An inspector notes a wood support post bearing directly on a basement concrete floor slab with no visible pad footing. Why is this a concern?

A.The slab is too smooth to provide friction

B.A floor slab is generally not designed to carry concentrated point loads

C.Concrete floors trap radon under posts

D.Wood posts must always be steel in Canada

Explanation: A basement floor slab is typically a thin, non-structural slab-on-grade not designed to support the concentrated point load of a post. Posts should bear on a properly sized footing/pad below the slab; bearing directly on the slab can cause cracking and settlement.

6Cupping of floor joists or sagging visible from a crawl space, combined with a musty odour and high moisture readings, most likely points to which underlying problem?

A.Excessive attic insulation

B.Inadequate crawl space moisture control and ventilation

C.Oversized HVAC ductwork

D.Aluminum branch wiring

Explanation: Chronic moisture in a crawl space from poor ground-cover vapour barrier, drainage, or ventilation leads to elevated wood moisture, fungal decay, and joist distortion. The inspector should report the moisture source and the resulting structural and indoor-air-quality risks.

7In wood-frame construction, what is the main purpose of a header (lintel) above a window or door opening?

A.To provide a nailing surface for trim

B.To seal the opening against air leakage

C.To transfer loads from above around the opening to the supporting studs

D.To act as a fire stop in the wall cavity

Explanation: A header spans the opening and carries the loads from above (floor, roof, or wall) around the opening down to the jack/king studs at each side. An undersized or missing header causes sagging above the opening and sticking doors or windows.

8On a sloped asphalt-shingle roof, what is the primary purpose of step flashing where the roof meets a vertical sidewall?

A.To improve the roof's appearance

B.To hold the shingles down in high wind

C.To direct water away from the wall-roof intersection and onto the shingles

D.To provide attic ventilation

Explanation: Step flashing consists of individual bent metal pieces woven into each shingle course where a roof abuts a vertical wall, directing water back onto the roof surface and preventing leakage into the wall. Missing, reverse-lapped, or caulk-only 'flashing' is a common defect.

9Granule loss exposing the asphalt mat, along with curling and cracking of shingle tabs, is most indicative of what?

A.Recent hail impact only

B.Improper attic insulation R-value

C.Age-related wear and approaching end of service life

D.Defective drip edge

Explanation: Widespread granule loss, curling, and cracking are typical signs of asphalt shingles nearing the end of their service life from UV exposure and thermal cycling. The inspector reports the observed condition and notes that remaining life is limited, without predicting an exact date.

10What is the main function of an ice and water shield (self-adhering membrane) at eaves in a cold Canadian climate?

A.To increase shingle wind resistance

B.To improve shingle colour retention

C.To provide an additional vapour barrier for the attic

D.To protect the roof deck from leakage caused by ice damming

Explanation: A self-adhering bituminous membrane at the eaves seals around fasteners and protects the roof deck from water that backs up under shingles when ice dams form. It is a key cold-climate detail; its presence is generally not directly visible once shingles are installed, but its absence is a recognized leak risk.
