What to Expect at a Home Inspection: A Buyer's Guide

This article is general information, not professional advice. Home inspection standards and inspector regulation vary by province and change over time; confirm the specifics where you are buying.

Buying a home is the largest purchase most people ever make, and a home inspection is the step where you get an independent, professional look at what you are actually buying, before the deal becomes final. It is not a formality. A good inspection tells you what works, what is worn, what will need money soon, and occasionally what should make you walk away. Here is what to expect.

What a home inspection is

A home inspection is a visual, non-invasive assessment of a home's accessible systems and components, carried out by a home inspector, usually during the conditional period after your offer is accepted. The inspector spends a few hours going through the property and then gives you a written report on its condition.

The word to hold onto is visual. An inspector examines what can be seen and safely reached. They do not open up walls, lift flooring, or dismantle equipment. So an inspection is a thorough informed look, not an X-ray.

What it typically covers

A general home inspection usually looks at the major systems and structure, including:

Roof (from the ground or roof where accessible), flashing, gutters, and downspouts.
Exterior and envelope: cladding, trim, grading and drainage away from the house, walkways, and visible decks and porches.
Structure and foundation: visible framing, foundation walls, and signs of movement or water.
Attic, insulation, and ventilation.
Electrical: the panel, visible wiring, and a sampling of outlets, switches, and fixtures.
Plumbing: visible supply and drain lines, water heater, and fixtures.
Heating and cooling (HVAC): the furnace or boiler, and air conditioning where present and weather permits.
Interior: walls, ceilings, floors, windows, doors, stairs, and railings.

The report describes the condition of each, flags deficiencies, and often distinguishes between things that need attention now and things to simply keep an eye on.

What it deliberately does not cover

Knowing the limits keeps your expectations right and can save you from a false sense of security:

It is not invasive. Anything hidden behind finished walls, under floors, or buried underground is outside its scope.
It usually excludes specialized testing unless you arrange it separately: things like mould, radon, asbestos, or air quality.
It is generally not a code-compliance inspection and not an appraisal of the home's market value.
Pools, septic systems, and wells are often excluded or handled by a separate specialist.
It is not a warranty or a guarantee that nothing will fail after you move in. It reports condition on the day, not the future.

If the inspection raises a concern in a specialized area, the right next step is often a specialist (a roofer, an HVAC technician, a structural engineer), not a bigger general inspection.

How it differs from a new-build PDI

If you are buying a brand-new home, the equivalent step is different. A Pre-Delivery Inspection (PDI) is a builder-led walkthrough that creates the official record of a new home's condition at possession and ties into the builder's new-home warranty. A home inspection, by contrast, is something you arrange independently, most often when buying a resale home, and it is not tied to any warranty. If your purchase is a new build, see our guide to what to expect at your PDI.

Should you make your offer conditional on it?

In most purchases, yes, a condition on a satisfactory home inspection is standard and prudent. It gives you a window to inspect and, depending on what turns up, to renegotiate the price, ask for repairs, or withdraw. In very competitive markets, some buyers waive the inspection condition to make their offer more attractive; understand that this trades away your safety net, and weigh that risk seriously against the home's age and condition.

How to choose an inspector

Check regulation where you buy. Some provinces license or regulate home inspectors and others do not, and this changes over time, so verify the current situation locally.
Look for recognized credentials and membership in a reputable professional association.
Confirm they carry errors-and-omissions insurance.
Ask to see a sample report so you know what you will actually receive.
Attend the inspection if you can. Walking the home with the inspector is the single best way to understand the report, because they can show you what they mean and point out routine maintenance you will want to know as an owner.

How to read and use the report

A good report is not a pass or fail. It is a condition summary, usually with photos. Read it for three things:

Safety and structural issues first, these carry the most weight.
Big-ticket systems near the end of their life (roof, furnace, water heater), so you can budget or negotiate.
Maintenance items you will simply want to handle as the new owner.

Then decide: proceed, renegotiate, bring in a specialist, or walk away. Keep the report with your records either way, it becomes a useful baseline and maintenance to-do list once the home is yours.

Frequently asked questions

Is a home inspection mandatory? No, it is not legally required, but it is strongly advisable. Most buyers make their offer conditional on a satisfactory inspection so they can inspect before the purchase is firm.

What does a home inspection not cover? It is visual and non-invasive, so hidden or buried components are out of scope, and it typically excludes specialized testing (mould, radon, asbestos), code compliance, appraisal, and often pools, septic, and wells.

Home inspection or PDI, which do I need? A PDI is for a brand-new build with the builder and ties into the new-home warranty. A home inspection is an independent assessment you arrange, usually for a resale home. Which you need depends on whether the home is new or resale.

Should I attend the inspection? If you can, yes. Being there turns the written report into a guided tour of your future home and its maintenance needs.
