Pre-Purchase Inspection

Pre-Purchase Inspection

The pre-purchase inspection is a crucial step in the property acquisition process, even though it is not mandatory in Quebec. Conducted by a qualified building inspector who is a member of a recognized professional association, it costs between $500 and $1,000 depending on the size and type of property. The inspection covers major building components: structure and foundations, roofing, plumbing, electrical, heating, ventilation, insulation, windows and signs of water infiltration. Supplementary specialized inspections (pyrite, radon, vermiculite, mould, asbestos) may be recommended depending on the property's age and location, at a cost of $100 to $500 each. The Civil Code of Quebec provides a legal warranty against hidden defects (art. 1726 C.c.Q.), but proving the existence of a hidden defect after purchase is a lengthy, costly and uncertain process. The inspection allows you to identify problems upfront, negotiate a price reduction or repairs, or withdraw from the transaction if the inspection condition remains active in the purchase offer. Some lenders and CMHC may require a satisfactory inspection as a financing condition.

The Pre-Purchase Inspection in Quebec: An Essential Investment

For first-time buyers in Quebec, the pre-purchase inspection represents one of the wisest investments in the acquisition process. At a cost of $500 to $1,000, it can uncover problems that could cost tens of thousands of dollars in repairs. Although not mandatory in Quebec, forgoing the inspection, even in a bidding war, carries considerable risks that can turn the dream of homeownership into a financial nightmare.

What a Standard Inspection Covers

The pre-purchase inspection is performed by a qualified building inspector, ideally a member of a recognized professional association such as the Association des inspecteurs en batiments du Quebec (AIBQ) or the Association nationale des inspecteurs et experts en batiments (ANIEB). The examination typically lasts 2 to 4 hours depending on the property's size and produces a detailed report covering the building's main components.

  • Structure and foundations: cracks, settling, structural issues, presence of iron ochre in the French drain
  • Roofing: shingle or membrane condition, remaining lifespan, signs of leaks, flashing and gutter condition
  • Plumbing: pipe type (copper, PVC, cast iron, lead), water heater condition, water pressure, signs of leaks
  • Electrical: electrical panel (amperage capacity, breaker type), wiring compliance, electrical outlets
  • Heating and cooling: system type, equipment age and condition, energy efficiency
  • Ventilation and insulation: insulation quality, attic ventilation, heat recovery ventilator, signs of condensation
  • Windows and doors: weatherproofing, frame condition, double or triple glazing, signs of broken thermal seals
  • Exterior: siding, lot drainage, ground slope around foundations, balcony and deck condition

Supplementary Specialized Inspections

Depending on the property's age, type and location, specialized inspections may be recommended alongside the general inspection. Pyrite in backfill under concrete slabs (common in certain areas of Montreal's South Shore) can cause floor heaving and cost $50,000 to $100,000 in repairs. Radon testing (a naturally occurring radioactive gas) is recommended by Health Canada, especially in house basements. Vermiculite insulation containing asbestos, used before the 1990s, requires specialized removal. Each of these inspections costs between $100 and $500 but can save you considerable amounts.

The Inspection as a Negotiation Tool

The inspection report is a powerful negotiation tool. If the inspector identifies significant problems (roof at end of life, outdated electrical system, cracked foundation), the buyer has several options: request a price reduction corresponding to the estimated repair costs, require the seller to complete repairs before closing, or withdraw from the transaction without penalty if the inspection condition remains active. For first-time buyers whose budgets are often tight, the inspection enables an informed decision and prevents purchasing a property requiring unforeseen repairs beyond their means.

The Inspection and Mortgage Financing

Some lenders and the Canada Mortgage and Housing Corporation (CMHC) may require a satisfactory inspection as a financing condition, particularly for older properties or those purchased with less than 20% down payment. If the inspection reveals major problems, the lender may refuse financing or require repairs before disbursement. The appraiser commissioned by the lender may also flag visible issues that will require further inspection.

How to Choose a Building Inspector

Choosing the right inspector is critical to the quality of the report. Verify that the inspector is a member of a recognized professional association, carries professional liability insurance and has significant experience with the type of property you are purchasing (single-family home, condo, plex). Ask for a sample report to evaluate the level of detail. Avoid inspectors recommended by the seller or the seller's real estate broker, as there may be a conflict of interest. Your mortgage broker or buyer's real estate broker can recommend independent and reputable inspectors in your area.

What to Do After Receiving the Inspection Report

Once you receive the inspection report, review it carefully with your real estate broker and mortgage broker. Issues are typically categorized by severity: major defects requiring immédiate attention (structural problems, active leaks, unsafe electrical), moderate issues that should be addressed within the next few years (aging roof, outdated plumbing), and minor items that are routine maintenance. For major defects, obtain repair estimates from qualified contractors to support any negotiation with the seller. If the property requires significant work, factor these costs into your total budget and discuss with your mortgage broker whether additional financing options such as a purchase-plus-improvements mortgage might be available. Remember that your inspection condition in the purchase offer has a strict deadline, so act promptly to avoid losing your right to withdraw or negotiate.
