BC Home Inspection Checklist — What Inspectors Check, What It Costs, and What to Do Next

A professional home inspection in BC takes 2.5–4 hours, covers more than 400 checkpoints across 10 major systems, and costs $500–$850 on a standard Coquitlam detached home. It is not a pass/fail exam — it is a prioritized list of what works, what needs attention, and what rises to the level of 'walk away.' This page shows you exactly what inspectors check and how to read the report.

All BC home inspectors must be licensed under Consumer Protection BC and follow the CAHPI/ASHI Standard of Practice. Craig works closely with a short list of licensed Tri-Cities inspectors and has reviewed hundreds of inspection reports alongside buyer clients — both first-time and experienced move-up families.

The definition

Short answer: what a BC home inspection covers

A full BC home inspection covers the structure, roof, exterior envelope, plumbing, electrical system, heating and cooling, interior finishes, insulation and ventilation, built-in appliances, and site conditions (drainage, grading, trees, fences). The inspector examines visible and accessible areas only — they do not open walls, dig foundations, or certify anything. The output is a written report (typically 40–80 pages with photos) plus verbal walk-through at the end of the inspection.

Step by step

What to do after the inspection — the 5-step reply

  1. 1
    Read the full report within 24 hours. Most inspectors deliver the PDF the same evening. Mark every item flagged 'immediate' or 'safety hazard' as priority one.
  2. 2
    Get repair quotes on any big-ticket item. Licensed trades typically quote Coquitlam homes within 48 hours. You need real numbers to negotiate, not the inspector's ballpark.
  3. 3
    Decide: walk, renegotiate, or accept. On a subject-to-inspection offer, you have three legal paths — remove subjects (accept as-is), negotiate a price reduction or repair credit, or do not remove subjects (deal dies, deposit returns).
  4. 4
    If renegotiating, request specific dollar amounts tied to trade quotes — 'I want $12,000 off for the roof, based on the attached Mr. Roof estimate.' Sellers almost always counter, so start at the actual repair number, not a softer one.
  5. 5
    Sign the subject removal (or walk) by the deadline in your offer. Missed deadlines are treated as subject-not-removed in BC — the deal dies and the deposit returns. Every Coquitlam subject removal I do goes to the seller's lawyer with a signed subject removal addendum on the exact deadline day.

Craig's take
The inspection is not the end of due diligence — it is the middle. A good inspection report triggers 3 or 4 specialist reports — roofer, electrician, strata depreciation review, maybe an engineer on the foundation. I build two extra days into the subject period so my buyers can get real trade quotes, not panic at the 11th hour. Sellers respect the process because it makes the final 'yes' or 'no' real.

Frequently asked

Everything buyers and sellers ask Craig about this.

How much does a home inspection cost in Coquitlam?

For a detached home, expect $500–$850 depending on square footage and age. Larger homes (4,000+ sqft) or homes with detached structures (shops, coach houses) run $800–$1,200. Condos and townhomes typically run $400–$600.

How long does an inspection take?

Detached homes typically take 2.5–4 hours on site, plus 3–8 hours for the inspector to write the report. Condos and townhomes are usually 1.5–2 hours on site.

Can I attend the inspection?

Yes — and you should. The verbal walk-through at the end of an inspection is where inspectors share the context that never fits in the written report. Plan to be there for the full duration if possible, or at minimum the final hour.

What does an inspector NOT check?

Inspectors do not open walls, dig foundations, certify roofs, test water quality, test for mould (without a separate air sample), estimate repair costs in writing, or provide any warranty. They examine visible and accessible areas only and give a written opinion.

Do I need a separate inspection for a condo?

Yes. The condo inspection covers the unit itself — plumbing under sinks, electrical panels, windows, appliances, balcony drainage. The strata building envelope is covered by the strata's depreciation report, which your realtor should request alongside the inspection.

Are home inspections mandatory in BC?

No. They are an optional buyer protection used as a subject clause in the offer. That said, 80%+ of BC resale transactions include a subject-to-inspection clause and a written inspection report.

What is the '2-5-10' New Home Warranty?

BC's mandatory warranty on new homes built by a licensed residential builder: 2 years on labour and materials, 5 years on building envelope, and 10 years on major structural. It is registered with the builder's warranty provider (usually National Home Warranty or Travelers Canada).

Can I use an inspection report to break a deal?

Yes — that's exactly what the subject-to-inspection clause is for. If the report reveals material issues that were not disclosed, you can non-remove the inspection subject without penalty, and the deposit returns.

Is a pre-offer inspection worth the money?

In competitive offer-date situations, yes — a pre-offer inspection is the price of admission for going subject-free. On a $1.2M home, $700 for a clean pre-offer inspection that lets you go subject-free is often the difference between winning and losing.

Who pays for the inspection — buyer or seller?

The buyer pays, paid directly to the inspector at time of inspection or by e-transfer same-day. The seller is never obligated to pay for a buyer's inspection.
