What Home Inspections Do You Actually Need Before Buying in BC?
A standard home inspection is just the start. In older Tri-Cities homes, the checks that save you the most money are the specialized ones — the oil-tank scan, the radon test, the sewer scope. Here's what to get, what it costs, and how it fits your subject clause.
Quick Answer
Almost every buyer should get a licensed whole-home inspection ($400–$900 in BC). Depending on the home's age and location, add targeted checks: an oil-tank scan on older Tri-Cities properties, a radon test, a sewer/perimeter-drain scope, and a closer look at poly-B plumbing, aluminum wiring or asbestos. In BC, home inspectors are licensed — use a licensed one — and build the inspection into your subject (condition) clause so you can walk away or renegotiate if something serious turns up.
Key takeaways
- Get a standard whole-home inspection on almost every purchase — $400–$900 in BC.
- BC licenses home inspectors — verify the licence before you hire.
- Older Tri-Cities homes can hide buried oil tanks, poly-B plumbing, aluminum wiring, asbestos or knob-and-tube.
- Consider add-ons: radon test, sewer scope, and an oil-tank scan.
- The inspection lives inside your subject-to-inspection clause — don't waive it lightly.
Before we start
I'm a REALTOR®, not a home inspector or an environmental specialist. This is general guidance on what to consider; the right scope depends on the specific property. Always hire licensed, qualified professionals and read their reports in full before removing conditions.
The standard home inspection
A general home inspection is a visual, top-to-bottom review of the home's major systems — roof, structure, foundation, electrical, plumbing, heating, insulation and more — with a written report flagging issues and their rough severity. In BC it typically runs $400 to $900 depending on the size and age of the home. It won't catch everything (inspectors don't open walls), but it's the single most valuable few hundred dollars a buyer spends, because it turns "looks fine" into a documented list of what you're actually buying.
Why BC licensing matters
British Columbia is one of the provinces that licenses home inspectors, so this isn't a case of "anyone with a flashlight." Ask for the inspector's licence, and favour someone with strong local experience — an inspector who knows Tri-Cities housing stock knows which era of home hides which problems. A cheap, unlicensed inspection is a false economy.

This is the big one people miss. Many older homes in Coquitlam, Port Moody and Port Coquitlam were once heated with oil, and decommissioned underground oil tanks can still be buried in the yard. A leaking tank is an environmental liability that can cost tens of thousands of dollars to remediate — and it can become your problem the day you take title. On any older home, it's worth having an oil-tank scan done to confirm there's no buried tank (or proper documentation that one was removed). It's a small cost against a potentially huge one.
Radon — worth a test
Radon is a naturally occurring radioactive gas that seeps up from the ground and can accumulate in homes, and parts of BC see elevated levels. It's invisible and odourless, and the only way to know is to test. A radon test is inexpensive relative to the health stakes, and if levels are high, mitigation is usually straightforward. On a home you plan to live in for years, it's a sensible add-on.
Sewer scope and perimeter drains
For older homes especially, a sewer scope — running a camera down the main line — can reveal root intrusion, cracks or collapses that a standard inspection can't see. The same goes for perimeter (foundation) drains, which can be original and near the end of their life. These are exactly the kind of hidden, expensive repairs that are far cheaper to discover before you buy than after your basement floods.
Red-flag materials to ask about
Certain building materials from past decades come with known issues, and a good inspector will flag them:
- Poly-B (polybutylene) plumbing — common in homes built roughly in the 1980s–90s and prone to failure; many insurers now ask about it.
- Aluminum wiring — used in some 1960s–70s homes; safe if properly maintained, but a factor for insurance and safety.
- Asbestos — possible in older insulation, flooring and popcorn ceilings; only an issue if disturbed, but important to know before renovating.
- Knob-and-tube wiring — in the oldest homes; often needs replacing and can affect insurance.
None of these is automatically a deal-breaker, but each can affect your insurance, your renovation plans and your price — so you want them on the table before you remove conditions.
New builds and condos still need a look
Buying new or buying a condo doesn't mean skipping due diligence — it changes its shape. New homes can still have deficiencies worth documenting (and warranty coverage worth understanding). For a condo, the "inspection" is as much about the strata documents — the depreciation report, minutes, budget and any planned special assessments — as it is about the unit itself. A great-looking suite in a poorly funded building is a risk a physical inspection alone won't reveal.
How it fits into your offer
In BC, you protect yourself by making your offer subject to inspection — a condition that gives you a set number of days to inspect and then decide whether to proceed, renegotiate, or walk away with your deposit intact. Waiving that condition to win a competitive offer is a real risk, and something to discuss carefully with your REALTOR® before you do it. Removing subjects is the moment your purchase becomes binding, so you want your inspection results (and any specialist reports) in hand first.
Frequently asked questions
Do I really need a home inspection in BC?
For almost every purchase, yes. A $400–$900 inspection turns a good-looking home into a documented list of what you're actually buying, and it's the basis for renegotiating or walking away if something serious turns up.
How much does a home inspection cost?
Typically $400 to $900 in BC, depending on the home's size and age. Specialized add-ons like a sewer scope, radon test or oil-tank scan cost extra but can save far more.
What is an oil-tank scan and do I need one?
It's a scan to detect a buried underground oil tank, common in older Tri-Cities homes once heated with oil. A leaking tank can cost tens of thousands to remediate and can become the new owner's liability, so a scan on older homes is well worth it.
Should I test for radon?
On a home you'll live in for years, yes. Radon is invisible and odourless, parts of BC see elevated levels, and testing is inexpensive relative to the health risk. Mitigation is usually straightforward if levels are high.
Do I need to inspect a condo?
Yes, but the focus shifts to the strata documents — the depreciation report, minutes, budget and any planned special assessments — alongside a look at the unit. A nice suite in an underfunded building is a hidden risk.
Can I waive the inspection to win a bidding war?
You can, but it's a real risk — you lose your main window to uncover expensive problems. Talk it through carefully with your REALTOR® first, and understand that removing subjects makes the purchase binding.
