The short answer: if your renovation or demolition could disturb building materials, BC requires hazardous materials to be identified before work begins — and if your home was built before 1990, assume that means testing. 1990 is a risk-screening threshold, not a legal exemption. Here’s where the rule actually comes from, when it applies, and what skipping it costs.
Where does the 1990 rule actually come from?
Two places, and it’s worth knowing both because your contractor and your municipality will each cite their own:
| Authority | What it requires | When it bites |
|---|---|---|
| WorkSafeBC — OHS Regulation s. 20.112 | A qualified person must identify hazardous materials (asbestos chief among them) before renovation or demolition work | The moment any hired worker touches the structure |
| Your municipality | Hazardous materials documentation in the demolition permit process (specifics vary by city — confirm with your permit desk) | When you apply for a demo permit |
| WorkSafeBC — since Jan 1, 2024 | Anyone doing asbestos abatement must be certified, and abatement contractors must be licensed | If your survey finds asbestos that must be removed |
The 1990 threshold exists because asbestos was a standard ingredient in Canadian building products — drywall joint compound, ceiling texture, vinyl flooring, insulation, stucco, cement board — until the early 1990s, which is why pre-1990 buildings are treated as presumptively containing it. But read the regulation carefully: s. 20.112 contains no year exemption. The duty to identify hazardous materials attaches to the work, not the build year. A newer building usually clears that step quickly and cheaply because far fewer suspect materials exist — “built after 1990” is a reason to expect a lighter survey, not a reason to skip the question.
What counts as “renovating” for this rule?
More than most homeowners expect. The trigger is disturbing building materials, not the size of the project:
- Opening, moving or removing any wall or ceiling
- Scraping or repairing textured/popcorn ceilings
- Pulling up old flooring (the black mastic underneath is a frequent positive)
- Electrical or plumbing work that cuts into pre-1990 drywall
- Insulation top-ups or air-sealing in an attic with vermiculite
- Any water-damage repair that cuts into old material — insurance jobs are not exempt
What doesn’t trigger it: painting over intact surfaces, swapping fixtures without opening walls, cosmetic work that leaves materials undisturbed. Asbestos in good condition, left alone, is not an emergency — the rule is about disturbance.
What does compliance actually look like?
For a renovation, it’s a scoped pre-renovation hazmat survey: a certified surveyor — since January 1, 2024, asbestos surveying in BC requires WorkSafeBC’s Level S certificate — samples the specific materials your project will disturb, an accredited lab analyzes them (24–48 hours), and you get a written report. In the Fraser Valley this typically runs $350–$600 — full pricing breakdown in our 2026 cost guide.
For a demolition, it’s a full pre-demolition survey of the entire structure ($600–$1,000+), because everything comes down and everything counts.
Two outcomes:
- Everything negative: hand the report to your contractor and proceed. The report is your proof the work was legal — keep it with your permit records.
- Something positive: only the materials your project disturbs matter. Sometimes the plan routes around them (drywall over a positive ceiling instead of scraping it). When removal is required, it must be done by a WorkSafeBC-licensed abatement contractor — a legal requirement since January 1, 2024 — followed ideally by independent clearance testing.
What does skipping it cost?
The honest math, since “it’s my house” is a common objection:
- Schedule: contractors stop work when they hit suspect material with no survey. A stopped job waits for sampling, lab analysis, and possibly abatement scheduling — measured in weeks, during which your kitchen is a construction site.
- Money: an uncontrolled disturbance (dry-scraped ceiling, demoed wall) can contaminate the house through the ductwork. Professional decontamination after the fact runs well into five figures — versus a few hundred dollars of testing.
- Liability: exposing hired workers to asbestos is the exact scenario WorkSafeBC’s penalties exist for. And an unpermitted, undocumented demolition follows the property into its next sale.
The one genuinely good shortcut
Confirm your build year first — not because a post-1990 date exempts you (it doesn’t), but because it changes the scope of the conversation. For pre-1990 homes, assume sampling is needed and test only what the project touches: a single-material test answers a single question for $100–$150, and a scoped survey covers a whole renovation for less than most people spend on paint. For newer homes, a short call with a certified surveyor usually settles whether anything in your project’s path warrants sampling — often the cheapest step in the entire renovation.

Frequently Asked Questions
What exactly is the 1990 rule in BC?
It's a risk-screening guideline, not a legal exemption. WorkSafeBC's OHS Regulation (s. 20.112) requires a qualified person to identify hazardous materials before demolition or renovation work that could disturb them — the regulation itself contains no year cutoff. Because asbestos was used in BC building products until the early 1990s, pre-1990 buildings are presumed likely to contain it and warrant sampling; for newer buildings the identification step is usually much lighter, but that's the certified surveyor's call, not the calendar's.
Is the homeowner or the contractor responsible for the survey?
The obligation attaches to the workplace — in practice, the owner arranges and pays for the survey, and the contractor is required to have it before starting work. Reputable contractors will not open pre-1990 walls without the report, because their workers' safety and WorkSafeBC compliance depend on it.
Does the rule apply to small jobs like removing one wall?
Yes, if the work disturbs building materials in a pre-1990 structure. The survey scales with the job though — a scoped pre-renovation survey for a small project samples only the materials that work will disturb, which is why small-job surveys cost less.
What happens if asbestos work is done without testing?
Work is supposed to stop. WorkSafeBC can issue orders and penalties, unprotected workers may have been exposed, and dry-scraping or demolishing asbestos materials can contaminate the home — professional decontamination after an uncontrolled disturbance regularly costs more than a decade's worth of surveys.
I'm just doing the work myself. Does WorkSafeBC still apply to me?
The moment you hire anyone — a drywaller, a hauler, a demo crew — your project is a workplace and WorkSafeBC's rules fully apply. How the rules apply to a homeowner working entirely alone is a narrower legal question we won't pretend to settle here, and regulated disposal requirements apply no matter who does the work. The health risk of disturbing asbestos doesn't care who holds the scraper — testing first costs the same few hundred dollars either way.
