The Asbestos Survey Comes Before Demolition, Not After

What the regulation requires

The requirement lives in section 20.112 of BC's Occupational Health and Safety Regulation. Before work begins on demolition or salvage of buildings and structures, the employer or owner must inspect the site to identify asbestos, lead, other heavy metals, and toxic, flammable or explosive materials that may be handled, disturbed or removed. The results have to be available at the worksite. Anything hazardous that turns up has to be safely contained or removed.

WorkSafeBC's plain-language version is that prior to any renovation or demolition work, a qualified person must conduct a hazardous materials survey to identify potential hazardous materials at the worksite.

Read that again, because the wording matters. It says a qualified person. It does not say the homeowner's judgement, the contractor's experience, or a look under the basement stairs with a flashlight. Someone with the training to sample and interpret has to do it, and the report has to physically exist on site while crews are working.

There is a second half to 20.112 that gets overlooked. If hazardous materials are discovered during the work that were not identified in the original inspection, all work must stop until those materials are contained or removed. That clause is the reason a thorough survey up front is cheaper than a thin one. A stop-work order in week three of a kitchen demolition costs far more than the sampling would have.

There is no building-age cutoff in the rule

This is the part that surprises people, and it is worth being precise about because the internet is confident and wrong on it.

You will read that the survey applies to homes built before 1990, or before 1980, or before some other tidy year. The regulation contains no such threshold. It attaches the requirement to the work being done, not to the year on the building permit. A qualified person conducts the survey before renovation or demolition, and the age of the house is a factor that person weighs, not a gate that decides whether the rule applies.

In practice, age still tells you a great deal about what the survey will find. Asbestos was used in Canadian residential construction across a long stretch of the twentieth century, and the North Shore's housing stock is full of the relevant vintages. A Norgate rancher from the fifties, a Lynn Valley split-level from the sixties, an Upper Lonsdale house from the seventies: all of them are candidates.

But newer does not mean exempt. Material sitting in a warehouse gets installed years after it was made, and renovations layer new work over old. A 1994 house can hold asbestos in a section of pipe insulation left from a 1970s furnace that was never fully removed. That is precisely the situation the survey exists to catch, and the reason WorkSafeBC's own guidance is blunt: never assume a building material is free of asbestos, because you cannot tell by looking at it.

What changed on January 1, 2024

BC brought in a licensing and certification regime for asbestos abatement, and it took effect at the start of 2024. Two separate requirements came with it, and they apply to different people.

The first is the licence. Employers offering asbestos abatement services to others in relation to buildings must hold a valid WorkSafeBC licence. That covers asbestos abatement contractors and, importantly, renovation and demolition contractors doing this work for clients. WorkSafeBC publishes a searchable list of licensed contractors, so a homeowner can check a company before signing anything.

The second is certification, and it reaches further than the licence does. Any worker performing asbestos abatement work in relation to a building must be certified, and WorkSafeBC states this applies even in situations where a licence is not required. Certification follows the person; the licence follows the company.

The licence carries a set of exclusions worth knowing, because they explain why some firms on a job site hold one and others do not. Employers doing abatement on their own buildings, such as municipalities and school boards, do not need one. Prime contractors coordinating a multi-employer site do not need one if their own employees are not doing the abatement. And trades whose workers may disturb or handle asbestos without performing abatement work, electricians and plumbers among them, are not covered by the licensing requirement.

That last exclusion is not permission to be careless. An electrician drilling through a wall does not need an abatement licence, and also should not be drilling through asbestos-containing material without the survey having identified it first. The exclusion is about who needs a business licence, not about who is allowed to release fibres.

• Companies offering abatement to clients need a WorkSafeBC licence
• Individual workers doing abatement need certification, licence or not
• Both requirements took effect January 1, 2024
• WorkSafeBC maintains a public list of licensed contractors you can search
• A notice of project must be submitted to WorkSafeBC for asbestos work

What a survey actually involves

A consultant walks the areas the renovation will touch and takes physical samples of anything suspect. Samples go to a lab. The report comes back identifying which materials contain asbestos, at what concentration, and in what condition.

The scope follows the work. A bathroom renovation gets the bathroom, plus whatever the plumbing and electrical runs pass through to get there. A full gut gets the whole house. This is where homeowners sometimes try to save money by narrowing the scope, and it usually backfires: the moment a crew opens a wall outside the surveyed area and finds something questionable, 20.112 stops the job until it is resolved.

Two practical notes on sequencing. Book the survey before the demolition date, not on it, because lab turnaround is measured in days rather than hours. And get it done before the final scope is priced, because a positive result changes the abatement line in the budget and you want that number before you commit, not after.

If the survey comes back clean, you have a document that stays on site and a contractor who can proceed without a stop-work risk hanging over the schedule. If it comes back positive, you have a defined abatement scope, done by a licensed company with certified workers, before the rest of the trades arrive. Neither outcome is a disaster. The disaster is not knowing.

The homeowner question nobody answers cleanly

Homeowners ask whether any of this applies to them if they are doing the work themselves, and it deserves a straight answer about what is and is not clear.

The WorkSafeBC framework is occupational health and safety law. It governs employers and workers. WorkSafeBC's published licensing material sets out who must hold a licence and lists the exclusions, and homeowners working on their own home are simply not addressed in that material one way or the other. We could not find a WorkSafeBC page stating a homeowner exemption, and we are not going to invent one.

What is clear enough to act on: the moment you hire anyone, you are in the system. A contractor working on your house is an employer or an independent operator, and the survey requirement, the licensing rules and the certification rules all apply to that work. Most renovations worth doing involve hired trades at some point, so for most readers the question is academic.

The health side is not jurisdictional at all. Asbestos fibres do not check whether the person disturbing them is being paid. WorkSafeBC describes asbestos exposure as the leading cause of work-related death in British Columbia. If you are opening up a house of a certain age, test first, whatever the regulation does or does not require of you personally.

How this lands on a real North Shore project

On a whole-home renovation of a older North Shore house, the survey is one of the first things booked, ahead of the permit application in many cases, because a significant abatement scope changes both the budget and the schedule enough that the client should see it before the drawings are finalised.

The most common finding on the North Shore is flooring, then pipe insulation, then joint compound. Flooring and pipe insulation are usually straightforward to scope. Joint compound is the one that reshapes a project, because it is spread through every wall assembly in the house rather than sitting in one identifiable place, and a positive result there turns selective demolition into a much more controlled operation.

None of this is a reason to walk away from an older house. Character homes in Ambleside, post-war stock in Norgate, sixties builds through Lynn Valley: these get renovated successfully every year. The difference between a project that runs smoothly and one that stalls is almost always whether the unknowns were identified in week one or discovered in week six.
