Asbestos in BC Strata Buildings: What Pre-1990 Councils Must Do

An owner in a 1978 townhouse complex scrapes the stipple ceiling in their living room over a long weekend. No permit, no notice to council, no survey. On Tuesday the strata has a potential asbestos exposure across a shared attic space, a WorkSafeBC problem, and an argument about who pays for the testing.

If your building was constructed before 1990, assume asbestos is present until a qualified person has confirmed otherwise. That single working assumption prevents nearly every asbestos problem a BC strata encounters.

This article is general information about occupational health and safety requirements and the Strata Property Act, and is not legal advice. Asbestos work in BC is tightly regulated — engage qualified professionals rather than relying on a web page.

Why 1990 is the line

Asbestos was used in Canadian construction for decades because it is cheap, fire-resistant and durable. Its use was progressively restricted, and buildings constructed before 1990 are considerably more likely to contain asbestos-containing materials. Buildings from the 1950s through the 1970s are the highest risk, but the date is a guide rather than a guarantee — material stock lingered in supply chains, and renovations carried it forward into later decades.

The critical point about risk: asbestos in good condition, left alone, is generally not a hazard. The danger comes when it is disturbed and fibres become airborne — during demolition, renovation, drilling, sanding, or emergency work opening up a wall. Which is exactly why the question arises around projects, not around daily life.

Where it actually turns up in strata buildings

Councils tend to picture pipe lagging in a boiler room. The list is much longer:

• Textured or stipple ceilings — the classic residential source, and the one owners disturb during renovations
• Drywall joint compound and taping mud, which means ordinary walls, not just obvious materials
• Vinyl floor tiles, sheet flooring and the backing or mastic underneath
• Pipe, duct and boiler insulation in mechanical rooms and service shafts
• Vermiculite attic insulation, particularly in townhouse and low-rise complexes
• Cement board and pipe — soffits, siding, flues, transite ducting
• Roofing felts, shingles and flashing compounds
• Fire doors, gaskets, electrical panel backing and boiler rope

Note how many of those are inside strata lots rather than obviously in common property. That distinction matters for who pays, and it is the reason the strata plan is worth reading before anyone argues about it — see how to read a BC strata plan and common property vs limited common property.

What the law actually requires

Two obligations matter most to a council.

A hazardous materials survey before demolition or renovation. Under BC's occupational health and safety requirements, before work begins that could disturb building materials, a qualified person must inspect for hazardous materials including asbestos, and produce a written report. The owner of the workplace — the strata corporation, for work on common property — is responsible for ensuring this happens and for passing the information to contractors. A contractor who opens a wall without that information is being put at risk by the strata.

Licensed contractors and certified workers. Since 2024, BC requires asbestos abatement contractors to hold a licence from WorkSafeBC, and workers performing asbestos abatement to be certified. This is not a formality: hiring an unlicensed contractor for abatement exposes the strata as well as the contractor. Ask for the licence number and verify it.

Around those sit the ordinary owner-of-a-workplace duties — hazard information, prime contractor designation on multi-employer sites, and clearance letters. WorkSafeBC and your strata covers that framework in full, and asbestos is the single sharpest example of why it exists.

Build an asbestos register once, use it for twenty years

The most useful thing a pre-1990 strata can do is commission one good hazardous materials survey of the common property and keep the report permanently in the records.

A survey identifies suspect materials, samples and lab-tests them, records locations and condition, and produces a register. Costs vary with building size and how much destructive sampling is needed, but for a small building it is a low-four-figure exercise — trivially less than the cost of an unplanned stoppage mid-project.

What it buys you:

• Contractors get real information instead of a shrug, on every job for years afterwards
• Emergency work does not stall. When a pipe fails at midnight and the restoration crew asks whether the wall cavity is safe to open, the answer already exists
• Project budgeting becomes honest. Abatement is a real line item on envelope, plumbing and flooring work, and finding out during the project is how a budget becomes a special levy
• Owner renovations can be assessed against something factual

Keep the register current. Update it after abatement, and re-inspect the recorded materials periodically to confirm their condition has not deteriorated.

Manage in place, do not panic-remove

Removal is not automatically the right answer and is often the wrong one, because removal is the disturbance. Where material is in good condition and will not be disturbed, the standard approach is to manage it in place: record it, label it where appropriate, restrict access, inspect periodically, and require anyone working nearby to consult the register first.

Abatement is for when material is damaged, deteriorating, or in the way of planned work. It is done under containment by a licensed contractor, with air clearance testing before the space is returned to use.

Budget for it deliberately rather than reactively. Asbestos abatement on a major project belongs in the depreciation report's cost assumptions — if yours does not mention it and your building predates 1990, ask the consultant why. BC strata depreciation reports and the 2026 deadline covers the wider obligation, and what to do when the report says you are underfunded covers the consequences of an optimistic one.

The owner-renovation problem

This is where most stratas actually get burned, and it is entirely preventable.

Your alteration approval process should require, for any pre-1990 building, that an owner proposing work which will disturb ceilings, walls, flooring or mechanical services provides a hazardous materials survey of the affected area, and confirms that any abatement will be done by a licensed contractor. Make it a condition of approval, in writing, alongside the usual indemnity and insurance requirements.

Two reasons. First, an owner sanding a stipple ceiling can contaminate shared spaces and neighbouring units, and the corporation ends up managing the consequences. Second, unapproved alterations are already a bylaw problem — see who's responsible: strata vs owner repairs — and adding a health hazard to an unapproved alteration turns an enforcement letter into something considerably more serious.

Tell owners about this before they renovate, not after. An annual note with the AGM package costs nothing, and it converts an argument into a process. Owners are rarely being reckless; they simply do not know that a stipple ceiling is a regulated material, and nobody has ever told them.

Emergency work deserves the same forethought. When a supply line fails behind a wall in a 1974 building, the restoration contractor has to open that wall tonight, and the question of what is inside it arrives at the worst possible moment. A survey already on file turns that into a phone call rather than a stoppage.

Buying into a pre-1990 building

For purchasers and their advisors, the questions are short. Has a hazardous materials survey been done, and can I see it? Does the depreciation report account for abatement in upcoming projects? Do the minutes record any asbestos incident, stoppage or abatement work?

Silence on all three in a 1975 building is not reassuring — it usually means nobody has looked. Reading strata minutes before you buy and what to look for when buying a strata property cover the wider document review.

A short council checklist

• Confirm the construction year, and treat anything pre-1990 as in scope
• Commission a hazardous materials survey of common property if one does not exist
• File the report permanently and give it to every contractor before work starts
• Verify abatement contractors are licensed and workers certified
• Add a hazardous materials condition to your alteration approval process
• Include abatement allowances in project budgets and in the depreciation report
• Minute all of it, so a future council can show the care was taken

Frequently asked questions

Does my BC strata building contain asbestos? If it was built before 1990, assume so until a qualified person confirms otherwise. Asbestos was widely used in stipple ceilings, drywall compound, vinyl flooring, pipe and duct insulation, vermiculite, cement board and roofing materials, and the only reliable answer comes from a hazardous materials survey with lab testing.

Is a strata required to do an asbestos survey in BC? Before demolition or renovation work that could disturb building materials, a qualified person must inspect for hazardous materials including asbestos and produce a written report, and the owner of the workplace must give that information to contractors. Many stratas commission one survey up front and use it for years.

Who pays for asbestos testing in a strata — the owner or the corporation? It follows the usual dividing line. Work on common property is the corporation's cost. An owner's renovation inside their strata lot is the owner's cost, and your alteration approval conditions should say so before the work is approved.

Do asbestos removal contractors need a licence in BC? Yes. Since 2024 asbestos abatement contractors must be licensed by WorkSafeBC and workers performing abatement must be certified. Ask for the licence and verify it before awarding the work.

Should a strata remove asbestos it finds? Not usually. Material in good condition that will not be disturbed is normally managed in place — recorded, monitored and disclosed to contractors. Abatement is for damaged material or material in the path of planned work, and must be done under containment by a licensed contractor with air clearance testing.
