Strata water damage in BC: the deductible, the word “responsible”, and what your bylaws change
In British Columbia, a leak that starts in one strata lot can end with a bill for the strata corporation’s whole insurance deductible — and the Province says those deductibles run from six figures upward. Whether the owner has to pay it turns on one word in the Strata Property Act, responsible, and on what the strata’s own bylaws do with it.
This page sets out the Act’s insurance sections, the Province’s guidance to owners, what the Civil Resolution Tribunal and the courts have said about the deductible, and the regulator’s own account of why water losses are driving strata insurance. Ontario condominiums work differently and have their own page.
The short version
- The strata must insure common property, the buildings and original fixtures at full replacement value, against major perils including water escape.
- The deductible is a common expense — but the strata can sue an owner for it if the owner is “responsible” for the loss.
- The Province says an owner can be deemed responsible even if not at fault. A strata’s bylaws can raise that bar to negligence.
- The Province puts strata deductibles at $100,000 to $750,000 or higher. Owner insurance can cover some or all of it; nothing requires it to.
Strata words, and what they mean

What the strata must insure
Strata Property Act, S.B.C. 1998, c. 43, s. 149(1) · 2026
Section 149(4) requires full replacement value, except in prescribed circumstances, and cover against major perils. The Strata Property Regulation, s. 9.1(2), lists them — the same list as Ontario's, water escape included — and defines fixtures to include floor and wall coverings and electrical and plumbing fixtures. Current to September 22, 2026.
Water escape is on BC’s statutory list, as it is on Ontario’s. The difference is in the fixtures: the strata insures what the developer built or installed as part of the original construction. What an owner added later — the improvements — is theirs to insure under s. 161, along with contents and liability.
Insurance Bureau of Canada, Types of home coverage · 2026
IBC says the corporation's policy typically covers fixtures installed as part of the original or standard construction — flooring and wall coverings, lighting and plumbing fixtures — while the owner's policy typically covers upgrades and improvements up to a stated limit, contingency cover if the corporation's insurance is insufficient, and loss assessment cover for a share of losses on common property above the corporation's limit. IBC's glossary adds that an insured's obligation to pay a deductible is not based on whether the insured is at fault.
The deductible, and the word “responsible”
Strata Property Act, s. 158(1) · 2026
Section 158(2) then says this does not limit the strata corporation's capacity to sue an owner to recover the deductible if the owner is responsible for the loss or damage that gave rise to the claim. Section 154 requires the strata to review its insurance annually, report on it at each AGM, and inform owners and tenants as soon as feasible of any material change, including any increase in a deductible.
Province of British Columbia, Strata owner and tenant insurance · 2025
The Province's example: a dishwasher water hose that breaks prematurely and overflows in a strata unit, damaging common property and other lots — the owner can be deemed responsible. It is the single sentence most BC owners do not know until the letter arrives.
That is the default the Province describes, and it is harsher than it sounds. “Responsible” is not the same as “at fault”: a hose that failed on its own in your unit can make you responsible for a claim you did nothing wrong to cause. The Province’s companion page says the same thing: the owner does not have to be deemed negligent in order to be held responsible.
What your bylaws change
On appeal the court found the tribunal's decision reasonable and dismissed the appeal. So the Province's “even if not at fault” is the default, and a strata's own bylaws can raise the bar to negligence. The bylaws decide which rule applies to you. A 2023 summary in the CRT's report records a strata claim dismissed because it failed to prove the leak came from the owner's lot.
So there are two regimes in the same province. Under the default, responsibility without fault is enough. Where a strata’s bylaws say an owner must have been negligent, the Tribunal — upheld on appeal — has applied that narrower test. The strata still has to prove where the water came from: the CRT’s 2023–24 report summarises a claim dismissed because the strata failed to prove the leak originated in the owner’s lot.
The Standard Bylaws that apply where a strata has not replaced them require an owner to repair and maintain their strata lot, and prohibit an owner, tenant, occupant or visitor from causing damage, beyond reasonable wear and tear, to what the strata must repair or insure. Read your strata’s registered bylaws; they may say more.
How big the deductible is, and why
Province of British Columbia, Strata owner and tenant insurance · 2025
Published July 23, 2025. The Province adds that strata owner insurance can cover some or all of the cost of the strata deductible, and that the corporation's insurance does not cover personal liability, household contents, living elsewhere after a loss, or paying the strata deductible. Its companion page says deductibles depend on the number of units and the strata's claims history.
The share BCFSA attributed to water damage from plumbing leaks and failures — 56 per cent in 2018 alone. The same report says insurers responded by raising water damage and sewer backup deductibles, and that there is no requirement for strata owners to insure their share of the deductible.
The regulator’s own explanation connects the two: water losses spread further in denser buildings, water was a key driver of strata claim costs, and insurers raised water damage and sewer backup deductibles in response. The strata must tell owners and tenants of any increase in a deductible as soon as feasible, under s. 154 — that notice is the moment to check your own policy.
What your own policy needs
The Province is direct about the gap: the strata’s insurance does not cover personal liability, contents, living elsewhere after a loss, or paying the strata deductible, and strata owner insurance can cover some or all of that deductible. BCFSA noted in 2020 that nothing requires owners to insure their share of it. Four questions for a broker:
- Does my policy cover the strata deductible if I am found responsible — and up to what amount, against the strata’s current water deductible?
- Does it cover improvements the original developer did not install?
- Does it include loss assessment for losses above the strata’s limit?
- Does it include additional living expenses if the unit is unliveable?
The order when a leak starts
- Stop the water and tell the strata or its manager at once.
- Photograph the source before any repair; where the water started is what responsibility turns on, and the strata has to prove it.
- Call your own insurer, including about deductible cover.
- Ask for the bylaws in writing before accepting a deductible demand.
- Disputes go to the Civil Resolution Tribunal.

Questions people actually ask
Who pays the strata insurance deductible for water damage in BC?
The deductible is a common expense under s. 158(1) of the Strata Property Act, but s. 158(2) lets the strata corporation sue an owner to recover it if the owner is responsible for the loss. The Province says an owner can be deemed responsible even if not at fault or negligent.
How much is a strata insurance deductible in BC?
The Province says strata corporation deductibles can range from $100,000 to $750,000 or higher, depending on the number of units and the strata's claims history.
Can a strata charge me the deductible if the leak was not my fault?
Under the default, yes: the Province's example is a dishwasher hose that breaks prematurely. But where the strata's bylaws require negligence, the Civil Resolution Tribunal has applied that narrower test, and the court upheld it (Nacht, 2019 BCSC 1785).
What does strata insurance cover?
Common property, common assets, buildings on the strata plan, and fixtures built or installed by the owner developer, at full replacement value against major perils including water escape. It does not cover owners' contents, improvements, liability or the strata deductible.
Do I need insurance for the strata deductible?
Nothing in the Act requires it, as BCFSA noted in 2020, but the Province says strata owner insurance can cover some or all of the deductible if the owner is found responsible.
Where do strata water damage disputes go?
To the Civil Resolution Tribunal, BC's online tribunal for strata disputes.
