Hot Water Tanks in BC Stratas: Replacement Schedules and Leaks

A failed hot water tank is one of the most common sources of water damage claims in BC strata buildings — and one of the most common sources of arguments about who was supposed to replace it. The Strata Property Act does not mention water heaters at all, so the answer almost always turns on three documents: your strata plan, your registered bylaws, and your insurance policy.

Who owns the hot water tank?

Start with the boundary. Under section 68 of the Strata Property Act, a strata lot boundary sits midway through the structural portion of the wall, floor or ceiling unless the strata plan says otherwise. A tank sitting in a closet inside a strata lot is generally within the lot; a central boiler or a tank in a shared mechanical room is common property or a common asset.

The plumbing serving the tank is a separate question. The definition of "common property" in section 1 captures pipes and other facilities for the provision of water where they run inside a boundary wall, floor or ceiling, or run wholly or partially within a strata lot but are intended to serve another strata lot or the common property. So the tank can belong to the owner while the drain line, riser or vent it connects to does not.

Then check the bylaws. A strata corporation must repair and maintain common property and common assets under section 72, and may by bylaw take responsibility for specified portions of strata lots. Some stratas have done exactly that for in-suite hot water tanks; most have not. Nothing in the Act makes this universal — read your own registered bylaws rather than assuming.

Is there a required replacement schedule?

No. There is no statutory service life for a strata water heater in BC, and no provincial rule requiring replacement at a set age. This differs from fire and life-safety equipment, where each system carries its own BC Fire Code inspection, testing and maintenance interval — covered in our guide to fire and life-safety inspections.

What stratas do instead:

• Pass an age-based replacement bylaw. Many corporations require owners to replace in-suite tanks once they reach a stated age, sometimes with proof of installation. This is only enforceable if it is a validly passed and registered bylaw.
• Plan the common equipment. Central boilers, domestic hot water plant and recirculation systems belong in your maintenance program and in your depreciation report. Reports are required for strata corporations of five or more lots, due July 1, 2026 in Metro Vancouver, the Fraser Valley and the Capital Regional District and July 1, 2027 elsewhere in BC, renewing every five years and prepared by a qualified person.
• Track installation dates. Age data is only useful if it survives a change of council or manager — see strata maintenance planning and work orders.

A bylaw amendment must be approved at a general meeting by 3/4 vote and then filed in the Land Title Office; until it is filed, section 128 says the amendment has no effect. The corporation must inform owners and tenants as soon as feasible after approval. A 3/4 vote means 3/4 of the votes cast by eligible voters present in person or by proxy, excluding abstentions — not 3/4 of all owners (section 1).

Questions councils actually ask

Can we fine an owner who won't replace an aging tank?
Only if a registered bylaw requires replacement, and only after following section 135: written particulars of the complaint, a reasonable opportunity to respond including a hearing if requested, and written notice of the decision as soon as feasible. A fine imposed without those steps is void and cannot be fixed later.

Does the owner need approval to swap a tank?
It depends on what the work touches. Standard Bylaws 5 and 6 require the strata corporation's written approval before an owner alters common property or alters a strata lot in listed ways, including common property within the strata lot (Schedule of Standard Bylaws). A like-for-like replacement in the same location may touch nothing; relocating a tank, adding a drain pan tie-in or new venting often does. Approval is given in writing by the corporation — normally the council — not by a vote of owners, and bylaw 5(2) says it must not be unreasonably withheld. The condition the Standard Bylaws allow is the owner's written agreement to take responsibility for the expenses relating to the alteration.

Who pays the insurance deductible after a leak?
Two different outcomes. Payment of a deductible on a claim against the strata's insurance is a common expense under section 158, contributed through strata fees. Separately, the strata may sue an owner who is responsible for the loss to recover the deductible — that is the owner's liability in full and is not shared by unit entitlement. Responsibility is not automatic simply because the water started in that unit.

Paying for the repair

The strata corporation must insure common property, common assets, the buildings shown on the strata plan and original owner-developer fixtures on a full-replacement-value basis (section 149); owners can insure their own improvements, non-original fixtures, liability and loss of rental value under section 161. For the deductible itself, section 158(3) says strata corporation approval is not required for a special levy or a contingency reserve fund expenditure to cover a deductible the strata must pay to repair or replace damaged property, unless it has decided not to repair under section 159.

For the equipment replacement, sections 96 and 98 matter: CRF spending generally needs a 3/4 vote, but only a majority vote where the repair, maintenance or replacement is recommended in the most current depreciation report. And no approval is needed where there are reasonable grounds to believe an immediate expenditure is necessary to ensure safety or prevent significant loss or damage — the clause that covers a boiler failing on a Saturday.

Because so much depends on the wording buried in a bylaw amendment from 2014, tools like SearchStrata that run AI analysis across bylaws, minutes and reports can surface what your corporation actually decided. Keeping those records with the corporation matters too — ManageStrata is built on the idea that the management company can change but the strata's knowledge shouldn't.
