Poly-B Plumbing Replacement: Planning and Paying for It

Polybutylene ("Poly-B") supply piping was installed in a great many BC buildings from the mid-1980s into the late 1990s. It has not failed everywhere, but insurers, engineers and depreciation report providers now treat it as an elevated water-escape risk — and that makes poly b replacement bc one of the most common big-ticket projects self-managed councils face.

This article walks through who is responsible for the pipes, how Poly-B affects insurance, and the funding routes the Strata Property Act actually provides.

Who owns the pipes?

Start with the plan and the Act, not with where the pipe happens to be visible.

Under the definition of common property in section 1, pipes and other service facilities are common property if they are located within a floor, wall or ceiling that forms a boundary between strata lots, or between a strata lot and common property — and also where they run wholly or partly inside a strata lot but are capable of and intended to be used in connection with another strata lot or the common property.

In practice that means:

• Risers, mains and in-wall branch lines serving more than one lot are usually common property.
• Fixture-level piping serving only that one strata lot, downstream of the boundary, may be the owner's responsibility.
• A building-wide repipe almost always touches both, plus drywall, tile and finishes.

The strata corporation's duty to repair and maintain common property comes from section 72, and bylaws can shift some responsibilities within the limits the Act allows. Because the split depends on your registered strata plan and your own registered bylaws, have both reviewed before you scope the project — tools such as SearchStrata can help a council read through plans, bylaws and engineering reports quickly, but the responsibility call is one to confirm with a strata lawyer or the project engineer.

Questions councils ask about Poly-B

Q: Does replacing Poly-B need a 3/4 vote?
It depends on how you are paying, not on the pipe. A special levy requires a 3/4 vote where each lot's share is calculated under sections 99, 100 or 195 — normally unit entitlement — under section 108. If you divide the levy in another way that establishes a fair division of expenses for that particular levy, section 108 requires a unanimous vote. A "3/4 vote" is defined in section 1 as 3/4 of the votes cast by eligible voters present in person or by proxy, excluding abstentions — not 3/4 of all owners.

Q: Can we just use the contingency reserve fund?
Sometimes with only a majority vote. Under section 96, CRF spending on repair, maintenance or replacement recommended in the most current depreciation report — of common property, common assets, or portions of a strata lot the strata has taken responsibility for under section 72(3) — needs only a majority vote. Any other CRF expenditure needs a 3/4 vote. That is a strong practical reason to make sure the repipe appears in your depreciation report. See the province's contingency reserve fund guidance and our CRF guide.

Q: What if a line bursts before the project is approved?
Section 98 allows spending without approval from either fund where there are reasonable grounds to believe an immediate expenditure is necessary to ensure safety or prevent significant loss or damage, and from the operating fund up to the limit in your bylaws (or, if the bylaws are silent, the lesser of $2,000 and 5% of the annual operating-fund contribution).

Poly-B and strata insurance

The strata corporation must insure common property, common assets, buildings shown on the strata plan, and original owner-developer fixtures on a full-replacement-value basis under section 149 — so the strata policy is not limited to common property. Owners insure their own improvements, non-original fixtures, liability and excess coverage under section 161.

What the Act does not do is set deductibles or require insurers to quote. Water-damage deductibles in Poly-B buildings are a market outcome, and they are the reason many councils accelerate replacement. Two rules matter:

• Under section 158, payment of a deductible on a claim against the strata's insurance is a common expense contributed through strata fees calculated under section 99(2) or 100(1).
• That does not limit the strata's capacity to sue an owner to recover the deductible where the owner is responsible for the loss. A chargeback to a responsible owner is that owner's liability in full and is not apportioned by unit entitlement — and responsibility is not automatic simply because water came from their lot.

Section 158 also provides that strata corporation approval is not required for a special levy or CRF expenditure to cover a deductible the strata must pay to repair damaged property, unless it has decided not to repair under section 159. The corporation must review insurance adequacy annually, report at each AGM, and inform owners and tenants as soon as feasible of material changes including deductible increases — section 154.

Funding the project

• Depreciation report first. Corporations of 5+ lots must obtain one by July 1, 2026 (Metro Vancouver, Fraser Valley, Capital Regional District) or July 1, 2027 elsewhere, renewed every five years and prepared by a qualified person — see the provincial requirements.
• Build the CRF. Since November 1, 2023, every strata and section must budget a minimum annual CRF contribution of at least 10% of the total budgeted operating-fund contribution, determined after considering the most recent depreciation report (Strata Property Regulation, ss. 3.4 and 6.1).
• Combine sources. Many councils fund a repipe with a CRF draw plus a special levy, phased by building or riser. Strata fees themselves are set by the budget and allocated by unit entitlement (section 99) — see How Strata Fees Work in BC and How to Prepare a Strata Annual Budget.

Your levy resolution must set out the purpose, the total amount, each strata lot's share and the due dates. General-meeting notice is at least two weeks, and notice sent by email, mail or fax is deemed received four days after sending — so an emailed package should go out about 18 days ahead. All BC stratas may hold electronic or hybrid general meetings without passing a bylaw, which helps turnout on a levy vote. Tracking quotes, resolutions and owner communications in one place — ManageStrata is built for exactly this kind of self-managed project — keeps the paper trail defensible.

If owners want to repipe their own lot early

Whether an owner can repipe ahead of the corporation depends on what is being altered. Standard Bylaws 5 and 6 require the strata's written approval before altering common property or the listed parts of a strata lot, and allow the corporation to require the owner's written agreement to take responsibility for the expenses relating to the alteration. Approval is given in writing — normally by council — not by an owners' vote, and Bylaw 5(2) says it must not be unreasonably withheld. Your own registered bylaws may go further, so check them.
