Poly B in British Columbia
Everything this library knows about British Columbia: the housing numbers, the code and permit reality, and what genuinely differs on this side of the provincial border.
The 30-second answer
Across the 23 British Columbia cities we profile, roughly 431,183 of 1,386,105 occupied homes were built in periods overlapping the 1978 to 1998 Poly B installation window. That’s the pool where Poly B lives, not a count of homes that have it, and the only way to answer for a specific home is to look at the pipe.

Money: what British Columbia offers
BC’s Rebate for Accessible Home Adaptations covers plumbing only when tied to an approved accessibility adaptation; a standalone repipe does not qualify. The grants and funding page has the full national picture.
Buying and selling in British Columbia
BC is the disclosure-statement province: the property disclosure statement is incorporated into the contract, the case law punishes games played with it, and strata depreciation-report deadlines now put building plumbing history in writing for much of the province. The disclosure chapter covers it in full, and the buyer’s guide walks the purchase side.
The essentials, wherever you are
The material itself doesn’t care about borders: identification works the same everywhere, the failure chemistry is national, insurer behaviour is tracked nationally, and real replacement costs come from over 1,500 completed jobs. Start with the address checker for any British Columbia address.

City figures aggregate to the provincial numbers above; both describe housing stock, never specific homes. Where British Columbia specifics aren’t verified, this page says so rather than guessing.
