Poly B in New Brunswick
Everything this library knows about New Brunswick: 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 3 New Brunswick cities we profile, roughly 21,980 of 95,425 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.

Codes and permits in New Brunswick
New Brunswick adopts the National Plumbing Code 2020 province-wide under its plumbing licensing and inspection regulation. Plumbing is a licensed trade, and a provincial special homeowner’s permit exists for owner-occupants, though the big city permit counters state contractor-only, a discrepancy worth confirming locally.
