Poly B in Nova Scotia
Everything this library knows about Nova Scotia: 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 2 Nova Scotia cities we profile, roughly 67,308 of 232,820 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.
