Poly B in Prince George: how many homes are affected?
Prince George’s housing stock, read against the years Poly B was installed in Canada.
The 30-second answer
Roughly 30% of Prince George’s 31,790 occupied homes, on the order of 9,537 dwellings, were built in periods overlapping the 1978 to 1998 Poly B installation window. Not every home from those years got Poly B, and plenty have been repiped since, but this is the pool where it lives. The most common construction period in Prince George is 1961 to 1980.
When Prince George was built
Occupied private dwellings by period of construction, 2021 Census. Red bars overlap the Poly B era; the 1961 to 1980 bucket only partially overlaps and is weighted accordingly in the percentage above.
The city average hides the street-level story
A city-wide percentage flattens what actually matters: which side of town your house is on. Cities grow in rings and phases, so Prince George contains whole subdivisions built squarely inside the Poly B window alongside districts that predate it entirely. The address checker reads the census build-era data for the immediate area around any Prince George address, which is the sharper question to ask.
How to check a Prince George home
If your home was built or replumbed between 1978 and 1998, look where pipe is visible: unfinished basement ceilings, under sinks, at the hot water tank, and at the main shut-off. Poly B is usually grey, flexible, and stamped PB2110. The identification guide walks through it with photos, and the service line page covers the buried pipe from the street, which can be polybutylene too.
If you find it
Why it fails explains the chemistry, the insurer tracker shows what coverage looks like right now, and the cost guide has honest replacement ranges. Buying or selling in Prince George? The disclosure chapter covers the rules.
