Port Coquitlam — or PoCo, as it's known locally — developed heavily through the 1980s and early 90s, producing a high concentration of Poly B homes in neighbourhoods like Mary Hill, Citadel Heights, and Lincoln Park. The city's growth during the peak Poly B years means a large percentage of single-family homes and townhomes here still have their original grey supply lines. Many PoCo homeowners are only now encountering the insurance and resale consequences of a plumbing system that was installed 30–40 years ago.
Port Coquitlam's Residential Build Timeline
Port Coquitlam's residential boom tracked closely with the wider Tri-Cities growth pattern. Citadel Heights, one of PoCo's most recognizable neighbourhoods, was largely developed between 1985 and 1993 — the peak of the Poly B era. Mary Hill saw significant development through the same period. Lincoln Park's older sections date back even further into the early 80s.
The result is a city where a substantial portion of single-family housing stock is at or past the expected service life of its Poly B plumbing. Unlike some other materials that degrade predictably, Poly B can appear fine right up until it doesn't — which is why proactive replacement before a failure event is the recommended approach for any PoCo home in the affected build range.
- Citadel Heights: largely 1985–1993, peak Poly B era
- Mary Hill: mixed ages, high probability in 80s and early 90s sections
- Lincoln Park: early 80s builds — oldest Poly B in Port Coquitlam
- Oxford Heights: mid-80s development, high Poly B prevalence
Selling a PoCo Home with Poly B
Poly B is a common buyer's home inspection flag in Port Coquitlam's resale market. If you're preparing to sell a PoCo home built before 1995, you'll want to know whether it has Poly B before your buyer's inspector does. Options range from replacing before listing (which typically adds more to asking price than the replacement cost) to pricing to account for it and disclosing proactively. Either way, having a professional assessment and written report gives you the information to make a strategic decision rather than a reactive one.
