This is a follow up to this previous post which you might want to read as a backgrounder.
The control of rain penetration relies on the exterior layer (the wall cladding) of the building envelope assembly to resist all rain penetration. This requirement has always been a requirement of the building code no matter what the envelope detail is.
Well building envelopes didn’t resist rain penetration, and this was clearly a case of widespread building code violations by the builders and the residential construction industry, and indisputably the main cause of leaky condos.
Following the collapse of the New Home Warranty as a result of so many leaky condo claims, James Hoggan & Associates were engaged by the Urban Development Institute(UDI) for an expensive, but well funded, PR campaign to deflect the blame for leaky condos.
Launching the campaign in 1999, UDI issued a press release that September stating, “UDI believes the (building) code is a major cause of the problem”. Sure it was a problem; the builders were incapable of even meeting the minimum standard requirements (of the building code – as loose as they were).
The Coalition Of Leaky Condo Owners (COLCO) challenged UDI and the residential construction industry by preparing a motion in March 2000 calling for a complete moratorium on all new residential construction until the supposed cause (the building code) was fixed.
Despite many efforts by COLCO on behalf of owners, the residential construction industry continued to build under the same building code until the British Columbia Building Code changed on December 15, 2006 [for the design and construction of building envelopes for new home construction in accordance with the introduction of Part 9 (2007 Vancouver Building By-law)].
Considering that the BC Building Code didn’t change until 2006, demonstrates how successful the “building code” blame campaign really was in duping the public for the purpose of restoring confidence in the industry. In fact, many people unfortunately still don’t know the truth today; that is, building code violations are the main cause of leaky condos.
