3.5 ACH pass or fail in Vancouver

After 3 years of requiring 3.5 ACH in the VBBL, the City of Vancouver “decided that it was time to take off the training wheels with the airtightness course.”

What does it mean? It means that if the house doesn’t meet the 3.5 ACH at final testing, the final occupancy won’t be granted.

It’s always good to remember that the building code (or bylaw) is the minimum requirement by law. 3.5 ACH is the required minimum by law. The requirements will become more stringent over the years, so why no try to go below 3.5 ACH now?
