Rear Home Addition Cost in Vancouver 2026
How Much Does a Rear Addition Cost in Vancouver?
A rear addition — extending the back of the house into the yard — is the most common type of home addition in Vancouver. It adds square footage without changing the streetscape, typically requires less structural work than a second storey, and delivers excellent functional improvements.
