This page summarizes New Westminster permit information. Use the official city links for the current rules on your address and project.
New Westminster’s published permit rules, in plain English:
New Westminster says owners planning to renovate, add to or build a detached dwelling must obtain the applicable permits.
The city provides a dedicated alterations-and-small-projects permit route and separate guides for decks, garages, secondary suites and detached accessory dwellings.
New Westminster administers local building approvals within British Columbia's code framework. See the BC permit overview for province-wide context; trade permits and local zoning still depend on the project.
