Permit rules by project

Pick the project that matches your work. These are starting rules for Chilliwack; property-specific zoning, heritage and trade approvals can still apply.

Decks

Confirm with city

Chilliwack’s current building-permit information provides the municipal route for deck work, but it does not give one deck threshold that applies to every property. Confirm height, attachment and zoning with the City.

Sheds & accessory buildings

Check size / scope

Chilliwack states that an accessory building over 10 m² requires a building permit; an accessory building under 10 m² still requires a siting permit.

Basement renovations

Depends on scope

Chilliwack lists improvements to unfinished areas of a dwelling among work requiring a building permit; the result for an existing finished basement depends on the renovation scope.

Interior alterations

Confirm with city

Interior-renovation requirements depend on what is changing. Cosmetic work can be treated differently from structural, plumbing, occupancy or fire-safety changes, so confirm the scope with the City.

Garages / carports

Confirm with city

Garage/carport permit requirements depend on size, attachment, zoning and construction scope; use the current Chilliwack permit route.

Plumbing / HVAC

Confirm with city

Plumbing and other trade work can require separate permits/inspections depending on scope; confirm the current trade-permit route with Chilliwack.

Retaining walls

Permit required

Chilliwack’s Building Regulation Bylaw states that no person may construct or structurally repair a retaining wall without a valid building permit.

Demolition

Permit required

Chilliwack requires a demolition permit process, including the City’s demolition/hazardous-risk documentation before demolition work proceeds.
