Deck Permits in Cowichan Valley — What You Need to Know

If you're building a deck in the Cowichan Valley, you likely need a permit. Here's what the requirements look like under the Cowichan Valley Regional District and how we handle it on your behalf.

When a Permit Is Required

Under BC Building Code and CVRD bylaws, a building permit is required for any deck that is attached to a dwelling, any deck over 600mm (24 inches) above grade, and any deck that supports a roof or enclosure. Freestanding ground-level platforms below 600mm may not require a permit — but check with the CVRD before building.

What the Permit Covers

A deck permit requires engineered drawings or prescriptive code compliance documentation showing footing sizes and depths, post and beam sizing, joist layout, railing guard height and baluster spacing, and connection details to the house where applicable.

CVRD Application Process

Permit applications are submitted to the CVRD Building Inspection department. Processing time varies — typically 2–6 weeks depending on current volume. We coordinate permit applications as part of the project scope and build permit timing into the project schedule.

What Happens Without a Permit

Unpermitted decks create liability at sale. Insurers and lenders increasingly require permit history for significant additions. We don't build without permits where they're required — it protects you and protects us.

Cost of a Deck in Cowichan Valley

A standard residential deck in the Cowichan Valley typically runs $20,000–$55,000+ depending on size, material, and complexity. Written estimate before work begins, permit fees included in the project scope.
