Permit rules by project

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

Decks

Check size / scope

Coquitlam lists decks less than 0.6 m above grade among work that does not need a building permit and routes decks outside that exemption through the permit process. The exact 0.6 m boundary is kept conditional.

Sheds & accessory buildings

Check size / scope

Coquitlam says a building permit is not required for storage or garden sheds under 10 m²; larger accessory buildings are permit projects.

Interior alterations

Depends on scope

Major renovations and regulated changes require permits, while maintenance that does not affect structural or fire/life-safety performance can be exempt; the exact interior scope controls the result.

Walls / structural work

Permit required

Coquitlam lists structural repairs and work affecting structural or fire/life-safety systems among permit-required homeowner work.

Garages / carports

Depends on scope

Coquitlam requires a permit for accessory buildings, equipment rooms, sheds or detached garages over 10 m²; small storage/garden sheds have a published exemption.

Plumbing / HVAC

Depends on scope

Coquitlam’s Building Bylaw regulates installation, alteration and repair of plumbing, sprinkler, heating and gas systems; the required permit/inspection route depends on trade and scope.

Fences

Depends on scope

Coquitlam lists ordinary fences among work that does not require a building permit. Pool/hot-tub enclosure work follows a separate project path.

Retaining walls

Check size / scope

Coquitlam states that a retaining wall exceeding 1.2 m requires a building permit and professional engineering. Walls under 1.2 m are listed among no-building-permit work; the exact 1.2 m boundary is kept conditional.

Good to know in Coquitlam

  • Coquitlam accepts permit applications online. The City says residential drawings must identify the designer, civic address, scale and sheet sequence; project-specific checklists cover detached buildings, outdoor decks, secondary suites/basement finishes, and single- or two-family homes.
  • A retaining wall over 1.2 m is one of the exterior projects Coquitlam explicitly identifies as requiring a permit. Zoning still applies separately, and electrical or gas work can require its own approval route.
