Do I need a gas permit to install a patio heater on my deck in Metro Vancouver?

Yes, you need a gas permit for any permanent gas line installation to a patio heater on your deck in Metro Vancouver. This work must be performed by a licensed gas fitter and inspected by Technical Safety BC (TSBC).

Permanent vs. Portable Gas Connections

If you're installing a permanent gas line from your home's natural gas supply to a built-in patio heater, fire table, or outdoor kitchen appliance, this requires a gas permit, licensed installation, and TSBC inspection. The gas fitter must be certified by Technical Safety BC, and the work cannot proceed without proper permits. This applies whether you're running a new gas line under your deck, through exterior walls, or extending an existing line.

Portable propane patio heaters that connect to standard 20-lb propane tanks with quick-disconnect fittings do not require permits — these are considered appliances, not gas installations. However, any permanent propane tank installation (like a built-in 100-lb tank with a regulator and permanent piping) does require permitting.

Metro Vancouver Requirements

Each municipality handles gas permit applications, but Technical Safety BC governs the actual gas work and inspection across all of Metro Vancouver. In Vancouver, Surrey, Burnaby, Richmond, and other municipalities, you'll apply for the gas permit through the local building department, but the gas fitter coordinates directly with TSBC for inspection scheduling.

Gas line installation costs typically range from $800-$2,500 depending on the distance from your existing gas meter, whether the line runs under the deck or through the house, and the BTU requirements of your patio heater. The permit itself costs $100-$300 depending on your municipality.

Safety Considerations for Deck Gas Installations

Gas lines under decks require proper protection from moisture and physical damage — especially critical in Metro Vancouver's wet climate. The gas fitter must ensure adequate ventilation around gas appliances (gas heaters produce carbon monoxide) and proper clearances from combustible deck materials. Overhead coverage like pergolas or deck roofs create additional ventilation requirements that TSBC inspectors will verify.

When to Hire a Professional

All permanent gas work requires a licensed gas fitter — this is not DIY territory. Even experienced contractors cannot legally install gas lines without proper TSBC certification. The gas fitter will handle permit applications, coordinate inspections, and ensure your installation meets BC gas code requirements.
