Gas furnace permits and inspections in British Columbia
The permit and inspection system for gas furnace work in BC: who issues permits, when they are required, what inspections verify, how it works for homeowners, and what to confirm before work starts.
Short answer
Gas work on a furnace in BC requires a gas permit, issued by Technical Safety BC or, in six municipalities (Vancouver, Richmond, North Vancouver, Maple Ridge, Burnaby and Kelowna), by the municipality itself; some municipalities add a heating permit. The contractor applies for the permit, the work is inspected, and homeowners should confirm both steps are part of the proposal.
Who issues gas permits in BC
Technical Safety BC issues gas installation permits across the province, except in the six municipalities that operate their own gas inspection systems: Vancouver, Richmond, North Vancouver (District), Maple Ridge, Burnaby and Kelowna. In those cities the contractor applies to the municipality instead.
The distinction matters at planning time but not at contract time: whichever body issues the permit, the contractor obtains it under its licence and books the inspection. Homeowners should see the permit as part of the proposal, not an optional extra.
When a permit is required
Installing, replacing or modifying a gas appliance and its gas connection requires a permit: a furnace replacement is gas work, and in some municipalities it also triggers a heating-system permit (Burnaby, for example, requires a gas permit and a heating-system permit for heating work in single and duplex dwellings). Adding a gas line, moving an appliance or converting fuel are all permit events.
Emergency repair work follows the same rules; the permit path is part of how the contractor closes the job, even when the call started at 10 pm.
What the inspection verifies
The gas inspection verifies the installation against the code and the permit: gas connections and pressure, appliance installation per the manufacturer's instructions, venting and combustion air, condensate handling, and safety-device operation. The commissioning record from the installation supports the inspection, which is why commissioning (combustion analysis, temperature rise, full-cycle testing) is part of the job this site describes.
What homeowners should confirm
- That the proposal states the gas permit (and any heating permit) is included and who applies for it.
- That the inspection is booked and closed out before the final invoice, or the terms are clear if not.
- That the installing contractor holds a Technical Safety BC gas contractor licence for the work.
- That any changes discovered during installation (venting route, condensate, gas line) stay within the permit scope or are re-permitted.

Questions people ask
Do I need a permit to replace my furnace?
Yes. Gas work requires a gas permit from Technical Safety BC or, in the six municipalities with their own systems, from the municipality. Some municipalities also require a heating permit.
Can I pull the gas permit myself as the homeowner?
Some jurisdictions allow homeowner permits for certain work, but a furnace installation is contractor work under a licensed gas contractor's permit in practice. BC Wide obtains the permits for the work it does.
What happens if furnace work was done without a permit?
Unpermitted gas work can be flagged at sale, insurance or inspection time, and must typically be inspected or corrected retroactively. If you suspect unpermitted work, have a licensed contractor review it.
