In British Columbia, regulated gas work is done by someone holding a certificate of qualification for it. That is a rule, not a trade preference. The regulation does carry one exception for homeowners, and it is narrower than most people assume — narrow enough that it rules out a large share of Metro Vancouver's housing before you ever pick up a wrench.
The rule, in one line
The Gas Safety Regulation says an individual must not perform regulated work on a gas system or gas equipment unless they hold a certificate of qualification, or fall inside a short list of exemptions written beside it. The regulation was last amended on May 1, 2025, so this is current law, not an old convention the trade repeats. One of those exemptions is the homeowner, and it comes with conditions.
A homeowner may apply for an installation permit to perform regulated work with respect to gas equipment in a fully detached dwelling if (a) no person is being paid to do, or assist the owner in doing, the work, and (b) no part of the dwelling is rented to any person.
Read that exception slowly
Every clause in it is doing work. Fully detached rules out the strata townhouse and the condo. Paying nobody to assist rules out the friend you are covering for the day. And no part of the dwelling being rented is the one that catches people here, because a basement suite is ordinary housing stock across Burnaby, Vancouver and New Westminster. The permit is not optional either: the exception is a route to applying for one, not a route around it.
- Check the dwelling is fully detached.
- Own it and live in it.
- Rent out no part of it, basement suite included.
- Pay nobody to help, not even for an hour.
- Apply for the installation permit before you start.
A rented suite ends the exception
A basement suite is the most common reason a Metro Vancouver house falls outside it. A strata townhouse, a duplex, a condo and a laneway house you rent out are outside it too.
Servicing is regulated work too
Most people read the rule as being about new lines. It is not. Technical Safety BC's bulletin on annual servicing, issued May 19, 2010 and still its standing advice, says servicing and maintenance of gas appliances should only be carried out by a certified gas fitter employed by a licensed gas contractor. The same bulletin asks you to have all home heating devices serviced annually, whatever the fuel, because appliances that are not running correctly produce carbon monoxide.
Which jobs need a permit
Generally: new gas lines, appliance installations and connections, fireplace installation, furnace and boiler replacement, meter and regulator relocation, and alterations to an existing system. Installation permits themselves are issued to licensed contractors doing regulated gas work — the homeowner route above is the separate path, and it exists precisely because the ordinary one runs through a contractor.
What the inspection is actually looking at
Venting comes first: whether combustion products are leaving the building the way they should. That is a carbon monoxide question, and it is the single reason the inspection exists in the shape it does. After that come combustion air, which often fails in a space that has been sealed or insulated since the appliance went in; pipe sizing and materials against the connected load; pressure and leak testing; shutoff valves present and reachable; clearances to combustibles; and whether the appliance installed is approved for use here.
If the work in your house was never permitted
It is common, and it is not a crisis. You do not have to retroactively permit old work. What matters is that the next piece of work is done properly, because that is when anything incorrect gets found and corrected. It is occasionally why a job in an older home costs more than a phone quote suggested, which is worth knowing before the work starts rather than during it. At resale it can surface in a permit search or a buyer's inspection and become a negotiation. On an insurance claim, an insurer may have a view, and a claim is a bad moment for that to become a live question.
Ask one question before you book
Ask it directly: is the permit included, and will the work be inspected? A quote noticeably cheaper than the others is often a quote without a permit in it, and the gap is usually the paperwork rather than the pipe. A company that works this way answers the question without hesitating.
