Do You Need a Permit to Replace a Hot Water Tank in Burnaby?

The tank goes at the worst possible time — a Sunday, no hot water, water spreading across the floor. Someone offers to swap it cash tomorrow. Before you say yes, it is worth knowing that in Burnaby that job needs a permit, and that starting without one doubles what the permit costs.

Burnaby requires a permit — there is no small-job exemption

The City is direct about it: installing, making changes to or upgrading any part of a plumbing system in single and duplex dwellings requires a Plumbing Gas Permit. A water heater is not a special case. Burnaby's own 2026 fee schedule lists a water heater as a plumbing fixture, alongside floor drains, dishwashers and backflow devices.

Some BC municipalities exempt a like-for-like fixture swap. Burnaby publishes no such exemption.

What it costs in 2026

From the City's schedule of plumbing permit and inspection fees, effective January 1, 2026:

• $121.00 for the first fixture, $67.00 for each additional fixture.
• $70.00 to remove a fixture and cap the piping, $18.00 for each one after.
• $146.00 to transfer a permit or record a change of contractor.

A straight tank replacement is the first-fixture fee. Against the price of the tank and the labour, the permit is the small number on the invoice.

The number that should actually worry you

Burnaby charges for re-inspections when work fails, and the scale climbs steeply:

• 1st re-inspection $72.00
• 2nd $314.00
• 3rd $620.00
• 4th $1,240.00
• 5th and each one after $1,553.00

Failing twice costs more than the permit and the first inspection combined. That is the real price of a cheap install, and it lands on the homeowner, not on the person who did the work and left.

Burnaby is one of the few cities where the gas permit is not provincial

This one catches people, including trades from outside the city. Technical Safety BC issues gas installation permits across most of the province — but not in Burnaby. Burnaby appears on its list of areas where the municipality holds gas jurisdiction, along with Vancouver, Richmond, North Vancouver and Maple Ridge.

If anyone tells you they will pull a provincial gas permit for a Burnaby job, that is not how it works here. It goes through the City.

The clearance rule that fails installs

Burnaby publishes a specific requirement on where a water heater can sit. Under the BC Gas Code an appliance must be installed so it is accessible for servicing, with a minimum service clearance of 24 inches (600 mm) to any side, top or bottom where service could be needed — more if the rating plate says so, or if 600 mm is not enough to actually remove a part.

The City adds that a heater installed behind a furnace or boiler must have enough access to be removed without disrupting ductwork, piping, appliances or construction. Measurements are taken from the outermost projection of the appliance after it is installed, not from the wall.

In a lot of Burnaby homes — post-war bungalows with tight mechanical rooms, and newer townhouses where the tank shares a closet with the furnace — that is exactly what a rushed swap misses.

What the code requires on every tank, permit aside

• It has to be strapped. The BC Building Code requires service water heaters to be secured against overturning wherever the seismic value exceeds 0.37. Burnaby sits at 0.806 — more than double the trigger. Worth knowing: the code says secured to the structure and does not prescribe a strap count or height, so anyone quoting an exact strapping recipe as BC law is repeating something else.
• A temperature and pressure relief valve, sensing element in the top 150 mm of the tank, keeping the water below 99°C. The discharge pipe must be rigid, slope downward, end above a drain with an air break of no more than 300 mm, and carry no thread on the outlet. No shut-off valve is permitted between the tank and the relief valve.
• Thermal expansion protection where a check valve or backflow preventer makes the system closed. An expansion tank is the usual way to do it; the code allows alternatives.
• A drain pan if the tank sits in a ceiling or roof space, or over a wood floor — at least 50 mm larger than the tank, with 25 mm walls and its own drain.
• Electric storage tanks are set to 60°C.

Who is allowed to do the work

Under the BC Building Code, plumbing work is done by someone holding a Canadian tradesperson's qualification as a plumber, an apprentice supervised by one, or the registered owner and occupant of a single detached dwelling working on their own home. A duplex owner does not qualify for that last route.

When you hire a licensed contractor, they pull the permit and book the inspection. Burnaby handles both through its online permits portal.

The short version

In Burnaby, replacing a hot water tank needs a permit. There is no like-for-like exemption, the first-fixture fee is $121.00 in 2026, and the gas side goes through the City rather than the province. The permit is cheap; the re-inspection ladder is not, and neither is a tank sitting in a closet nobody can reach. For the province-wide rules on replacement decals versus full installation permits, that is worth understanding before the old tank comes out. Our hot water tank team pulls the permit, does the install and books the inspection as one job.
