Do You Need a Permit to Replace a Furnace or Water Heater in Sherwood Park?
Replacing a furnace or hot water tank is one of the most common home projects in Sherwood Park, and one of the most commonly misunderstood when it comes to permits. Some homeowners assume a “like-for-like” swap doesn’t need one. Others hear the rules from Calgary or Edmonton and assume they apply here.
This guide explains what Sherwood Park homeowners need to know: which jobs need a gas permit, who can apply for one in Strathcona County, how inspections work, and why skipping the permit can cause problems later.
Quick answer – Yes. Replacing a gas furnace, gas water heater, tankless water heater or gas garage heater in Sherwood Park requires a gas permit and an inspection, because the work involves gas connections and venting. Sherwood Park is part of Strathcona County, and the County issues gas permits through its online ePermits system. In most cases, the gas fitter doing the work applies for the permit. The County does allow homeowners to apply in some situations, but only for certain properties and project types.
Why permits exist for gas appliances
A gas furnace or water heater burns fuel inside your home. If the gas piping leaks, or the venting doesn’t carry combustion gases outside properly, the result can be a fire, an explosion or carbon monoxide in your living space.
A permit triggers an inspection by a Safety Codes Officer, who checks the work against Alberta’s codes. It’s an independent second look at the parts of the job you can’t easily check yourself: the gas connections, the venting and the safety devices.
Which jobs need a gas permit?
| Job | Gas permit needed? | Who usually applies |
|---|---|---|
| Replacing a gas furnace | Yes | The gas fitter |
| Installing a new gas furnace (new build, addition, basement) | Yes, and other permits may apply | The gas fitter (builder handles building permits) |
| Replacing a gas hot water tank | Yes | The gas fitter |
| Installing a gas tankless water heater | Yes | The gas fitter |
| Installing or replacing a gas boiler | Yes | The gas fitter |
| Installing a gas garage heater | Yes | The gas fitter |
| Installing a gas fireplace | Yes | The gas fitter |
| Electric water heater or electrical work | Not a gas permit, but electrical work may need an electrical permit | Check with the County |
If you’re unsure whether your project needs a permit, check with Strathcona County’s Building Regulation Services before work starts.
Who can apply for a gas permit in Strathcona County?
The County recommends that trades apply for their own permits. On its residential permits page, Strathcona County recommends that your builder applies for the development and building permits, and that the specific trades apply for the plumbing, private sewage disposal, gas and electrical permits.
Homeowners can sometimes apply. The County says that in some cases homeowners are eligible to apply for their own permits. If you own the home, it’s a detached single dwelling, and it is or will be your primary residence, you may be able to do the work yourself and apply for the permits as a homeowner.
But not for every home or project. Depending on the scope, some projects can’t be done by a homeowner. The County gives the examples of wiring over 100 amps, and trades work on homes that share common walls, such as duplexes, townhouses and secondary suites.
The rules differ in other cities. In Calgary, for example, a homeowner can only apply for a gas permit if they are an Alberta certified journeyman gasfitter working on a single-family home. Don’t assume advice from another city applies in Sherwood Park.
Our honest advice: even where homeowner permits are allowed, gas appliance work is best left to a certified gas fitter. The risks of a mistake are serious, and a professional installation keeps your manufacturer warranty on solid ground.
How the inspection works
Once the permit is issued and the work is done, the inspection is booked. Strathcona County explains the process as two steps:
- Request the inspection, either through the Building Regulation Services Inspection Line at 780-464-8169 or online through ePermits.
- Confirm the booking, either in your ePermits account or by calling the same inspection line.
A few things to know:
- You can’t request a specific time for the inspection.
- An adult (18 or older) must be on site when the inspector arrives. If the inspector can’t get in, a re-inspection fee may apply.
- There’s no additional inspection fee on top of the permit, but a rescheduling fee may apply if a booked inspection is missed.
When your contractor applies for the permit, they normally arrange the inspection too. Ask them to tell you when it’s booked so someone can be home.
What the inspector looks at
For a furnace or water heater replacement, the inspection typically focuses on:
- Gas piping and connections, including leak testing and shut-off valves
- Venting, whether a chimney connection, B-vent or PVC side-wall venting
- Combustion air, so the appliance can burn fuel safely
- Clearances around the appliance
- Safety devices, such as the relief valve on a water heater
- Condensate drainage on high-efficiency furnaces
Special situations in Sherwood Park homes
Upgrading from an old chimney-vented furnace
Many older Sherwood Park homes have a mid-efficiency furnace and a gas water heater sharing a metal chimney. A new high-efficiency furnace vents through PVC pipes instead, which can leave the water heater alone in a chimney that’s now too big for it. That “orphaned” water heater may vent poorly, and it’s exactly the kind of issue a proper installation and inspection should catch. See furnace replacement in Sherwood Park for what a full replacement should include.
Basement developments
Strathcona County’s basement development guidance includes rules for furnace rooms: a door must be provided to each room containing a furnace, the room must be supplied with the required combustion air, and the furnace must be enclosed in a room with a minimum 32-inch door. A building permit is required for most alterations within a home, and a gas permit is required to install a gas fireplace. If you’re adding heat to a new basement space, plan the furnace room and ductwork before the walls go up. See furnace installation in Sherwood Park.
Renovations and temporary heat
The Government of Alberta also has a rule for renovations: since May 1, 2017, a replacement furnace must not be used to heat a space that is undergoing renovation. Construction dust can damage a new furnace and affect its warranty, so plan temporary heat with your contractor if you’re renovating.
Switching to tankless
Moving from a hot water tank to a tankless water heater usually means a larger gas line, new venting and a condensate drain, all of which are covered by the gas permit and inspection. See tankless water heater installation.
What can go wrong if a permit is skipped?
- Safety. Nobody independently checks the gas piping and venting.
- Insurance. If there’s a fire, gas leak or water damage, an insurer may ask whether the work was permitted and inspected.
- Selling your home. Buyers, inspectors and lenders may ask for permit records for major mechanical work.
- Warranty. Manufacturers generally expect equipment to be installed by qualified professionals and to code.
- Fixing it later. Unpermitted work may have to be opened up, inspected or corrected down the road.

In most cases, the certified gas fitter doing the installation applies for the permit and arranges the inspection.
Do I need a permit to replace a hot water tank?
Yes, for a gas hot water tank. The replacement involves the gas connection, venting and safety devices like the relief valve, which the inspection checks.

Can I get a gas permit as a homeowner in Strathcona County?
Sometimes. If you own a detached single dwelling that is or will be your primary residence, you may be able to apply for permits as a homeowner.

Yes. A gas garage heater needs a gas line, venting and a gas connection, so it requires a gas permit and inspection like other gas appliances. Sizing and venting also matter for safety in attached garages. See garage heater installation in Sherwood Park.
What happens if my furnace was installed without a permit?
Talk to Strathcona County’s Building Regulation Services about your options. An inspection may still be possible, and any problems found can be corrected. Having the work inspected protects your family’s safety and avoids issues with insurance or when you sell your home.
