Calgary permits guide
When you need a permit in Calgary for plumbing, electrical, gas, HVAC, building, decks, and fences. Who pulls it, what it costs, and what happens if you skip it.
Do I need a permit for trade work in Calgary?
Most plumbing, electrical, gas, HVAC, structural, and significant exterior work in Calgary requires a permit from The City of Calgary. Cosmetic work — painting, flooring, replacing fixtures with like-for-like — generally does not. The contractor doing the work is responsible for confirming permit requirements and pulling the permit before starting.

Who pulls the permit — homeowner or contractor?
The licensed contractor performing the work is responsible for pulling trade permits (plumbing, electrical, gas, HVAC) in Calgary. Homeowners can pull a Homeowner Permit for some types of work in their primary residence, but commercial work and rental properties always require a licensed-contractor permit.
When a contractor offers to do permit work without a permit — or asks the homeowner to pull a Homeowner Permit so the contractor avoids accountability — that is a red flag. The Homeowner Permit shifts liability to you, not the contractor. Use our verified contractor directory to find licensed trades who pull their own permits as a matter of course.
For DIY work in your primary residence, the City of Calgary Homeowner Permit covers basic electrical and plumbing work — but you become responsible for code compliance, inspection, and any failures down the road.
How the permit process works
The same six-step process runs for every trade permit. Trade permits typically issue within 1–2 business days. Building permits for renovations or additions take 2–6 weeks depending on scope.
- 1
Confirm your work needs a permit
Check the City of Calgary Development & Building Approvals website or ask your contractor. The line "is permit required?" is on every City of Calgary trade page.
- 2
Hire a licensed contractor (or qualify as a homeowner)
For plumbing, electrical, gas, and HVAC permits, the contractor must be licensed in that trade. Homeowners can pull a Homeowner Permit for some work in their primary residence.
- 3
Submit the permit application
The licensed contractor or qualifying homeowner submits via The City of Calgary contractor or homeowner portal. Most trade permits issue same-day or within 1–2 business days.
- 4
Pay the permit fee
Permit fees range from approximately $115 for simple electrical work to several thousand dollars for major building permits. Trade permits are typically $115–$300.
- 5
Have the work done
The contractor performs the work to current Alberta Building, Electrical, Plumbing, or Gas Code. Document the work — photos before drywall closes are smart.
- 6
Pass inspection
A City of Calgary inspector confirms the work meets code. Failed inspections require correction and re-inspection. The contractor coordinates this. Keep your inspection certificate — buyers will ask.
What happens if you skip the permit
Unpermitted work in Calgary can void your home insurance, fail at home-sale inspection, trigger removal orders from the City, and leave you personally liable if something goes wrong. The cost of redoing or pulling a retroactive permit usually exceeds the original permit fee by 5–10×.
Insurance companies routinely deny claims tied to unpermitted electrical, plumbing, or gas work. If a basement wiring job that was never permitted causes a fire, the insurance investigation will find the unpermitted work and the claim will be denied — leaving you with the cost of the rebuild.
At sale, buyers (and their inspectors) check the City of Calgary permit history at the property address. Unpermitted renovations often delay closing, reduce sale price, or kill deals outright. Pull the permit. The fee is worth it.
How to check past permits on a Calgary property
Search The City of Calgary Permit & Property Search at maps.calgary.ca/permits. Enter the property address to see all permits issued, their status, and inspection results going back several decades.
New homeowners should run this search before closing to confirm prior renovation work was permitted and inspected. Listing renovations in the MLS without a corresponding permit history is a sign to investigate further before you commit to the purchase.
