A bathroom "refresh" and a bathroom "renovation" can mean very different things to the City. Swapping a vanity faucet is one thing; moving a toilet is another. Here is what the City of Calgary says.
Plumbing permits
The City requires a plumbing permit when a plumbing system is constructed, extended or altered. A plumbing permit is not required to:
- repair a leak in a water distribution or drainage system;
- replace existing faucets and fixtures;
- remove a blockage in the drainage.
So replacing a toilet or vanity in the same spot generally doesn't need a plumbing permit, while moving a drain, adding a shower or converting a tub to a walk-in shower with a new drain location does.
Electrical and building permits
New circuits (for a heated floor, for example), new lighting circuits and fan wiring may need an electrical permit. Structural changes, like moving walls or cutting new openings, need a building permit. Cosmetic updates such as tile, paint and finishes on their own typically don't.
Homeowner permits vs contractor permits
Homeowners in Calgary can apply for their own plumbing and electrical permits only if they own and live in the home and do the work themselves. If you hire someone, they need to pull the permit. Homeowners can't pull homeowner electrical and plumbing permits for apartment-style condos; a licensed contractor must do that work.
Condos
If your bathroom is in a condo, check your bylaws first. Many boards require written approval, and the City asks for a letter of authorization from the condo board with building permit applications for units in a condo building.
Inspections
The City's plumbing inspections cover rough-in (drains, vents, water lines and the tub/shower valve installed before walls are closed) and final (fixtures ready to use, tub and shower temperature not exceeding 49°C, shut-off valves on toilets). Build the schedule around these so walls aren't closed too early.
Planning your project

Frequently asked questions
Do I need a permit to replace a toilet in Calgary?
Replacing an existing fixture does not need a plumbing permit, according to the City. Moving the toilet to a new location alters the plumbing system and does.
Do I need a permit for a tub-to-shower conversion?
If the drain or supply lines are altered, yes, a plumbing permit is required. Ask your contractor to confirm before work starts.
Who pulls the permit, me or the contractor?
Whoever does the work. Homeowner permits are only for owners who live in the home and do the work themselves.
