A current planning guide to Calgary building, trade, secondary-suite, drawing, and approval costs before you finish a basement.
Checked on September 29, 2026 · Confirm current requirements with the City before applying.
A City of Calgary building permit for a new basement development costs $333.84 in 2026, all-in including the Safety Codes Council fee. For a typical basement project, total permit fees usually land between $500 and $1,500 once electrical, plumbing, and gas permits are included. The bigger line item is often professional drawings ($1,500–$3,500), which the City requires with your application. Full breakdown below.

| Building permit — alteration to a developed basement | $205.92 | Renovating an already-finished basement |
| Homeowner electrical permit | from $116.50 | DIY electrical work; most homeowners have their electrician pull this instead |
| Homeowner plumbing permit | from $116.50 | DIY plumbing work; most homeowners have their plumber pull this instead |

Fees are per the City of Calgary 2026 Building & Trade Permit Fee Schedule. Totals include the Safety Codes Council levy. Always verify current rates on the City's MyPermit portal before applying — fees are updated periodically.
Yes, in most cases. The City requires a building permit for first-time basement development, new or removed walls, new window or door openings, new electrical circuits, and new or relocated plumbing.
No permit needed for purely cosmetic work to an already-finished basement — paint, flooring, trim, and fixture swaps.
Secondary suites need the most paperwork: a development permit, a building permit, and separate electrical, plumbing, and gas permits — and the trade work must be done by licensed professionals. That's not optional.
The permit fee is the cheap part. Your application needs drawings prepared to the City's standard, and incomplete drawings are the number-one reason applications stall.
Budget the drawings as part of your permit cost, not as an afterthought.
Two time-sensitive programs are running right now:
If a legal suite is even a maybe in your plans, getting the permit side sorted in 2026 is the cheapest it will be.
The City's service target is about 7 days for a straightforward basement development or renovation application — but that's a target, not a promise, and it assumes your application (read: drawings) is complete on arrival. Realistically, budget 2–4 weeks from submission to approval.
Secondary suites take substantially longer because two approvals run in sequence: expect 4–8 weeks for the development permit plus 2–6 weeks for the building permit. Planning a legal suite to rent next spring? Start the paperwork in the fall.
The $333.84 permit is the cheapest insurance on the entire project. Unpermitted work in Calgary risks:
Skipping permits doesn't save money. It moves the cost somewhere worse.
How much is a basement development permit in Calgary in 2026? $333.84, all-in including the Safety Codes Council fee. That's the building permit for first-time development of an unfinished basement.
Do I need a permit to finish my basement in Calgary? Almost always, yes — first-time development, new walls, new windows or doors, new circuits, and new or moved plumbing all trigger the permit requirement. Cosmetic refreshes of an already-finished basement generally don't.
How much are electrical and plumbing permits in Calgary? Homeowner-pulled trade permits start at $116.50 each. In practice, most homeowners have their licensed electrician and plumber pull these as part of the job, and the cost is folded into the trade's price.
How long does a Calgary basement permit take? Budget 2–4 weeks for a straightforward building permit from submission to approval. Secondary suites take 6–14 weeks total across both required permits.
What does a secondary suite permit cost in Calgary? Roughly $400 for the development permit plus a building permit starting around $403.52 and scaling with construction value — but suite permit fees were waived until December 31, 2026, saving about $680.
Can I pull the permits myself as a homeowner? Yes — Calgary offers homeowner permits for building, electrical, and plumbing work on your own home. You still need drawings that meet the City's submission standard, which is where many DIY applications get stuck.
