Calgary Commercial
Tenant Improvements

Map the complete approval sequence for your TI — building permit, development permit (if change of use), trade permits, and the Calgary inspection sequence — before your drawings go to the architect.

Where TI projects go sideways

Change of use triggers you didn't expect

Moving from retail to restaurant? From office to medical clinic? A change of use requires a Development Permit before the building permit review can conclude. Miss this and your timeline doubles.

Trade permits that run in parallel

Mechanical, plumbing, and electrical permits are separate applications — and they can often be submitted concurrently with the building permit, not after. Most teams sequence them wrong.

Inspection sequence matters

Rough-in inspection must pass before walls close. Final inspection must pass before occupancy. Inspectors won't open files out of sequence and will send your team home.

Typical approval workflow

Exact nodes depend on your project details. PermitPilot generates the specific graph after intake.
