Calgary made the secondary suite mainstream. Suites are broadly permitted across the city, there's an official suite registry, and the city is waiving suite permit fees into 2026 — a genuine, time-limited saving.
Suites: the open lane
- Secondary suites (inside the house) and backyard suites (detached) are permitted uses across most residential districts.
- The suite registry gives legal suites a public record — which matters to lenders, insurers and tenants.
- Permit fees waived into 2026 — if a suite is on your list, the window is now.
Rowhouses & multiplexes: check your district
Calgary's 2024 city-wide rezoning opened rowhouse and multiplex potential broadly — but it's being wound back in 2026, so multi-unit potential now turns on your lot's specific district zoning. Some lots keep generous permissions; others revert. This is exactly the kind of moving target a current, address-specific check settles.
The money side
Alberta has no provincial sales tax, per-unit government charges are generally lighter than in Ontario or BC, and the federal purpose-built-rental GST relief applies here like everywhere else. Between the fee waiver and the lighter charges, Calgary's cost stack is one of the friendliest in the country.
