A garage suite (carriage suite) is a self-contained living space built above or beside a detached garage, and in Calgary it requires both a development permit and a building permit plus compliance with the Land Use Bylaw for height, setbacks, and parking. Built to code and registered, it can serve as a legal secondary suite for family or rental income.

A Garage Suite Pays for Itself
A garage suite — a living unit built above or beside a detached garage — is one of the best real estate moves in Calgary right now. Rental income, multigenerational living, or resale value: it all adds up.
What Calgary Allows
As of 2026, Calgary’s Land Use Bylaw allows garage suites (also called carriage suites or garden suites) in most R-1, R-CG, and many other residential districts. The City of Calgary actively supports secondary suites to address the housing shortage.
- Must be in a separate building from the main house (or above a detached garage)
- Max 45% of the principal dwelling size, or 50 m² (538 sq ft) — whichever is smaller — in some zones
- Requirements vary by land use district
- Separate entrance, separate utilities (or shared meter with sub-meter)
Design Options
Above Detached Garage
The most common option. Garage on the ground floor, suite above. Requires:
- 8’+ ceiling in the suite (9’+ preferred)
- Separate exterior stair access
- Fire separation between garage and suite
- Minimum 2-piece bathroom + kitchen + living area + bedroom
Beside the Garage (Side Suite)
Suite built beside the garage bay on the same slab. Slightly easier structurally, works on wider lots.
Permit Requirements in Calgary
- Development Permit (DP): Required for the new building/addition
- Building Permit: Required for all construction work
- Electrical Permit: Required
- Plumbing Permit: Required
- Gas Permit: Required (if gas heat)
Timeline: DPs take 6-12 weeks. Building permits 2-6 weeks. Plan for 3-4 months before breaking ground.

What’s Included in the Suite
A code-compliant garage suite needs:
- Minimum one bedroom
- Full kitchen (or kitchenette, depending on zone)
- 3-piece bathroom minimum
- Separate entrance
- Smoke and CO detectors, interconnected
- Fire separation from garage (Type X drywall, self-closing door)
- Heating system (in-floor or mini-split common)
- Sound insulation between floors (STC 50+)
Return on Investment
A garage suite renting at $1,800–$2,500/month in Calgary generates $21,600–$30,000/year. At a $350,000 build cost, that’s 6-8% gross yield — very strong for Calgary real estate. Plus the value added to the property itself ($200,000-$400,000 in some inner-city neighbourhoods).
