Backyard suite rules in Calgary

Council repealed citywide rezoning on April 8, 2026, effective August 4, 2026. About 99% of properties returned to their pre-2024 zoning. Backyard suites stay a permitted use in R-G and a discretionary use in all other districts. They are no longer allowed on properties with semi-detached homes, and a property can no longer have both a secondary suite and a backyard suite. Secondary suites became a permitted use in all low-density districts (Bylaw 26P2026).

The rules at a glance

Allowed?: Allowed only through a discretionary approvalCouncil repealed citywide rezoning on April 8, 2026, effective August 4, 2026. About 99% of properties returned to their pre-2024 zoning. Backyard suites stay a permitted use in R-G and a discretionary use in all other districts.

Secondary suites became a permitted use in all low-density districts (Bylaw 26P2026).
What it’s called: backyard suite
Maximum size: 75 m² floor area, excluding stairways and landings up to 2.5 m²
Maximum height: 7.5 m, stepping down near neighbouring properties
Approvals needed: A development permit is required in most districts, followed by a building permit. In R-MH a land use redesignation is required. Minimum lot width is 9 m, or 7.5 m on a corner or lane lot with 3 or more stalls. Setbacks are 1.5 m from the rear and 1.2 m from the side, with 5.0 m separation from the main house.
Typical timeline: About 60 days to development permit approval (city page)
Fees and charges: Not confirmed from an official source.
Parking: One tenant stall in addition to the property's required stalls; street and tandem stalls do not count. The repeal page says 'Backyard suites will have a parking requirement again.'
Tiny homes on wheels: Homes built on a chassis to RV standards are 'not certified for year-round accommodation' and are regulated as RVs. A tiny home on a permanent chassis is a manufactured home, needs CSA mobile home certification, and is allowed only in R-MH or S-FUD. A tiny home on a permanent foundation with full services, added to a lot with a single detached house, is treated as a backyard suite.

Incentives and programs

Backyard Suites Incentive Program
Active
Up to $15,000 for construction, plus 40% of underground servicing costs up to $20,000. An extra $7,500 for mobility-accessible design and $2,500 for projects needing no bylaw relaxations. Funded by $10 million from the federal Housing Accelerator Fund; first come, first served. No short-term rental licence is issued for 1 year per $10,000 received. Detached suites only. [4]

Notes and caveats

The incentive page does not say whether funds remain, so 'active' means the page is live. News reports give a launch date of March 2, 2026. A secondary source gives an 85 m² maximum size, but the city page says 75 m². A contractor claims development permit fees are waived through 2026; I could not confirm this. Lots that kept R-CG zoning have new limits for development after August 4, 2026: 10 m height and 55% lot coverage.

Why Calgary is rated Moderate

Allowed only through a discretionary approval gives a base rating of Moderate. No extra discretionary approval is recorded, so the base rating stands. How ratings work
