    The Calgary rezoning repeal, explained

    Four changes took effect August 4, 2026. If you researched backyard suites before that date, this is what is now different.

    What changed

    1. Since August 4, 2026, a property may have one of a secondary suite or a backyard suite — not both.
    2. Backyard suites are not allowed on semi-detached properties.
    3. The parking requirement returned.
    4. Backyard suites are permitted in R-G. In other zones they are discretionary and require City verification.

    What each change means in practice

    One suite type per property

    A property may have a secondary suite or a backyard suite, not both. If a home already has a basement suite, the backyard suite question is settled unless that changes.

    No backyard suites on semi-detached properties

    Semi-detached properties are excluded. This is the first thing to establish when you look at a property.

    Parking requirement returned

    Parking is a site-planning constraint again, and it competes with setbacks and the required outdoor amenity area for the same rear yard.

    Permitted in R-G, discretionary elsewhere

    R-G is where a backyard suite is a permitted use. Other zones — including R-CG and H-GO — are discretionary and require verification with the City. Do not treat any zone other than R-G as an automatic yes.

    What to do about it

    Re-screen any property you were considering: run the feasibility screening, then read the current rules and permit process. Confirm everything against the City's own rezoning project page.

    Screening only — not an approval. This is a screening tool, not an approval. Nothing on this page confirms that a backyard suite can be built on a specific property — only the City of Calgary can do that through the development and building permit process.
