Calgary's 2026 Rezoning: What It Means for Basement Suites

Calgary's secondary-suite rules are changing in 2026: the blanket rezoning is set to be repealed effective August 4, 2026, and City Council has directed that secondary suites become a permitted use in all low-density residential districts. In plain terms, basement suites are moving toward being treated as a normal, expected use of a home rather than a special approval you apply for case by case. The details are still settling through 2026, so the most useful thing any homeowner can do is confirm what applies to their exact address before designing or pricing a suite. (This is general information, not legal advice — we verify the current rules for your specific property.)

What actually changed in 2026?

Two things happened, and it's worth separating them:

• The blanket rezoning is set to be repealed, effective August 4, 2026.
• Council has directed that secondary suites become a permitted use across all low-density residential districts.

The direction of travel is toward easier, not harder — suites being permitted uses means less discretionary back-and-forth for a lot of properties. But because the rules are in flux through 2026, we treat district-by-district specifics as something to verify, not to hard-code. We confirm the current requirements for your address as the first step of any suite project.

What makes a basement suite legal in Calgary?

Regardless of the zoning shifts, the safety and code fundamentals of a legal suite are stable. A legal basement suite needs:

• A separate entrance independent from the main dwelling.
• An egress window in every bedroom for safe exit.
• Fire and smoke separation between the suite and the main home.
• Independent heat for the suite.
• No maximum floor area — there's no size cap on a basement suite.

When a development permit is required, the review typically takes about 60 days. For the deeper distinction between a legal and an unpermitted suite, read legal vs. illegal basement suites, and see our full legal basement suite in Calgary guide for the requirements in detail.

Does this apply outside Calgary?

We build legal suites in Calgary, Airdrie, Chestermere, and Okotoks, and each municipality sets its own suite rules and permit process — Calgary's 2026 changes don't automatically carry over to the surrounding towns. That's another reason we confirm the rules for your specific address and municipality rather than working from a general assumption.

How we build suites (and what we don't do)

An important distinction: ReImagine builds legal suites as part of a full basement development — we take an unfinished basement and build a proper, code-compliant suite into it from the start, with the egress, separation, entrance, and mechanical systems designed in from day one. We don't retrofit or 'legalize' an existing finished basement, and we don't do standalone single items like just cutting in an egress window. Building it right from the start is what makes the suite safe, rentable, and something that holds up at resale or insurance time.
