Calgary Repealed Blanket Rezoning: What It Means for Secondary Suites

Does Calgary's repeal of blanket rezoning affect my ability to buy or build a home with a secondary suite?

Yes, but not the way most people assume. On August 4, 2026, the City of Calgary rolled back the citywide "blanket rezoning" that had reclassified most low-density lots to R-CG since 2024, allowing rowhouses and other multi-unit builds as-of-right. That part of the policy is gone for most properties. But in a separate decision made the same month, Council actually made secondary suites easier to build across the city, not harder. If you're counting on a suite for mortgage qualification or rental income, this update is good news, once you understand what changed and what didn't.

What Actually Changed on August 4

Calgary's "Rezoning for Housing" policy passed in May 2024 and reclassified most residential lots citywide to R-CG, a zoning district that permits rowhouses and similar multi-unit housing without a case-by-case rezoning application. Council voted to repeal it on April 8, 2026, and the change took effect August 4, 2026.

As a result, about 99% of affected properties reverted to the low-density zoning they had before 2024 (districts like R-C1 and R-C2). A property is exempt from reverting if it already had an approved R-CG, R-G, or H-GO permit or subdivision application, or had a rezoning application specifically applied for by the owner after August 6, 2024. You can check your own property's current zoning using the City's Find Your Land Use tool.

For properties that remain R-CG, or new R-CG development going forward, the rules got a bit stricter too: maximum building height dropped from 11m to 10m, maximum lot coverage dropped from 60% to 55%, and zero lot line developments are no longer allowed.

One change worth knowing if you're weighing suite options on a property: as part of the repeal, a property can no longer have both a secondary suite and a backyard suite at the same time. It's one or the other now. Backyard suites also lost some flexibility, they can no longer be built on properties with semi-detached homes, and a parking requirement is back in place for them.

The Part That Actually Matters for Suite Buyers

Here's the part that didn't get much attention in the general rezoning coverage. On July 21, 2026, in the same round of decisions, Council voted to make secondary suites a permitted use in every low-density residential district in the city, not a discretionary one.

That distinction matters more than it sounds like it should. A permitted use means that if your suite meets the rules in the Land Use Bylaw, it moves straight to a building permit. No development permit review, no discretionary approval process, no chance for a neighbour to appeal it. City administration estimated this saves up to six weeks of processing time and more than $600 in permit fees per suite, and expects it to result in roughly 2,300 new secondary suites built per year.

For context on why this was an easy call for Council: 98.9% of secondary suite applications in Calgary were already being approved in 2025, with 6,232 registered suites citywide that year. The discretionary review wasn't stopping suites from getting approved, it was just adding time and cost to something that was almost always going to happen anyway.

Backyard suites didn't get the same treatment. Council considered making those permitted too, but voted it down over concerns about size and consistency, so backyard suites remain discretionary in most districts (permitted only in R-G). If you're deciding between a basement suite and a backyard suite on a property, that difference in approval process is worth factoring in now.

What This Means If You're Buying With a Suite in Mind

None of this changes the fundamentals covered in Legal Secondary Suites in Calgary: What Buyers Need to Know or Priced Out of Calgary? How a Basement Suite Increases Your Mortgage Approval. A suite still needs to meet the same core requirements to be legal and to count toward mortgage qualification. What's changed is that adding or legalizing one just got faster and cheaper for a huge share of Calgary properties, since it no longer needs to go through a discretionary development permit.

If you're looking at a property with an existing legal suite, nothing here changes what you're evaluating. If you're looking at a property where you'd need to add or legalize a suite, this update works in your favour.

A Few Honest Questions People Ask

Do I need to do anything if my property was rezoned back in 2024? No. The City isn't requiring any action from property owners. It's worth checking your new zoning using the Find Your Land Use tool so you know what applies to your property going forward.

Can I still build a rowhouse on my lot now that blanket rezoning is repealed? Possibly, but you'd need an approved Land Use Redesignation from Council for a district that allows it, plus a development permit and building permit. It's no longer automatic.

Can I still have both a secondary suite and a backyard suite on one property? No. As of this change, a property can have one or the other, not both.

Does this affect a suite I've already legally registered? This update applies to the approval process for new or unregistered suites. If you have questions about how it applies to your specific property, the City's Suite Registry and planning department are the places to confirm.
