Renovate or rebuild? What Alberta's zoning order means for Calgary homeowners

What the province decided

On October 8, 2026, the Alberta government told Calgary to keep the low-density zoning it brought back when council repealed citywide rezoning this summer. The rules stay in place until the City finishes its review of the Land Use Bylaw, which is expected to wrap up in 2027.

As reported by CTV News, the order also asks Calgary to create a zoning overlay that identifies every property returned to its previous low-density district. Rules on housing types, building heights and parking stay as they are while the review runs.

Calgary Mayor Jeromy Farkas and Alberta Municipalities have both pushed back, so expect more debate. For anyone planning work in the next year or two, though, the practical message is the same. What your lot allows today is what it will most likely allow through 2027.

Why this matters if you own a home in an established neighbourhood

For a couple of years, many owners of older bungalows heard the same pitch. Sell to a builder, or knock the house down and put up a duplex or a fourplex. On most lots that went back to R-C1 or R-C2 in August, that option is now off the table for the foreseeable future.

If the house no longer fits, that leaves three realistic paths. You can move, rebuild a single home on the same lot, or renovate and add on. Each one makes sense for different people.

When renovating and adding on makes sense

• You like the neighbourhood, the lot and the trees, and the house is structurally sound.
• The foundation can carry a second storey, or the lot has room to build out at the back.
• You want to stay in the home while parts of the work are done, or you can phase the project.
• Your budget is better spent on space and finishes than on demolition and new servicing.

When a full rebuild is worth a look

• The foundation is failing or the house has major structural problems.
• Almost nothing in the existing layout works for you, so you would be paying to keep walls you plan to move anyway.
• The house needs everything at once, from wiring and plumbing to windows, roof and insulation.
• You are prepared to live somewhere else for the length of the build.

What an addition can do on a low-density lot

In St. Andrews Heights, a family of four had outgrown a two-bedroom bungalow but did not want to leave the street. Kay2 added a second storey of more than 800 square feet, with a primary suite and three bedrooms for the kids, and rebuilt the main floor around a new kitchen. The family kept their lot, their neighbours and their mature trees.

In Lower Springbank, Kay2 extended the main floor and gave the house an entirely new exterior with new windows, roof and doors. The project was a 2024 BILD Calgary Region finalist for Best Home Renovation with Addition.

Neither project needed a change of zoning. Both were designed around the height, coverage and setback rules for the lot.

What to check before you decide

• Look up your current land use district on the City of Calgary website. If your lot reverted from R-CG this summer, the limits on height and coverage may be different from what you were told a year ago.
• Have the foundation and structure assessed before anyone draws a second storey.
• Find out whether you plan a secondary suite or a backyard suite. Under the current rules a lot can have one or the other, not both.
• Get real numbers for both paths. Our renovation cost calculator and the free Calgary Renovation Cost Guide are a good place to start.
