[Updated October 2026: This article was revised to reflect the repeal of blanket rezoning, which took effect on August 4, 2026. It was originally published on July 21, 2026.]
If you own property in Calgary or are considering a development project, rezoning may be part of the conversation, whether you expected it or not.
Rezoning, formally known as a land use redesignation, is the process of changing the rules that govern what can be built on a specific piece of land. It determines the types of buildings allowed, the density, the permitted uses, and the development standards that apply. In a city where zoning policy has shifted dramatically in recent years, understanding how this process works is more relevant than ever.
This article explains what rezoning means in Calgary, how the City’s land use districts are organized, what the blanket rezoning of 2024 changed and its subsequent repeal, and how the application process works when a property owner needs to pursue a redesignation.
What Is Rezoning In Calgary?
Every property in Calgary is assigned a land use district under the City’s Land Use Bylaw. That district defines what can be built on the property, what the property can be used for, and the specific development rules — such as height, density, setbacks, and parking — that apply.
Rezoning, which the City of Calgary formally calls a land use redesignation, is the process of changing a property’s assigned district to allow for a different type of development or use. If what you want to build or do with a property is not permitted under the current designation, a redesignation is the formal path to changing that.
This is not a minor administrative step. A land use redesignation requires a formal application to the City, review by planning staff and a commission, community notification, and ultimately, a public hearing and vote by City Council. The process exists because changes to a property’s zoning can affect the surrounding area, altering a community’s structure and influencing everything from traffic and parking to neighbourhood character and infrastructure demand.
Understanding Calgary’s Land Use Districts
Calgary’s Land Use Bylaw organizes the city into a wide range of land use districts, each with its own purpose statement, permitted and discretionary uses, and development rules. Understanding the district system is important because rezoning is fundamentally about moving a property from one district to another.
The major categories of districts include:
- Low-density residential districts, which cover the majority of Calgary’s established neighbourhoods. The 2026 repeal of blanket rezoning (see below) reinstated the low-density districts that existed before 2024, such as R-C1 (Contextual One Dwelling), R-C1L (Large Parcel One Dwelling), R-C1N (Narrow Parcel One Dwelling) and R-C2 (Contextual One/Two Dwelling), alongside R-CG (Grade-Oriented Infill). Each allows different housing forms and densities: R-C1 is primarily for single-detached homes, R-C2 adds semi-detached homes and duplexes, and R-CG allows rowhouses, townhouses and fourplexes.
- Multi-residential districts such as M-C1, M-C2, M-CG, M-G, and M-H1, which accommodate higher-density housing including apartment buildings and larger townhouse developments.
- Commercial districts such as C-N1 and C-N2 (neighbourhood commercial), C-C1 and C-C2 (community commercial), and C-COR1 through C-COR3 (commercial corridor), which govern retail, office, and service-oriented development.
- Mixed-use districts such as MU-1 and MU-2, which allow both commercial and residential uses in street-oriented buildings.
- Industrial, special purpose, and direct control districts, which apply to specific land uses that require tailored regulations.
Even within a single broad category like “residential,” the differences between districts are significant. A property zoned R-C1 and a property zoned R-CG may be on the same street, but the range of what can be built — and the approval process required — can be very different.
When someone applies for a rezoning, the application must identify the specific district being requested and demonstrate that the proposed change is appropriate for the site and its surroundings.
What Is Blanket Rezoning In Calgary?
In May 2024, Calgary City Council approved a citywide residential rezoning, commonly referred to as blanket rezoning. The policy, which took effect on August 6, 2024, automatically changed the zoning of more than 300,000 established residential lots across the city to R-CG (Residential Grade-Oriented Infill), replacing the various low-density residential designations that had previously applied to those parcels.
The intent was to address Calgary’s housing crisis by removing the requirement for individual land use redesignation applications before building multi-unit housing such as rowhouses, townhouses, and fourplexes. Under blanket rezoning, property owners and developers could apply directly for a development permit on most residential lots, bypassing the redesignation process that typically adds months to a project timeline.
The policy was part of the City’s broader Housing Strategy 2024–2030 and was one of the most debated planning decisions in Calgary’s history, with more than 730 speakers presenting during the public hearing before council’s 9–6 vote to approve it.
The 2026 Repeal
On April 8, 2026, City Council voted to repeal the blanket rezoning. The repeal took effect on August 4, 2026, restoring the low-density districts that existed before 2024. According to the City, 99 percent of properties returned to their previous zoning.
Some properties were exempt from the reversion, generally because a permit, subdivision or owner-initiated rezoning application was approved or submitted during the blanket rezoning period. The exact criteria are set out on the City’s Repeal of Citywide Rezoning page.
The repeal also reversed several rules that affect suites. A property can no longer build both a secondary suite and a backyard suite, backyard suites can no longer be built on properties with semi-detached homes, and backyard suites have a parking requirement again. For properties that remain zoned R-CG, rules such as maximum height and lot coverage were also tightened.
For property owners, the practical takeaway is that zoning now depends on each property’s individual history. Two properties on the same street may have different zoning, so confirming your property’s current zoning with the City’s find your land use tool is an essential first step before making any development decisions.
When Do You Need To Apply For Rezoning?
You need a land use redesignation when what you want to do with a property is not allowed under its current land use district. Common scenarios include:
- You want to build a type of housing that the current district does not permit — for example, building a rowhouse on a lot zoned R-C1, which primarily allows single-detached homes.
- You want to change the use of a property from residential to commercial, or from one commercial use to another that is not listed in the current district.
- You are planning a mixed-use development on a property that is currently designated for a single use.
- You want to increase the density, height, or lot coverage beyond what the current district allows.
- You are pursuing a subdivision that requires a different land use designation for the resulting parcels.
Since the repeal of blanket rezoning took effect on August 4, 2026, many property owners who had assumed R-CG applied to their lot may find that their property has reverted to a low-density district such as R-C1 or R-C2. If a rowhouse or townhouse development is still the goal, an individual rezoning application is required.
How Does The Calgary Rezoning Process Work?
A land use redesignation in Calgary follows a structured, multi-step process governed by the Municipal Government Act and the City’s Land Use Bylaw. The timeline and complexity depend on the scope of the proposed change and the level of community interest, but the core steps are consistent.
Pre-Application Inquiry And Preparation
Before submitting a formal application, the City recommends a pre-application inquiry with the Planning Department. This helps identify major issues with the proposal early, clarifies what technical information will be required, and gives the applicant a sense of whether the proposed redesignation aligns with existing planning policy.
For complex proposals, hiring a land planning consultant or engaging a land surveyor at this stage can help clarify site constraints, including boundary lines, topography, easements, and existing encroachments, before the formal application is prepared.
Application Submission And City Review
A complete application is submitted to the City’s Planning Services Centre, either in person or through the City’s ApplyCentral online portal. The application must include the proposed land use district, supporting documentation, and any required technical studies.
Once accepted, the application is assigned to the Development Applications Review Team (DART) and circulated to relevant City departments for review. Adjacent landowners are notified by mail and a notice posting is placed at the site to inform surrounding residents.
Calgary Planning Commission And Public Hearing
After the review period, the DART team prepares a recommendation — either for approval or refusal — and presents it to the Calgary Planning Commission (CPC). The CPC is a commission of members appointed by City Council that reviews land use redesignation applications and makes recommendations to the Council.
The application then proceeds to a public hearing at a Council meeting, where any member of the public may speak in support or opposition. This is the formal opportunity for community input, and the hearing can last from a few minutes for straightforward applications to multiple days for complex or contentious ones. City Council makes the final decision on whether to approve, modify, or refuse the redesignation.
