Item 2 — Erasing the Old Zoning Categories Entirely

Understanding what was deleted, why it was done, and what both sides say about it

What Happened

On January 1, 2025, the City of Calgary deleted Part 5, Divisions 2 through 8 of the Land Use Bylaw 1P2007 in their entirety. These divisions contained all the specific rules for the old single-family residential zones.

This followed the mass rezoning of August 6, 2024 covered in Item 1, which had already converted all properties carrying those designations to R-CG. The January 1, 2025 deletion completed that process by removing the underlying rulebooks those designations had relied on.

The Zones That Were Deleted

• R-C1 — Residential Contextual One Dwelling

• R-C1s — Residential Contextual One Dwelling with Secondary Suite

• R-C1N — Residential Contextual One Dwelling Narrow

• R-C2 — Residential Contextual Two Dwelling

• R-1 — Residential One Dwelling

• R-1s — Residential One Dwelling with Secondary Suite

• R-1N — Residential One Dwelling Narrow

• R-2 — Residential Two Dwelling

Those designations no longer exist anywhere in Calgary's Land Use Bylaw. They were not replaced with equivalent rules under new names. They were removed entirely.

What Did Those Divisions Actually Contain?

The Rules That Governed Each Zone

Each of the deleted divisions contained detailed rules governing a specific residential zone. Those rules covered:

• Permitted and discretionary uses: What could be built on a property as of right, and what required a discretionary application

• Parcel size and dimensions: Minimum lot widths, areas, and depths required for different types of development

• Building setbacks: How far a building had to sit from the front, side, and rear property lines

• Lot coverage: The maximum percentage of the lot a building could cover

• Building height: Maximum heights for different building types in each zone

• Parking requirements: Minimum numbers of parking stalls required per dwelling unit

• Landscaping requirements: Rules about how much of the lot had to remain as soft landscaping

Why These Rules Mattered

These rules collectively defined the physical character that each zone was intended to produce and maintain. They were the written standards against which development applications in those zones were evaluated. They also provided the legal reference points that residents and lawyers could point to when challenging a development application.

Why Did the City Delete Them?

Eliminating Redundancy

Once all properties carrying those designations had been converted to R-CG the old rules had no active properties to apply to. Leaving them in the bylaw would have created a large body of rules with no practical application, which could cause confusion for applicants, planners, and the public.

Legal Clarity

Having deleted designations still present in a bylaw can create ambiguity. Someone reading the bylaw might reasonably ask whether those rules still apply in any circumstances. Removing them entirely eliminates that uncertainty.

Streamlining the Bylaw

Calgary's Land Use Bylaw is already a very long and complex document. Removing several entire divisions simplifies it and makes it easier to navigate for planners, developers, lawyers, and residents.

Completing the Policy Intent

The blanket rezoning was intended to create a single consistent set of rules for low-density residential land across the city. Leaving the old zones intact even as inactive designations would have been inconsistent with that intent.

What Are the Concerns About This Decision?

Loss of a Legal Reference Point

Before the deletion residents and lawyers challenging a development could point to specific written rules in the bylaw that a proposal might violate. Those rules are now gone. Critics argue that the old single-family zone rules provided a clearer and more protective framework for established neighbourhoods, and that their deletion removes a layer of legal grounding that could have been used in future disputes.

Permanence

Deleting an entire section of a bylaw is a more permanent and harder to reverse step than simply rezoning properties. Critics argue that the deletion made the policy change much harder to undo:

• Rezoning can in theory be reversed by a future Council

• Rebuilding the detailed rule structures of the old zones from scratch would require significant work and political will

• The deletion removed the institutional knowledge embedded in those rules

Direct Control District Implications

Some Calgary properties are governed by Direct Control Districts, which are individual bylaws that often reference sections of the main Land Use Bylaw by number. The deletion of those sections created a technical problem for those properties. The City addressed this through a separate provision that froze those references as they stood on December 31, 2024. That fix is covered in detail in Item 13 of this guide.

Loss of Neighbourhood-Specific Context

The old zones were not identical to each other. Each had rules tailored to slightly different development contexts:

• R-C1 was different from R-C1s

• R-C1s was different from R-C1N

• R-C1N was different from R-C2

By deleting all of them and replacing them with a single R-CG designation critics argue the City removed the nuance that allowed different types of established neighbourhoods to be governed according to their specific character and circumstances.

The Timing Question

The deletion took effect on January 1, 2025, approximately five months after the rezoning took effect on August 6, 2024. During that window properties had technically been rezoned to R-CG but the old rules still existed in the bylaw. Some observers have questioned whether the deletion should have been delayed longer to allow communities, lawyers, and the development industry more time to understand and adapt to the new framework before the old one was removed entirely.

What Does This Mean in Practical Terms?

For Most Homeowners

For most homeowners the deletion of the old zones is not something they will notice in their daily lives. The practical effect of the rezoning was already determined by the August 2024 change to the zoning map. The January 2025 deletion was largely a technical completion of that process.

For Residents Challenging Development

Where the deletion matters most is in legal and planning disputes. If a resident or community organisation wants to challenge a development application the arguments available to them are now shaped entirely by the R-CG rules rather than by the more restrictive rules of the old single-family zones. That is a meaningful shift for anyone navigating the development permit or appeal process.

For Developers

The deletion removes any residual ambiguity about which rules apply to formerly single-family properties. All such properties are now clearly and exclusively governed by R-CG rules with no old zone rules to reference or argue around.

Key Facts

• Date the old zones were deleted: January 1, 2025

• Zones deleted: R-C1, R-C1s, R-C1N, R-C2, R-1, R-1s, R-1N, R-2

• What was in those zones: Detailed rules governing permitted uses, setbacks, lot coverage, building height, parking, and landscaping for single-family properties

• Why the City deleted them: To eliminate redundancy, create legal clarity, streamline the bylaw, and complete the policy intent of the blanket rezoning

• Primary concern among critics: Loss of specific written rules that provided a legal reference point in development disputes and that embedded neighbourhood-specific context

• Hardest hit by the deletion: Residents and lawyers seeking to challenge development applications on the basis of the old zone rules
