Navigating Calgary's Middle Housing Landscape Post-Blanket Zoning Repeal

By Stephen Barnecut

Calgary’s housing policy environment has experienced significant shifts over recent years. Middle housing—low-rise multi-family options like rowhouses, townhomes, and duplexes—remains at the centre of discussions surrounding density, affordability, and urban infill.

The Rise and Fall of Blanket Rezoning

In response to acute housing supply shortages and surging population growth, Calgary City Council approved a citywide land-use amendment in mid-2024. This "blanket rezoning" policy automatically converted standard low-density residential zones (such as R-C1 and R-C2) to R-CG (Residential – Grade-Oriented Infill). The objective was to eliminate planning friction, allowing rowhouses and secondary suites to be built across established neighborhoods without requiring site-by-site land use approvals.

However, public pushback over neighborhood character, infrastructure capacity, and property values led to a political reversal. Following a repeal decision, the blanket zoning policy officially came to an end on August 4, 2026. The city reverted to its previous framework, requiring property-specific applications for multi-family rezoning.

The New Path: Land Use Amendments, Policies, and Public Hearings

With blanket rezoning repealed, developers seeking to build middle housing on parcels zoned R-C1 or R-C2 can no longer proceed directly to building or development permits. Instead, the process now requires a full Land Use Amendment (rezoning):

  • Policy Amendments: Proposals must align with local Area Redevelopment Plans (ARPs) or Local Area Plans (LAPs). If a proposed R-CG conversion conflicts with existing community guidance, applicants must submit a concurrent policy amendment.

  • Public Hearings & Council Approval: Every Land Use Amendment requires a formal public hearing before City Council. Community members and adjacent property owners are given the opportunity to present arguments for or against the project. Council holds the final binding vote on whether to grant the R-CG designation.

Permitted Uses and the SDAB Advantage

Once a property is successfully designated as R-CG, the restored development permit process offers distinct operational advantages. Under the Land Use Bylaw, rowhouse developments in an R-CG zone are classified as a permitted use, meaning approved development permits cannot be appealed to the Subdivision and Development Appeal Board (SDAB) by neighbours if the proposal strictly complies with all rules.

However, a permitted use rowhouse not only has to meet all the rules under the R‑CG district, it has to further meet the following requirements:

  • Façade Articulation: Each unit requires either a street-facing projection/recess (min. 2.0 m wide, 0.3 m deep, 2.4 m high) or a street-facing porch (min. 2.0 m wide, 1.2 m deep).

  • Main Floor Elevation: Main floors facing a street must sit above grade, up to a maximum of 1.20 m.

  • Corner Entrances: Corner parcels must have exterior entrances visible from each street side.

  • Garage Restrictions: Attached private garages are prohibited.

  • Parking Access: Each dwelling unit must have a parking stall or private garage with direct, individual lane access.

  • Side Window Privacy: Windows on exposed side façades extending past the rear façade of a contextually adjacent building are prohibited unless located below the second storey, using fully obscured glass, set at least 1.5 m above the finished floor, or set back at least 4.2 m from the side property line.

  • Grade Differential: Slope across the site cannot result in a difference greater than 2.4 m between average building reference points.

  • Heritage Exclusion: Sites within a heritage guideline area do not qualify.

  • Building Depth: On non-corner parcels, depth cannot exceed the greater of 60.0% of the parcel depth or the contextual building depth average.

  • Single Main Building: Parcels cannot contain more than one main residential building.

Permit Volume Trends

Data from the City of Calgary’s Open Data Portal tracks the rapid shift in development permit application volumes before and after the decision to repeal. While applications were consistent from the middle of 2024 to the middle of 2026, they peaked in February and March 2026 driven by builders rushing to lock in approvals under streamlined rules before the scheduled repeal. Following the repeal decision, new R-CG development permit submissions plummeted to less than a handful per month. While there are broader market factors, this drop mainly reflects the friction of returning to individual council hearings for each project.

Why Expertise Matters More Than Ever

Under blanket rezoning, technical compliance with the land-use bylaw was often sufficient to advance an infill project, but under the restored framework, a project’s success depends heavily on the initial Land Use Amendment stage. Because applications now face public scrutiny at Council hearings, the expertise and track record of the design team and planner have become critical.

Skilled designers and planners are essential for crafting contextual built-form proposals that respect setbacks, privacy, massing, and streetscapes to proactively mitigate community concerns. They also play a vital role in presenting sound planning justifications that demonstrate alignment with high-level Municipal Development Plan (MDP) goals, while effectively navigating the public hearing process to address technical questions from Council members and secure elected officials' votes. While securing middle housing in Calgary now requires navigating additional regulatory steps, well-designed projects backed by experienced planners continue to find viable pathways through the city's planning framework.

Trent Letwiniuk Memorial Endowment

The late Trent Letwiniuk, Principal and cofounder of Inertia, was a graduate of the Architectural Technologies Program at Southern Alberta Institute of Technology (SAIT).

In his honour, Inertia’s sister company Gravity Architecture has created an endowment with SAIT so that at least one student each year will be granted an award.

The students will be in the Architectural Technologies Program in the School of Construction, enrolled in their second year, have financial need, and be interested in a career in residential design.

Our team at Inertia continues to include many SAIT graduates, and we are proud to be able to permanently support this program that has in many ways made the success of our firm possible.

While Gravity initiated and supported the initial endowment, anyone who wishes to contribute to it may do so by contacting SAIT by email at giving@sait.ca or by phone at 403.774.5214.

Inertia welcomes Gord Alexander to the team!

Upon graduating from SAIT Polytechnic’s Architectural Technologies program in 2003, Gord began his career at Cutforth Technologists where he focused on completing plans for hotels all over rural Alberta as well as custom summer homes at some of our popular lake communities.

Gord then moved into the residential world full time when he started at Albi Homes where he did all aspects of design from custom homes, site construction supervision, and management . As part of the product development team they were the recipients of several local and national SAM awards for design excellence. During his time here, Gord also completed the Lean Construction Program which focuses on customer value, construction and design efficiencies, as well as improved process flow and a minimization of waste. It is these principles that Gord is mindful of when designing any new residential project.

Gord has spent time getting builders like Homes by Dream up and running by helping set up design software and procedures as well as providing several new house models with everything from cozy starter homes to move up models and Estate homes. 

Inertia’s commitment to urbanization through bold and striking architecture is what made Gord most excited about joining the Inertia team.

Welcome Gord!
