Rezoning and Multiplex Standards

Policy Objectives

  • Cap multiplex developments at 4 units on residential lots
  • Restore public consultation for larger developments
  • Ensure infrastructure supports density increases
  • Balance housing growth with neighborhood stability

As of January 2026, the Alberta Non-Partisan Association formally advocates for a standardized approach to municipal zoning that balances housing density with neighborhood stability. The NPA's primary objective is to ensure that blanket rezoning does not lead to over-densification of established residential areas.

Core Policy Positions

The NPA supports specific amendments to municipal bylaws across Alberta to address concerns about uncontrolled density increases:

Policy Element Implementation
Limit Multiplex Density Standardize residential zoning so maximum allowable units for multiplex development on single-family or small-scale residential lots is capped at 4 units
Restore Public Consultation Require individual public hearings for any residential development exceeding the 4-unit limit to ensure neighbors have a direct voice in community growth
Prioritize Infrastructure Ensure any increase in density is supported by pre-existing utility, parking, and traffic infrastructure

Case Study: Edmonton Zoning Bylaw 20001

The NPA cites Edmonton's Zoning Bylaw 20001 as a primary example of where reform is needed. Under the current bylaw, developers are permitted to build 8-plexes on mid-block residential lots without a site-specific rezoning application or public hearing.

Proposed Changes to Bylaw 20001

  • Unit Reduction: Lower the current "as-of-right" limit from 8 units down to a maximum of 4 units
  • Mid-Block Restrictions: Specifically target interior lots (mid-block) where the impact of an 8-unit building on adjacent single-family homes is most significant
  • Community Alignment: Bring the bylaw in line with approximately 70% of residents who expressed concern over the scale of 8-plex developments during recent city-wide consultations

Rationale

The NPA recognizes the need for increased housing supply in Alberta's growing municipalities. However, density increases must be implemented thoughtfully:

  • Infrastructure Capacity: Existing neighborhoods were designed for single-family density; doubling or tripling population without infrastructure upgrades creates service deficiencies
  • Neighborhood Character: Established communities have character and scale that residents chose when purchasing their homes
  • Democratic Input: Blanket rezoning removes residents' ability to participate in decisions affecting their immediate surroundings
  • Gradual Transition: A 4-unit cap still allows meaningful densification while preventing jarring transitions from single-family to large multi-unit buildings

This policy framework supports housing growth while preserving the community consultation processes that allow residents to shape their neighborhoods.
