Permission first. Construction second.

Zoning Bylaw 21-8724 defines attached suites and garage suites and sets site-specific requirements. The right answer still depends on your property and the proposed dwelling form.

Short answer

Zoning Bylaw 21-8724 defines attached suites and garage suites and sets site-specific requirements.

What local rules actually say

The published bylaw defines a secondary suite as accessory to an owner-occupied single-family dwelling. It recognizes both attached suites and garage suites. Section 8.7 states one suite per site, minimum 464.5 m² site, a maximum of 40% of the main dwelling floor area or 75 m² (whichever is less), and extra parking; verify the property zoning and any later amendments before applying these thresholds.

Important exceptions and the next step

A garage suite needs separate access and must meet required side/rear separations. Confirm current consolidated regulations with the Portage la Prairie Planning District before preparing plans.

How to verify an individual property

  1. Look up the legal property address and zone on the official Portage la Prairie zoning map.
  2. Confirm the proposed dwelling type: internal suite, addition, detached garden home or multiplex; these can follow different rules.
  3. Verify zone exceptions, lot size, servicing, hazard/heritage limits, any registered restrictions and the current amending bylaws.
  4. Ask the local planning/building office for the required written zoning confirmation and building permits before commissioning construction.
