Winnipeg’s secondary-suite guidance points to separate development and building permit review, as well as technical checks for fire separation, egress, services, and alarms. Its containment bulletin is specifically for attached secondary suites in a single detached dwelling. Use the City’s current requirements for the proposed configuration; the bulletin does not establish a Manitoba-wide design rule.
Separate the permit stages
The City says a development permit and a building permit are needed before a secondary suite is built. The building-permit application may be submitted after the development-permit application is confirmed complete for concurrent review, or after development-permit approval for sequential review. The City’s secondary-suite page also says separate electrical and plumbing permits are required.
Confirm the application route and current forms on Winnipeg’s secondary-suites page. The City notes that zoning and building-code review answer different questions; a permit checklist or a submitted drawing does not establish that a project is approved.
Show the attached-suite relationship on the plans
Winnipeg’s Information Bulletin 2021-006-B says an attached suite must be suitably separated from the principal dwelling and common spaces. It describes common spaces as areas that may include laundry, storage, building services, and egress areas. The bulletin says common spaces must be accessible through common hallways, stairs, or other shared means of egress; a common space cannot be accessible only through one of the suites.
The bulletin asks that building plans identify common spaces and clearly show building-service locations. It also treats some rooms with shared or out-of-suite equipment as common service rooms; the examples include shared hot-water equipment, ventilation equipment, heating equipment, and electrical service. The bulletin calls for smoke and sound separation and access through a common area or public corridor for a qualifying common service room. Ask the City reviewer how the bulletin applies to the proposed plans.
Winnipeg’s general secondary-suite page lists exits, smoke-tight barriers, window egress, fire protection, alarms, sound control, heating and ventilation, water, electrical systems, and utility access among the technical topics for review. That topic list is not exhaustive and does not supply a project-specific design.
Confirm the current code and inspection path
Before filing, identify whether the suite is attached or detached, gather the permit history and existing plans, and ask which code edition and review information apply. For a safety-related question such as separation, egress, or shared service access, use the current City bulletin and the building official’s interpretation. This guide summarizes the City’s published review checkpoints; it does not establish that a suite complies or may be occupied.
