Basement Egress Window Requirements in Manitoba
What counts as an egress window in Manitoba, when the City of Winnipeg wants a permit, what the work typically costs, and how to plan it into a basement renovation.

Basement bedrooms are the reason most homeowners start googling egress windows. The moment a lower-level room is called a bedroom, it needs a second way out, and in Manitoba that window has real size, height, and well requirements attached. The good news: the rules are straightforward, the work is routine for any competent renovation crew, and planning it early is what keeps the budget sane.
This guide covers what an egress window actually is, the numbers Manitoba inspectors work with, when a permit is required, and what the work typically costs in a Winnipeg home. As always on this site, dollar figures are research ranges to plan with, not bids, and code details should be confirmed against the City of Winnipeg’s current requirements before you commit to a design.
What an egress window is for
An egress window is an emergency exit. Building codes treat below-grade bedrooms differently from other rooms because a basement fire or furnace problem can block the stairs, the only route an unfinished basement usually offers. The window gives the room a second escape path and gives firefighters a second way in.
The trigger in Manitoba, as in most of Canada, is the word bedroom. A den, an office, or a TV room generally does not require egress sizing. The moment the room is a bedroom, on the plans or in a listing, it does. This is also why we tell clients to be honest with themselves about what a lower-level room will be in five years. If the spare basement room is going to sleep a teenager or a visiting parent, plan the egress window now, at the same time as the rest of the renovation, when the walls are already open.
The numbers inspectors work with
Manitoba’s code requirements for egress follow the national pattern, and the numbers below are the planning figures we work from on Winnipeg projects:
| Requirement | Planning figure |
|---|---|
| Minimum openable area | 0.35 square metres (about 5.4 square feet) |
| Minimum opening dimension | 380 mm (about 15 inches) in each direction |
| Maximum sill height from floor | roughly 1.5 m so it can be reached and opened |
| Window well clearance | enough depth to climb out, typically 760 mm+ |
Two practical notes sit behind those numbers. First, the window has to open without keys, tools, or special knowledge, which rules out a lot of decorative hardware. Second, if the window is below grade, the well it opens into is part of the system. A window that meets every dimension but opens into a cramped, debris-filled well does not count as a usable exit.
Exact dimensions and exceptions, including rules for windows installed before current code, are the kind of detail the City of Winnipeg confirms at permit review. We design to the current standard and let the inspection confirm it.
Permits: when the City wants to know
Cutting an opening in a foundation wall is structural work. In Winnipeg that means a building permit, drawings or at minimum a scope sketch showing the opening and how the loads above it are carried, and inspections at the rough-in and completion stages. If the project also adds a bedroom as part of a legal secondary suite, the conversation gets bigger: development permit, fire separation, a second exit for the suite.
The permit is not a tax on enthusiasm; it is what protects you at resale. An unpermitted bedroom in a listing is a classic problem a buyer’s inspector finds, and it is much cheaper to paper the work correctly the first time. If you are weighing the permit question as part of a bigger lower-level plan, our basement renovation guide for Winnipeg walks the whole permit and sequencing picture.
What the work typically costs
For a standard Winnipeg bungalow or post-war home where the existing basement window is too small, cutting a new code-sized opening with a concrete saw, installing the window, forming the well, and restoring the interior and exterior finishes typically lands in the $1,500 to $3,000 per window band, well included. Treat that as a research range, not a bid.
Costs move for predictable reasons: thicker or reinforced foundations, deeply buried windows that need a bigger well and a ladder step, interior obstructions like furnaces or ducts that force the opening to relocate, and exterior grading or downspout work that should happen anyway so the new well does not become a pond. Winnipeg clay soils make that last point real; a well that traps spring melt against the foundation is a water problem waiting for April.
The winter angle most guides skip
Window wells in Manitoba are weather equipment. Snow goes in the well all winter, and spring melt sits there until it drains or finds a crack. Plan the well with drainage in mind: clear granular base under the well, a positive slope away from the window, downspouts discharging well past it, and if you use a clear well cover, one that can be lifted from inside without tools, because a cover that keeps snow out also has to let a person out.
Inside, choose window treatments that respect the exit. Heavy drapery or furniture parked in front of an egress window defeats the point. We plan bedrooms so the window keeps clear approach space and uses simple roller or panel treatments that will not tangle an escape.
Planning it into the renovation
Sequence matters more than difficulty. The egress cut is fastest when the basement is already partially opened up, the exterior grade is accessible for the well, and interior finish work has not reached the wall in question. On our projects, that usually means the window decision is made during design, not during framing. Build coordination on our basement work is with Task Reno, so the cut, the structure, the well, and the inspection happen in one planned sequence rather than as a surprise mid-project.
If you are mapping out a lower level that will someday count bedrooms, or you just want more daylight in a dark basement and want to know whether the opening can be enlarged while the crew is there, our interior design services in Winnipeg cover the planning side and the Winnipeg bungalow renovation guide covers the house-type realities. Bring us the room and we will tell you honestly what it needs to earn the name on the door.
