Approx. how much does it cost to renovate an existing small basement egress window so that it could fit the legal standards in Winnipeg?

I need to reconstruct the window according to city of Winnipeg's standards, so that we can give it for rent.

The legal size for the basement window is 24"x24" (opening ) or 15"x36.2" (opening). We recommend double slider window for building code requirements.

Windows must furnish occupants with natural light, provide an exit in an emergency from the bedroom area and sup- ply natural ventilation.

Ability to open: Each bedroom must have at least one outside window. This window must be openable from the inside with- out the use of tools or special knowledge (except where a door provides direct access to the exterior).

Unobstructed area when open: The window must provide an unobstructed opening with a minimum area of 0.35 sq. m. (3.77 sq. ft.) with no dimension less than 380 mm (15 in.).

NOTE: Although the minimum dimensions required for height and width are 380 mm (15 in.), a window that is 380 mm by 380 mm (15 in. by 15 in.) would not comply with the minimum area requirements.

Window opening into a window-well: Where a window re- quired for a bedroom opens into a window-well, a clearance of at least 550 mm

(22 in.) must be provided in front of the window. Where the sash swings toward the window-well, the operation of the sash must not reduce the clearance in a manner that would restrict escape in an emergency.

The cost for the new window and foundation cut out is about $1500

Hi Sneha,

The link to Winnipeg bylaw is

You do have to remember that the sizes are inside clear space to escape and not the window size!!!

That means that the window size will be bigger, depends on the manufacturer.

You should try to use double slider lift out window so both sashes will be removable to maximize the open space.

Thank you Alex and Harry.

Alex, also, could you please tell me, does the 1500 include finishing the window on the inside (the room side) or will that cost me more money, besides the 1500?
