Egress Windows: What You Need to Know Before Installing One
Sep 11, 2025An egress window is a window large enough to allow someone to exit your home in case of emergency—or for rescue personnel to enter. Michigan law requires emergency escape and rescue openings in every sleeping room, habitable attic, and basement with bedrooms. They must meet certain size requirements.
Key Code Requirements in Michigan
Here are some code essentials for an egress window in Michigan:
-
A net clear opening of at least 5.7 square feet (for ground-floor or grade windows this drops to 5.0 sq.ft). The Great Egress Company USA
-
Clear opening dimensions at least 24″ high and 20″ wide. The Great Egress Company USA
-
Sill height no more than 44″ above finished floor. The Great Egress Company USA

If the window is below grade, there must be a window well (at least 9 sq.ft, minimum width and horizontal projection of 36″ each) and includes ladder or steps if the well depth exceeds 44″. The Great Egress Company USA
