We talk a lot about egress windows, but many homeowners are not fully clear on what they are or why they matter.
If you have a basement in Muskego or the surrounding areas, understanding egress windows is important for both safety and code compliance.
What Is an Egress Window?
“Egress” simply means a way to exit.
An egress window is a window designed to provide a safe escape route from your basement or lower level in case of an emergency. It also allows emergency responders to enter if needed.
These are not standard basement windows. They must meet specific size and placement requirements to qualify.
Egress Window Requirements
To meet code, egress windows must follow strict guidelines:
Minimum opening width of 20 inches
Minimum opening height of 24 inches
Minimum opening area of 5.0 square feet (first floor) or 5.7 square feet (basement)
Maximum sill height of 44 inches from the floor
All of these requirements must be met for the window to be considered code-compliant.
What Does the Law Require?
According to the International Residential Code, any habitable basement must have at least one emergency escape and rescue opening.
In simple terms, if you are using your basement as living space, you need an egress window.
This applies to:
Bedrooms
Family rooms
Offices or dens
Finished basements
This requirement is enforced across Wisconsin and helps ensure your home is safe during a fire or other emergency.
Why Egress Windows Are Worth It
Natural light
Egress windows bring in significantly more natural light, making basements feel brighter and more comfortable.
Lower energy use
More daylight means less need for artificial lighting. Modern egress windows are also well insulated, which helps regulate temperature.
Increased home value
Homes in Muskego and nearby areas benefit from finished basements that meet code. Egress windows make that possible and more appealing to buyers.
Safety for your family
This is the most important reason. Egress windows provide a reliable escape route and allow emergency crews to enter quickly if needed.
