What Is an Egress Window Well?

An egress window well is an enlarged well that gives a person room to climb out of a basement window in an emergency — and gives firefighters a way in. The International Residential Code (IRC section R310) requires an emergency escape and rescue opening in every basement sleeping room and in habitable basement space.

What the Code Requires

  • Window opening of at least 5.7 square feet, minimum 24" high and 20" wide
  • Window sill no more than 44" above the finished floor
  • Well floor area of at least 9 square feet, projecting at least 36" from the foundation
  • A permanently attached ladder or steps if the well is deeper than 44"
  • Everything must open from inside without keys, tools, or special knowledge

Municipal inspectors across Cook, DuPage, Kane, Will, and Lake counties enforce these numbers. We build to them every day, so your basement passes the first time.

Why an Egress Well Is Worth It

A legal egress opening is first and foremost about getting your family out in a fire. But it also pays for itself: converting a basement room into a legal bedroom typically adds significant resale value, and a bright full-size window transforms a dark basement. Appraisers and buyers can only count a basement bedroom if it has compliant egress.

Built for Chicago-Area Foundations

We install rugged galvanized steel egress wells fitted to your foundation, tied in cleanly with grade and siding, with proper gravel drainage at the base so the well never holds water. Pair it with a code-compliant ladder and a lift-off Lexan cover and the whole assembly is safe, dry, and inspector-ready.

Questions answered

Frequently Asked Questions

Do I need an egress window for a basement bedroom in Illinois?

Yes. The IRC, adopted across Illinois municipalities, requires an emergency escape and rescue opening in every basement sleeping room.

How big does an egress window well need to be?

The well must give you at least 9 square feet of floor area and project at least 36 inches from the foundation, with a ladder if it's deeper than 44 inches.

Does an egress well need a cover?

Covers aren't required, but an open egress well collects water, snow, and debris — and is a fall hazard. Our covers lift off from inside without tools, so they keep the well dry without violating code.

Will this pass my village's inspection?

We build to current IRC egress requirements and have worked with inspectors across the Chicago suburbs since 2001.
