Code & Compliance
Built to the IRC R310 emergency escape rule
Every basement sleeping room in Denver — and every habitable basement space — needs a code-sized emergency escape and rescue opening. The City and County of Denver, Jefferson, Arapahoe, Adams, Douglas, and Broomfield counties all enforce the same IRC R310 standard: a 5.7 sq ft net clear opening, a 44-inch maximum sill height, and a properly drained window well at least 36 inches deep.
We pull the permits, draft the engineered header detail, and walk the inspection on every project. Read the full Denver egress code requirements, the emergency escape rule, and what makes a basement bedroom legal — all written for Denver homeowners by our basement egress specialists.
Code-compliant openings
5.7 sq ft net clear opening, 24" min height, 20" min width, 44" max sill — sized correctly the first time.
Emergency escape sizing
Casement windows almost always hit code in a standard rough opening; sliders and hoppers usually need oversizing.
Drainage & freeze-thaw
Deep gravel base, filter fabric, and a perimeter-drain or daylighted tie-in built for Front Range clay.
Quick code questions
Yes — every Denver-area jurisdiction requires a building permit for any new opening cut into a foundation wall. Egress Denver pulls the permit and supplies the engineered header letter when the jurisdiction asks.

Denver egress window questions, answered.
