Escape Requirements
Why every Denver basement bedroom needs a second exit.
A basement fire fills the stairwell with smoke in under two minutes. The IRC's emergency escape rule exists for a reason — here's exactly how to meet it.

The IRC's emergency escape and rescue opening (EERO) requirement isn't paperwork. It's a fire safety rule written after decades of basement bedroom fatalities, and it applies to every sleeping room on every level of a Denver home built or remodeled under modern code.
The math is simple: smoke rises. A basement fire fills the only stairwell in the house with toxic smoke in well under two minutes. Without a second exit, occupants in basement bedrooms have nowhere to go. The egress opening — a code-sized window or walkout door — gives them a way out and gives firefighters a way in.
What "compliant" actually means
- 5.7 sq ft minimum net clear opening (5.0 sq ft at grade)
- Minimum 24" tall × 20" wide opening
- Sill no higher than 44" above the finished floor
- Operable from inside without a key, tool, or special knowledge
- Window well at least 36" deep with adequate horizontal clearance
- Permanent ladder if the well exceeds 44" deep
- Hard-wired interconnected smoke alarm in the bedroom
- Natural light = 8% of floor area; ventilation = 4% of floor area
Why the Denver context matters
Most basement bedrooms in Denver's older zip codes — 80207 (Park Hill), 80211 (Sunnyside, Berkeley), 80212 (Sloan's Lake), 80210 (Wash Park), 80218 (Capitol Hill), 80205 (Five Points/Whittier) — were finished long before modern egress was code. Adding an emergency escape opening is the single biggest safety upgrade you can make in those homes, and it's almost always the missing piece between an unfinished basement and a legal, sellable bedroom.
How we make a Denver basement compliant
We engineer every install to meet the spirit of the code, not just the letter. That means a code-sized casement window, a properly sized and drained well, mechanical anchoring to the foundation, and a final inspection with the city. For homes where a window isn't the right answer, a walkout basement door satisfies the same requirement with a true second exit.

FAQ
Emergency escape questions Denver homeowners ask.
Yes. Per the IRC adopted across Colorado, every sleeping room — basement, ground floor, or upstairs — needs an emergency escape and rescue opening (EERO) that opens directly to the outside. In a basement, that almost always means an egress window or walkout door.
