A basement bedroom needs a code-sized egress window: at least 5.7 sq ft net clear, 24 in. clear height, 20 in. clear width, and a sill no higher than 44 in. Egress rules come from your city's adopted residential code (IRC R310 in 2021-code cities, R319 in 2024-code cities). Check with your building department. We set up the job across the Denver metro, and our local installer does the work.

Need a permit?
Basement bedrooms generally need an escape opening. Egress rules come from your city's adopted residential code (IRC R310 in 2021-code cities, R319 in 2024-code cities). Check with your building department (ICC; Arapahoe summary). In Denver, new egress windows need a permit (Denver CPD).
