Egress Windows Built for Littleton Basements
A basement bedroom, a home gym or a quiet office all start with the same question: can someone get out of that room quickly if there is a fire? Littleton’s residential requirements say basements in dwelling units and every sleeping room below the fourth story need at least one emergency escape opening. A properly sized egress window answers that question and lets in the kind of daylight a small hopper window never could.
Window choices include sliders, casements and European Tilt and Turn units, which open inward like a door or tilt at the top for ventilation.
Local know-how
Mid-Century Growth Along the South Platte
Littleton is one of the older communities in the south metro. It incorporated in 1890, sits along the South Platte River and serves as the Arapahoe County seat, with small pieces of the city reaching into Jefferson and Douglas counties. Its population jumped from about 3,400 in 1950 to nearly 13,700 by 1960, fueled by its closeness to Denver and the Martin Marietta facilities, so many neighborhoods took shape during those mid-century decades.
If your basement has only small windows set high on the wall, turning it into a bedroom usually means cutting a larger opening and digging a new well. One Littleton detail is easy to miss: the City measures the 44-inch maximum sill height from the interior finished floor. We set the window based on where your finished floor will be, not the bare slab, so the opening still passes after carpet or a subfloor goes in.

Permits Through Littleton's Building Division
Littleton’s Building Division reviews residential work under the 2024 International Residential Code, and required documents are uploaded through the City’s eTRAKiT portal. For any alteration to a foundation, the City asks for a drawing stamped by a Colorado-licensed Professional Engineer, and the Engineer of Record or a representative must inspect the work and verify it to the Building Division before final approval. That lines up with how we already work. Every Denver Egress Window job includes a third-party structural engineering detail, an inspection by a certified structural engineering firm and an approval letter, and we pull the building permit ourselves.

Egress windows in Littleton: FAQ
Is the 44-inch sill height measured from the slab or the finished floor in Littleton?
Littleton measures it from the interior finished floor. If you plan to add a subfloor, padding or tile later, that height matters. During the estimate we ask about your finish plans and set the window so the bottom of the clear opening stays within 44 inches of the floor you will actually walk on.
What does an egress window cost in Littleton?
The final number depends on your foundation wall, the window style, the well, access to the work area and what the jurisdiction requires.
My Littleton home is older. Can you still cut a new opening?
In most cases, yes. Littleton also requires a PE-stamped drawing for foundation alterations, so engineering review is part of the permit either way.
