Basement Finishing Littleton, CO
Most Littleton homes from the late 70s and early 80s came with unfinished basements. Forty-plus years later, they’re still unfinished. Arch Design & Build turns them into permitted, livable space — design, engineering, and construction under one contract
How Much Does Basement Finishing Cost in Littleton?
It depends on scope — and what’s already down there.
An open-plan family room with drywall, flooring, and lighting is a straightforward project. Add a bedroom, closet, and full bathroom, and you’re into plumbing rough-in work, egress windows, and a more involved permit process. Both are achievable. The scope drives the number.
One thing common in Littleton’s early-80s construction: basements with original plumbing rough-ins that weren’t designed for a modern bathroom layout. We assess the existing rough-in location and tell you upfront whether it works as-is or needs to be relocated — before a dollar is spent on design.

Littleton Permits for Basement Finishing
Do I need a permit to finish my basement in Littleton?
Yes. Framing new walls, adding electrical, running plumbing, and installing egress windows all require permits through the City of Littleton. Any room classified as a bedroom needs a code-compliant egress window — that goes through both building and zoning review.
We handle every application, every inspection, every sign-off. You don’t touch a form
Why Finish Now?
You’re already heating that basement. Finishing it adds genuine square footage — without the cost of an addition — and meaningfully increases your home’s appraised value. In Littleton’s market, that’s a return worth taking seriously

Frequently Asked Questions
How long does basement finishing take in Littleton?
A straightforward open-plan finish runs 5–7 weeks. Add a bedroom and bathroom and plan for 8–11 weeks. City of Littleton permit review is built into the schedule from day one.
My basement ceiling is low. Can it still be finished?
Colorado requires 7 feet of ceiling height in habitable rooms. We measure during the consultation and give you an honest answer — including whether a partial dig-out makes financial sense for your project.
Can I use the finished basement as a rental unit?
Possibly — but it requires specific egress, a certificate of occupancy, and compliance with Littleton’s requirements for secondary units. We’ll tell you upfront what’s required and whether your basement qualifies.
