Basement finishing in Lone Tree.

A lot of newer Lone Tree homes came with a big unfinished basement, often a walkout on the sloped side toward the bluffs. We turn it into a guest suite, gym, theater, or bar, with egress, radon, and the city permit handled.

What we see in Lone Tree basements

Lone Tree basements are big, dry, and waiting to be used.

Since Lone Tree was incorporated in 1996, builders sold a lot of homes with a full unfinished basement below. Down toward Bluffs Regional Park, where the bluffs top out around 6,200 feet elevation, many of these are walkouts. Here is what usually turns up.

The big unfinished walkout

On the sloped south and east sides of Lone Tree, near Happy Canyon Creek and the bluffs, a lot of homes have a walkout basement with real windows and a door to the yard. That daylight makes it one of the best rooms in the house once it is finished.

A legal bedroom needs egress

If you want the basement to have a real bedroom, it needs its own emergency escape (egress) window and well sized to current code. On a walkout that is often easy. We cut it, set the window, and get it inspected so the room counts.

Radon and the clay under the slab

Radon mitigation is common on the Front Range, so we plan for it. Lone Tree sits on expansive Denver Formation clay that swells when wet, so we detail the subfloor and moisture barrier right to keep the finished space dry.

Suite, gym, theater, or bar

These are big homes, so most Lone Tree basements become a mix: a guest suite, a gym, a home theater, and a wet bar. We plan the wet bar plumbing and the wiring for sound and screens before a single wall goes up.

Tall ceilings, done right

Newer basements have taller ceilings than old Denver homes, which is a gift. We keep that height by planning the soffits around the ductwork and beams instead of dropping the whole ceiling.

The permit and inspections

A basement finish needs a City of Lone Tree permit under Municipal Code Chapter 18, applied for through the Accela portal, with framing, electrical, plumbing, and final inspections. We pull it and run the schedule so it is legal and adds to your value.

Lone Tree basement questions

What homeowners ask us.

Do I need a permit to finish a basement in Lone Tree?
Yes. The City of Lone Tree lists basement finishes as work that needs a building permit under Municipal Code Chapter 18, applied for through the Accela portal and inspected. We pull the permit and schedule the framing, electrical, plumbing, and final inspections so the space is legal and adds to your home value. Confirm current fees with the city.
Can we add a legal bedroom in the basement?
Yes, and it is a common ask. A legal basement bedroom needs its own emergency escape (egress) window and well sized to current code. Many Lone Tree homes have walkout basements that make this easier. We handle the egress cut, the window, and the permit so the room counts as a real bedroom.
What about radon and moisture under the slab?
Radon mitigation is common on the Front Range, and we plan for it. Lone Tree sits on expansive Denver Formation clay that swells when wet, so we detail the subfloor, insulation, and moisture barrier correctly, especially on a walkout, so the finished space stays dry and comfortable.
What can we put in the basement?
Most Lone Tree basements become a guest suite, a gym, a home theater, a wet bar, or an office, or a mix. These are big newer homes, so there is room to do it right. We plan the layout, the wet bar plumbing, and the wiring for sound and screens up front.
Are you licensed and insured?
Yes. JAC Enterprise is licensed and insured. License and insurance details come with your written estimate.
