From Concrete to Comfortable: The Real Number
Wondering what it really costs to finish your basement? Not sure if the number in your head matches what finishing a basement actually takes?
In this post, you’ll learn what a basement finish costs here in Highlands Ranch, what drives that number up or down, what you get at each finish level, and how long the work takes.
By the end, you’ll know how to budget for your basement finishing project with real numbers instead of a low-end ballpark you found on HomeAdvisor.
What Does It Cost to Finish a Basement?
Finishing a basement in the South Denver Metro has starting costs between $100,000 and $200,000. The per square foot costs start between $150 to $250+, depending on the layout, systems, and finish level.
Our recent basement finishes have averaged around $117,500.
Because we build the lower level from scratch, that price covers new framing, plumbing, electrical, HVAC, permits, inspections, and finishes, not a quick cosmetic refresh of a space that was already livable.
Each of our basement projects includes a bathroom.
Basement Finishing Costs By Finish Level
Most basement projects fall into one of three finish levels, and the level you choose is what sets your budget.
Pricing is always based on your specific design and features, not square footage alone, but the ranges below show where projects usually start.
| Finish level | Price | What it includes |
| Streamlined full finish | Starts around $100,000+ (~$150/sq ft) | A from-scratch layout with usable living space, standard finishes, a dedicated electrical subpanel, and the option to add a bathroom. |
| Fully custom-built | Starts around $150,000+ (~$200/sq ft) | A custom layout with egress windows, plumbing relocation, custom storage, upgraded finishes, and a bathroom with a higher level of finish. |
| High-end, feature-rich build | Starts around $200,000+ ($250+/sq ft) | Significant customization with detailed bathrooms, built-ins, entertainment areas, and upgraded systems like steam showers or whole-home water filtration. |
What Drives the Cost of a Basement Finish
The biggest cost driver is the finish level you want, not the square footage by itself.
Two basements of the same size can land at very different prices, because we price around your specific design and features.
For homeowners D&D Remodeling works with in Littleton and Centennial, these are the factors that move the number the most:
- How custom the layout is.
- Whether you add a bathroom, a kitchenette, or a wet bar.
- Whether plumbing and electrical have to be relocated from the builder’s rough-ins.
- The finish materials, from flooring to tile to cabinetry.
- Anything we uncover behind the walls once demolition starts.
- If we need to add code-compliant egress windows.
We don’t build budget, minimal-scope basements that just make the space usable.
We build full living spaces, so the price reflects a fully designed floor rather than the cheapest path to drywall.
When we do run into something unexpected, like a foundation crack or mold, we have a built-in contingency to handle the problems we typically see, and we talk you through any fix before we move ahead.
Permits, Code, and the Systems Behind the Walls
A basement finish is essentially building a new floor inside your home, so the code work matters as much as the finishes.
During the design phase, we coordinate electrical, plumbing, HVAC, and egress together so everything works as one system.
We’re a Colorado Class C residential contractor, fully licensed and insured for the work.
A few things almost every basement needs:
- A dedicated electrical subpanel.
- Egress windows, which our more custom basement builds include.
- Plumbing relocation, because builder rough-ins are rarely in the right spot.
We always pull permits for basement finishes. It isn’t negotiable.
What a Finished Basement Is Actually Worth
A lot of cost guides sell basements on a resale ROI percentage, and that’s not how we look at it.
We only take on projects for homeowners across the South Denver Metro who want to live in their home, not flip it.
The real return is a floor that finally does what your house couldn’t before, whether that’s a guest suite, a lounge, a home office, a gym, or all of them at once.
How Long Does a Basement Finish Take?
Timeline tracks closely with finish level, since a more custom build means more systems and selections to coordinate.
- A streamlined full finish usually takes about 6 to 8 weeks.
- A fully custom build runs closer to 8 to 10 weeks.
- A high-end, feature-rich build can take 8 to 12+ weeks.
We put a strong emphasis on the design phase up front, where we dial in the layout, selections, and scope, and then lock in your final price before construction starts.
One lead stays on your project from demo to final walkthrough, so the schedule and the details stay consistent the whole way through.
