Is your basement just the place where boxes go to be forgotten? Are you wondering what it really costs to turn bare concrete and exposed floor joists into a room you actually want to spend time in?
Not sure where a basement build-out even starts?
In this post, you’ll learn what drives the cost of a basement build-out, the permits and building codes involved here in the Denver Metro Area, how our process works step by step, and what you can build in the new space.
By the end, you’ll know what to budget, what to expect, and how to plan a finished basement with confidence.
The Short Answer on a Basement Build Out
A basement build-out, also called basement finishing, is the process of turning an unfinished basement into a finished, usable living space, including framing, electrical work, plumbing fixtures, insulation, hanging drywall, flooring, and final finishes.
For homeowners across the Denver Metro Area, a 1,000-square-foot basement starts at about $57 per square foot, or $57,000 before upgrades.
Most projects take roughly 6 to 10 weeks, begin with a free design phase, and include the permits handled by us.
What Drives the Cost of a Basement Build Out
We don’t believe in throwing a national average at your project and calling it a quote.
We design before we price, so the number reflects your actual basement space and goals.
To give you a fair starting point, we use tiered per square foot rates that go down as your basement gets bigger, which is a simple economy of scale.
| Basement size | Starting rate |
|---|---|
| ~500 sq ft | ~$74 per sq ft |
| ~1,000 sq ft | ~$57 per sq ft |
| ~1,500 to 2,500 sq ft | $48 to $50 per sq ft |
Size and condition of your basement
Bigger basements cost more overall, but the cost per square foot usually drops as the usable square footage grows.
A complex or unusually shaped layout takes extra time and materials.
Older homes and tight access for moving materials into the basement can also increase the number.
The rooms and features you add
A wide-open rec room costs less than a remodeled basement packed with a bedroom, a bathroom, and a bar.
Here are the typical upgrades that add value to a basement remodel.
| Upgrade | Typical cost |
|---|---|
| Extra bedroom or office | ~$5,000 |
| Half bath | $8,000 to $10,000 |
| 3/4 bath | $12,700 to $15,500 |
| Full bath | $15,000 to $19,000 |
| Wet bar, small to large | $5,000 to $25,000 |
| Egress window | $2,600 to $5,600 |
The Cost Factors Beneath the Surface
Some of the biggest cost factors are the ones you never see once the project is done.
Getting these right is what keeps a finished basement healthy for the long haul.
This is also where building here is different from building anywhere else.
Moisture, Colorado clay soils, and radon
We treat moisture and the cost of basement waterproofing as required first steps, not optional add-ons.
That can mean grading soil away from the foundation, sealing the basement walls and concrete floor, improving drainage, and installing a sealed sump pump with drain tile to stop water intrusion and slab cracking.
Here in Denver, we also build around expansive clay soils and install a radon mitigation system as part of our standard structural work to achieve a radon-resistant finish.
Materials, comfort, and finishes
Your finishes account for a significant portion of the budget, and the range is wide.
Flooring runs from carpet at $3 to $10 per square foot up to tile at $15 to $25, with luxury vinyl plank at $7 to $9 and engineered wood at $6 to $12.
LVP over a leveled concrete floor runs about $14.50 per square foot installed.
For comfort and energy efficiency, these upgrades pull their weight:
- Upgraded foam insulation at about $1.60 per square foot.
- Soundproofing at about $3.13 per square foot.
- Heated flooring or a fireplace to hold the basement temperature through Denver winters.
Permits and Denver Building Codes
A basement build out, like any major remodeling project, needs permits, which you can learn how to pull, in the Denver Metro Area, and that trips a lot of homeowners up.
The good news is you don’t have to deal with it.
We manage the full permit and inspection process for your project from start to finish.
That includes the Town of Parker Building Division and South Metro Fire Rescue through eTRAKiT, Littleton’s eTRAKiT under the 2021 IRC, the Castle Pines Residential Basement Finish checklist, and Arvada’s Residential Interior permit under the 2018 building codes.
Those codes cover egress windows and their size requirements, fireblocking in the framing, and smoke detectors.
Codes also set minimum ceiling heights, which matters if your ceiling joists sit low.
How the Basement Build Out Process Works, Step by Step
A basement remodel involves many moving parts, and the order matters.
Doing steps out of sequence is how projects get expensive and slow down.
Here is how we keep the entire process organized.
Planning and design before the build
Our turn-key process, mapped out step by step, starts long before anyone picks up a hammer.
- Submit the contact form to tell us about your project.
- Meet for a phone consultation, then an on-site consultation with measurements.
- Review and approve your floor plan design, which we usually draft in about two days.
- Visit our partnered showroom to pick your finishes.
The design phase is free, and we plan a 10 to 15 percent contingency into the budget for any moisture or structural surprises.
The build sequence, in order
Once your plan is approved and permits are in hand, construction follows a clear path.
- Frame the interior walls, including the top and bottom plates, and rough in plumbing, electrical, and mechanical systems through drilled holes in the framing.
- Install proper insulation, the vapor barrier, and all the drywall.
- Add basement floor finishes and the ceiling systems.
- Paint, then set cabinets, doors, and finishing touches.
- Pass final inspections and walk the finished space together.
Is a Basement Build-Out a Good Investment?
A basement build-out is one of the most budget-friendly ways to add living space, because the foundation, basement walls, and concrete floor are already in place.
Appraisers usually value below-grade space at about half the rate of above-grade space, so finishing it can significantly increase your home’s resale value and usable square footage.
Choosing finishes with broad appeal is what adds the most value when it comes time to sell.
A walkout basement brings in more natural light, can have a separate entrance, and may work as a rental or guest suite.
The bigger payoff is lifestyle, since you get more space out of the home you already own instead of moving.
What You Can Build Down There
Once the space is finished, what goes in your new space is up to you.
For homeowners we work with in Littleton’s older homes, this is often where extra living space finally catches up to how the family actually lives.
Popular ways to create a finished basement you’ll use include:
- Home theaters, home gyms, and game or entertainment rooms.
- Wet bars, kitchens, and wine or cigar rooms.
- Extra bedrooms, luxury bathrooms, and guest suites.
- Hidden rooms, like a bookcase that swings open to a quiet retreat.
- Steam rooms, golf simulators, custom carpentry, fireplaces, and open stairwells.
Across our projects, you’ll see recurring touches like LVP flooring, recessed lighting, and open-concept layouts that make the whole level feel like part of the house.
