Finishing a basement in Colorado typically costs between $50,000 and $95,000.
That’s based on a range of $50 to $95 per square foot, and most basements fall between 800 to 1,200 square feet.
But that’s only part of the story.
Because what you actually pay depends on something much more important than square footage: what your basement is supposed to do.
Is it a simple hangout space? A quiet guest suite? A second family room with a bathroom and built-in storage? That difference—not the size—is what really drives cost.
Let’s walk through what makes basement remodels more (or less) expensive, and what you should be thinking about if you want to get it done right.
1. The Simpler the Layout, the Lower the Price
Open spaces cost less. Breaking that space into bedrooms, bathrooms, offices, and bars? That’s where it adds up.
- A basic open-plan rec room is on the lower end
- Adding framed walls, a bathroom, or a laundry area bumps up the budget
- More rooms = more wiring, lighting, outlets, flooring transitions, and permits
A large, simple layout is more affordable than a smaller basement with complex framing and plumbing. Ironically, it’s not always about square footage. It’s about how many layers are involved.
What to consider:
Start with a list—not just of what you want the space to be, but how you’ll use it weekly. What gets the most foot traffic? Do you really need three rooms, or one really functional one?
2. The Finish Level Matters More Than You Think
A basement doesn’t have to look like your upstairs. But when it does, that’s where you see higher material costs.
Here’s how the levels usually shake out:
Basic Finish
Painted drywall, carpet, or LVP flooring, can lights, and one big open room.
Typical cost: $50–$65 per sq. ft.
Mid-Level Finish
Separate rooms, bathroom, and moderate upgrades like tile or recessed lighting.
Typical cost: $65–$80 per sq. ft.
High-End Finish
Custom cabinetry, kitchenettes, luxury bath features, built-ins, and designer flooring.
Typical cost: $80–$95+ per sq. ft.
What to consider:
Don’t pay for a level of finish you don’t actually care about. If it’s a playroom for kids or a casual movie space, you probably don’t need high-end materials. But if this is your new guest suite, or do you plan to rent it short-term? The upgrade pays off.
3. Plumbing and Electrical Work Are Where Costs Sneak Up
Adding a bathroom is convenient. Adding a bar is fun. But both require plumbing, water lines, drains, outlets, and venting—and these are the parts most homeowners underestimate.
You might also need:
- Electrical panel upgrades if the system is maxed out
- A sump pump or drain tile system (if your basement is prone to water)
- Egress windows (required for basement bedrooms)
Plumbing is especially costly in basements where no rough-ins exist. That’s where concrete has to be cut, moved, and patched—often before anything even gets built.
What to consider:
You don’t need to avoid plumbing entirely, but weigh your priorities. Would a half bath do the trick instead of a full one? Is a mini fridge and built-in storage enough, or are you committed to a full wet bar?
4. Permits, Inspections, and Local Code Can Add Thousands
No one loves dealing with permits, but they’re required. And they cost time and money.
Every city in Colorado (including Greeley, Fort Collins, Loveland, and beyond) has different expectations, but here’s what most basements require:
- Framing, electrical, plumbing, and insulation inspections
- Fire blocking and egress verification
- Final walk-through for sign-off
Skipping this step? That’s how you end up with finished basements you can’t legally list as living space—or worse, safety issues that come back to bite you later.
What to consider:
Budget $1,000–$2,500 for permit costs, plans, and inspections. Make sure your contractor includes this in the proposal and takes care of the paperwork.
5. Moisture Matters—Even If You’ve Never Had a Leak
Even the driest basement needs to be treated with moisture in mind. Why?
Because finishing a basement traps what used to be an open-air space, without vapor barriers, insulation, and air flow, you run the risk of condensation, musty air, and mold behind your walls.
What to consider:
Ask about insulation types, rim joist sealing, and underlayment options. Even a simple dehumidifier or ventilation fan can extend the life of your remodel and improve comfort, especially in Colorado’s freeze-thaw cycles.
6. Add-ons Can Change Everything—For Better or Worse
We’ve seen homeowners spend an extra $20,000 on a basement bathroom they barely use, while skipping things like smart storage, better lighting, or noise insulation.
It’s not always about the biggest features—it’s about the right ones.
Here are some optional add-ons and what they typically cost:
| Feature | Cost Range |
| Bathroom | $8,000–$20,000 |
| Wet bar/kitchenette | $5,000–$15,000 |
| Egress window | $3,000–$7,000 |
| Built-ins or storage | $2,000–$6,000 |
| Media wall/fireplace | $4,000–$10,000 |
What to consider:
Add the features you’ll use often—and skip the ones that just “seem cool.” The best basements are the ones that feel like a natural extension of how you already live.
Final Thoughts: It’s About More Than Square Footage
You can’t price a basement remodel based on size alone. The right cost depends on what you want from the space, how your home is set up, and what features matter most to your family.
Done right, a finished basement can completely change how your home works—from giving your kids their own space to creating an income-generating guest suite.
So instead of asking “how big is it?”, ask this:
What should this space do for you?
Start there, and the cost will start to make a whole lot more sense.

FAQs
1. Do permit costs and requirements differ between Fort Collins, Greeley, and Loveland?
Absolutely. Each city has its own quirks:
- Fort Collins tends to be the most detailed—they’ll scrutinize insulation values and energy efficiency closely.
- Greeley focuses heavily on egress window specs and fire safety in basements.
- Loveland often requires radon mitigation plans upfront, even if not mandatory elsewhere.
- We’ve navigated these differences countless times and handle all permits for you. Budget $1,200–$2,500, depending on your city and project scope.
2. How does soil type affect basement costs in Windsor, Johnstown, or Berthoud?
These areas sit on heavy clay soil that expands when wet and shrinks when dry. It’s tough on foundations. If your home is in Windsor’s newer developments or Johnstown’s older neighborhoods, we might recommend:
- Extra structural reinforcement during framing.
- Improved drainage systems (like French drains) to prevent soil pressure cracks.
- Moisture barriers, even if you’ve never seen water.
- It’s a small upfront cost that saves headaches later, especially during Colorado’s freeze-thaw cycles.
3. Are radon concerns different in Timnath vs. Fort Collins basements?
Yes, but it’s a risk everywhere in Northern Colorado. Timnath’s newer builds often have rough-ins for radon systems, but older homes in Fort Collins or Greeley rarely do. We test every basement before finishing. Installation during a remodel costs $1,200–$2,500—far cheaper than retrofitting later. Don’t skip it; radon levels here are among the nation’s highest.
4. Will my Loveland basement need special moisture protection?
Loveland’s proximity to the foothills means higher spring runoff and water tables. Even basements that seem dry can develop hidden moisture behind walls. We always recommend:
- Sealing rim joists and foundation cracks.
- Adding vapor barriers beneath drywall.
- Installing a backup sump pump (critical during sudden summer storms).
- It’s not overkill—it’s insurance against Northern Colorado’s unpredictable weather.
5. Do ceiling height rules vary in Greeley vs. Windsor basements?
State code requires 7-foot minimum ceilings, but local enforcement differs:
- Greeley inspectors are strict about measuring around ductwork.
- Windsor often allows creative solutions like tray ceilings to meet code.
- Fort Collins may require extra clearance for HVAC access.
- We’ve worked in hundreds of basements across these cities and know how to maximize headroom while passing inspections.
6. What energy upgrades are required in Fort Collins basement remodels?
Fort Collins has some of Colorado’s strictest energy codes. Your basement will likely need:
- High R-value insulation (we recommend foam board for basements).
- Air-sealing at rim joists and penetrations.
- Energy-efficient lighting (LEDs are standard now).
- These aren’t just rules—they cut heating bills during our freezing winters. We’ll ensure your remodel meets every requirement.
7. How common are basement water issues in Berthoud or Johnstown?
More than you’d think. Even in drier areas like Berthoud, snowmelt and summer downpours can seep through foundations. In Johnstown, older homes often have outdated drainage. We always:
- Inspect exterior grading and downspouts.
- Check for cracks during demolition.
- Recommend sub-floor drainage if needed.
- Fixing moisture before finishing saves thousands later.
8. Can I add a bedroom to my Timnath basement? What’s required?
Yes, but egress windows are non-negotiable in Timnath, Windsor, and all your service areas. They must:
- Open wide enough for emergency escape.
- Sit no higher than 44″ from the floor.
- Include a window well (if below grade).
- Costs run $3,000–$7,000 per window. It’s a safety investment—and adds resale value if you ever list your home.
