Any “finished basement” has been upgraded from storage space to a livable area on par with the rest of the house. Unlike an unfinished basement, a finished basement should be fully insulated, waterproof, and just as comfortable and functional as the home’s main floors.

Heating and Cooling Systems

Finished basements have access to HVAC systems, while unfinished basements have inferior or nonexistent climate control. Proper heating and air conditioning make a finished basement comfortable and prevent problems that are common in unfinished basements, such as dampness or excessive cold.

Walls and Flooring

Finished basements mirror the aesthetics of the rest of the house and have fully finished walls complete with drywall, insulation, and paint or wallpaper. That means no exposed studs, pipes, or electrical systems, which are visible in most unfinished basements. 

Flooring in a finished basement is a step up from an unfinished basement’s concrete flooring. A finished basement’s flooring could be carpet, tile, vinyl planks, or hardwood.


A finished basement should have a well-constructed and well-lit staircase, often with handrails, that connects the main floor to the basement. Egress windows or walk-out entrances are common in finished basements and may be required by local building codes, particularly if the basement includes an extra bedroom. A finished basement cannot be included in a home’s total square footage without these features.

Other Requirements

You must ensure that a finished basement meets all federal, state, and local requirements if you want to advertise a fully finished basement when you sell your house. A licensed real estate agent, home inspector, or contractor can walk you through the upgrades required to transform an unfinished or partially finished basement into a livable space. Contact your local building department for more information.

Building codes spell out requirements for room dimensions, lighting, ventilation, and insulation. Virginia, for example, requires ceilings that are at least seven feet above the finished floor, rooms that are at least 70 square feet, and rooms that have at least one exit. Consider that it could be a significant investment to dig out a basement large enough to have seven-foot ceilings or to excavate to install an exterior door or window in an older home.

Advantages and Disadvantages of Finishing Your Basement

Upgrading your basement space offers several immediate and long-term benefits. 

  • Comfort: Upgrades make for a more comfortable, versatile, and usable living area than an unfinished or partially finished basement.
  • Extra space: Finishing your basement adds square footage for a home office, second living room, spare bedroom, home theater, or game room.
  • Resale value: A finished basement increases your home’s value and may make it more attractive to potential buyers.

Planning a finished basement is no small task, and it doesn’t make sense for everyone. Consider the potential drawbacks before splurging on this home improvement project. For instance:

  • Housing market: If buyers in your area do not care about having a finished basement, you may not see a good return on investment.
  • Maintenance: Increasing the finished square footage and your home’s living area also means more cleaning and maintenance.
  • Up-front cost: Basement renovations can be expensive and time-consuming, especially in rainy climates or older homes.

Potential Costs and Added Value

The cost to finish your basement will vary depending on the home’s age, the basement’s condition, and your design choices. To give you an idea of what to expect, here are a few potential costs:

  • Asbestos removal: $1,170–$3,050
  • Building permits: $1,200–$2,000
  • Ceiling: $1,610
  • Exterior door: $2,500–$10,000
  • Drywall: $1,750
  • Flooring: $1,500–$4,500
  • Framing: $1,800
  • Electrical wiring: $4,000
  • Insulation: $700–$2,000
  • Interior doors: $360–$1,160 each
  • Lighting fixtures: $360 each
  • Mold removal: $2,225
  • Paint: $1,800
  • Repairs: $2,160–$7,735
  • Sump pump: $575
  • Waterproofing: $4,400
  • Windows: $200–$950 each

Cost data in this article was sourced from Angi.

It costs $30–$50 per square foot to finish a basement, according to Rocket Homes, which will amount to a return on investment as high as 75%. This works out to $18,000–$30,000 for a 600-square-foot space with up to $13,500–$22,500 of value added.

Consult a local real estate agent or property appraiser to determine whether finishing your basement is worth the investment. They can provide insight into how much value a finished basement might add to your area. Weigh the cost of hiring a contractor for the entire remodel against tackling a few DIY basement projects.

Our Conclusion

The additional space a finished basement offers may be worth the investment for your family, even if the space doesn’t always pay for itself in terms of resale value. Having a finished basement may give your home an edge when you’re ready to sell, but it’s important to research the housing market and building codes in your area before making a decision.
