The average cost to finish a basement is about $32,000, though the price can range from $2,800 to $100,000 or more, depending on the materials, permits, appliances and labor required.
Finishing a basement may increase your home’s value. You can expect to recoup about 70% of what you spent if you sell your home . Your home’s specific increase in value depends on your location, how your home compares to other homes for sale in your area, and how much work you’ve had done.
Here's what to know about the factors that contribute to basement finishing costs and whether the project is worth it for your home.
Why finishing a basement can be worth it
- Value. Finishing a basement may add as much as 10% to your home’s value, with an average return on investment of about 70%. Your return on investment will depend on your home’s location and condition, as well as the features of your basement. Home buyers may consider a finished basement a desirable feature.
- Energy bills. With an unfinished basement, your home’s HVAC system needs to work harder to control the temperature in your entire home. Finishing the basement insulates it from extreme temperatures, potentially lowering your heating and cooling costs.
- Rental income. If your basement space meets local building codes, renting it out might offset your renovation costs, bringing you a larger return on your investment.
- Increased space. Finishing your basement can increase your home's usable square footage. You can use that space for an extra bedroom, den, playroom, home theater, kitchen, bathroom, music studio, gym, or any other type of room that suits your lifestyle.
- Noise control. A finished basement can take noisy activities, such as loud music practice, parties or children's play, away from the home’s main living space.
- Protection. During severe weather or natural disasters, the basement may be the safest area of the house. A finished basement allows you to enjoy that shelter in a comfortable living space.
Why finishing a basement may not be worth it
- Cost. Finishing a basement is a sizable expense, and you may need financing to complete your project.
- Value. You probably won’t recoup 100% of your expenses, unless you plan to rent out the space for many years.
- Property taxes. Finishing your basement may increase your property’s taxable value, raising your property taxes. To find out whether and how much your property taxes will increase if you finish your basement, contact your town or city’s municipal office.
- Building codes. Permit(s) and municipal inspections will likely be necessary to ensure your basement meets safety regulations, and can come at an added cost.
- Moisture.
- Lighting may not be optimal. Basements are often dark spaces, so you may need to purchase and install extra windows or lighting fixtures to make it a comfortable space.
- Electrical and plumbing access. Drywalling your basement may make electrical and plumbing lines hard to reach. If you don’t install removable access panels, you may need to cut walls open to complete future repairs.

| Plumbing | About $45 to $200 per hour, depending on the extent of the plumbing work needed. |
| Framing | $700 to $1,800 ($7 to $16 per linear foot) on average, not including drywall or insulation. |

Many Reddit users who have finished their basements expressed satisfaction with the project, noting that they enjoy the extra living space. Returns on investment varied widely, with one user noting that their home value increased $95,000 after investing $35,000 in the project, and others saying their home value didn’t increase much. Users often suggest doing this project for the enjoyment of the home rather than investment, and one user recommended testing for radon before getting started.
