What Does Basement Finishing Cost in Douglas County?

Basement finishing costs in Douglas County typically range from $25,000 to $75,000 or more, depending on the size of your basement and the level of finish you choose. On a per-square-foot basis, expect to pay:

  • Basic finish: $25-35 per square foot
  • Mid-range finish: $35-50 per square foot
  • High-end finish: $50-75+ per square foot

Factors That Affect Basement Finishing Costs

1. Basement Size

Larger basements cost more overall but may have a lower per-square-foot cost due to economies of scale. A 500 sq ft basement might cost $35/sf while a 1,500 sq ft basement might be $30/sf.

2. Bathroom Addition

Adding a bathroom significantly increases costs but also adds the most value. Expect to add:

  • Half bath: $5,000-10,000
  • Three-quarter bath: $8,000-15,000
  • Full bath: $12,000-25,000

3. Egress Windows

Required for legal bedrooms, egress windows typically cost $3,000-7,000 each installed, including foundation cutting and window well.

4. Ceiling Height

Basements with lower ceilings may require dropped ceilings or creative solutions, which can affect costs. The minimum ceiling height for finished space is 7 feet (or 6'8" under ducts and beams).

5. Existing Conditions

Moisture issues, insufficient drainage, or structural concerns must be addressed before finishing, adding to overall costs.

6. Finish Level

Material choices significantly impact costs:

  • Flooring: Carpet ($3-5/sf) vs. luxury vinyl ($5-8/sf) vs. engineered hardwood ($8-15/sf)
  • Trim and doors: Basic painted ($) vs. stained wood ($$$)
  • Ceilings: Drywall ($) vs. coffered/tray ($$$$)
