Basement finishing is priced per square foot ($25–$60/sq ft) — a 1,000 sq ft basement costs roughly double a 500 sq ft space.
Adding a basement bathroom adds $8,000–$15,000 and often requires an ejector pump if the drain is below the sewer line.
Building code requires an egress window in any basement bedroom for emergency escape. Installation costs $2,500–$5,000 per window including the window well.
Basements must be dry before finishing — waterproofing, drainage systems, or dehumidification may be needed, adding $2,000–$10,000.
Drop ceilings ($3–$6/sq ft) are cheapest and provide access to pipes/wires. Drywall ceilings ($4–$8/sq ft) look better but make future access harder.
The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
Budget $184–$920 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Summer is actually a great time for interior work since you're already running AC. Contractors may have more availability as exterior projects slow down in peak heat.
