Finishing a basement in North Atlanta costs $25–$50+ per square foot in 2026, with the average project in Milton, Alpharetta, and Roswell running $30,000–$75,000 depending on size, current condition, and features. A finished basement typically recovers 70–80% of its cost at resale.
What qualifies as “finished”
Georgia code requires 7-ft ceilings (6′8″ under beams/ductwork), proper HVAC, fully finished walls and ceilings, code-compliant electrical, and adequate lighting. Bedrooms need egress windows (min 5.7 sq ft opening). “Finishing” converts raw space; “remodeling” reconfigures an already-finished basement; “renovating” updates existing finishes.
Cost by size
| Basement size | Cost range | Best for |
|---|---|---|
| Small (500 sq ft) | $12,500–$25,000 | Single-purpose room |
| Medium (1,000 sq ft) | $25,000–$50,000 | Multi-purpose space |
| Large (2,000 sq ft) | $50,000–$100,000 | Full apartment-style layout |
By finish level: unfinished→finished $30–$100/sq ft; partially finished→finished $7–$23/sq ft; remodeling an existing finished basement $4,000–$45,000+. Permits run $1,200–$2,000 and labor is about 40% of the total.
