Garage Finishing Cost: Per Square Foot in 2026
Estimate garage finishing cost per square foot — with the free drywall calculator.
A finished garage becomes a workshop, gym or bonus room instead of a storage cave. The drywall, floor and insulation add up fast. Here's the real 2026 cost.
THE SHORT ANSWER
The short answer
Garage finishing runs $15–$30 per sq ft in 2026 (typical project $7,000–$30,000). Drywall runs $2–$4 per sq ft; the floor coating $3–$7; insulation $1–$3. Simple updates cost less; full conversions with heat and AC cost more.
What it costs
A basic garage finish runs $7,000–$15,000. A full conversion with insulation, heat and AC runs $20,000–$30,000+. Drywall runs $2–$4 per sq ft; epoxy floor $3–$7; insulation $1–$3. The garage door, electrical and ceiling add the rest.
- Basic finish: $7,000–$15,000
- Full conversion: $20,000–$30,000+
- Drywall: $2–$4 per sq ft
- Epoxy floor: $3–$7 per sq ft
Basic vs full conversion
A basic finish covers drywall, paint and the floor — a clean workshop or gym. A full conversion adds insulation, heating/cooling, electrical circuits and lighting — a real habitable room. The gap between the two is $10,000–$20,000.
