Cost to Build a Detached Garage in Florida
Professional cost estimates for detached garage construction — 1-car to 3-car, wood-frame or CBS, sized to your lot.
What It Costs to Build a Detached Garage in Florida
A detached garage is a full construction project in miniature — foundation, framing or block walls, roofing, and often electrical — and Florida's wind-load requirements apply just as they do to the main house.
Whether you're building a simple 1-car garage or a 3-car garage with a workshop bay, the estimate needs to account for foundation type, wall material (wood frame vs. CBS), roof structure, and any finished interior space like drywall, electrical, or a mini-split system.
We prepare line-item, bid-ready garage construction estimates covering the full scope — from slab to roof — priced to current Florida labor and material costs.
What Drives Garage Construction Costs
Wall Construction
CBS (concrete block) construction costs more than wood frame but matches most Florida homes.
Garage Size
1-car, 2-car, and 3-car garages scale roughly, but not exactly, linearly in cost.
Finished vs. Unfinished
Drywall, insulation, electrical, and flooring finish add significantly to a bare-shell garage.
Wind Load & Roof Structure
Garage roof framing must meet the same wind-load requirements as the main structure.
Permit & Setback Requirements
Detached structures must meet local setback rules and typically require a building permit.
Door & Opening Count
Number and size of garage door openings affects both material and structural cost.
Detached Garage Cost by Size
Ranges reflect typical Florida installed costs for a bare-shell to lightly finished detached garage. Final quotes depend on wall material and finish level.
| Garage Size | Typical Cost Range | Notes |
|---|---|---|
| 1-Car (12' x 20') | $18,000 – $32,000 | Bare shell to lightly finished |
| 2-Car (20' x 20') | $28,000 – $52,000 | Most common configuration |
| 2-Car with Workshop Bay (24' x 30') | $42,000 – $75,000 | Additional bay for storage or workshop |
| 3-Car (30' x 30') | $55,000 – $95,000 | CBS construction, finished interior |
