What a Garage Build Cost Estimate Covers
A garage build cost estimate breaks down every component of a new detached garage — foundation, framing, roofing, siding, and doors — into a detailed, line-item budget sized to your desired car capacity and finish level. This covers a from-scratch, site-built detached garage rather than a prefab kit.
Estimate Florida Consulting provides detailed garage build estimates for homeowners and general contractors statewide, coordinated closely with our Menards garage kit estimating and storage building estimating services for complete outbuilding scoping.
This guide breaks down 2026 Florida market rates for detached garages by size and finish level, an interactive cost calculator, and the Florida-specific factors — wind load, foundation, and permitting — that most affect your final number.
Basic Shell vs. Insulated & Finished Garage
A basic shell — slab, framing, siding, roof, and a garage door with no insulation or drywall — sits at the lower end of the cost range. Adding electrical, insulation, and finished walls pushes the project into the mid-range. A fully finished garage with climate control and interior finishes commands the highest cost per square foot.
1-Car Garage
Basic single-car detached garage construction.
2-Car Garage
Standard two-car detached garage, the most common configuration.
3-Car Garage
Larger three-car detached garage for additional vehicle or storage capacity.
Finished Interior
Insulation, drywall, and electrical for a finished garage interior.

Detached garages typically cost 10-20% more than attached garages due to standalone foundation and utility requirements.
Foundation Type
Site conditions and soil affect foundation type and cost.
Roof & Siding Match
Matching the home's existing roofline and siding adds cost compared to a simple standard garage design.

Extending electrical and any plumbing to a detached structure adds to project cost.
