Garage Construction FAQ
How much does it cost to build a garage?
A detached garage typically runs $20,000–$50,000 by size (one to three cars) and finish. Adding electrical, plumbing, insulation, or a room above raises it. Our estimator ranges it by size.
Attached or detached garage, which costs more?
Attached garages can be cheaper by sharing a wall and utilities, but site and roofline tie-ins vary. Detached gives placement flexibility and easier future expansion. A GC prices your lot and goals.
Do I need a permit to build a garage?
Yes, a garage is a structure requiring permits for foundation, framing, and any electrical or plumbing, plus zoning and setback checks. A licensed GC handles the permitting and inspections.
