A basic 12x12 foot single-car garage may cost $15,000–$25,000, while larger or custom designs can exceed $50,000. Key elements include foundation type, roofing material, insulation, windows, and door choices. Compliance with zoning laws and building permits also affects final cost.
Typical Cost Breakdown per Square Foot
On average, building an additional garage ranges from $250 to $400 per square foot. This includes framing, exterior finishes, electrical and plumbing (if integrated), insulation, and roofing.
