A single car garage typically ranges from roughly $12,000 to $28,000 depending on size, materials, and labor. The price drivers include foundation type, garage door features, electrical work, and whether you choose a detached or attached design. This article breaks down the cost, with realistic low, average, and high ranges for a U.S. project.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Single-car footprint | $2,500 | $4,000 | $6,000 | Typically 12×20 to 12×22 ft |
| Foundation & slab | $2,500 | $5,000 | $9,000 | Includes concrete mix, rebar, grading |
| Framing & walls | $3,000 | $6,000 | $12,000 | Wood or steel framing |
| Roofing & siding | $2,000 | $4,500 | $8,000 | Material-wood, steel, or vinyl options |
| Garage door & opener | $1,500 | $3,000 | $6,000 | Door size 9×7 or 10×8 with opener |
| Electrical & lighting | $800 | $2,000 | $4,000 | Outlets, lighting, runs to house |
| Finishes & misc. | $1,000 | $2,000 | $4,000 | Insulation, painting, trim |
| Labor & permits | $1,000 | $5,000 | $9,000 | Regional rates and permit fees vary |
Direct price components for a single-car garage project
Cost breakdown matters: materials, labor, and equipment dominate the total. The table below shows common cost categories and typical ranges for a standard 12×20 to 12×22 ft single-car setup. Assumptions include standard residential lot access in suburban areas, basic no-frills finishes, and a typical attached or detached layout.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (frame, sheathing, roofing) | $3,000 | $6,000 | $12,000 | Wood or steel frame, OSB, asphalt/shingle roof |
| Labor | $2,000 | $4,500 | $8,000 | Crew hours based on scope and access |
| Foundation & slab | $2,500 | $5,000 | $9,000 | Concrete strength and thickness vary |
| Garage door system | $1,500 | $3,000 | $6,000 | Door type and insulation affect price |
| Electrical & lighting | $800 | $2,000 | $4,000 | Outlet count and panel work cost drivers |
| Permits & inspections | $200 | $700 | $2,000 | Local variance by jurisdiction |
| Disposal & cleanup | $100 | $500 | $1,200 | Debris removal and site prep |
What drives the total: size, attachments, and site conditions
The most influential variables are footprint size, whether the garage is attached or detached, and site access. Size and layout determine foundation, framing, and door sizing, while an attached design may reduce rework on utilities. If the lot has poor drainage, extra grading or a deeper footing may be needed, increasing costs.
Material choices that move the price needle
Material selection for walls, roof, and doors can swing costs by several thousand dollars. Choosing a steel frame over wood can cut some long-term maintenance costs, but initial pricing may be higher for steel depending on local market. Siding options range from vinyl to wood to fiber cement, with vinyl usually the lowest upfront cost and fiber cement the highest in many markets.
Labor time and crew size influence pricing
Typical projects use a small crew over several days. Labor hours scale with foundation type, insulation, and interior finishes, and regional wage differences can push totals up or down. Expect higher per-hour rates in urban markets and during peak seasons.
Regional price variability and what that means for budgeting
Prices differ by region due to labor markets, material availability, and permit costs. Midwest and southern markets often cite lower base rates than coastal metro areas, while rural sites may incur extra travel fees or equipment transport costs.
Timing, permits, and potential delays
Project timing affects pricing through contractor availability and seasonal demand. Rush scheduling or after-hours work can add premiums, and permit processing times may introduce additional soft costs if done through the local building department.
Ways to reduce the single-car garage price without sacrificing safety
Smart scope management can trim costs. Choose standard 12×20 or 12×22 dimensions, simplify interior finishes, and consider attached designs to minimize utility runs. Bundling permits, or using a single contractor for framing, doors, and electrical, can reduce overhead.
