A two-car garage shed typically costs $12,000-$45,000, depending on whether the price covers a basic kit or a completed, permitted structure. Building size, framing material, foundation, site access, and local labor rates account for most of the difference.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Garage kit | $7,000 | $14,000 | $24,000 | Materials only, usually 20 by 20 to 24 by 24 feet |
| Installed garage | $12,000 | $28,000 | $45,000 | Basic to midrange build; site work and permits vary |
| Concrete slab | $2,500 | $4,500 | $8,000 | About $5-$10 per square foot |
| Premium wood build | $30,000 | $42,000 | $60,000+ | Finished exterior, upgraded doors, or complex site |
What a 24-by-24 two-car garage shed costs
A basic 20-by-20-foot metal garage kit commonly runs $7,000-$13,000, while a 24-by-24-foot kit with heavier framing or upgraded doors can reach $15,000-$24,000. These prices generally cover the building package, not the slab, assembly, electrical work, or permits.
For a standard 24-by-24-foot structure, an installed metal garage often costs $18,000-$32,000. A wood-framed garage with siding and shingle roofing is more often $25,000-$45,000. A complete, ready-to-use build typically costs substantially more than the advertised kit price. Assumptions: U.S. suburban location, standard finishes, level access, and no major utility extensions.
How materials, labor, and foundation shape a 24-by-24 quote
Quotes differ in what they include. The table shows common budget ranges for a 576-square-foot garage; local rates, specifications, and site conditions can move each line item.
| Quote component | Typical price | Common pricing basis | What changes the charge |
|---|---|---|---|
| Building materials | $7,000-$24,000 | $12-$42 per sq ft | Metal gauge, lumber, siding, roof, doors |
| Assembly labor | $4,000-$12,000 | $50-$100 per crew hour | Crew size, access, and framing complexity |
| Concrete slab and base | $2,500-$8,000 | $5-$14 per sq ft | Thickness, reinforcement, excavation |
| Permits and inspections | $200-$2,000 | Varies by jurisdiction | Plan review, zoning, local code |
| Delivery and site work | $500-$5,000 | Per project | Distance, grading, removal, truck access |
Labor estimates can be checked with . For example, 60-100 crew hours at $50-$100 per hour equals $3,000-$10,000 before specialized equipment or subcontracted electrical work. Confirm whether the quote includes the slab, doors, delivery, assembly, and cleanup.
Why width, wall height, and roof load change the price
A 20-by-20-foot garage provides 400 square feet, while a 24-by-24-foot version provides 576 square feet. The larger footprint can add several thousand dollars in building materials and foundation expense. A 24-foot width is also more practical when two vehicles need room for doors and storage.
Standard 8-foot walls usually cost less than 10- or 12-foot walls, which require more framing and siding. Snow-load requirements can also raise costs: a building engineered for heavy snowfall may need stronger trusses and bracing. Ask the supplier to price the required local wind and snow ratings rather than comparing structures with different specifications.
Can a metal garage kit cost less than a wood build?
Metal kits often have the lowest initial price and can be assembled quickly, but the base package may omit a slab, insulation, interior finish, and some doors. A professionally assembled metal garage with a slab may cost $18,000-$32,000. A wood-framed version with similar floor area commonly lands at $25,000-$45,000, especially with siding and asphalt shingles.
Wood offers more flexibility for matching a house or adding conventional wall finishes, while metal can reduce material and maintenance costs. A kit is not automatically cheaper after delivery, foundation, tools, and hired labor are included. Compare completed scopes, not just the price printed on each kit listing.
How long does a two-car garage take to install?
Site preparation and a concrete slab may take several working days, followed by curing time before heavy assembly. A prefabricated metal structure can often be assembled in 1-3 days with an experienced crew; a wood-framed garage may take 1-3 weeks, excluding permit delays and weather interruptions.
Professional assembly commonly costs $4,000-$12,000, depending on crew size, structure type, and whether the contractor handles roof, doors, and trim. Electrical service or insulation may require separate trades. Get a written schedule that separates site work, slab curing, framing, and finish work.
How permits, concrete, and delivery add to the bill
Permit charges range from a few hundred dollars to about $2,000, though some areas require engineered plans or zoning review that add expense. Electrical permits and inspections may be separate. Requirements depend on local rules, so a supplier’s standard design may need adjustment for setbacks, snow load, or wind exposure.
Sloped or soft ground can add $1,000-$5,000 for grading, drainage, or removal of an old structure. Delivery may be included nearby but can cost several hundred to more than $1,500 for a distant or difficult site. Request separate prices for permits, excavation, hauling, slab work, and delivery before signing.
Ways to lower a two-car garage shed quote
Keep the footprint near a standard size, choose a basic door and roof package, and avoid extra windows or decorative upgrades unless they serve a clear purpose. A level, accessible site can reduce equipment and labor charges. If a usable foundation already exists, ask whether it meets the manufacturer’s specifications before paying for a replacement.
Compare at least three itemized quotes that specify dimensions, material gauge or framing grade, roof rating, slab thickness, assembly, and exclusions. Buying a kit and arranging assembly separately may save money, but only if delivery, tools, warranty terms, and responsibility for errors are clear. Price the complete installed structure before choosing the lowest advertised kit.
