Metal Garage Kits, Sized and Priced
Garages are what engineered steel does best: clear-span space, a bolt-together kit, and a price that beats stick framing at every size past two cars. Here's what the common sizes really cost in 2026 and the two specs that matter more than anything else.
2026 kit prices by garage size
| Garage kit (engineered, delivered) | Typical 2026 range |
|---|---|
| 1-car · 20×30 (600 sq ft) | $8,000 – $14,000 |
| 2-car · 24×30 (720 sq ft) | $9,500 – $16,500 |
| 3-car · 30×40 (1,200 sq ft) | $13,500 – $23,500 |
| 4-car · 40×40 (1,600 sq ft) | $17,000 – $30,000 |
Erection roughly adds 50–60% of kit price; a turnkey build with slab lands near 2.2–2.4× the kit number.
The two specs that matter
- Door size: a modern truck wants a 10-ft-wide door minimum; anything with a roof rack or a lift kit wants 8 ft of height. Spec 10×8 doors unless the building is purely for cars.
- Eave height: 10 ft standard fits a door and opener; a vehicle lift needs 12 ft minimum, 14 ft to work comfortably under a truck.
Kit vs. carport vs. stick-built
- Vs. tube carports: engineered red-iron kits carry real wind/snow stamps, take any door, and appraise as permanent structures — tube steel mostly doesn't.
- Vs. stick-built: past ~700 sq ft, steel wins on price and goes up in a third of the time; under that, framing lumber competes.

How much does a metal garage kit cost?
In 2026: roughly $8,000–$14,000 for a 1-car 20x30, $9,500–$16,500 for a 2-car 24x30, $13,500–$23,500 for a 3-car 30x40, and $17,000–$30,000 for a 4-car 40x40, delivered with engineered plans.
Are metal garage kits hard to build yourself?
A 2-car kit is a realistic DIY project for two or three people with a weekend-warrior skill set, a manlift rental, and patience. Past 30-ft spans, most owners hire an erection crew.
