As an illustrative 2026 range, a 2-car metal garage kit runs about $7,000 to $20,000 ‹confirm› for the bare steel shell, or roughly $15 to $35 per square foot ‹confirm›, with most 20×20 to 24×24 ft builds landing near $9,000 to $15,000 ‹confirm›. Add a concrete slab, doors, and installation and the delivered, ready-to-use total often climbs to $15,000 to $30,000 ‹confirm›. Treat these as starting figures to confirm against a live quote, never a fixed price, because gauge, certification, and your local loads move the number more than the size does.
This page sits under the metal garage kits pillar and gives the full price picture for a two-car build, the question our 2-car metal garage kits guide covers in brief. Below: what drives the range, the cost by size, and where the kit price ends and the finished-garage total begins. For the per-foot method behind every number here, see the cross-silo prices pillar.
Price drivers
What moves a 2-car garage price
Two garages the same size can quote thousands apart, and the gap is rarely the square footage. Five things drive the price: how wide and tall you build, the steel gauge, whether the kit is engineer-certified for your loads, the doors and openings, and whether the number is delivered, installed, or pickup-only. Match those before you compare totals.
- Size and height. A standard two-car footprint runs 20×20 to 24×24 ft ‹confirm›. Taller walls and deeper bays for a workshop combo add steel and cost.
- Steel gauge. A 14-gauge tube frame costs less than a 12-gauge frame, and 12-gauge buys more wall and frame strength for wind or snow country ‹confirm›.
- Certification. An engineer-certified kit stamped for your local snow and wind loads costs more than an uncertified one, and most permit offices require it.
- Doors and openings. Roll-up doors, walk doors, and windows are options, not standard. See garage door options and sizes for what the openings add.
- Delivery and install. A pickup-only shell price can land thousands below a delivered, professionally erected number ‹confirm›. Always ask which one you are reading.
By size
2-car metal garage cost by size
A two-car garage is not one size, so the price spreads with the footprint. Here is how the common dimensions land as illustrative 2026 ranges for a bare, engineer-certified steel kit, before slab, doors, and installation:
| Size | Approx. sq ft | Kit shell ($) ‹confirm› | Best for |
|---|---|---|---|
| 18×20 | 360 | $6,500–$11,000 | Two compact cars, tight lot |
| 20×20 | 400 | $7,500–$13,000 | Standard two-car, the common pick |
| 22×24 | 528 | $9,000–$16,000 | Two cars plus storage or a bench |
| 24×24 | 576 | $10,000–$18,000 | Roomy two-car, workshop room |
| 24×30 | 720 | $12,000–$22,000 | Two cars plus a shop bay |
Illustrative 2026 kit-shell ranges to confirm against a live quote. Slab, doors, and installation are extra.
Read the table and the pattern is plain: the per-square-foot rate eases as the building grows, so the bigger footprint is rarely double the price of the smaller one. The 20×20 is the volume seller because it parks two cars with a little room to spare. If you want bench space or a finished floor to work on, the 22×24 or 24×24 earns its extra cost. For the next size class up, the 3-car and 4-car kits guide runs the same math.
The full total
Kit price vs the finished-garage total
The kit shell is the headline number, not the all-in cost, and the gap between them is where budgets slip. A bare two-car kit can read low because it leaves out the slab you pour, the doors you hang, and the crew you may hire to raise it. Price the whole build, not the box.
Add these to the shell
On top of the kit, budget for the site and foundation: a concrete slab runs about $4 to $8 per square foot ‹confirm›, so a 20×20 pad lands near $1,600 to $3,200 ‹confirm›. Professional installation adds roughly $2 to $5 per square foot ‹confirm› if you do not raise it yourself. Doors, insulation, and electrical are separate lines. By the time a two-car garage is delivered, erected, and usable, the total often sits well above the bare-shell figure ‹confirm›.
The honest comparison prices both sides to the same finish. A pickup-only shell against a delivered, installed building is not the same quote, and a cheaper kit that drops to a lighter gauge is a different building, not a better deal. Decide your finish level first, then read the totals. If you plan to heat or work in the space, fold insulation into the budget from day one, because adding it later costs more than building it in.
Compare the finished garage, not the bare shell on day one. The kit price tells you what one seller put in the box; the all-in total tells you what parks two cars.
