A 30×60 metal building kit encloses 1,800 square feet, a footprint 30 feet wide and 60 feet deep. That is a true clear-span shop floor: six vehicles parked across two rows, a four-bay garage with a workshop behind it, or a barn long enough to line up tractors, trailers, and an RV under one roof. At 1,800 square feet a 30×60 leaves the homeowner-garage class behind and reads as a working shop, a small commercial bay, or an agricultural barn.
This guide sits under the metal building sizes pillar, and it covers one footprint in depth: what fits inside the 1,800 square feet, the jobs a 30×60 does well, the frame and options you will see on a quote, the clear heights you can order, and an illustrative 2026 price range. To weigh this size against every other footprint, the metal building size chart lays them out side by side.
1,800 square feet
What a 30×60 metal building kit covers
Thirty feet wide by sixty feet deep gives you 1,800 square feet of enclosed floor. The 30-foot width is the number that changes the building: it is a full three-car span across, wide enough to back equipment in and still walk the perimeter, and on a clear-span frame it holds that width with no posts in the middle of the floor. The 60-foot depth then runs long enough to split the building into zones, parking up front and a shop, a wash bay, or storage down the back.
Think of it as two of the popular 30×40 shops set end to end, or a barn you can drive a truck and trailer straight through. The jump in both width and depth over a 30×50 turns a large garage into a building that handles a small business or a working farm. If 1,800 square feet is more than you need, the 30×40 trims the depth while keeping the same wide floor.
What fits
What fits inside a 30×60 building
Up to six vehicles, or a mix of vehicles, equipment, and a full shop. The table below shows how a 30×60 handles the loads buyers park in this size, so you can match the footprint to the job before you order.
| What you want to store | How a 30×60 handles it |
|---|---|
| Six cars, two rows of three | Three across the 30-foot width, parked in two rows down the depth, with aisle room |
| Four bays plus a workshop | Four roll-up bays up front, a full bench, tool wall, and floor space across the back |
| RV plus a boat and a shop | A long rig down one side, a trailered boat beside it, and a work area still left over |
| Truck and trailer drive-through | Doors on both ends let a rig pull straight through without backing up |
| Tractors and farm equipment | Several implements, a tractor, and a feed or tack corner under one roof |
| Small commercial or trade shop | Work trucks, a parts counter, racking, and a bay or two for service work |
What clears at this size. A 30×60 is a three-lane, two-row footprint with real depth in each lane.
Mind the door, not just the floor
A motorhome, a dump trailer, or a topped truck can fit the floor plan and still hit the door header. The roll-up opening sets your real clearance, so order the door height around the tallest thing you park. The how to choose a size guide walks through measuring before you buy.
Common uses
Common uses for a 30×60 footprint
The 1,800-square-foot footprint sits where personal storage ends and working buildings begin: large enough to run a business or a farm out of, yet still ordered as a kit a crew can raise on a slab. These are the jobs it does best:
- Large home or hobby shop. A serious workshop with multiple vehicle bays, a fabrication corner, and room for a lift, all on one wide clear floor.
- Commercial or trade base. A contractor, mechanic, or welder housing work trucks, materials, and a service bay. For layout ideas across building types, see what people build with steel.
- RV, boat, and toy storage. A long rig, a boat, and a couple of toys off the weather, with the depth to park them in a line rather than shuffling.
- Agricultural barn. Equipment, hay, and a tack or feed room under a dry, lockable roof, in the same class people reach for in metal garage and barn kits.
- Barndominium shell. Insulate and line part of the depth for living space and keep the rest as a shop, the wide floor that underpins many a metal building home build.
If covered space matters more than a fully enclosed room, the same footprint works as an open or partly enclosed cover for less. Compare it against the shorter 30×50 and the wider 40×60 before you commit, since ten feet in either direction changes both what the building holds and what it costs.
Frame and options
The frame, doors, and clear height
At a 30-foot width the frame question is settled for most buyers: bolt-up red iron is the standard pick, because the structural I-beam clears the floor of interior posts and carries the load a building this size has to hold. Light-gauge tube steel exists at the budget end, but it leans on interior posts to span 30 feet, which eats into the open floor a shop or barn wants. Frames are sold by wall thickness in gauge, where a lower number means thicker steel; order the certified load rating for your county so the kit is stamped for local snow and wind, not just the base spec ‹confirm›.
Clear height is where buyers most often under-order. The eave height, the wall height at the side, sets how tall a door you can hang and how much headroom you keep inside. A 30×60 is commonly offered with side walls from about 12 to 20 feet ‹confirm›. Twelve feet suits a standard shop and a car lift; go to 16 feet or more if you want a tall RV, a second-floor mezzanine, or commercial roll-up doors that clear a box truck.
On the options list you choose a roof style, the doors, and any openings. Multiple roll-up doors plus a walk-in door and several windows cover most multi-bay shops, and a door on each end lets a rig drive through. The roof comes as a standard, A-frame, or vertical-rib style, with the vertical roof shedding water and snow better for a small premium. Insulation belongs on the list too if you will heat the space, since 1,800 square feet is a lot of floor to warm.
Order the size you will grow into, not the one that just fits today. A few feet of eave height or an extra roll-up door costs far less now than a rebuild later.
Price
What a 30×60 metal building kit costs in 2026
As a 2026 illustration, a 30×60 steel shell kit runs roughly $22,000 to $45,000 ‹confirm› for the bare building. The spread is wide because frame gauge, eave height, roof style, door count, wall enclosure, and the certified load rating each move the number. A partly open cover with a lighter spec sits near the bottom; a fully enclosed, certified red iron shop with several roll-up doors and a tall eave sits near the top ‹confirm›.
That figure is the kit alone. Budget separately for a concrete slab, delivery, permits, and any insulation or interior finish, which on a building this size can add many thousands of dollars ‹confirm› on top of the shell. For the full breakdown of what drives the total and how to read a quote line by line, see the metal building kit prices pillar.
Treat any single number with care: prices move with the steel market, your location, and the season. Get a written quote stamped for your address, confirm the frame gauge and the load rating, and check the figure against current ranges in the size chart before you sign.
FAQ
30×60 metal building kits: common questions
How many square feet is a 30×60 building?
A 30×60 building is 1,800 square feet, found by multiplying 30 feet of width by 60 feet of depth. That is the size of a working shop or a small barn, large enough for six vehicles in two rows, a four-bay garage with a workshop, or equipment and storage under one roof.
How many cars fit in a 30×60 garage?
Up to six standard cars, parked three across the 30-foot width in two rows down the 60-foot depth, with room to open doors and walk the aisles. Many owners instead park two or three vehicles and keep the rest of the floor for a shop, equipment, or RV and boat storage.
How much does a 30×60 metal building cost?
As a 2026 illustration, the bare shell kit runs roughly $22,000 to $45,000 ‹confirm›, depending on frame gauge, eave height, doors, roof style, wall enclosure, and the certified load rating. A slab, delivery, permits, and insulation are extra. Always get a written quote stamped for your location.
How tall can a 30×60 building be?
Side wall, or eave, heights of about 12 to 20 feet ‹confirm› are common at this size. Twelve feet suits a standard shop and a car lift; order 16 feet or taller if you want a tall RV, a mezzanine, or doors that clear a box truck. The eave height sets how tall a door you can hang.
Does a 30×60 kit use tube steel or red iron?
Red iron is the standard pick at this width. Light-gauge tube steel can reach 30 feet only by adding interior posts, which break up the floor a shop or barn wants open. A red iron frame gives you a clear span with no center post and a higher load rating, which is why most 30×60 kits are framed in it.
Do I need a permit for a 30×60?
Almost always. At 1,800 square feet on a permanent foundation, a 30×60 sits well past the permit threshold in nearly every county. Check with your local building department before you order, since the answer shapes your foundation, your tie-downs, and the certified load rating the kit needs to carry.
Will an RV fit in a 30×60 building?
Easily, on the floor. The 60-foot depth clears even the longest motorhomes with room to spare, and the 30-foot width leaves space for a second vehicle alongside. The limit is roof height, so order a 14-foot or taller eave and a matching roll-up door, and confirm the clear opening before you buy.
