24×30 Metal Building
720 sq ft 12 to 16 ft eave
A 24×30 metal building gives you 720 square feet of clear-span, column-free space, enough room for two vehicles plus a work bench, a single bay with generous storage, or a compact shop. As a US manufacturer, Universal Steel of America engineers, fabricates and ships this size as a pre-engineered steel building, certified to your local snow, wind and seismic code rather than sold as a one-size carport.
Every 24×30 is drawn for your address, fabricated at the plant nearest you and delivered ready to assemble, with professional erection available as an optional service. You choose the eave height, door and window openings, panel color and insulation, so the finished building matches how you actually plan to use the 720 square feet.

Popular uses for a 24×30 Metal Building
Two-car garage with room to spare
The 24x30 footprint parks two vehicles side by side and still leaves the back 6 feet for storage, shelving or a workbench. The 24 ft clear span means no interior columns to steer around when you pull in. It is the natural step up for homeowners who have outgrown a standard two-car garage.
Metal garagesContractor or hobby workshop
At 720 square feet there is room for a vehicle bay plus a dedicated work area with benches, tooling and storage walls. Add a taller eave and extra openings for natural light and ventilation. A clear-span steel shell gives you an open floor you can lay out however your trade or hobby demands.
Shop buildingsRV, boat and vehicle storage
Specify a 14 or 16 ft eave and a tall roll-up door and a 24x30 will swallow a Class C RV, a boat on a trailer or a lifted truck under cover. The 30 ft depth clears most travel trailers with room to walk around them. Enclosed steel keeps weather, UV and debris off your investment year round.
RV and boat storage buildingsLight agricultural and equipment building
For a small farm, ranch or acreage, 720 square feet stores tractors, implements, ATVs, mowers and feed out of the weather. The column-free interior makes it easy to drive equipment straight in and back out. Wide framed openings can be added to suit larger machinery.
Agricultural steel buildingsGeneral and seasonal storage
A 24x30 works as secure, dry storage for furniture, inventory, seasonal gear, kayaks, golf carts and lawn equipment. Steel walls and a locking door give you better protection from theft and weather than a fabric or wood structure. Insulation and venting can be added to control condensation on stored goods.
Small commercial or trade space
The 24x30 size suits a small commercial or service operation that needs a clear-span bay plus a front office or counter area. It is a cost-effective footprint for a startup shop, a satellite location or a trade business that has outgrown a home garage. We engineer it to commercial code for your jurisdiction.
Commercial steel buildingsWhat fits in 720 square feet
At 24 feet wide and 30 feet deep, this size comfortably parks two cars or a truck and a daily driver, with the extra depth left over for shelving, a workbench or lawn and garden equipment. The 24 ft clear span keeps the floor free of interior columns, so you can rearrange the layout without working around posts. It is one of the most popular sizes for homeowners who have outgrown a standard two-car garage but do not need a full shop.
Choosing your eave height
Eave height is what tailors a 24×30 to its job. A 12 ft eave suits a standard garage or workshop, while stepping up to 14 or 16 ft creates the door clearance an RV, boat or lifted truck needs. Taller walls also make room for a car lift or overhead storage. We size the columns and bracing to the eave and the loads at your site, so the taller option is engineered, not improvised.
Workshops, storage and light agricultural use
The same 720 square foot footprint works as a contractor or hobby workshop, dry storage for equipment and seasonal gear, or a light agricultural building for a small farm or acreage. If you are weighing living quarters or a small barndominium shell at this footprint, 24×30 is on the tight side for a full residence, so most buyers move up in size; you can compare layouts on our barndominium page.
24×30 Metal Building questions
How much does a 24x30 metal building cost?
An engineered 24x30 steel shell is typically around $10,500 to $15,000 delivered, and a fully installed turnkey building generally runs about $18,000 to $31,000 once you add the foundation, erection, insulation and openings. The exact figure depends on your eave height, snow and wind loads, and finish. These are industry-typical estimates, not a quote, so request a free quote for pricing engineered to your site.
How much does it cost to have a 24x30 garage built?
A complete, professionally erected 24x30 metal garage on a concrete slab usually falls in the $18,000 to $31,000 range, with the foundation adding roughly $4,300 to $8,600 and erection around $4,000 to $8,000. Costs swing with local concrete and labor rates, site prep and permits. A steel building is delivered ready to assemble, and professional erection is an optional service rather than a requirement.
How many cars can fit in a 24x30 garage?
A 24x30 garage holds two full-size vehicles parked side by side, with the extra 6 feet of depth left for a workbench, shelving or storage. With a single wide door it works as a deep one-car bay plus shop space, and with two doors it functions as a true two-car garage. The 24 ft clear span keeps the parking area free of interior columns.
Is it cheaper to build a metal building or wood?
At this size a pre-engineered steel building is usually cheaper than a comparable wood or pole barn over its life. Steel needs less framing labor, ships as an engineered package and resists rot, termites, fire and warping, which lowers maintenance and insurance over time. A pole barn can have a lower sticker price on the smallest builds, but steel closes the gap quickly once you factor in durability and code-rated load capacity.
What is the typical eave height for a 24x30 metal building?
Most 24x30 buildings use a 12 to 16 ft eave. A 12 ft eave suits a standard garage or workshop, while 14 to 16 ft gives the door clearance an RV, boat or lifted truck needs and the headroom for a car lift or overhead storage. Universal Steel engineers the columns and bracing to whatever eave height and loads your project calls for.
Do I need a concrete foundation for a 24x30 metal building?
Most 24x30 buildings are anchored to a concrete slab, which gives a level, durable floor and the strongest anchorage in high wind and snow areas. Budget roughly $6 to $12 per square foot for the slab depending on your site and region. Some buyers anchor to piers or a gravel pad for storage uses, though local code and your intended use determine what is allowed.
