At 1,500 square feet, a 30×50 is the largest of our compact sizes and the point where a single building can comfortably combine two functions — storage plus workshop, or garage plus small living space — without feeling cramped. The extra 20 feet of length over a 30×30 goes a long way for anything oversized, like a boat, RV, or a run of equipment bays, while the footprint still fits on most suburban or rural lots without requiring a variance for lot coverage.

| Turnkey (installed) | $36,500–$42,900 total (~$26.46/sq ft avg) |
| Concrete foundation add-on | ~$7,500 |
| Professional labor add-on | $3–$5/sq ft |

Popular Uses for a 30×50 Metal Building
At the top of our small-to-mid size range, a 30×50 has enough length to handle oversized items and enough total space to split between two uses:
- RV and boat storage with workshop space left over — the 50-foot length comfortably fits a Class A motorhome or larger boat with room for a bay to spare
- Small barndominium with an open living area — this footprint gives more breathing room than a 30×40 shell for anyone planning to finish part of the space as living quarters; see our barndominium options for what that conversion involves
- Multi-bay garage for a car collection — three to four vehicles depending on layout, well beyond what a standard attached garage offers
- Combined workshop and storage for a small business — equipment on one end, inventory or finished goods on the other
- Home gym plus storage combo — a dedicated fitness space without giving up all your storage capacity
- Hobby or event space — band practice, an art studio, or occasional small gatherings, where a single large open room matters more than a split layout

What’s Included
Kit-only pricing on a 30×50 building covers the primary steel frame, roof and wall panels, one walk door, one drive-in door, engineering stamps sized to your local code, and delivery to your site — the complete structure, ready to assemble.
Turnkey pricing adds the concrete foundation, professional erection and labor, and permit coordination on top of that, so the building arrives finished and ready to use rather than as a kit waiting on a crew — a bigger consideration at 1,500 sq ft than at smaller sizes, since erection takes more time and equipment.
Not included at either level: insulation, interior finish-out, custom colors, additional windows beyond the standard package, and electrical or plumbing rough-in. See insulation options and finishing options for what those typically add to a 30×50.
What Affects Your Price
- Foundation type — a standard 4″-6″ slab is the baseline; a foundation built for heavier equipment (like a vehicle lift) or difficult soil costs more
- Region — labor rates and code requirements vary by state, and a 30×50 involves more labor hours than a smaller kit, which amplifies regional differences; check your state page
- Finishing level — insulation, interior walls, and custom exterior colors are priced separately from the base structure
- Door and window count — the standard kit includes one walk door and one drive-in door; splitting the building into multiple bays typically means adding more of both
Foundation Requirements for a 30×50
A 30×50 building typically sits on a standard 4″-6″ concrete slab, estimated at around $7,500 for this footprint — the largest foundation estimate among our compact sizes, reflecting the extra material and pour time a 1,500 sq ft slab requires.
- Soil conditions — soft, sandy, or expansive soil may require added reinforcement, especially important if the slab needs to support heavy vehicles or equipment
- Site prep — clearing, grading, or drainage correction adds to the base foundation cost, and a larger footprint means more area to prep
- Frost line depth — colder climates often require deeper footings, which raises both material and labor cost

Common Mistakes to Avoid
| Mistake | Why It Costs You | Fix |
|---|---|---|
| Comparing a kit-only quote here to someone else’s turnkey number | Turnkey includes foundation and labor, so the two prices aren’t measuring the same thing | Confirm whether every quote you’re comparing is kit-only or fully installed |
| Undersizing below 30×50 to save on sticker price when you need both storage and workshop space | Splitting one function off into a second structure later almost always costs more than building the larger footprint upfront | Size for your combined use case, not just the smallest number that technically fits your primary need |
| Skipping a soil or site assessment before ordering | At 1,500 sq ft, unexpected soil conditions can meaningfully change the foundation estimate after your budget is set | Get a soil and site check before finalizing your foundation number |
| Leaving finishing decisions for after the structure is up | Retrofitting insulation or interior finish-out costs more than specifying it at the time of your quote, especially across a larger footprint | Decide on your finishing level, particularly if part of the space will be living quarters, before your building ships |

FAQ
How much does a 30×50 metal building cost?
Kit-only pricing for a 30×50 (1,500 sq ft) building typically runs $25,700–$30,200, or about $18.66 per square foot. A turnkey, fully installed building typically runs $36,500–$42,900, or about $26.46 per square foot, before finishing options.
What can I fit in a 30×50 building?
A 30×50 comfortably fits RV or boat storage with workshop space left over, a multi-bay garage for a car collection, a small barndominium with an open living area, combined workshop and business storage, or a home gym plus storage combo.
Do I need a permit for a 30×50 metal building?
Nearly always yes, and at this size expect a more thorough review than for a small garage, particularly if you’re planning any residential finish-out. Check your state page for local permitting guidance before you order.
Is a 30×50 metal building hard to construct myself?
The steel structure is manageable for an experienced crew with proper equipment, but a 1,500 sq ft clear-span roof takes meaningfully more labor and coordination than our smaller sizes. Most owners at this size bring in professional labor for at least the erection.
What size foundation does a 30×50 building need?
A standard 4″-6″ concrete slab sized to the building’s 1,500 sq ft footprint, estimated at around $7,500 depending on soil conditions and site prep.
Can I finance a 30×50 metal building?
Yes. See financing options and rent-to-own for ways to spread out the cost instead of paying in full upfront.
