SteelBuildingKit Cost Index · Updated July 10, 2026 · Pricing collected June-July 2026
A 50×100 metal building costs $54,000 to $82,000 for the kit and $120,000 to $185,000 turnkey with a concrete slab, professional erection, and delivery (modeled national ranges, July 2026). Across 5,000 square feet that is $24 to $37 per square foot. Insulated, lit, and powered as a working warehouse, budgets run $200,000 to $280,000. This is the entry ticket to warehouse economics: the smallest footprint that leases, stores, and ships like commercial space.
Five thousand square feet is where a building stops being a big garage and starts being an asset class. Banks recognize the size, tenants search for it, and the per-square-foot math finally sits at the flat end of the curve. The scope ladder below anchors every quote you will collect; the rest of the guide prices the lines, then walks the warehouse-specific decisions: docks, power, and code. Neighboring footprints are compared throughout via the cost-by-size hub.
| Scope | What’s included | Range modeled | Per sqft |
|---|---|---|---|
| Kit only | Frames, panels, trim, fasteners, stamped drawings | $54,000 – $82,000 | $11 – $16 |
| Kit + erection | Kit plus professional assembly | $74,000 – $117,000 | $15 – $23 |
| Turnkey | Kit, delivery, 4-inch slab, erection, permits | $120,000 – $185,000 | $24 – $37 |
| Working warehouse | Turnkey plus insulation, lighting, 200A, office corner | $200,000 – $280,000 | $40 – $56 |
Baseline spec: rigid frame, 26-gauge PBR panels, 14-foot eave, one 12×12 roll-up door and one walk door, engineered for 20-40 psf snow and 115-140 mph wind. National mid-ranges, July 2026.
Ranges are modeled national estimates from published supplier price lists and advertised 50×100 pricing collected June-July 2026, cross-checked against component benchmarks: slab concrete at $6-$12/sqft, large-building erection at $4-$7/sqft, crane time at $150-$300/hr, and freight by lane. Warehouse-class buildings quote against commercial shell benchmarks of $22-$36/sqft, and our ranges bracket that band. All figures are labeled modeled; full methodology in the SteelBuildingKit Cost Index.
Turnkey building or kit package: which number are you pricing?
Two of our guides cover the 50×100 on purpose, and they answer different questions. This page prices the whole delivered project: steel, freight, concrete, labor, and permits as one turnkey budget, the number a lender or a business plan needs. If what you want is the advertised kit package: what the steel itself costs, how suppliers quote it, and how those quotes break down, that intent belongs to our 50×100 steel building kit cost guide. Read that one to shop steel; read this one to budget a building. The kit is roughly 45% of the turnkey total at this size, and the remaining 55% is where first-time warehouse budgets usually go wrong.
Where the money goes on a 50×100
| Line item | Typical range modeled | Notes |
|---|---|---|
| Steel kit (baseline openings) | $54,000 – $82,000 | One 12×12 roll-up, one walk door, 14-ft eave |
| Freight to site | $1,800 – $3,000+ | Three flatbed loads; $2 – $4/mile beyond ~250 miles |
| Site prep and grading | $2,500 – $10,000 | $0.50 – $2.00/sqft; drainage matters at this scale |
| Concrete slab, 4-inch reinforced | $30,000 – $60,000 | $6 – $12/sqft with thickened edges |
| Erection labor | $20,000 – $35,000 | $4 – $7/sqft at this size class |
| Crane | $1,500 – $3,500 | $150 – $300/hr across multiple frame days |
| Permits, engineering extras, review | $800 – $4,000 | Commercial plan review sits at the top |
| Turnkey planning total | $120,000 – $185,000 | Low ends and high ends rarely stack |
Worked example at national mid-range rates: a $67,000 kit, $2,500 freight, $4,000 site prep, $42,500 slab ($8.50/sqft), $27,500 erection ($5.50/sqft), $2,500 crane, and $2,500 permits totals $148,500, about $30 per square foot. The steel building cost calculator reruns this worksheet on your inputs; at 5,000 square feet, every dollar of slab rate is a $5,000 decision.
Docks, doors, and power: the warehouse decisions
What separates a 50×100 warehouse from a 50×100 barn is not the steel, it is three commitments made at order time. First, receiving: a grade-level 12×12 door suits box trucks and forklifts ramping in, while true dock-height receiving means either a recessed approach or a dock package, and retrofitting dock position after the slab exists is the most expensive regret at this size. Second, power and light: a 200-amp commercial service runs $5,000-$9,000 and LED high-bay lighting $2-$4/sqft (modeled, July 2026); order conduit stubs in the slab even if the buildout waits. Third, code posture: storage occupancies at 5,000 square feet generally sit below sprinkler thresholds, but local amendments and what you store can trigger them at $2-$5/sqft, so ask the fire marshal before you sign, not after. Owners planning to lease should also note what tenants search for: clear height, door count, and power, in that order. A 16-foot eave version of this building rents to a strictly larger pool than a 14-foot one. The metal warehouse cost guide carries this scope into the 10,000-square-foot class and beyond.
Configuration choices and what they cost
| Option | Typical impact modeled | Worth it when |
|---|---|---|
| Eave height 14 ft → 16 ft | +$3,800 – $7,000 on the kit | Racking, lease appeal, future tenants |
| Second 12×12 roll-up door | +$2,400 – $3,800 installed | Separate receiving and shipping flow |
| 200-amp commercial service | +$5,000 – $9,000 | Any business use; size it once |
| LED high-bay lighting | +$10,000 – $20,000 | $2 – $4/sqft; leasing and second-shift work |
| Blanket insulation, roof and walls | +$12,500 – $20,000 | Condensation control is the quiet reason |
| Skylight panel row | +$1,500 – $4,000 | Daylight over the working floor |
What 5,000 square feet actually holds
In warehouse terms: about 500 standard pallet positions in single-deep racking with forklift aisles, or roughly 750 floor-stacked. As a working building it splits cleanly into a 50×80 storage hall and a 50×20 front strip of office and receiving. The 50-foot width takes one row of interior columns off the table entirely; the whole floor is clear span, so racking layouts, lift routes, and future mezzanines never negotiate with a post. Sketch the racking and turning radii in the space visualizer tool before finalizing doors; forklift traffic decides door positions better than elevation drawings do.
How your location moves these numbers
At 5,000 square feet, location multiplies real money. Load engineering moves the kit 8-15% in heavy snow or wind counties, and a 100-foot roof collects a lot of county. Frost depth moves the foundation: northern footing packages add $4,000-$8,000 over shallow southern details at this footprint. Freight lands $1,800 near a plant and $3,000+ beyond 250 miles, in three loads that need staging room. Labor markets swing erection $10,000 or more between rural and metro crews, and the permit line runs $800 in easy counties to $4,000 with commercial plan review. Stacked, location moves a 50×100 turnkey 20-30% either way: mild-climate sites model near $120,000-$140,000, snow-belt sites near $145,000-$165,000, and coastal or heavy-review jurisdictions at $160,000-$185,000.
50×100 versus the alternatives
| Footprint | Floor | Turnkey range modeled | Trade-off |
|---|---|---|---|
| 50×80 | 4,000 sqft | $97,000 – $149,000 | Save ~$23,000-$36,000 if 100 ft overshoots |
| 40×100 | 4,000 sqft | $98,000 – $152,000 | Cheaper entry, but 40-ft width limits racking aisles |
| 50×100 (this guide) | 5,000 sqft | $120,000 – $185,000 | The entry warehouse benchmark |
| 60×100 | 6,000 sqft | $140,000 – $215,000 | +1,000 sqft and a wider clear span |
Against the 40×100, the extra 10 feet of width is what buys real racking-plus-aisle geometry; storage rows that work on paper at 40 feet often lose an aisle in practice. Stepping up, the wider-span economics of the 60-foot family are their own subject, covered rung by rung in the size hub.
The 50×100 quote checklist
At this size you are running a small commercial project, and the quotes should read like it.
- Scope in writing: kit, kit plus erection, or turnkey, at one identical written spec
- Stamped drawings for YOUR county’s loads, plus occupancy classification stated if commercial
- Eave height decided against racking and lease plans, not habit; 16 ft is the lease-friendly answer
- Door schedule mapped to traffic flow: receiving, shipping, and personnel separately
- Slab bid to the anchor-bolt plan, with conduit stubs and any dock details cast in, not cut in
- Freight quoted to your address with load count and staging plan for three flatbeds
- Crane days and rate ($150-$300/hr) on a named quote
- Sprinkler question answered by the fire marshal in writing before deposit
- Price-lock window (typically 7-30 days) aligned with your lender’s timeline

50×100 metal building FAQs
How much does a 50×100 metal building cost in 2026?
$54,000-$82,000 for the kit, $120,000-$185,000 turnkey with slab, erection, and delivery (modeled July 2026). Fitted out as a working warehouse with insulation, lighting, and 200-amp power, plan on $200,000-$280,000. County loads, concrete markets, and commercial review set your position in the range.
What does a 50×100 cost per square foot?
Turnkey, $24-$37 per square foot; the kit alone runs $11-$16/sqft (modeled July 2026). That sits squarely inside the $22-$36/sqft commercial shell band, which is why 5,000 square feet is where steel buildings start competing as leasable warehouse space.
Is a 50×100 metal building a good rental investment?
The economics that matter: $120,000-$185,000 turnkey against local small-warehouse rents, which commonly run several dollars per square foot per year. Clear height, door count, and power drive tenant demand, so the $3,800-$7,000 spent on a 16-foot eave typically returns first. Model it against real local comps, not national averages.
Does a 50×100 need fire sprinklers?
Often not at this size for basic storage occupancies, but thresholds are local and cargo-dependent, and sprinklers run $2-$5/sqft when triggered. High-piled storage, certain commodities, and local amendments change the answer. One written question to the fire marshal before ordering beats a $15,000 surprise after.
What is the difference between this price and the 50×100 kit price?
Scope. The kit is the engineered steel package, $54,000-$82,000 (modeled July 2026). Turnkey adds concrete, erection, freight, and permits, roughly $66,000-$103,000 more. Our separate 50×100 kit cost guide covers shopping the package; this page budgets the finished building.
How long does a 50×100 project take?
Plan on 12-20 weeks: 3-8 weeks engineering and permits (commercial review sits at the long end), 6-10 weeks fabrication, slab poured in parallel with 7 days minimum cure, then 7-10 working days of erection with crane support. Ordering 10-14 weeks ahead of need keeps you off the expensive end of every schedule.
What does an office corner inside a 50×100 cost?
Interior buildout runs $20-$60 per square foot of finished space (modeled, July 2026), so a 20×25 office corner lands around $10,000-$30,000 depending on finish level, HVAC, and whether a bathroom rides along. Rough in the under-slab plumbing at pour time even if the office is a someday plan; the $1,500-$4,000 rough-in beats cutting a finished slab for many times that. Sleeve an electrical conduit to the corner in the same pour; a wired, plumbed office corner leases and appraises like real space instead of an afterthought. At warehouse scale, that corner is also what turns a shell lease into an operating business address.
