30×50 Pole Barn Cost (2026): Kit, Contractor & Finished Prices

The 30x50 is a popular mid-size pole barn — 1,500 square feet gives you meaningfully more room than a 30x40 without jumping to the cost of a full 40x60. It’s the go-to size for a 3-car garage with shop space, a small horse barn with 3–4 stalls, or a farm equipment building with room for a tractor and implements.

In 2026, a 30x50 pole barn costs between $14,000 and $65,000 depending on whether you’re buying a kit, having it erected, or going fully finished.

30×50 Pole Barn Price Overview

Configuration	Price Range
Kit only (materials)	$14,000–$24,000
Kit + hired erection crew	$22,000–$34,000
Contractor-built (shell only)	$24,000–$42,000
With concrete slab	$33,000–$53,000
With slab + electrical + insulation	$42,000–$65,000

Per-Square-Foot Costs

At 1,500 square feet, the 30x50 sits right between the 30x40 (1,200 sf) and 40x60 (2,400 sf) in per-square-foot pricing:

Build Level	30×50 Cost/Sq Ft	30×40 for Comparison	40×60 for Comparison
Kit only	$9–$16	$10–$17	$8–$15
Shell (contractor)	$16–$28	$17–$30	$15–$25
Shell + slab	$22–$35	$24–$38	$22–$35
Finished	$28–$43	$30–$45	$27–$42

You’ll pay slightly less per square foot than a 30x40 (more floor area spreads fixed costs) but slightly more than a 40x60 (which benefits from greater economies of scale).

Kit Pricing for a 30×50

A 30x50 pole barn kit from a national manufacturer runs $14,000 to $24,000 and includes:

• 10–14 treated laminated columns (6x6 minimum)
• Pre-engineered trusses (30’ clear span) at 4’ on center
• Purlins, girts, and all framing hardware
• 29-gauge steel roof and wall panels
• Ridge cap, corner trim, eave and rake trim, all flashing
• Fasteners and sealant
• One overhead door frame opening (10×10 or 12×12)
• One walk-in door frame opening (3×7)

Not included in most kits:

• Concrete slab or gravel floor prep ($6,000–$12,000 for a slab)
• Overhead doors (the kit provides the opening, not the door itself — budget $800–$2,500 per door)
• Electrical wiring ($2,500–$5,000)
• Insulation ($4,500–$8,000 for fiberglass; $7,000–$12,000 for spray foam)
• Site prep and grading ($1,000–$4,000)

What Makes a 30×50 Different from a 30×40 or 40×60?

30×40 (1,200 sf): The classic 2–3 car garage. Adequate for storage and a small work area but tight if you want shop space alongside vehicles.

30×50 (1,500 sf): Adds 25% more floor space for only 10–15% more cost. The extra 10 feet of depth is the difference between “garage with no room to work” and “garage with a proper workshop.” Most useful for owners who want dedicated work/hobby space beyond just parking.

40×60 (2,400 sf): 60% more floor space than the 30x50, but 40–50% more expensive. The jump to 40’ width enables wider clear spans, side-by-side bays, and more flexible layouts. Worth it if you’re storing large equipment or need a commercial-scale building.

Common Uses for a 30×50

• 3-car garage with workshop: Two 10×10 overhead doors for vehicles + 10 feet of shop depth at the back
• Small horse barn: 3–4 stalls (10×12 each) with a center aisle and tack room
• Farm equipment storage: Room for a tractor, implements, and workbench
• RV or boat storage: 50’ depth handles most Class C RVs with room to spare
• Hobby shop: Woodworking, auto restoration, welding — 1,500 sf gives breathing room

Concrete Slab Options

A full 30x50 (1,500 sf) concrete slab costs $6,000–$12,000 depending on your region and spec:

Slab Type	Cost	Best For
4” slab, wire mesh	$5,500–$8,500	Light storage, hobby shop
6” slab, rebar reinforced	$7,500–$11,500	Vehicles, equipment, daily use
6” slab, turned-down edge	$8,500–$12,000	Cold climates, heated buildings

Gravel floor alternative: 6” compacted gravel with geotextile fabric costs $1,500–$3,000 for a 30x50. Good for agricultural storage and equipment buildings where a smooth floor isn’t required.

Frequently Asked Questions

How much does a 30x50 pole barn kit cost?

A 30x50 pole barn kit runs $14,000–$24,000 in 2026, depending on manufacturer, steel gauge, and included features. This covers materials only — add $8,000–$12,000 for professional erection if you’re not building it yourself.

Is a 30x50 big enough for a shop?

Yes — 1,500 square feet is a solid workshop. You can fit 2 vehicles, a workbench area, tool storage, and a welding/fabrication station. For reference, a typical 2-car residential garage is 400–600 sf, so a 30x50 is 2.5–3× that.

How long does it take to build a 30x50 pole barn?

Shell erection takes 2–4 days for an experienced crew. With concrete, electrical, and finishing, expect 3–6 weeks from start to completion. Kit lead times add 4–8 weeks on top.

30x40 or 30x50 — which should I build?

Build 30x50 if your budget allows. The extra 10 feet of depth costs only 10–15% more but adds 25% more usable space. Nearly everyone who builds a 30x40 wishes they’d gone 30x50. The cost difference is typically $3,000–$6,000 for a shell — a modest premium for space you’ll use for decades.
