30×30 Pole Barn Cost (2026): Square Garage & Workshop Pricing

The 30x30 pole barn is the square footprint sweet spot — 900 square feet of column-free workshop or garage space in a perfectly symmetrical layout. Square buildings are easier to plan around, photograph well for resale listings, and often fit lot constraints where a long rectangular building wouldn’t. The 30-foot truss span gives you full clear-span flexibility (no interior posts) at a moderate price step up from the 24-foot span.

In 2026, a 30x30 pole barn costs between $7,500 and $40,000 depending on configuration and finish.

30×30 Pole Barn Price Overview

Configuration	Price Range
Kit only (materials)	$7,500–$13,000
Kit + hired erection crew	$12,000–$19,000
Contractor-built (shell only)	$14,000–$23,000
With concrete slab	$20,000–$30,000
With slab + electrical + insulation	$25,000–$36,000
Fully finished interior	$32,000–$45,000

Per-Square-Foot Costs

Build Level	30×30 Cost/Sq Ft	30×40 for Comparison
Kit only	$8–$14	$8–$14
Shell (contractor)	$16–$26	$15–$25
Shell + slab	$22–$33	$22–$32
Finished	$30–$42	$28–$40

The 30x30 has nearly identical per-square-foot economics to the 30x40 — same truss span, same column count per linear foot, same per-foot kit pricing. The decision between them is really just “how much building do I need?”

Kit Pricing for a 30×30

A 30x30 kit runs $7,500 to $13,000:

• 6–8 treated laminated columns (8’ on center)
• Pre-engineered trusses (30’ clear span) at 4’ on center
• Purlins, girts, and framing hardware
• 29-gauge steel roof and wall panels
• Trim, flashing, and fasteners
• One overhead door frame opening (typically 10×10 or 12×10)
• One walk-in door frame opening

The 30-foot truss span is heavier than 24-foot but still within reach of a 4-person crew without crane rental. Many DIY builders use a tractor with a front-loader to lift trusses into place.

30×30 vs 30×40 — Should You Stretch It?

Factor	30×30	30×40
Square footage	900 sf	1,200 sf
Kit cost	$7,500–$13K	$9K–$16K
Contractor shell	$14K–$23K	$17K–$27K
Cost per added 100 sf	n/a	~$1,500 (very efficient)
Resale appeal	Solid	Higher (more popular)

Bottom line: Stretching from 30x30 to 30x40 adds 33% more space for ~20% more cost. If your lot can handle the extra 10 feet of length, the 30x40 is the better economic choice. The 30x30 wins when:

• Lot constraints / setbacks force a square footprint
• You explicitly want a square aesthetic (often paired with hipped roofs)
• Budget is tight and the extra 300 sf isn’t needed

Common Uses for a 30×30

• 2-car garage with workshop: Two 9x8 doors on one wall + 12 feet of workshop depth on the back wall. The square layout makes the workshop feel less like an afterthought than in a long rectangular building.
• Workshop / hobby shop: 900 sf is the minimum for a serious hobby shop. Room for a workbench wall, dust collection, table saw, and project area.
• Equipment storage: Tractor, mowers, ATV, trailer, snowblower. Single 12x10 overhead door provides comfortable drive-in access.
• Square hipped-roof aesthetic: Some homeowners build 30x30 specifically to support a hipped (4-sided) roof that’s more architecturally interesting than a standard gable. Hipped roofs cost 15–25% more in trusses and metal but are visually distinctive.
• Detached studio / office: 900 sf is enough for a generous home office, art studio, or gym with separate bathroom. Common use for ADU-eligible properties.

Concrete Slab Options for 30×30

A 30x30 slab (900 sf) costs $5,000–$8,500:

Slab Type	Cost	Best For
4” slab, wire mesh	$5,000–$6,500	Light vehicles, hobby use, storage
6” slab, rebar reinforced	$6,500–$8,500	Trucks, daily workshop use

For a hipped-roof building, plan for slightly more reinforcement around the corner columns where the hipped truss converges loads at corner points.

How to Maximize a 30×30

• Square footprint = symmetric layout flexibility. Unlike rectangular buildings where one wall is the “front,” a 30x30 lets you put the door on any side without aesthetic compromise. Plan door placement around your driveway approach and lot orientation, not building geometry.
• Hipped roof is worth considering. A 30x30 with a hipped roof (4 sloped sides instead of 2) looks dramatically more residential and is often the difference between “shed” and “carriage house” in resale appeal. Adds $2,500–$5,000 to truss/metal cost.
• One large door, not two small ones. A single 16x8 overhead door on the front wall is more flexible than two 9x8 doors and costs less. Drive-through capability with the man-door at the back wall is a power-user move.
• Center the workshop, not the vehicles. Put your workbench/tool wall on a long uninterrupted wall (the wall opposite the overhead door), with vehicles on either side. Maximizes usable workshop depth and keeps tools out of the path of vehicle access.

Frequently Asked Questions

How much does a 30x30 pole barn cost?

A contractor-built 30x30 shell costs $14,000–$23,000 in 2026. With concrete slab: $20,000–$30,000. Fully finished: $32,000–$45,000. A kit alone runs $7,500–$13,000.

Is a 30x30 big enough for a 2-car garage and workshop?

Yes — comfortably. With two 9x8 doors taking up the front wall, you have 30 feet of depth. Park two vehicles in 22 feet, leave 8 feet of workshop depth on the back wall. Tighter than ideal, but functional.

Can I DIY a 30x30 pole barn?

Yes. The 30-foot truss span requires more equipment than a 24-foot span — most DIY builders use a tractor with a front-loader bucket to lift trusses, or rent a small forklift. Plan 4–5 weekends with two experienced people, or 3 weekends with a 4-person crew.

Why is a 30x30 sometimes more expensive than a 30x40 per square foot?

Because some fixed costs (site prep, mobilization, permits, engineered drawings) don’t scale with size. A 30x40 spreads those fixed costs across 1,200 sf instead of 900 sf — making the per-square-foot cost lower despite the higher total cost.

Do I need a permit for a 30x30 pole barn?

Yes, in nearly every jurisdiction. At 900 sf, a 30x30 exceeds the no-permit threshold (typically 100–200 sf) in every state. Permit costs: $250–$2,000 depending on location and engineering requirements.
