Common Uses
At 600 square feet, here's what fits in a 20x30
Wide-open interiors and the lowest cost per square foot in the business mean a Keen's 20x30 works as hard as you do. These are the setups our specialists see most often.
Vehicle & Toy Parking
Covers cars, a truck, ATVs, mowers and yard toys. Tall wall options give clearance for a lifted truck or dually.
Backyard Workshop
Room for a woodworking or mechanic's bench with the open sides keeping air moving. Add panels later to close it in.
Equipment & Mower Storage
Keeps tractors, zero-turns, motorcycles and tools out of the sun and rain with easy drive-in access.
Hay, Feed & Livestock
A classic small run-in shelter or hay cover. The Galvalume roof and treated posts shrug off Southeast humidity.
RV, Boat & Trailer Cover
Choose a 12-20 ft height and shelter a boat, camper or small RV with clearance for vents and AC units.
Hobby, Studio & Side Business
Detailing bay, market stand, pottery or art studio, or a shaded work area you can grow with lean-tos.

Frequently Asked
20x30 pole barn questions, answered
How much does a 20x30 open pole barn cost?
Pricing on the 20x30 depends on your wall height (10 to 20 ft), 6x6 vs 8x8 posts, and add-ons like windows, walk doors, roll-up doors and a 26-gauge upgrade, plus whether you choose a DIY kit or professional installation. Call 386-339-1676 for a firm, out-the-door quote in your county. Every installed barn qualifies for $0-down financing or rent-to-own with no credit check.
Should I choose 6x6 or 8x8 posts?
6x6 pressure-treated posts are our standard, most economical choice and are available up to 14 ft. For 16 ft and taller, or for heavier-duty use, we build with 8x8 posts for greater load and uplift capacity. Your specialist can recommend the right post size for your height and how you'll use the barn.
What's included with a 20x30 open pole barn from Keen's?
Every 20x30 ships as a complete open post-frame building: 6x6 or 8x8 pressure-treated posts, engineered steel or metal-web trusses, a Galvalume metal roof at a 3/12 pitch, all framing and fasteners, and stamped, certified engineered plans for permitting. Installed orders in FL and GA are set up on your prepared site by our own crews; delivery is quoted by distance.
What can you fit in a 20x30 pole barn?
At 600 square feet, the 20x30 fits two vehicles, a workshop, a tractor or ATV with room to work, or hay and livestock shelter. Tell us how you'll use it and we'll help you spec the right height, posts and door layout.
What heights does the 20x30 pole barn come in?
Choose from 10, 12, 14, 16, 18 or 20 foot eave heights. Lower heights suit garages and workshops; 14 ft and up gives clearance for RVs, boats and tall equipment. Select your height in the options above.
Should I buy the DIY kit or have it installed?
A DIY kit ships pre-cut with all hardware and instructions to 13 Southeast states and usually saves 15 to 25 percent. Professional installation is available in Florida and Georgia, where our crews set the whole building. Delivery is quoted by distance to your site.
Do I need a permit for a 20x30 pole barn?
Most counties require a permit for a structure over 200 square feet, and a 20x30 is 600 square feet. Keen's provides stamped engineered plans sealed by a licensed Florida Professional Engineer with every pole barn, which is what your building department needs. Your specialist can help coordinate the submission.
How is the building engineered for wind and weather?
Keen's pole barns are engineered and certified to meet or exceed 150 MPH wind loads with posts set on 12-foot centers as standard (10-foot centers available as an upgrade). The Galvalume roof carries a 40-year paint warranty and resists Southeast humidity and salt air.
Can I add sides or close in a 20x30 pole barn?
Yes. The 20x30 is an open building by default, but you can add partial or full side panels, end walls, lean-tos, and walk or roll-up doors. Configure it in the 3D designer or call 386-339-1676 and we'll price the closed-in version for you.
Does Keen's deliver and install in my state?
Professional installation is available anywhere in Florida and Georgia, with delivery quoted by distance to your site. DIY kits ship to 13 Southeast states: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, Virginia and West Virginia. Call 386-339-1676 to confirm coverage.
