Common Uses
What fits in a 20x20 pole barn
At 400 square feet, the 20x20 is the sweet spot between a carport and a full barn. These are the setups our specialists see most often.
Two-Car Parking
Covers two full-size vehicles, or one vehicle plus a workbench and lawn gear. Add a taller wall height for a lifted truck or dually.
Backyard Workshop
Plenty of room for a woodworking or mechanic's shop. Add side panels and a walk door to close it in, or leave it open for ventilation.
Equipment & Toy Storage
Keeps tractors, ATVs, mowers, motorcycles, and yard tools out of the sun and rain. The open design means easy drive-in, drive-out access.
RV, Boat & Trailer Cover
Choose a 12 to 20 ft height and the 20x20 shelters a boat, camper, or RV. Tall eaves give you clearance for roof vents and AC units.
Hay, Feed & Livestock
An open 20x20 is a classic small hay barn or run-in shelter. The Galvalume roof and treated posts stand up to Southeast weather and humidity.
Hobby, Studio & Side Business
Detailing bay, pottery or art studio, market stand, or a shaded work area. Add lean-tos later as your needs grow.
Financing
Payment options on a 20x20 pole barn
The 20x20 open pole barn starts at $2,700 as a DIY kit or $4,220 installed. Spread it out with $0-down financing or rent-to-own with no credit check - your specialist builds the payment around your budget.

Frequently Asked
20x20 pole barn questions, answered
How much does a 20x20 pole barn cost?
A 20x20 open pole barn from Keen's starts at $2,700 as a DIY kit, or $4,220 fully installed in Florida and Georgia (10 ft height, 6x6 posts). Taller walls, 8x8 posts, side panels, lean-tos, color upgrades, and 26-gauge metal raise the price. Call 386-339-1676 for a firm, out-the-door quote in your area.
Should I choose 6x6 or 8x8 posts?
6x6 pressure-treated posts are our standard and most economical choice, available on the 20x20 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 20x20 pole barn from Keen's?
Every 20x20 ships as a complete open pole barn: 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 20x20 pole barn?
400 square feet covers two vehicles, a workshop, a tractor or ATV with room to work, a boat or small RV (with a taller height), or hay and livestock shelter. It's the ideal size when a carport is too small but a 30x40 is more than you need.
What heights does the 20x20 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 to see pricing.
Should I buy the DIY kit or have it installed?
A DIY kit ships pre-cut with all hardware and instructions to 14 Southeast states and usually saves 15 to 25 percent. Professional installation is available in Florida and Georgia, where our crews set the whole building, often in a single day. Delivery is quoted by distance to your site.
Do I need a permit for a 20x20 pole barn?
Most counties require a permit for a structure over 200 square feet, and a 20x20 is 400 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.
Can I add sides or close in a 20x20 pole barn?
Yes. The 20x20 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.
How is the 20x20 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 the humidity and salt air of the Southeast.
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 14 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.
