Detached Garage vs. Pole Barn: Which to Build

Cost drivers, spans, finishes and resale considerations compared side by side.

Structure

A stick-framed garage carries load through closely spaced studs on a continuous foundation. A pole barn carries load through widely spaced treated columns, which is why it spans further for less money.

Cost

Per square foot, post-frame is usually cheaper at larger sizes because there is less foundation and fewer framing members. Below roughly 24 feet wide, the gap narrows considerably.

Appearance and resale

On a residential lot, a stick-framed garage with matching siding and shingles almost always reads better and appraises better. On acreage, a clean post-frame barn is entirely expected.

Finishing the interior

Stick framing accepts drywall, insulation and cabinetry directly. Post-frame needs added framing between girts before you can finish it the same way.

Doors and spans

Need a 16 or 18-foot overhead door and clear interior space? Post-frame handles it naturally. Need a tidy two-bay next to the house? Stick-framed garage.

Our usual advice

Inside the city, build a garage. On the farm, build post-frame. In between, decide by what the building has to look like from the road.
