What Size Shed Needs a Permit in Pittsburgh
Whether you need a building permit for a shed in Pittsburgh usually comes down to size. In Pittsburgh, the cutoff is 120 square feet: a simple one-story shed at or under that size generally doesn’t need a building permit, while anything that exceeds it does. A popular 10x12 shed (120 sq ft) lands exactly on the limit — at that size it’s still exempt, but going any bigger triggers a permit. Larger sheds, and any shed with electrical, plumbing, or a permanent foundation, almost always need a permit regardless of footprint.
Building a Shed Without a Permit in Pittsburgh
Even when a shed is small enough to skip a building permit in Pittsburgh, “no permit” doesn’t mean “no rules.” A permit-exempt shed generally must stay at or under the 120-square-foot limit, sit on a non-permanent base (sheds on skids or a gravel pad are treated more leniently than those on a poured foundation), and have no electrical or plumbing run to it. Crucially, zoning setbacks still apply — your shed usually has to sit a minimum distance from property lines and other structures, and that holds even for a permit-free shed. Confirm both the size exemption and the setback distance with the Department of Permits, Licenses, and Inspections before you build.
