Shed Installation · Union County, Pennsylvania
In Union County, a Shed Installation under 200 sq ft generally does not require a building permit. At or above 200 sq ft, a permit is required.
Municipalities can opt out of enforcing the state code. Building permits in Union County are handled under the Statewide (opt-in) building code (IRC 2021). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Union Building Inspector.

Permits for sheds often depend on square footage and whether the structure is permanent.
With a population of around 42,456 residents, Union County generally runs a more streamlined permitting process than major urban hubs.
Because of severe winter weather in Pennsylvania, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Pennsylvania Uniform Construction Code.
Regardless of the state permit rule above, Union County still enforces property-line setbacks and local zoning for your Shed Installation. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Union Building Inspector before building.
Pennsylvania requires local zoning to be consistent with a municipal comprehensive plan, often resulting in multi-municipal cooperative zoning agreements. Fortunately, Pennsylvania maintains relatively builder-friendly regulations, keeping base permit fees competitive.
