Code Section 403.1, one-story residential accessory structures not exceeding 1,000 square feet are exempt from UCC building permits statewide. This baseline applies in every Pennsylvania municipality. Local zoning setbacks, permits, and design rules still apply, but the building-code permit threshold is preempted.

Constructing structures over the 1,000 sq ft threshold without UCC permits can result in stop-work orders, fines up to $1,000 per day per violation, and required removal.

Frequently Asked Questions

Do I need a building permit for a backyard shed in Pennsylvania?

Under the PA UCC, one-story residential sheds 1,000 square feet or smaller are exempt statewide from building permits. Local zoning permits and setback rules may still apply.

Can my borough require a UCC permit for a 200 sq ft shed?
