Do you need a building permit in Pennsylvania?

Usually it depends on the size of the job, and the size that decides it is not set by Pennsylvania: permits are issued by the city or county, not the state, so the rule that governs your project is the one your own jurisdiction publishes. 11 of those local rules require a permit outright, 11 depend on a size or scope condition the office publishes, and 0 need none. Pennsylvania sets the building code those local rules derive from; your city or county sets the threshold and the fee.

Do Pennsylvania jurisdictions agree?

Every row below is a measurement at least two Pennsylvania jurisdictions publish, compared against each other. This is the question a statewide answer cannot settle, because the number that governs your project is the one your own city or county publishes.

Project Published threshold Jurisdictions Agreement
