Standby Generator permit in Pennsylvania

A permanently installed standby generator with automatic transfer switch and fuel connection. Here is the Pennsylvania-specific rule: who issues it, typical fees, timeline, go / no-go, and the official source to verify.

Verify locally. Pennsylvania's UCC is administered locally — over 90% of municipalities enforce it themselves, so permit thresholds and fees vary by city or township. Always verify with your local building department (e.g., Philadelphia L&I). Rules below are Pennsylvania-level guidance drawn from official sources — always confirm with the issuing building department before starting work. See the county permit authorities to find the right office.
