Quirks & watch-items
Quirks & watch-items
- Most PA jurisdictions opt into the statewide UCC
- Philadelphia has its own custom building code
- Indiana, PA is a borough — different jurisdiction type
- PA UCC adopts 2018 I-Codes only (not 2021); 2021 accessibility provisions enjoined by Commonwealth Court Oct 26, 2022
- PA does NOT directly adopt NFPA 70 (NEC) at the UCC level — electrical code adoption is handled outside the UCC
- 2021 ICC code adoption process referenced in the "2021 icc code adoption final report.pdf" on pa.gov, but as of 2026-04-24 the 2018 I-Codes remain in force
