Which codes and exemptions should I review?
Pennsylvania Uniform Construction Code (UCC), 34 Pa. Code Chapters 401-405 and referenced current ICC codes as adopted by Pennsylvania, including applicable 2021 ICC editions for 2026 permits. Mifflin County's Planning and Development Department administers the county Subdivision and Land Development Ordinance, while building permits and inspections are handled by local municipalities or certified third-party agencies. The Pennsylvania UCC requires a municipality or third-party agency to employ or contract with a Building Code Official; state Labor and Industry may serve where local authority is not provided. UCC exemptions are controlled by Pennsylvania law and the responsible municipality or Building Code Official. Emergency repairs or equipment replacements may proceed without a permit only when the application is submitted to the BCO within three business days. Agricultural buildings and certain utility or miscellaneous buildings may be outside portions of UCC coverage, but zoning, stormwater, sewage, floodplain, driveway, occupancy, and accessory-structure requirements vary locally.
