Zoning & Permits
Pennsylvania requires residential building permits through the Pennsylvania Uniform Construction Code (UCC), administered by the Department of Labor & Industry. As of January 1, 2026, the state uses the 2021 ICC codes with amendments. Over 90% of municipalities enforce the UCC locally. Always verify requirements with your local building department.
Off-Grid & Rural Builds
For rural builds, on-lot septic systems are regulated under Pennsylvania's Act 537 Sewage Facilities Program. Permits are issued through local Sewage Enforcement Officers (SEOs) at your municipality or county health department. Contact your local agency for soil testing, system design approval, and permits.
Energy Code & Efficiency
Pennsylvania enforces energy efficiency standards as part of the UCC, adopting the International Energy Conservation Code (IECC). The Pennsylvania Housing Research Center provides training and resources on current energy code requirements. Requirements address insulation, HVAC efficiency, and building envelope standards.
Local Zoning Tools
Zoning in Pennsylvania is administered locally by municipalities under state law. Penn State Extension provides comprehensive planning and zoning guidance for Pennsylvania municipalities. Contact your local Planning Commission or Zoning Hearing Board for site-specific dimensional requirements and use regulations.
Tip
If you're unsure about your parcel's status—whether it requires septic approval through your local SEO, falls under specific zoning restrictions, or needs additional site work—contact your municipal building department or local Sewage Enforcement Officer directly. In Pennsylvania, counties like Philadelphia, Allegheny, Bucks, and rural municipalities across the state all enforce different local requirements. The resources above are a great place to start.
