ADU rules in Penn Hills, PA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Pennsylvania has no statewide ADU mandate. Penn Hills does not appear to have a specific ADU-enabling ordinance. Accessory dwelling units in Penn Hills would require a zoning variance or special exception. PA UCC permits and inspections required for any new dwelling unit construction.
Unlike California and Connecticut, Pennsylvania has no statewide law requiring municipalities to allow ADUs. Whether Penn Hills permits accessory dwelling units depends entirely on the local zoning ordinance adopted under the PA Municipalities Planning Code (Act 247). Some municipalities allow ADUs by right, some by conditional use or special exception, and many do not address them. Where allowed, typical conditions include owner-occupancy of the principal dwelling, maximum size limits (often 800 to 1,000 sq ft), dedicated parking, and separate utility meters.
Unpermitted ADU: code enforcement, stop-work order. Zoning violation: $100 to $500/day. May require removal of unpermitted unit.
