An Act amending the act of July 31, 1968 (P.L.805, No.247), known as the Pennsylvania Municipalities Planning Code, in general provisions, further providing for definitions; and, in zoning, providing for accessory dwelling units and for public availability of public utility fees.

This bill amends Pennsylvania's Municipalities Planning Code to standardize rules for accessory dwelling units (ADUs), which are secondary living spaces on single-family lots. It requires municipalities to allow at least one ADU per lot and sets a maximum size of 1,250 square feet or the size of the main home, whichever is smaller. The legislation restricts local governments from imposing certain barriers, such as requiring owner occupancy, mandating specific exterior designs, or charging additional fees for parking and impact. Additionally, the bill defines key terms like "gross floor area" and ensures that having an ADU does not reclassify a property as multifamily housing.
