PA SB 1346: Lowering Housing Costs: Accessory Dwelling Unit Reform
PA SB 1346 proposes to reform accessory dwelling unit (ADU) regulations, potentially increasing housing supply but also imposing new requirements on landlords. The bill aims to lower housing costs by easing ADU construction, which may affect rental property management, zoning compliance, and tenant screening practices.
