PA SB1239

Requires municipalities to approve multifamily, mixed-use, or adaptive reuse developments in nonresidential zones (office, retail, parking) when applicants have will-serve letters from municipal water and sewer systems.

Exempts qualifying developments from local zoning restrictions including minimum/maximum density requirements, lot size limits, mandatory setbacks greater than 10 feet or utility easements, and requirements for walls, fences, or non-public open space.

Limits parking requirements to one off-street space per residential unit plus ADA-required accessible spaces, with shared parking agreements permitted as an alternative.

Removes building height limits for developments containing restricted-affordable units (up to 120% area median income) or restricted-deeply-affordable units (up to 60% area median income) that would otherwise prevent adding units.

Takes effect 60 days after enactment and does not preempt the Pennsylvania Construction Code Act.
