An Act amending Title 53 (Municipalities Generally) of the Pennsylvania Consolidated Statutes, in preemptions, providing for occupancy limits.

HB 2109 prohibits Pennsylvania local governments (like cities, towns, and counties) from setting household size limits based on familial relationships (such as parents with children or roommates). It allows occupancy limits only for verified health/safety standards (like building codes) or to comply with federal/state affordable housing program rules. The bill directly affects renters, homeowners, and local officials who previously enforced such restrictions. Key definitions clarify that "familial relationship" includes blood, marriage, adoption, or foster care ties, and "local government unit" covers all Pennsylvania municipalities. This bill takes effect 60 days after enactment.
