An Act amending Title 53 (Municipalities Generally) of the Pennsylvania Consolidated Statutes, providing for multi-family housing zoning ordinances.

This bill amends Pennsylvania zoning laws to allow municipalities with over 5,000 residents in growing counties to permit multi-family housing, specifically duplexes, triplexes, and quadplexes, on lots where single-family homes are allowed. The legislation requires that rules for these smaller multi-unit buildings cannot be more restrictive than those for single-family homes, while also defining specific criteria for what constitutes each housing type. Localities can petition a county or regional planning agency to review proposed developments to ensure existing infrastructure can support them, potentially requiring developers to make necessary improvements. The act applies only to municipalities meeting specific population and growth thresholds and takes effect 180 days after passage.
