An Act relative to zoning

This bill amends Massachusetts zoning laws to streamline development processes and clarify local regulations. It allows construction under existing zoning rules for 24 months (or 3 years for special permits) if started within that timeframe, with specific rules for phased projects and site preparation. It also sets strict time limits for public hearings on permits (max 150 days) and requires automatic approval if authorities miss deadlines, while updating variance rules to prioritize housing production. The changes primarily affect developers, local zoning boards, and residents navigating land use approvals.
