An Act to promote Yes in My Back Yard

This bill allows municipalities to permit duplexes, triplexes, quadplexes, and townhomes (up to five units total) on residential lots without zoning restrictions, as long as reasonable regulations like site plans and setbacks don't make development infeasible. It also eliminates minimum parking requirements for new residential projects and establishes streamlined approval for "Missing-Middle Housing Subdivisions" (smaller residential lots, max 10,000 sq ft each). The bill directly affects homeowners, developers, and municipalities by expanding housing options on existing residential properties. Key provisions require local zoning to allow these housing types "as of right" and create standardized subdivision guidelines for smaller lots. The changes apply to areas with municipal water/sewer systems and take effect 365 days after enactment.
