relative to multi-family residential development on commercially zoned land.

Updated the document header and title to indicate the bill has been adopted by both the House and Senate, replacing the previous 'As Amended by the Senate' label.

Changed the approval standard from a general allowance to 'by right' approval, ensuring municipalities cannot arbitrarily deny multi-family development on commercial land.

Simplified water infrastructure requirements by removing the mandate for specific water supply studies and well permits, replacing them with a requirement to develop water in accordance with existing state laws.

Explicitly required municipalities to provide exemptions for setbacks, height, and frontage for buildings undergoing adaptive reuse, reversing a House deletion that had removed this provision.

Streamlined the planning board's authority to deny applications by removing detailed criteria for traffic and water supply studies, focusing only on the ultimate ability to secure water and sewage disposal.

Replaced a mandatory requirement for multi-family development with a conditional allowance that depends on the local planning board's confirmation of adequate infrastructure.

Added specific criteria for the planning board to deny applications, including insufficient traffic capacity, inability to secure water sources, or inability to dispose of wastewater.

Changed the rules for converting existing structures, removing a broad exemption for zoning violations and replacing it with a rule that allows waivers only if the building is not altered to further violate dimensional requirements.

Changed the effective date of the act from June 30, 2026 to July 1, 2026.
