prohibiting certain municipal development restrictions.

Section III was expanded from allowing utilities only in 'perimeter buffer areas of subdivisions' to allowing them 'within or along any designated buffer areas, including but not limited to perimeter buffers, residential buffers, setbacks, and open space areas of a subdivision or lot.' This is a much broader range of protected areas where utilities can now be placed.

A new Section IV was added requiring municipalities to allow placement of utilities within wetland buffers or conservation areas by special exception or conditional use permit, subject to the same wetland and shoreland exclusions. This is a new category of area not covered in the House version.

The savings clause (now Section VI) changed 'and other state environmental laws' to 'or as otherwise required by state law,' broadening the range of state laws that can impose conditions beyond just environmental ones.

A new Section V was added prohibiting municipalities from imposing additional restrictions or requirements regarding building or lot size for affected properties before the effective date. This protects existing development rights from being retroactively restricted.

Section II now references NFPA standard 1141 in addition to state fire code as the benchmark for dead-end road lot caps, and changed 'within current zoning restrictions and requirements' to 'otherwise comply with current zoning restrictions or requirements,' making the compliance standard slightly less strict (or instead of and).

The effective date was moved from July 1, 2027 to April 1, 2027, bringing it forward by three months.

Section I removed the specific enumeration of fire code standards (life safety, property access, asset preservation, emergency vehicle access, roadway design) and now simply requires compliance with 'the state fire code' without listing components.

The prohibition on municipal numerical caps for housing lots on dead-end roads now only applies when the cap is 'greater or lower than any such cap adopted in state fire code.' Municipalities can still enforce lot caps that match the state fire code, which was not explicitly allowed before.

The bill no longer permits municipalities to place utilities within designated open space areas of subdivisions. That permission is now limited to perimeter buffer areas only, removing a broader right that existed in the introduced version.

The effective date changed from '60 days after its passage' (a relative date depending on when the bill becomes law) to a fixed date of July 1, 2027.
