This bill amends existing laws regarding accessory dwelling units (ADUs) by establishing specific provisions for their allowance in various zoning districts, particularly focusing on the protected shoreland areas. The bill stipulates that municipalities must allow one ADU as a matter of right in all zoning districts that permit single-family dwellings, with the exception of the protected shoreland district. In this district, ADUs may be permitted either as a matter of right or through a conditional use permit or special exception, giving municipalities the discretion to allow detached units while ensuring compliance with relevant regulations.

Key changes include the insertion of language that clarifies the conditions under which ADUs can be permitted in the protected shoreland, specifically stating that municipalities are not required to allow detached units but may do so if they meet local ordinances. Additionally, the bill specifies that detached ADUs are permitted outside the protected shoreland, reinforcing the requirement for compliance with existing municipal regulations. The effective date for these changes is set for July 1, 2026.
