Senate Bill 1077 (Chapter 454, Statutes of 2024) requires the California Coastal Commission, by July 1, 2026, and in coordination with the Department of Housing and Community Development (HCD), to develop written guidance for local governments to facilitate the preparation of local coastal program (LCP) amendments that clarify and simplify the permitting process for accessory dwelling units (ADUs) and junior accessory dwelling units (JADUs) in the coastal zone. Coastal Commission and HCD staff are seeking feedback from local governments and the public on ways to improve the efficiency of ADU permitting procedures in the coastal zone to inform this guidance.
