SB 1077: ADU Guidance Development

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.

Public Input

The California Coastal Commission is soliciting feedback from local governments on their experiences permitting ADUs in the coastal zone and on what specific topics would be helpful for the Commission and HCD to include in the guidance. Given that guidance is intended to result in LCP policies that also clarify and simplify the ADU permitting process for property owners and builders, this opportunity to provide feedback is also open to members of the public to share their experiences with ADU development in the coastal zone. Your input will inform the guidance the Coastal Commission and HCD are preparing to comply with Senate Bill 1077.
