City Council Updates ADU Ordinance to Align with State Regulations

The Fillmore Planning Commission meeting on July 16, 2025, focused on updating the city’s regulations regarding Accessory Dwelling Units (ADUs) to align with recent state laws. The proposed amendments aim to ensure that Fillmore's zoning code reflects the latest legal requirements and clarifications surrounding ADUs.

The discussion highlighted several key changes to the local ordinance, which has not been amended since 2020. The updates include clarifications on the maximum size for attached ADUs, the elimination of owner occupancy requirements for both primary homes and ADUs, and adjustments to height allowances for these units. Additionally, the amendments specify that utility service lines must be installed underground and revise definitions related to ADUs and tandem parking to comply with state law.

Notably, the revisions allow existing single-family homes to add detached ADUs, with a maximum of eight units permitted on a single lot. The changes also clarify that if a primary home does not have fire sprinklers, the newly constructed ADU will not require them either.

The Planning Commission confirmed that these updates do not constitute a development project and are therefore exempt from the California Environmental Quality Act (CEQA) review process. This decision reflects the city’s commitment to keeping its regulations current and facilitating the development of ADUs in Fillmore.

The meeting underscored the importance of adapting local laws to meet evolving state standards, ensuring that Fillmore remains compliant while addressing housing needs in the community.
