GUSTINE — The Gustine City Council approved an ordinance amending its zoning code to comply with recent changes to California’s Accessory Dwelling Unit (ADU) laws during its Oct. 21 meeting.

The item was passed as part of the consent calendar, with Council member Sherri Marsigli abstaining from the vote.

The ordinance, known as Zoning Ordinance Amendment (ZOA) 2025-01, updates Chapter 4-44, Section 4-44-140 of the city’s Zoning and Subdivision Code. The changes reflect new mandates introduced by Senate Bill 1211 and Assembly Bill 2553, which further streamline the ADU approval process and limit local regulatory authority.

Senate Bill 1211, signed into law in September 2024, expands ADU capacity on multifamily lots, allowing up to eight detached units under certain conditions. It also prohibits cities from requiring replacement parking when garages or carports are converted to ADUs and mandates ministerial approval for qualifying projects to reduce permitting delays.

Assembly Bill 2553 complements SB 1211 by refining how cities apply development standards such as setbacks and height limits, while requiring clearer communication about application requirements and timelines. Under specific conditions, it also permits the separate sale of ADUs from the primary residence.

City staff said the update ensures Gustine’s ordinance remains in compliance with state law while preserving areas of local discretion where permitted. The action was found to be statutorily exempt from the California Environmental Quality Act under Section 21080.17 of the Public Resources Code.

The council previously introduced and waived the first reading of the ordinance at its Oct. 7 meeting, approving it 4-0 with one member absent. No additional amendments were made to the proposed language.
