South Gate planning commission backs ADU code update, sends ordinance to council
Summary
The Planning Commission voted to accept a CEQA exemption and recommend that City Council adopt amendments to Chapter 11.43 of the South Gate Municipal Code to align local accessory dwelling unit rules with recent state law changes.
The South Gate Planning Commission voted unanimously on Aug. 17, 2025, to accept a California Environmental Quality Act exemption and recommend that the City Council adopt amendments to Chapter 11.43 of the South Gate Municipal Code governing accessory dwelling units and accessory structures.
The measure updates local rules to reflect changes in state law governing ADUs, including new definitions, changes to owner-occupancy requirements, provisions for separate conveyance of ADUs under a limited nonprofit program, and an allowance for multiple detached ADUs on multifamily parcels under certain conditions. Associate Planner Joshua Valdez presented the changes and recommended adoption of Resolution No. 2025-07, and staff said the amendment is ministerial and therefore exempt from CEQA under the ministerial-project guideline cited in the presentation.
The ordinance update incorporates several recent state bills cited in staff materials, described during the presentation as Assembly Bill 345, Senate Bill 897, Assembly Bill 976, Senate Bill 477 and Senate Bill 1211, and refers to consolidated state provisions (identified in the presentation as Government Code sections grouped under 66310–66342). Among the key changes discussed: removal of the owner-occupancy requirement for ADU applications submitted after Jan. 1, 2025; adding definitions for “qualified nonprofit corporation” and “qualified buyer” to allow separate conveyance of ADUs in limited nonprofit programs; permitting up to eight detached ADUs on multifamily parcels provided the number of ADUs does not exceed the number of existing units on the lot; and codifying existing planning practice allowing expansion of accessory structures up to 1,000 square feet in some single‑family cases.
Staff also explained limits on local fees. The draft code follows state constraints that generally prevent new impact fees on ADUs below specified sizes but preserve local connection and capacity charges when separate infrastructure is required. Valdez said local practice allows, but does not require, separate utility meters for ADUs; connection or infrastructure fees for new lines remain chargeable. The draft raises the allowed height for detached garages by two feet (from 10 to 12 feet) to better accommodate pitched roofs, a change staff said responds to applicant requests.
Commissioners asked for more outreach and clearer public materials. Several members said a study session or workshop would help the commission and the public better understand the mechanics, limits and practical effects of the state changes. Staff and the assistant city attorney said they could prepare a workshop and also produce clearer, nontechnical materials for the public and applicants.
Following discussion, the commission took one consolidated motion to accept the CEQA exemption and recommend adoption of the code amendments by the City Council. The roll call recorded the following yes votes: Commissioner Castaneda; Commissioner Osayeta; Commissioner Valenzuela; Vice Chair Prieto; Chairperson Ruiz. The motion passed.
The measure now proceeds to the City Council for consideration; staff indicated additional state changes could require further code updates in coming months and offered to return with educational materials and a study session for the commission and public.
