ADU and Urban Dwelling Unit Zoning Updates
Summary
A homeowner wants to build a 2,516-square-foot two-story house plus a 1,000-square-foot backyard ADU. The project was already continued once over design concerns, and the remaining fight was over an old, nonconforming front fence — commissioners insisted it be fixed or torn down.

San Gabriel City Council Meeting - Oct 20, 2026
The 508 Gerona appeal reopened the 'mansionization' debate: how big is too big when a two-story house goes into a street of one-and-a-half-story minimal traditional homes? Councilmembers signaled a coming review of the design guidelines and process.
San Gabriel City Council Meeting - Jul 7, 2026
Ordinances 728 and 729 bring the city code in line with new state law on ADUs and urban dwelling units — adopted 5-0 on consent.
San Gabriel City Council Meeting - Jun 16, 2026
New state laws force San Gabriel to allow more ADUs with less local control — up to eight detached ADUs on multifamily lots, no design review for qualifying ADUs, and relaxed demolition limits for urban lot splits. Councilmembers worried about neighborhood character and historic districts but acknowledged the city must comply.

San Gabriel City Council Meeting - Apr 21, 2026
State laws passed in 2024-25 require San Gabriel to update its rules for ADUs, junior ADUs and urban dwelling units. The hearing was continued to May 19 after the California Housing Defense Fund asked for changes — residents can weigh in then.
Planning Commission - Apr 13, 2026
A local designer asked the city to publish clear guidelines for building ADUs on multifamily properties, saying the code is geared toward single-family homes and lags state law on parking and second-story ADUs. An updated ordinance goes to the City Council next week.
Design Review Commission - Feb 23, 2026
A homeowner wants to build a 2,516-square-foot two-story house plus a 1,000-square-foot backyard ADU. The project was already continued once over design concerns, and the remaining fight was over an old, nonconforming front fence — commissioners insisted it be fixed or torn down.
Planning Commission - Feb 9, 2026
New state laws force changes to San Gabriel's ADU rules: up to 8 detached ADUs on multifamily lots, no owner-occupancy for junior ADUs, faster 15-day review, and new floor-area counting rules. An eleventh-hour critical letter will be analyzed before the council's final vote.
Planning Commission - Jan 12, 2026
