Impact analysis
No direct cost to taxpayers — it's a regulatory pause — but the outcome shapes how many homes could be built in existing neighborhoods.
Future housing developers get a clearer, faster path — and the city stays off the state's watch list.
Property owners and affordable-housing advocates who see the moratorium as limiting housing supply and state-law-permitted development.

City Council Meeting - Oct 13, 2026
State law now lets a single-family lot be subdivided into up to 10 lots, each with a home plus an ADU and junior ADU — as many as 30 units on one property. The city is buying time to write a permanent ban on those ADUs into its code while the moratorium blocks them. Residents concerned about neighborhood density and infrastructure strain are the intended beneficiaries; property owners hoping to build ADUs on SB 1123 lots will have to wait.
City Council and Successor Agency Meeting - Sep 22, 2026
The council was asked to impose a 45-day emergency freeze on accessory dwelling units on lots created under Senate Bill 1123, which allows up to 10-lot subdivisions in single-family zones. The city worries those lots could hold up to 30 units each, straining parking, traffic, fire access, sewers and water. Resolution 202663 would signal a desire to ban such ADUs permanently while staff studies the issue.
