6th Cycle Housing Element implementation
The county's annual housing progress report drew criticism that it's unclear what has actually been completed; planning staff promised a new public website tracking housing sites and programs within weeks.
ADU, SB 9 and additional residential accommodations ordinance update
The county is overhauling its rules for backyard homes and other additional housing — adding SB 9 units, raising ADU size caps to 1,600 sq ft, and treating mobile homes like regular houses. It goes beyond state minimums, but commissioners worry about parking (state law prevents local parking requirements) and strain on water, sewer, schools and public safety. It now goes to the Board of Supervisors, likely August 25.
