Wei Chen
Wei Chen covers Bay Area permits, planning, ADU development, and code compliance for 9Builders. He translates the thicket of California and municipal building regulations — SB-9, AB-68, JADU rules, coastal commission requirements, and San Francisco unique permit process — into actionable steps for homeowners. Wei has followed California ADU reforms since 2017 and researches current planning department timelines, fee schedules, and approval requirements across Santa Clara, San Mateo, Alameda, and Contra Costa counties. His guides also cover how to work through code violation notices and bring older homes up to current standards without triggering unintended triggers for mandatory retrofit work.
