Where California renovation rules stand
California’s SB 1076 directs the state to bring its lead-related construction program into line with the EPA renovation rule. CDPH says it is still working on those renovation regulations; until they take effect, the EPA rule and EPA firm certification apply. Separately, Title 17 already treats disturbing lead paint without containment as a lead hazard under state housing law, whoever does the work.
What affects the cost
Lead-safe work adds containment, protective gear, HEPA cleanup and the renovator’s cleaning check to a remodel. How many rooms are sealed, whether the house stays occupied, and whether you test first to clear some surfaces as lead-free all change how much of that is needed.
A test before demolition can take surfaces out of the lead-safe scope; see lead paint inspection and testing. New windows bring their own decisions, set out on lead paint window and door removal, and Chula Vista Lead Paint Removal links the rest.
