Where California renovation rules stand
CDPH says it is working on renovation regulations connected to SB 1076 and a 2023 amendment. We describe that as pending, with no dates, and treat the EPA rule as the one in force here. Renovation rules do not replace Title 17, which still applies to lead hazards and to anything meant to remove paint for 20 years or more.
What affects the cost
The amount of painted surface disturbed, the number of rooms sealed off, whether windows are replaced, the extra cleaning and verification steps and how long the occupants need to stay out all affect cost. Testing first can limit precautions to the surfaces that need them.
In a remodel, the sequence is test, then plan. For the first part, see lead paint inspection and testing; lead paint window and door work covers replacement windows when those are part of the project. The homepage of Redwood City Lead Paint Removal lists the rest.
