AB 559 – Clearer Rules for ADU Construction
AB 559 strengthens consumer protections for homeowners working with ADU contractors. With clearer rules and accountability, building an ADU just got a little safer and a lot simpler.
It places ADU construction under the definition of “home improvement” in state law, triggering oversight that protects homeowners from bad actors. This change builds trust and confidence in ADU projects statewide.
