Research notes

Requires ADUs by-right in single-family residential zones in subject jurisdictions. Cities cannot impose owner-occupancy requirements or design standards more restrictive than primary structure. Home-rule cities are still subject to this preemption per the bill's express statewide-concern declaration, though challenges are possible.
