Concerns development of accessory dwelling units.

This bill defines accessory dwelling units (ADUs) as second homes attached or detached from a single-family home, with limits of 1,200 square feet and independent living facilities. It requires municipalities to permit ADUs on single-family lots and prohibits local rules like mandatory passageways, parking minimums, occupant relationship requirements, or separate utility billing. The bill also prevents restrictions that would effectively block ADU construction while allowing local control over short-term rentals and building code compliance. It directly affects homeowners seeking to add ADUs and local governments managing zoning.
