Relating to regulation of accessory dwelling units by political subdivisions.

HB 1779 prohibits local governments from imposing specific restrictions on accessory dwelling units (ADUs), which are secondary housing units on single-family or duplex lots. The bill bans requirements such as parking mandates, setbacks larger than five feet, impact fees for ADUs under 800 square feet, and size limits below 800 square feet or 50% of the main home. This directly affects property owners seeking to build or rent ADUs and local governments that create zoning rules. The law removes these common regulatory barriers without mandating new construction.
