HB2720 Summary

• Municipalities with populations over 75,000 must adopt regulations allowing at least one attached and one detached accessory dwelling unit as permitted uses on single-family residential lots, with an additional detached unit allowed on lots of one acre or more if at least one unit is a restricted-affordable dwelling unit.

• Municipalities are prohibited from requiring familial relationships between occupants, matching exterior design standards, additional parking, rear/side setbacks exceeding five feet, public street improvements, or restrictive covenants for accessory dwelling units.

• Municipalities may not restrict accessory dwelling unit height, setbacks, lot size, or coverage more than single-family dwellings in the same zone, and units are capped at 75 percent of the primary dwelling's gross floor area or 1,000 square feet, whichever is less.

• If a municipality fails to adopt required development regulations by January 1, 2025, accessory dwelling units become allowed without limits on all residential-zoned lots or parcels in that municipality.

• Adds requirement that owners of vacation rentals or short-term rentals in newly constructed accessory dwelling units must reside on the property, unless the property owner had the right to build an accessory dwelling unit before the effective date of this amendment.
