Iowa HSB618 regulates county and city rules on accessory dwelling units, allowing one per lot in certain districts.
Iowa HSB618 modifies regulations on accessory dwelling units (ADUs). It mandates that counties and cities allow at least one ADU on the same lot as a single-family residence in zoning districts where such residences are permitted. The bill specifies that ADUs must comply with building regulations and cannot exceed 1,000 square feet or 50% of the size of the primary residence, excluding unfinished basements. ADUs in historic districts are regulated only if deemed incongruous with historical aspects.
