Iowa SSB3070 regulates county and city policies on accessory dwelling units, including size limits and conditions for historic districts.

Iowa SSB3070 amends regulations for accessory dwelling units (ADU) in counties and cities. It mandates that a minimum of one ADU be allowed on the same lot as a single-family residence in zoning districts where such residences are permitted. The ADU must comply with building regulations, not exceed 1,000 square feet or 50% of the size of the primary residence, excluding unfinished basements. For historic preservation districts, ADUs are regulated only if deemed incongruous with historical aspects, with reasons recorded.
