A bill for an act relating to county and city regulation of accessory dwelling units.(See SF 2369.)
The provisions of SSB3070 could significantly reshape local housing policies by reducing the restrictions historically imposed on accessory dwelling units. By mandating permissions, the bill may encourage the construction of ADUs as solutions to housing shortages. However, it is also crucial to note that this legislation alters the way existing historical building codes apply, especially regarding properties in designated historic districts, balancing development needs with preservation goals.
SSB3070 seeks to amend existing Iowa laws regarding the regulation of accessory dwelling units (ADUs) by counties and cities. The bill requires that local governments permit at least one ADU on lots occupied by single-family residences, expanding access and potentially increasing housing options in residential areas. Key stipulations include that the ADU must be compliant with building regulations, and its size must not exceed either 1,000 square feet or 50% of the primary dwelling's size, whichever is larger. Additionally, the bill proposes that unfinished basements will not count toward the size restrictions of an ADU.
Among the points of contention raised during discussions surrounding SSB3070 is the potential conflict between promoting housing availability and preserving the character of historic districts. Opponents of the bill argue that relaxing restrictions may lead to unsuitable developments in areas of historical significance, impacting the aesthetic and cultural identities of communities. They contend that the power to determine suitability of ADUs in these districts should remain with local authorities rather than being dictated by state law. This aspect of the bill exemplifies the ongoing tension between housing development and local control.
