Accessory Dwelling Units: owner-occupant requirements.

Impact

If enacted, SB 9 would significantly impact existing laws related to land use and planning within California. Local agencies will be unable to impose owner-occupancy requirements, which critics believe have historically limited the usability of ADUs as rental units. Additionally, the bill prohibits localities from establishing specific parking standards for ADUs in various scenarios, including those near public transit. This aspect of the legislation aims to promote increased density in urban areas while addressing housing shortages, particularly in high-demand regions.

Summary

Senate Bill 9, introduced by Senator Arregun, seeks to amend the Government Code concerning accessory dwelling units (ADUs). The bill primarily aims to eliminate owner-occupant requirements imposed by local agencies when evaluating proposed accessory dwelling units on properties with existing single-family dwellings. Furthermore, it intends to restrict local agencies from enforcing additional standards that are not explicitly mentioned in current law, thereby facilitating the creation of ADUs across California. This amendment comes in response to the growing need for affordable housing options and the recognition that restrictive local regulations often hinder the development of ADUs.

Contention

Debate over SB 9 is likely to center around local control versus state mandates on housing policy. Proponents argue that the bill simplifies regulations that stifle the development of ADUs, thus providing homeowners with more freedom to utilize their properties for rental income and combat housing shortages. In contrast, opponents may express concerns regarding the loss of local control over land use, fearing that such measures could lead to increased density in residential neighborhoods without proper oversight. Additionally, discussions may arise about the implications for parking, infrastructure, and community character as the state encourages the proliferation of ADUs.
