New ADU laws reshape housing landscape and zoning rules

In a recent government meeting, officials discussed significant changes to accessory dwelling unit (ADU) laws, highlighting the evolving landscape of housing regulations aimed at increasing residential density. The conversation centered around the implications of new legislation, particularly Assembly Bill 1033, which allows for the separate sale of ADUs, effectively enabling homeowners to convey these units independently from the primary residence.

Historically, ADU regulations required homeowners to live on the property to rent out the units. However, recent amendments have eliminated this restriction, allowing for multiple ADUs on a single-family lot—potentially transforming these properties into de facto duplexes or triplexes. Under the new rules, homeowners can now have up to four units on their property, depending on the lot's configuration.

San Jose has already adopted an ordinance to implement this new law, with Berkeley following suit. The legislation is opt-in, meaning cities must actively choose to adopt it. Officials noted that if cities do not opt in, the state may eventually enforce the law by right, similar to previous housing regulations.

Commissioners expressed concerns about the potential for increased density in single-family neighborhoods and the implications for property values and community dynamics. The discussion also touched on the complexities of property tax assessments and the role of homeowners' associations (HOAs), which, under current law, cannot prevent the establishment of ADUs but may influence their sale.

The meeting underscored the ongoing challenges of addressing housing shortages and affordability in the region. While the new ADU laws aim to provide more housing options, officials acknowledged that they do not directly address homelessness but rather seek to diversify housing types and increase opportunities for homeownership.

As cities consider adopting these regulations, the conversation will continue to evolve, with officials committed to exploring the implications for local communities and the broader housing market.
