From the Casita Coalition:

“On September 28th, California Governor Gavin Newsom signed a large slate of housing bills, including several bills focused on ADUs and small housing. Since California passed its by-right ADU legislation in 2017, eliminating the biggest barrier to ADU adoption in the state, a series of “next gen” barriers have cropped up, each of which makes it more difficult to build ADUs in some jurisdictions. Each of the four ADU-related bills passed this session and signed by the governor make an effort to address some of these secondary barriers, and bring ADUs within reach for more Californians.

Here, we break down each bill – what it does, who it helps, and how it affects California’s blossoming ADU industry.”
