Accessory Dwelling Units (ADU) - Legislation AB 68
ADU's in your backyard? Yes AB 68 made it easier in 2019. If your neighbor has put a couple of these in your viewshed and they are ugly ( my neighbor did) well, that stinks. However, if your looking for a place to put Auntie Jane, well then, this is good news for you.
AB 68 streamlined the ADU process for local government entities. Specifically, there are no minimim size lot requirements and permits must be approved or denied within 120 days, whoop! What else? ADU's can be any size, there are ore details, like the primary home needs to have a certificate of occupancy, but that might not apply to you.
