Do I Have Room in My Backyard for an ADU?
Prior to 2020, many California homeowners were restricted from building an accessory dwelling unit (ADU) in their backyards because of setback requirements in local city ordinances. For example, at my house in Fremont, the setback requirements were 25 feet from the rear boundary and 6 feet from the side boundary.
However, the new California ADU laws that went into effect on January 1, 2020 prohibit cities from having ADU setback requirements of more than 4 feet for both the rear and side yards. This allows homeowners to build a standalone ADU or an extension ADU as close as 4 feet from their property boundaries in the read and side yards. This change in the law makes it possible for many more property owners to add an ADU to their backyards!
