Accessory Dwelling Units (ADUs) mandated by the State of California override local planning regulations to permit a second unit on almost any single-family zoned property. The law also allows any single-family zoned lot to be subdivided into two parcels. Additionally, it allows ADUs to be built with just a four-foot setback or no setback at the new interior property line of a subdivided parcel, in contrast with most towns, which have setbacks of more than 7 feet, up to 30 feet. It also mandates very relaxed parking requirements or no parking if the project is near public transit.
Is California paving the way for ADUs across the US?
