What is an ADU?

• An attached or detached residential dwelling unit that provides complete independent living facilities for one or more persons and is located on a lot with a proposed or existing primary dwelling. An ADU shall include permanent provisions for living, sleeping, eating, cooking, and sanitation.

 Junior Accessory Dwelling Unit (JADU)

• A unit contained entirely within the walls of a single-family residence and is no more than 500 square feet in size. A JADU requires owner-occupancy of the primary dwelling or the JADU. Before permit issuance, the City must be provided a copy of a recorded deed restriction which shall include: (i) restrictions on the size and attributes of the JADU; (ii) prohibition of the sale of the JADU separate from the primary dwelling; (iii) if the JADU unit or primary dwelling is rented, the term shall not be for a period of less than 30 days; (iv) requirement that either the JADU or the primary dwelling be occupied by the property owner; and (v) a statement that the deed restriction shall be enforced against future owners.

SB 9

Overview

California Senate Bill 9 (SB 9) became law in January of 2022. It amended Section 66452.6 and added Sections 65852.21 and 66411.7 of the California Government Code relating to land use and subdivisions. The new law’s purpose was to expand housing production in California by providing two new pathways for homeowners to create additional dwelling units. The first pathway allows homeowners to subdivide a qualifying lot in a single-family, residential zone into two lots and have up to two residential units on each of the new lots. The second pathway allows for additional residential units on lots that are not split. In both cases, the applications are subject to criteria, limitations, and design standards. Both pathways provide for up to four dwelling units on the original lot.

Under SB 9, local agencies must administratively approve SB 9 applications without discretionary review, in single-family residential zoning districts, subject to State-specified qualifications and limits. Cities can enforce objective zoning and design standards for new residential dwelling units.
