What is an ADU (Accessory Dwelling Unit) and a JADU (Junior Accessory Dwelling Unit)?
“Accessory dwelling unit” (also “ADU”) shall have the same meaning as set forth in California Government Code Section 65852.2, as amended from time to time. Generally, an accessory dwelling unit is 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 residential dwelling structure. It shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the primary residential dwelling structure is or will be situated. An accessory dwelling unit also includes an “efficiency unit” as defined in California Health and Safety Code Section 17958.1 and a “manufactured home” as defined in California Health and Safety Code Section 18007. An accessory dwelling unit may be created through: (i) construction of a new detached structure; (ii) construction of a new attached structure or addition; or (iii) conversion of existing permitted interior space within an existing dwelling, attached or detached garage, or accessory structure.
“Junior accessory dwelling unit” means a unit that is no more than 500 square feet in size and contained entirely within a single-family residence. A junior accessory dwelling unit may include separate sanitation facilities, or may share sanitation facilities with the existing structure.
State Assembly Bills 68, 881, 587, and 671, and Senate Bill 13 became effective January 1, 2020, amending Government Code Section 65852.2, thus revising regulations pertaining to the development of accessory dwelling units in residential and mixed-use zoning districts.
