Number of ADUs allowed:

According to state law, all single-family homes are allowed at least one Accessory Dwelling Unit (ADU). Additionally, single-family lots which are owner-occupied may create one Accessory Dwelling Unit (ADU) and one Junior ADU. Also, multi-family lots may now add one ADU per every four existing residential units, so long as they were legally established.

Types of ADUs allowed:

Detached ADU, Attached ADU, Junior ADU are approved. Accessory Dwelling Units may be new construction or converted from existing space. JADUs must be converted from existing space.

Lot size:

Residential properties will not be subject to any minimum lot size for Accessory Dwelling Unit (ADU)s by ordinance or of the underlying zoning district. ~ AB68

ADU size:

Residential properties will be allowed to build up to 850 sq.ft. for a one bedroom ADU or up to 1,000 sq.ft. for a two bedroom ADU, regardless of the underlying zoning standards of the property. A JADU is allowed up to 500 sq.ft.. According to California Residential Code, the minimum size of any living unit is 150 sq.ft. (including ADUs and JADUs). ~ Updated: State Law AB-68

Setbacks:

The maximum required setback for a detached new construction Accessory Dwelling Unit shall be no more than 4 ft from the rear and side property lines. Setbacks will not be required for Accessory Dwelling Units and Junior Accessory Dwelling Units converted from existing space that was legally eastablished. Attached Accessory Dwelling Units and conversions from existing space to be expanded will be required to comply with the setbacks of the underlying zone. ~ AB68

Parking:

Lots which convert an existing garage to an Accessory Dwelling Unit (ADU) or JADU will not be subject to replacement parking requirements. ~ AB68 & AB881 Update

Fire Safety:

Accessory dwelling units shall not be required to provide fire sprinklers unless they are also required for the primary dwelling. ~ State Standards

Shape, materials and style:

Specific design styles and restrictions are not specified under State Standards. Passageways shall not be required in conjunction with the construction of an accessory dwelling unit. ~ State Standards

Height:

The maximum height of an ADU is not specified in the state standards. If ADU maximum height is not established locally, the height limitations of the underlying zone shall apply. ~ State Standards

Design review:

The municipality shall provide a ministerial review process which is not based on a discretionary approval for an ADU. The process shall take no less than 120 days.

Number of Bedrooms:

No maximum number of bedrooms is established other than that implied by the maximum size of an ADU allowed. ~ State Standards

Ownership:

Between between 2020 and 2025, owner occupancy requirements will not apply to new Accessory Dwelling Units. (applicable to new construction and conversion units) ~ According To SB13

Utility connections:

Connection and utility fees shall be reasonable, and shall not be disproportionately higher than those to develop primary dwellings, so as not to deter the development of ADUs. If a private sewage disposal system is used, such as a septic system, review and approval by a local health officer may be required. ~ State Standards

Allowed Zones:

*** Beginning in 2020, according to state law, all residential zoning districts, including single-family and multi-family, are allowed to build Accessory Dwelling Units. ***
