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 Accessort Dwelling Unit (JADU). Also, multi-family lots may now add one ADU per every four existing residential units, so long as they were legally established.

Property Requirements

Residential parcels will be approved to add up to 850 sqft for a one bedroom ADU or up to 1,000 sqft for a two bedroom ADU, regardless of the underlying zoning standards of the property. A Junior Accessort Dwelling Unit (JADU) is approved up to 500 sqft. According to Califronia Residential Code, the minimum size of any living unit is 150 sqft (including Accessory Dwelling Unit (ADU)s and Junior Accessort Dwelling Unit (JADU)s). ~ According To AB68

Types of ADUs Allowed

Attached ADU

An attached ADU is one that is attached to your house. Also know as Addition ADUs or “bump-out ADUs. These types of ADUs can be accessed from the primary house with a door in the connection point, but also can be independent of the main home.

Dettached ADU

A detached ADU is not connected to your primary house. The dwelling needs to be within your property setbacks and allowable building size (both height and square footage).

Junior ADU

Junior Accessory Dwelling Units (JADUs) are named this way because they are small (up to 500 square feet).

In California, the recent state bills AB68 and AB 881 permits both an ADU and a Junior ADU (JADU) on the same lot with a proposed or existing single-family dwelling. This means you can have two units on your lot: ADU, and JADU.
