What are the ADU Rules in Los Gatos?

Los Gatos ADU Rules:

In Los Gatos, an accessory dwelling unit (ADU) is defined as a detached or attached residential dwelling that shares the same parcel as an existing or proposed primary residence. To qualify as an ADU, the unit must include essential living spaces, such as areas for sleeping, a full kitchen, and a bathroom. ADUs also encompass efficiency units and manufactured homes.

Another option is the Junior Accessory Dwelling Unit (JADU), which is a smaller unit of no more than 500 square feet. A JADU must be fully contained within the existing or proposed single-family residence, which can include space in an attached garage.


Both ADUs and JADUs must meet the development standards and regulations outlined in Division 7 of Chapter 29 of the Town Code. For more details on these requirements, you can refer to the ADU regulations found on the official town website at www.losgatosca.gov/ADUregulations. Additionally, Santa Clara County has developed a resourceful website, www.aduscc.org, which offers guidance and tools to help homeowners through the process of adding an ADU to their property. This collaborative initiative includes input from all 16 jurisdictions within the county to streamline the ADU development process.
