Accessory Dwelling Units (ADU) ORDINANCE

ADU

All ADU applications must be submitted via email to CommDevInfo@sgch.org.

WHAT IS AN ACCESSORY DWELLING UNIT?

An accessory dwelling unit (ADU) is an attached or detached structure that provides independent living facilities for one or more persons and includes permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as a single-family dwelling unit. ADUs are sometimes referred to as secondary units, granny units, or in-law units. They can have a separate mailing address and be rented to a third-party or occupied by a property owner(s).  

A Junior ADU is a repurposed existing bedroom within a single-family home that incorporates a wet-bar kitchen and an exterior entrance. This creates a separate living space within the existing home that is connected, but private. 

On January 21, 2020 the City Council adopted new ADU regulations that apply to properties with single-family homes in all residential zones.  These new regulations went into effect on January 22, 2020.  Information from the City Council meetings can be found below:
