Accessory Dwelling Units

ADUs

The City of Santee Planning and Building Department is available to help residents interested in Accessory Dwelling Units (ADUs). ADU’s include granny flats, in-law suites, second units and casitas. ADUs are experiencing a boost in popularity among homeowners. This is in part due to legislative changes that have made it easier and less expensive for homeowners to build such units on their property. 

ADUs provide independent living area, a place to live and sleep, with a kitchen, and their own bathroom on the same property with a primary residence. ADUs are intended as permanent housing solutions, and are not to be occupied as short-term rentals.

The County of San Diego has developed plans that have been designed and reviewed for compliance with the California Building Code and are provided at no cost to residents. These may be used as guidance as homeowners develop their floor plans and elevations. It will be up to the individual property owner to complete plans based upon their specific site and most recent code updates. Please see the pre-approved plans located at the bottom of this webpage.
