Accessory Dwelling Units
In an effort to accelerate housing construction throughout California, the State legislature passed a series of laws to encourage Accessory Dwelling Units (ADUs) in single and multi-family neighborhoods. Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) are independent living facilities located on the same parcel as the primary unit, which may be occupied by extended family members or tenants.
The City's ADU Ordinance (Ordinance No. 2021-211) is consistent with State law while maintaining the fabric of our community. Below is more information about Accessory Dwelling Units and Junior Accessory Dwelling Units. For questions, please contact (949) 362-4300 or email Planning@cityoflagunaniguel.org.
What is an ADU?
Accessory Dwelling Units (ADUs) have gone by many names, including granny flats, in-law units, and secondary units. By definition, an ADU is a self-contained, additional housing unit, on a permanent foundation, that contains a kitchen, bathroom, and a place to sleep. ADUs range in size from 150 square feet for a studio to 1,000 square feet for a unit with multiple bedrooms.
What is a Junior ADU?
Like an ADU, a Junior Accessory Dwelling Unit (JADU) is an additional housing unit on a residential property. JADUs are limited to a maximum of 500 square feet in size and must be contained within the walls of an existing or proposed home. JADUs require an efficiency kitchen, and may share a bathroom with the main house or include their own bathroom.
