Accessory Dwelling Units (ADUs) & Junior Accessory Dwelling Units (JADUs)
What are ADUs/JADUs?
Accessory Dwelling Units (ADUs) are commonly known as granny flats, guest houses, or secondary dwelling units. ADUs can provide affordable housing options and flexibility for homeowners and families. Junior Accessory Dwelling Units (JADUs) are smaller versions of an ADU that exist within the existing habitable space of an existing single family residence. ADUs/JADUs include cooking facilities to allow for independent living. As a reminder, short-term rentals are not permitted in the City of Temecula, including those in ADUs or JADUs.
