Request an Ordinance
Although cities and counties are mandated to permit ADUs and JADUs, they are not required to adopt ADU and JADU ordinances. However, any city/county that does adopt an ADU ordinance, must submit the ordinance to HCD within 60 days.
Requests for adopted ADU ordinances may be submitted here:

HCD reviews draft ADU ordinances as well as proposals to explore and allow a variety of housing choices, including "movable" tiny homes (Placer County and the City of Los Angeles). Once reviewed, HCD sends an ADU Ordinance Review Letter.
Jurisdictions are required to provide a response letter to HCD within 30 days of HCD’s ADU Ordinance Review Letter. The spreadsheet indicates whether a response letter was received.
