Accessory Units and Junior Units

Effective January 24, 2017, Permit Sonoma is processing Accessory Units in accordance with the adopted urgency ordinance. View the updated application submittal requirements. Read more about fire sprinkler requirements.

In September 2016, the Governor signed two bills that change State housing law regulating Accessory Dwelling Units, formerly called second dwelling units. SB 1069 and AB 2299 remove barriers to Accessory Units to encourage creation of more affordable housing statewide. The Governor also signed a bill (AB 2406) establishing regulations to enable local jurisdictions to permit “Junior Accessory Dwelling Units.” Junior Units are very small living units created in an existing bedroom within a single-family dwelling.
