Sonoma prohibits renting any ADU or JADU for terms shorter than 30 days (no short-term/vacation rentals). Properties with an attached JADU are categorically ineligible for vacation rental use.
Under SMC 19.45.030, no ADU or JADU may be rented for a term shorter than 30 days. Sonoma classifies any sub-30-day rental as a short-term/vacation rental, which is incompatible with the ADU's purpose of providing long-term housing supply. The rule applies to all ADUs regardless of when permitted. Additionally, a property containing a permitted attached Junior ADU is wholly ineligible for vacation rental use - the primary dwelling on a JADU lot also cannot be operated as an STR. These restrictions are encoded in the deed restriction recorded at permit issuance and run with the land, binding successive owners. The rule is consistent with Cal. Gov. Code 65852.2(a)(6), which authorizes local agencies to prohibit ADU rentals shorter than 30 days.
Renting an ADU or JADU for less than 30 days violates both SMC 19.45.030 and the recorded deed restriction, exposing the owner to enforcement under SMC Ch. 1.28 (administrative citations) and SMC 19.45.090 (violations and enforcement). The city may also enforce the deed restriction through civil action. Sonoma's vacation rental program separately requires a permit; operating an unpermitted STR triggers additional citations. Repeat or willful violations can lead to escalating fines and revocation of any vacation rental permit on the property.
