Union City has not adopted an annual night cap limiting how many days a property can be rented short-term. The only duration rule is the 30-day TOT threshold and the ADU minimum 30-day rental term in Section 18.32.020(M).
No ordinance limits the number of nights per year a Union City property may be offered as a short-term rental. The city's duration-related rules are different in nature: Transient Occupancy Tax applies to stays up to the first 30 days under UCMC Chapter 3.18, and UCMC Section 18.32.020(M)(1)(c) prohibits renting an accessory dwelling unit for fewer than 30 days. Neither establishes a yearly cap on rental activity. Annual night limits (for example 90-day caps) cited in Airbnb-host guides are unverified and have no basis in the Union City Municipal Code.
Because no night cap exists, there is no cap-specific violation; however TOT applies to all stays up to 30 days and ADUs may not be rented for under 30 days, each enforceable under the relevant chapter.
