Union City has not adopted a primary-residence requirement for short-term rentals. No ordinance limits rentals to a host's primary home, though accessory dwelling units cannot be rented for fewer than 30 days under Section 18.32.020(M).
There is no Union City ordinance requiring that a short-term rental be the operator's primary residence. The Municipal Code does not condition rental registration or business licensing on owner-occupancy. The relevant restriction is on accessory dwelling units: UCMC Section 18.32.020(M)(1)(c) states that accessory dwelling units shall not be rented out for a period of less than 30 days, consistent with California Government Code Section 66323. That means a backyard ADU cannot be used as a short-stay rental, but a primary single-family home or permitted boarding arrangement is not barred by any primary-residence rule. Primary-residence caps cited by some Airbnb-host blogs are unverified and not in the Union City code.
Renting an accessory dwelling unit for fewer than 30 days violates UCMC Section 18.32.020(M) and state ADU law, subject to zoning enforcement by the Community Development Department.
