Dublin, CA Short-Term Rentals: Primary-Residence-Only Rule (2026)

Dublin has not adopted a rule that limits short-term rentals to a host's primary residence in general. However, the City effectively channels STRs to the principal dwelling by prohibiting STR use of secondary units. The Short Term Rental program page states that accessory dwelling units (ADUs) and junior accessory dwelling units (JADUs) are prohibited from being rented for less than 30 days, which prohibits using them as STRs (the page cites DMC 8.80). In the current Dublin Municipal Code Chapter 8.80, the accessory dwelling unit regulations provide, "No Short-Term Rental. Accessory dwelling units shall not be rented for terms of 30 days or less," and the junior ADU regulations provide, "No Short-Term Rental. Junior accessory dwelling units shall not be rented for terms of 30 days or less" (these provisions were adopted by Ord. 9-25 in November 2025). This mirrors California state law, which under Government Code Section 66314 requires that ADUs not be rented for terms shorter than 30 days. The practical effect is that a Dublin STR must be in the primary home (operated under a Bed and Breakfast Inn Conditional Use Permit), and a homeowner cannot convert a backyard ADU or in-law JADU into an Airbnb. Hosts should confirm whether their unit is classified as an ADU or JADU, because that classification triggers the absolute 30-day-minimum rental floor.
