Dublin, CA Short-Term Rentals: Night Caps (2026)

Many California cities cap non-hosted STRs at a set number of rental nights per year (for example, 90 days). Dublin does not. Because the City has no dedicated short-term rental ordinance, there is no codified annual or monthly night cap on STR operation. The only durational rule in play is the definition of a "transient" in DMC Section 3.16.020 - a person occupying for 30 consecutive days or less - which determines when Transient Occupancy Tax applies, not how many nights per year a property may be rented. The separate 30-day-minimum rule for accessory units (DMC Chapter 8.80) is a floor on stay length for ADUs and JADUs, not an annual cap. As a result, a legally permitted Bed and Breakfast Inn in Dublin is not subject to a published citywide ceiling on rental nights. The practical limit, if any, on how often a particular home may be rented is whatever the Planning Commission writes into that property's Conditional Use Permit conditions. Operators seeking certainty on operating frequency should raise it during the CUP process, since any binding night limit would be permit-specific rather than a uniform rule.
