Dublin, CA Short-Term Rentals: Occupancy Limits (2026)

There is no fixed short-term rental occupancy formula (such as two guests per bedroom) written into the Dublin Municipal Code, because Dublin has not adopted an STR-specific ordinance. Instead, occupancy is controlled in two ways. First, the use is allowed only as a Bed and Breakfast Inn under a Conditional Use Permit (DMC 8.12, listed C/PC). The CUP process is discretionary, so the Planning Commission can - and typically does - attach conditions of approval tailored to the specific property, which may include a maximum number of guests or rooms based on the site, neighborhood compatibility, and available parking. Second, baseline occupancy is governed by the building and fire codes Dublin has adopted (the California Building, Residential, and Fire Codes), which limit lawful occupancy of a dwelling regardless of the rental arrangement. Prospective operators should expect any binding numeric guest cap to appear in their individual CUP conditions rather than in a published citywide STR limit. Because the regulatory path is a discretionary land-use permit rather than a registration with set numeric standards, intending hosts are directed to discuss anticipated occupancy with the Planning Division early in the CUP application.
