Unincorporated Alameda County does not currently impose a countywide annual night cap on short-term rentals, but individual cities and future county programs may limit un-hosted rentals to a set number of nights.
As of current adoption, the unincorporated area of Alameda County does not impose a countywide annual cap on the number of nights per year a property may be rented as a short-term rental. Hosts are instead regulated through general land use, tax (TOT), noise, and nuisance rules. However, several Alameda County cities, including Oakland and Berkeley, have adopted their own STR ordinances that distinguish between hosted rentals (owner present) and un-hosted rentals (whole-home) and may cap un-hosted rentals at a set number of nights per year. Any future unincorporated-area STR program could follow the same approach, commonly ranging from 60 to 180 un-hosted nights per year, with hosted rentals uncapped. Hosts should monitor the Alameda County Community Development Agency website for proposed STR regulations and confirm their exact city's cap if the property is incorporated. Violating a night cap can result in revocation of the STR registration and administrative fines.
