Short-term rentals in unincorporated Contra Costa County pay a 10% Transient Occupancy Tax on stays of 30 days or less. Hosts must register with the county within 30 days of starting; Airbnb remits directly for its bookings, but direct bookings must be filed separately.
The tax side of running a short-term rental in unincorporated Contra Costa County centers on the Transient Occupancy Tax: 10% of rent on stays of 30 days or less, under Ordinance Chapter 64-10. Hosts must register with the county within 30 days of starting operations and obtain a certificate, even if a platform collects the tax. Airbnb remits directly for bookings made through its platform, but any direct bookings are the host's responsibility to file and remit. Late payment gets expensive — penalties of 10% then 20%, plus 1% monthly interest. Incorporated cities set their own rates.
Contact your local code enforcement office for specific penalty information.
