Solano County, CA Short-Term Rentals: Taxes & Fees (2026)

Under the Solano County Code, an operator renting property in the unincorporated area for 30 days or less must collect Transient Occupancy Tax (TOT) from each guest at the time of payment. The current rate is 5% of the rent. Chapter 11-20(a) of the County Code defines the rental properties subject to TOT, and the operator must hold a Transient Occupancy Registration Certificate, which must be posted in a prominent place on the premises. TOT is remitted quarterly: the return and payment are due within one calendar month of the close of each reporting period - October 31 (Jul-Sep), January 31 (Oct-Dec), April 30 (Jan-Mar), and July 31 (Apr-Jun). To be timely, payment must be received or USPS-postmarked by the due date; late payments incur penalties and interest under Solano County Code Chapter 11-26. Beyond TOT, operators pay a Solano County business license fee and the planning-permit application fee (Administrative Permit for hosted rentals, Minor Use Permit for VHRs). Note: as of 2026 the Board of Supervisors has discussed placing a measure on the November 2026 ballot to raise the unincorporated TOT rate above 5%; any increase would require voter approval and is not yet in effect.
