Sonoma, CA Short-Term Rentals: Registration Rules (2026)

Each step is mandatory. Step 1: pass the Certified Property Manager exam administered by Permit Sonoma — applicants self-certify on the property or designate a certified manager. Step 2: file the Zoning Permit (TVR) application online with a scaled site plan (bar scale, north arrow, all structures labeled), a floor plan showing each guestroom and exits, and documentation of septic capacity for systems serving more than 5 bedrooms. Step 3: complete the TOT registration form and submit to TOT@sonomacounty.gov or mail to 585 Fiscal Drive, Suite 100, Santa Rosa, CA 95403 to receive a TOT certificate number. Step 4: with the approved TVR permit and TOT number, file the annual Vacation Rental License online including ownership documentation (deed, title report, or trust certification) and the TOT certificate details. Step 5: license expires 365 days from approval and must be renewed annually via the online portal. All advertising must conform to the approved occupancy; under Sec. 26-88-120 advertising a property inconsistent with its approvals is itself a violation.
