Sonoma County requires all vacation rental operators to use a certified property manager — self-management is not permitted. This unique requirement adds ongoing cost that investors must factor into pro forma calculations.
Sonoma County's vacation rental permit program, administered by Permit Sonoma, has a requirement found in few other U.S. jurisdictions: all vacation rental operators must designate a certified property manager who is responsible for the property's compliance. Self-management by the owner is not permitted under the current ordinance.
The certified property manager must be available 24 hours a day, 7 days a week to respond to complaints or issues related to the rental. For most owners, this means contracting with a licensed property management company that has staff on call. Verify that any manager you designate meets the county's certification requirements — the county maintains a list of criteria that must be met.
Professional property management in Sonoma County typically runs 20–30% of gross rental revenue. This is a meaningful ongoing cost that reduces net returns significantly. Factor this in when evaluating the economics of an STR investment in wine country.
Identify and contract with a property manager who meets Permit Sonoma's certification requirements before submitting your application. You'll need to provide their name, contact information, and certification documentation as part of the application.
Applications are submitted through the Permit Sonoma portal at permitsonoma.org. Required documents include proof of ownership, the certified property manager's information, insurance certificate, and occupancy details.
