Note: Guerneville is an unincorporated community within Sonoma County; therefore, short‑term rental (vacation rental) operations are governed by Sonoma County rules and state law—there are no separate city‑specific regulations.

Overview: Are Short-Term Rentals Allowed in Guerneville?

Yes—whole‑home short‑term rentals (30 days or less) are allowed in Guerneville only if your property meets Sonoma County zoning eligibility and you obtain all required approvals. Eligibility depends primarily on the underlying zoning, septic capacity, and whether your property sits within a cap or exclusion zone.

How to Start a Short‑Term Rental Business in This Market

Follow Sonoma County’s sequential process:

1. Determine eligibility

• Check zoning using the County’s Official Zoning Database or Map Viewer.
• Confirm the property is not in an exclusion (X) zone or over‑concentrated cap zone.
• Validate septic capacity against the bedroom count; verify that the home is an existing single‑family residence.

2. Become a Certified Vacation Rental Property Manager

• All vacation rentals must use a Sonoma County‑certified property manager (owner or designated operator).
• Complete the certification process and maintain current contact information.

3. Obtain a Transient Vacation Rental (TVR) Permit (Zoning Permit)

• Submit a complete application and all required documents online.
• Submit fees per the current Project Review Fee Schedule.
• Your application must include a site plan, floor plan, septic capacity proof, and other documents (see “Required documents” below).

4. Secure a Transient Occupancy Tax (TOT) Number

• Register with the Auditor‑Controller‑Treasurer‑Tax Collector (ACTTC) to obtain your TOT number prior to issuing licenses.

5. Apply for the Annual Vacation Rental License

• Submit online after receiving the TVR permit and TOT number.
• Provide ownership verification, site plan, TOT certificate, certified property manager number, and TVR permit number.
• Pay required fees (monitoring and noticing).
• Licenses must be renewed annually.

Note on property transfers

• A property sale does not transfer the STR authorization; the new owner must obtain a new TVR permit to operate.

Specific Regulations for STRs (County and State)

Countywide Zoning Eligibility (summary)

• Allowed zones: Coastal Zone (permit rules differ), certain Agriculture Residential (AR), Rural Residential (RR), Planned Community Rural Residential (PCRR), existing single‑family homes in C2/LC/K districts, and certain Agricultural/Resource zones (LEA, DA, RRD).
• Prohibited zones: R1, R2, R3, lands under Williamson Act contracts, Land Intensive Agriculture (LIA), Accessory Dwelling Units (ADUs), Junior ADUs (JADUs), farmworker housing, temporary or non‑habitable structures (e.g., yurts, tiny homes on wheels).

Cap and Exclusion Zones

• The County has designated “Cap Combining Districts” at 5% of housing stock and “Exclusion (X) Combining Districts” where STRs are prohibited.
• Areas near Guerneville include Austin Creek near Guernewood and Fitch Mountain, where caps and exclusions limit new permits; capacity in cap zones has been reached, effectively pausing new permit issuance.
• Verify eligibility on the County’s interactive map.

State-Level Considerations (California)

• Transient Occupancy Tax (TOT): Collect and remit TOT; obtain your TOT number from the County.
• Fire safety and defensible space: Maintain defensible space per state/County guidelines; adhere to local fire restrictions.
• Health and safety: Follow all septic and environmental requirements to support the septic system’s permitted capacity.
• Ordinances and enforcement: County ordinances apply to STR operations; violations can result in enforcement and fines.

Hosted Rentals (Contrast)

• Definition: Rental of a single room/sleeping area in a single‑family home where the owner remains in residence.
• Regulated separately from vacation rentals; must meet performance standards for compatibility with surrounding uses.
