Short-Term Rental Investment Guide: Mendocino County, California

Executive Overview

Short-term rentals are allowed in Mendocino County, CA, but with significant regulatory caveats. As of 2025, comprehensive regulations are in place for coastal regions and the Town of Mendocino, while inland areas are currently governed by interim restrictions with a new comprehensive ordinance in development. Investors must carefully navigate county zoning distinctions between inland areas (Division I of Zoning Code) and coastal areas (Divisions II & III) to ensure compliance.

How to Start a Short-Term Rental Business in Mendocino County

Step 1: Determine Your Property Zone

Mendocino County has a unique regulatory structure where zoning determines applicable STR regulations:

Coastal Zones (regulated under existing ordinances):

• Division II: Coastal Zoning Code
• Division III: Mendocino Town Zoning Code

Inland Zone (under development):

• Division I: Inland Zoning Code

Critical Note: The inland zone begins at varying distances inland from the shore. Use the county's interactive map at mendocinocounty.gov to determine your exact zone classification.

Step 2: For Existing Operations (Pre-August 1, 2017)

If you operated a STR before the moratorium date of August 1, 2017:

1. Document Prior Operation: Provide evidence of legal operation to the Department of Planning and Building Services
2. Business License Application: Submit application after review and concurrence by Planning & Building Services
3. Zoning Compliance Review: Your property's zoning will be evaluated
4. Tax Compliance: Make payments to the Treasurer-Tax Collector if you hadn't been paying required taxes
5. Use Permit: May be required under existing zoning code

Step 3: For New Operations (Post-Moratorium)

Currently, new STR establishments are prohibited in both inland and coastal zones pending finalization of comprehensive regulations. This moratorium was established through Ordinance 4391 in August 2017.
