Overview: Are Short-Term Rentals Allowed in Trinidad, CA?

Yes. Short-term rentals (STRs) are explicitly allowed in Trinidad, California, but they are subject to detailed local controls and caps to preserve neighborhood character, housing availability, and environmental resources. The City of Trinidad permits three categories of STRs—Full-time, Resident, and Homeshare—each with specific standards, limits, and licensing requirements. Additionally, because Trinidad is within Humboldt County, a county STR permit is required and imposes its own rules, standards, and caps. Investors must comply with both the City’s Short-Term Rental Ordinance (Ordinance 2016-03) and Humboldt County Code § 314-60, and are also subject to applicable California state requirements (e.g., transient occupancy tax collection and remittance).

How to Start a Short-Term Rental Business in Trinidad, CA

The licensing and operational landscape involves two regulatory layers—City of Trinidad and Humboldt County. In practice, many properties within Trinidad will need a City STR license (if operating as a Short-Term Rental under the City ordinance) and a County Short-Term Rental Permit for any STR operation under the County code. Use the steps below to initiate and operate compliantly.

1. Decide STR category and feasibility

• Full-time STR (City): A dwelling rented for fewer than 30 days, year-round, with City caps by zone.
• Resident STR (City): Owner’s primary residence, up to 59 nights per year.
• Homeshare STR (City): Owner rents up to one bedroom in their primary residence, and is present on-site between 10 p.m. and 7 a.m. while rented.
• Confirm that the dwelling is legally established and located in a zoning district where STRs are permitted under City standards (City limits: UR/SR caps; other zones may not have caps but must meet location and density standards). For County permits, confirm the zoning allows residential use and that the STR is not prohibited by County provisions (e.g., ADUs permitted after 1/1/2020, SB9 lots, certain recorded affordability restrictions).

2. Apply for a City STR License (if operating within City ordinance limits)

• Initial application to the City includes: site/floor plans to scale; sample rental agreement and Good Neighbor Contract; proof of $1 million general liability insurance; evidence of primary residence for Homeshare/Resident STR applications; inspection by the Building Inspector prior to issuance; designation of a Local Contact Person (LCP) within 20 miles able to respond in 30 minutes; posting a 24-hour contact number inside the STR.
• City posts STR license information on its website and notifies neighbors within 300 feet.
• Licenses must be renewed annually by February 1. If you receive a license after October 1, renewal is due the following February.

3. Apply for a County STR Permit (required for all STR operations countywide)

• Prepare a complete application (materials are in addition to basic permit filing requirements).
• County permit types:
  • Administrative Permit: Standard compliance with all applicable standards.
  • Special Permit: Required for exceptions (e.g., access below Category 3; occupancy above formula; certain parking standards) and must meet specific findings.
• Maintain a posted Good Neighbor Guide for tenants and file an affidavit confirming distribution to neighbors (within 300 feet “as the crow flies” and nearest five along access roads).

4. Taxes and business compliance

• Register and remit Transient Occupancy Tax (TOT) to the City (City TOT registration and compliance are mandated).
• Register with the County if the County levies a TOT or other required taxes for STR operations.

5. Operational requirements

• Post emergency preparedness information (earthquakes, tsunami siren testing, fire department siren), keep a guest registry with names and vehicle plates, enforce occupancy, parking, and noise limits, and maintain septic/water use records consistent with City standards.

6. Renewal and maintenance

• City license renewals are due February 1. County permits lapse after two years unless you submit a statement of continued operation, proof of hosting stays, no outstanding violations or taxes, and pay a review fee.
• Monitor your property’s compliance status; repeated significant violations or failure to respond to complaints can result in fines, placement on a watch list, and license revocation.
