If you own property in unincorporated Humboldt County and have been running a short-term rental or thinking about starting one, the rules have continued to evolve. The county's STR Ordinance took effect in March 2024 and was amended in March 2025, with the Board of Supervisors voting to tighten several provisions beyond what planning staff originally recommended. Those amendments are now fully in effect for 2026, and they change the calculus for agricultural parcels, access roads, and neighborhood density in ways that matter for both current operators and prospective buyers.
Key Takeaways
- Humboldt County's STR Ordinance, adopted March 2024 and amended March 2025, is fully in effect for 2026 with tighter rules than the original draft proposed
- Agricultural parcels between 2.5 and 10 acres that are not operating as farm stays require a Special Permit
- A new 300-foot proximity rule means an STR cannot be located within 300 feet of another permitted STR
- STR permits are not transferable, and no permit will be issued on a parcel with active code violations
- Housing stock caps apply differently depending on location: 2% in the Greater Humboldt Bay Area (covering Trinidad-Westhaven, McKinleyville, Fieldbrook-Glendale, Blue Lake, Arcata, Jacoby Creek, Freshwater, Eureka, Fortuna, Hydesville-Carlotta, and Rio Dell-Scotia), 5% elsewhere in the county, and no cap at all in Shelter Cove
What the Ordinance Covers and What It Does Not
The ordinance applies to unincorporated areas of the county only. Properties within Eureka, Arcata, Fortuna, Blue Lake, or any other incorporated city operate under those cities' own rules.
A short-term rental is defined as a dwelling unit or portion thereof rented to guests for 30 consecutive days or fewer. The ordinance replaced the previous Vacation Rental Combining Zone provisions and Bed and Breakfast regulations. Existing B&B permits remain valid under their original approvals.
What the ordinance creates
- A two-tier structure: homeshares (owner present) and whole-unit rentals
- An Administrative Permit pathway for most qualifying STRs
- A Special Permit pathway for rentals seeking exceptions, those in resource zones, or those exceeding neighborhood concentration limits
- A Conditional Use Permit pathway, required specifically for whole dwelling unit STRs located within the Tsunami Hazard Zone of the Humboldt Bay Area Plan
- Performance standards covering health and safety, Good Neighbor Guide requirements, occupancy limits, and caretaker availability
- Housing stock caps in designated Community Plan Areas
The Three Permit Types
Administrative Permit
The faster, less expensive path with no public noticing or hearings required. To qualify, the STR must meet all operating standards without exceptions, fall within the housing stock cap, and be in a zone where residential use is permitted. Applications go through the county's Accela online permitting system.
Special Permit
Required when the STR seeks operational exceptions, sits on an Agriculture General parcel between 2.5 and 10 acres without a farm stay, would exceed the neighborhood concentration threshold, or is in a resource zone. The process involves neighbor noticing and a potential public hearing. Plan for several months of processing time.
Conditional Use Permit (Tsunami Hazard Zone)
Whole dwelling unit short-term rentals located within the Tsunami Hazard Zone of the Humboldt Bay Area Plan (which includes parts of the Samoa Peninsula and other low-lying coastal areas at risk of inundation from a Cascadia Subduction Zone earthquake) may only be permitted with a Conditional Use Permit. Approval requires specific findings: that the rental would not adversely impact the health, safety, and welfare of the community, and that it would not adversely affect the quality of the neighborhood.
What Every Application Requires
Required materials
- Current grant deed
- A completed Good Neighbor Guide delivered to all neighbors within 300 feet and the nearest five neighbors up and down the access road
- A signed affidavit confirming that delivery
- Evidence of property owner consent if the applicant is not the owner
- Compliance with all health and safety standards
- No active code violations on the parcel
The Good Neighbor Guide must name a caretaker who can respond to complaints and reach the property in a timely manner. It must also be physically present in the unit whenever guests are staying.
What Changed in the March 2025 Amendments
Three provisions were amended, and the Board adopted stricter language than staff had recommended on two of them.
The three amended provisions
- Agricultural parcels: The original ordinance restricted STRs on ag-zoned land to farm stays. The 2025 amendment created some flexibility, but the Board rejected a broad exception for parcels under five acres. Agricultural parcels between 2.5 and 10 acres that are not operating as farm stays now require a Special Permit. Owners of ag-zoned land should confirm acreage and zone before assuming they qualify for the simpler path.
- Neighborhood concentration: The prior ordinance measured concentration as a percentage of housing units. The 2025 amendment added a physical proximity standard: a proposed STR may not be within 300 feet of an existing permitted STR, measured as the crow flies. Properties in areas with established STR activity, particularly coastal and rural communities, need to verify this before applying.
- Access road standard: The prior rule required access via a Category 3 paved road with a 16-foot minimum width. The amendment now allows the "functional equivalent" of a Category 3 road, which benefits rural properties that meet the practical safety standard without precise technical conformance.
The Coastal Zone Has Its Own Version of the Ordinance
Properties within the California Coastal Zone (including much of the area around Trinidad and the North Coast) are governed by a separate, certified Coastal version of the ordinance rather than the inland rules. The coastal ordinance closely mirrors the inland structure, including the two-tier permit system and housing stock caps, but carries its own timing requirements and additional standards tied to coastal access and resource protection. The coastal ordinance required certification by the California Coastal Commission before taking effect, which followed a longer timeline than the inland version.
Housing Stock Caps
Housing stock caps vary by area, and confirming which cap applies is one of the most important steps before purchasing or investing in a parcel for STR use.
- In the Greater Humboldt Bay Area — covering Trinidad-Westhaven, McKinleyville, Fieldbrook-Glendale, Blue Lake, Arcata, Jacoby Creek, Freshwater, Eureka, Fortuna, Hydesville-Carlotta, and Rio Dell-Scotia — no more than 2% of overall housing stock may operate as permitted STRs. The cap applies at both the area level and within individual Community Plan Areas.
- Outside the Greater Humboldt Bay Area, the cap is 5% of overall housing stock.
- Shelter Cove carries its own separate cap status and currently has no limit.
- Farm stays and properties on local, state, or federal historic registries are exempt from the caps entirely.
- When a Community Plan Area hits its cap, no new permits can be issued until existing ones lapse or are revoked.
Confirm current cap availability with the Planning and Building Department before purchasing or investing.
Permits Are Not Transferable
STR permits do not transfer with the property. If you buy a home currently operating as a licensed STR, you cannot assume the previous owner's permit. You must apply for your own, confirm the property still falls within the housing stock cap, verify the 300-foot proximity rule, and receive a new permit before operating.
FAQs
Can I list on Airbnb or VRBO while my permit application is pending?
No. A valid permit must be in hand before advertising or operating. Listing before a permit is issued is a violation and can result in fines and denial of the pending application.
What about STRs that were operating before the ordinance?
Operators with documented evidence of operation prior to October 26, 2023 were given priority during the initial application window. Those who did not apply and are still operating without a permit are subject to enforcement. Legacy B&B permits remain valid under their original terms.
Does the ordinance apply to the coastal zone?
Yes, under a separate certified Coastal Zone version of the ordinance. Coastal Zone properties, including those near Trinidad and the North Coast, are subject to additional standards related to coastal access and resource protection.
Work With Someone Who Knows the Rules
The STR permitting process in Humboldt County is manageable with the right preparation, but the 2025 amendments added real complexity for agricultural parcels and areas with existing STR activity. The Land Man Office works with property owners and buyers throughout unincorporated Humboldt County.
