What the Law Requires in Humboldt County
On the Humboldt coast, the first question is whose rules apply, because a mailing address doesn't settle it. Unincorporated land, including McKinleyville, Westhaven, the Samoa Peninsula, Orick and much of the coast around Trinidad, follows the county's short-term rental ordinance; the cities of Trinidad, Arcata, Eureka and Ferndale set their own rules inside their limits; and in the coastal zone a coastal development permit can be part of the process. The lodging taxes are local too. Airbnb collects the county's 12 percent transient occupancy tax, cleaning fees included, on reservations of 30 nights or fewer in unincorporated Humboldt County, but its California page expressly leaves out the incorporated cities, Trinidad, Arcata, Eureka and Ferndale among them, and Eureka's own guidance says plainly that Airbnb and VRBO don't collect or pay the city's tax for you. Inside the cities the rates differ: Arcata's is 12 percent, 10 percent for the city and 2 percent for the Humboldt County Tourism Business Improvement District, and Eureka and Ferndale each charge 10 percent, with Ferndale adding the 2 percent district assessment only for operators with five or more units. State housing law adds a rule that reaches across jurisdictions: the county says an accessory dwelling unit or junior ADU permitted after December 31, 2019, can't get a short-term rental permit, and Eureka allows ADUs only if their certificate of occupancy came before January 1, 2020, and excludes homes created under the state's two-unit and urban lot-split provisions, Government Code sections 65852.21 and 66411.7.
On county land, the Board of Supervisors adopted the short-term rental ordinance on March 5, 2024, in an inland version (Humboldt County Code Section 314-60.05) and a coastal version (Section 313-61.05), and the county says both are now in effect. A short-term rental is an entire dwelling rented for 30 days or fewer, or two or fewer rooms rented with a host on site; farm stays that meet those terms count too. Most operators need an administrative permit, and a special permit is the route for some exceptions, such as an access road below the county standard or going past the neighborhood concentration limit in Section 314-60.05.10.6 where permitted rentals already exist. The adopted ordinance includes a cap on new permits, and the only percentages in this section come from the draft: when Jefferson Public Radio covered it in February 2024, it reported a two-year administrative permit and caps of 2 percent of the housing stock in the coastal Humboldt Bay area and 5 percent in the county's other community areas, with homeshares outside the cap. Treat those as the draft's numbers, not the adopted ones. The county said its cap evaluation data would be available after July 3, 2024, to show which areas can take new permits, so ask the Planning and Building Department where your area stands before you count on one. A rental offered for 60 consecutive days or fewer still needs a permit but is exempt from the cap, with evidence of the stays due at renewal, and renewals use the county's Statement of Continued Operation affidavit. The permit goes in the owner's name unless the owner's signed consent puts it in the operator's, an operator can apply as the owner's agent, and no individual or business may own more than three parcels with short-term rental permits.
The county's standards read like an operations manual. You need at least one on-site parking space per rented bedroom, and one on-street space may count toward the total. The access road has to work as the equivalent of a Category 3 road, or you seek an exception through a special permit. Daytime gatherings need an operational narrative, can't exceed twice the rental's maximum occupancy and are allowed only from 8 a.m. to 10 p.m.; the county notes that gatherings are the number one complaint about short-term rentals, that a substantiated complaint can lead to suspension if it isn't remedied, and that multiple substantiated complaints lead to revocation. Before applying, you give a Good Neighbor Guide to every neighbor with a dwelling within 300 feet, and you post it inside the rental with an evacuation route to the nearest highway. Parcels zoned AE, AG, TPZ or FR must apply as farm stays, with the owner or a farm tenant living on the property and an educational tie to the farm's work. Open code enforcement cases have to be resolved first. The ordinance replaced the county's old bed-and-breakfast provisions and its Vacation Rental combining zone, and entitlements approved under the old code remain valid.
Arcata regulates short-stay and vacation rentals, stays of up to 29 consecutive nights, under a permit program that began in March 2021. Ordinance 1559, adopted February 1, 2023, caps non-exempt permits at 100, and the city's FAQ, revised in September 2026, says the cap has been reached and a waitlist is open; when your turn comes, you have 72 hours to complete the application and pay. Three exemptions sit outside the cap: occasional use, no more than 29 nights in a fiscal year; owner-occupied, with the owner's primary residence on the same parcel; and historic landmark, inside a qualifying combining zone. Each unit needs its own permit, permits renew every year, non-exempt permits must show 30 rented nights in the prior fiscal year, and a permit doesn't transfer to a new owner or another address. Fees are $164 to apply, $110 to renew and $23 for the waitlist, and you also need a city business license and quarterly tax returns. Eureka splits the city in two. Inland, a vacation rental can be a whole house or part of one, rented for 30 consecutive days or less, in the residential R zones, and the inland mixed-use zones treat it as commercial lodging; in the coastal zone, which the city's rule of thumb places west of Broadway, north of 3rd Street and east of Myrtle Avenue, a vacation dwelling unit is a whole dwelling, principally permitted in the RS, RM, OR, CN and CS zones, while the CW waterfront zone also requires a conditional use permit and a coastal development permit, which the city says take about two to four months and cost around $3,300. Either way you need the city's vacation rental or vacation dwelling unit permit, a home occupation permit if you live in the city and run the unit yourself rather than through a property management company, a business license renewed each year, and a building inspection that checks for smoke and carbon monoxide detectors, fire extinguishers and a strapped, vented water heater. If you live off site, a postcard with your emergency contact goes to owners within 200 feet, and the contact goes to the police department. The permit lapses on February 1 unless the business license is renewed with taxes paid, and the city puts the usual total for permits, license and inspection at under $500 inland and under $550 in the coastal zone.
Trinidad and Ferndale work differently again. The City of Trinidad licenses short-term rentals inside its limits under its own ordinance, and the most detailed public account we found dates from 2017: that May, KRCR reported that the council had unanimously passed a cap the previous November, still awaiting certification by the California Coastal Commission, under which new licenses would be issued only when a space opened under the cap, rentals needed spacing between them, and a license wouldn't transfer with a sale but would go back to the city. Don't treat a 2017 report as today's rules: ask City Hall about the current cap, any waitlist, the license types and the lodging tax before you buy inside the city. Ferndale has its own vacation rental permit, added to its zoning ordinance in September 2017. A vacation rental there is an entire property with a single-family home, rented to one party at a time with no owner or manager on site, and the posted ordinance caps active permits at 24, allows one per owner, keeps rentals at least 600 feet apart in the residential zones unless the Planning Commission grants a waiver after a hearing, and requires annual renewal, a business license, a local contact who lives within 30 miles, visitors only between 7 a.m. and 10 p.m., and a special event permit for any event with more than 12 visitors. The city's 2026–27 fee schedule lists the permit at $500. Unlike an Arcata permit, a valid Ferndale permit stays with the house when it sells, as long as the buyer applies to renew it and gets a business license within two months. Vacation rentals are a principal permitted use in the single-family and two-family residential zones, while a bed-and-breakfast inn needs a use permit there, a lot of at least 20,000 square feet and an owner who lives in the house. Ferndale taxes the stay as a hotel, at 10 percent: register within ten days of starting, post the registration certificate, and remit by the 10th of each month. Treat this section as orientation rather than legal advice, and confirm current requirements with the county, the city, the California Coastal Commission where it applies, and any homeowners association before you list.
