Arcata's Land Use Code Section 9.42.030 governs accessory structures. One portable storage shed per residential lot is exempt from a building permit when consistent with the California Building Code's 120 sq ft / one-story threshold, but it must still meet the setback, height, and parking standards of the underlying zoning district. Section 9.20.030 lists accessory structures as an allowed use.
Humboldt County permits accessory dwelling units (ADUs) and junior ADUs in any zone allowing single-family or multifamily residential use, with ministerial 60-day approval, 4-foot side/rear setbacks, detached size cap of 1,200 sq ft, attached cap of 50% of the primary residence, and a prohibition on short-term rentals of 30 days or less.

Humboldt County does not impose a breed-specific dog ban, and California state law affirmatively prohibits any local ordinance that is 'specific as to breed' for the purpose of declaring a dog dangerous or banning ownership – Food and Agricultural Code section 31683 only allows breed-specific spay/neuter or breeding requirements in unincorporated areas, not breed-based ownership bans.
Neither California state law nor Humboldt County's published Animal Control materials set a hard numeric cap on companion pets per household in unincorporated areas, but once the number of dogs reaches a 'kennel' threshold the operation becomes a regulated land use that must comply with the County's Inland and Coastal Zoning Regulations and obtain the appropriate use permit through the Planning & Building Department.
Humboldt County Animal Control (operated by the Humboldt County Sheriff's Office) enforces dog-at-large and leash rules in unincorporated areas, and California state law requires every dog over four months of age to be licensed and currently vaccinated against rabies.
In unincorporated Humboldt County residential zones (RS, R-1, R-2), solid fences within the front-yard setback are capped at 3 feet, while open fences (at least 70% open to light and air) may reach 7 feet. Outside the front-yard setback, fences up to 6 feet are generally allowed without a zoning or building permit.
Fences six feet or under do not need a Humboldt County building or zoning permit. A building permit from the Building Inspection Division is required for any fence taller than six feet. Any fence or gate built in or adjacent to a County road right-of-way also needs an encroachment permit from Public Works.
In residential front-yard setbacks, only fences that are at least 70% open to the passage of light and air qualify for the taller 7-foot allowance. Chain link or other woven wire smaller than 6-gauge is prohibited in the front-yard setback, and fences in the road visibility triangle must not obstruct vision.
California Civil Code Section 841 (the Good Neighbor Fence Act) governs shared boundary fences in unincorporated Humboldt County.

California sets no fixed dollar or percentage cap on rent late fees, but a late fee in a residential lease is treated as liquidated damages. Under Civil Code § 1671, such a fee is valid only if it reasonably estimates the landlord's actual loss from late payment; arbitrary penalty fees are unenforceable.
To end a California month-to-month tenancy, a tenant gives 30 days' written notice. A landlord gives 30 days if the tenant has lived there under a year, or 60 days if a year or more, under Civ. Code § 1946.1. AB 1482 requires just cause after 12 months; military and DV tenants may exit early.
