Summary

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.

These county ordinances apply to unincorporated areas of Humboldt County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Most fences under 6 feet in height do not require a permit from the Planning & Building Department. Fences must be constructed outside of the public right of way for the County road. If you are building a fence or a gate near a County maintained road please contact the Encroachment Permit Office of the Public Works Land Use Division at 707.445.7205. Public Works staff can meet you on-site at no cost to you.

Full Breakdown

Per Humboldt County's Planning & Building Department, fences up to six feet in height are exempt from both zoning setback and building permit requirements. A fence over six feet is subject to the underlying zone's setback from property lines and requires a building permit from the Building Inspection Division. Humboldt County Code Section 331-11 incorporates the California Building Code by reference; the State CBC exempts fences up to 7 feet, but the County's six-foot threshold is more restrictive and therefore controls in unincorporated Humboldt County. (A pending Commercial Residential Zoning Update would change the definition of 'structure' to exempt fences up to seven feet, matching State code, but the current rule is six feet.) Separately, any fence or gate built in or adjacent to a County-maintained road right-of-way requires an encroachment permit from the Public Works Land Use Division (707-445-7205). Property owners building near roads should call Public Works before construction; staff can meet on-site at no cost.

Violations & Fines

Building a fence over six feet without a building permit is a violation of Section 331-11 and the California Building Code; the Building Division can issue a stop-work order, require a permit after the fact (typically at higher fees), or require removal if the fence cannot be brought into compliance. Building in the road right-of-way without an encroachment permit is an unlawful encroachment that Public Works may abate.

Frequently Asked Questions

Do I need a permit for a standard 6-foot backyard fence?
No. Humboldt County exempts fences six feet or under from both zoning setback and building permit requirements. You should still check setback rules in residential front yards (Section 314-73) and the visibility triangle near roads.
What about a 7-foot fence -- isn't that exempt under state code?
Not yet in unincorporated Humboldt County. The California Building Code exempts fences up to 7 feet, but Humboldt County Code Section 331-11 keeps the six-foot threshold and the most restrictive standard applies. A pending zoning update would raise the exemption to 7 feet, but until adopted, anything over 6 feet needs a building permit.
Do I need a separate permit if my fence is near a County road?
Yes. Public Works requires an encroachment permit for any work in or adjacent to the County road right-of-way. Call the Land Use Division at 707-445-7205 before you build; staff will meet you on-site at no cost.
