Summary
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.
Chain link fencing with 2" posts and 2" mesh (without privacy slats) can be an alternative if a tall fence is necessary within visibility triangle areas. Within the visibility triangle area vegetation must also trimmed and maintained so as not to obstruct visibility. Fences require setbacks at intersections and driveways. On road curves, fences may need greater setback distance.
Full Breakdown
Under Humboldt County Code Section 314-73 (inland) and Section 313-74 (Coastal Zone), an 'open fence' in residential zones must be at least seventy percent (70%) open to the passage of light and air to use the 7-foot height allowance within the front-yard setback. Chain link or other woven wire fencing smaller than six (6) gauge is expressly prohibited inside the front-yard setback. Within the visibility triangle at intersections and driveways (Section 341-2), 'visibility obstruction' includes hedges, bushes, natural growth, buildings, structures, fences and signs over three feet in height -- but fences of a type which do not obstruct vision are exempted. Public Works guidance specifically suggests that chain link with 2-inch posts and 2-inch mesh (no privacy slats) is an acceptable tall-fence option within the visibility triangle.
Violations & Fines
Installing solid fencing, chain link with privacy slats, or sub-6-gauge wire in a front-yard setback violates Section 314-73/313-74. Solid or view-blocking material installed in the road visibility triangle violates Section 341-2 and can be ordered removed by Public Works under the enforcement provisions of Chapter 341. Continued violations may result in administrative fines and abatement at the owner's expense.
