Summary
In unincorporated Clark County, a fence or wall (or a combined berm and fence/wall) may not exceed six feet above finished grade at its base, unless the review authority approves added height. Fences must not obstruct intersection sight distance.
A fence or wall (or a combination of a berm and fence or wall) may not exceed a height of six (6) feet above the finished grade at the base of the fence or wall (or at the base of a berm, if combined with one) unless the review authority finds additional height is necessary to mitigate potential adverse effects.
Full Breakdown
Clark County Code 40.320.010(C)(2)(a) caps fences or walls at six feet above finished grade at the base of the fence, wall, or berm. Additional height is allowed only where the review authority finds it necessary to mitigate adverse effects. Under 40.320.010(F), fences seven feet or less in height may sit within easements and generally within setbacks, while fences taller than seven feet must meet the underlying zone's setback requirements. Fences must never obstruct sight distance at intersections (Section 40.350.030). Cities within the county (Vancouver, Camas, Battle Ground, etc.) set their own fence rules; this covers unincorporated land only.
Violations & Fines
Fences exceeding limits or obstructing sight distance are code violations enforced by Community Development; owners may be ordered to lower or remove the fence and obtain required permits.
