Unincorporated Clark County does not require a building permit for fences seven feet or less in height. Fences over seven feet, and retaining walls over four feet (or any wall carrying a surcharge), do require a permit.
Per Clark County Community Development, fences seven feet or less in height do not require a permit (the footing must be inward-facing). Fences taller than seven feet trigger a permit and must meet setback requirements. Retaining walls over four feet in height, or retaining walls at any height carrying a surcharge, require a permit, and all permitted retaining walls must be engineered by a Washington State registered engineer. CCC 40.320.010(F)(1) notes that building codes specify when retaining walls and fences require building and grading permits, and changes to stormwater runoff from walls fall under Chapter 40.386.
Building without a required permit is a code-enforcement violation; the county may issue a stop-work order, require after-the-fact permits, engineering, or removal.
