Do I need a permit for retaining wall construction in Unincorporated Clark County?
Most likely yes. Retaining wall construction usually requires a permit in Nevada. Confirm the specifics with Unincorporated Clark County.
Nevada has not adopted a statewide height exemption for retaining walls; whether a short wall is exempt depends on the building code your city or county adopted under NRS 278.580. Nevada requires every local building code to include the seismic provisions of the International Building Code and standards for investigating seismic hazards (NRS 278.580(6)). Before digging with power equipment, or by hand more than 12 inches deep, where buried utilities may be present, notify the one-call association at least 2 working days and no more than 28 calendar days ahead (NRS 455.110 and 455.092). Grading, drainage, and walls near property lines may also need local grading or zoning approval.
