Lexington County, SC Parking Rules: Commercial & Oversized Vehicles (2026)

Section 21.21.m regulates the repetitive parking of commercial-type vehicles as an accessory activity to a residential use, and sorts vehicles into four tiers. Standard pickups, including two-door and four-door extended-cab models and six-wheel dual-rear-wheel trucks, are allowed with no restriction. A second tier, small commercial vans, tour vans, privately owned ambulances, RVs, school buses, and garden or farm tractors, must be properly licensed and parked completely off the road right-of-way. A third tier, including large step vans, tractor-trailer cabs alone, and tow trucks, must sit beyond any setback line the ordinance imposes; on-call employees' commercial vehicles or equipment get the same treatment as long as storage doesn't exceed 48 hours in a given week and doesn't violate any HOA covenant. A fourth tier, car carriers, glass carriers, tour minibuses, full tractor-trailer combinations, dump trucks, moving vans, flatbeds, and backhoes, is allowed only if completely screened from the road and all surrounding property.

Some equipment is barred outright regardless of screening: full-size tour buses, vehicles hauling hazardous materials, tanker trucks carrying hazardous or flammable liquids or gases, motor graders, front-end loaders and other earthmoving equipment, garbage trucks, and bucket trucks. The ordinance is explicit that a variance from the Board of Zoning Appeals is not available as relief for the prohibited category, and there is no grandfathering for existing violations of any tier of § 21.21.m, unlike some other nonconformities the ordinance otherwise tolerates.
