Full Breakdown
Waukesha County's zoning §3.12(7) bars parking or storing heavy or oversized commercial and industrial vehicular equipment on any lot except in the B-3, M-1, M-2, P-I, and Q-1 districts. The listed equipment includes trucks, construction vehicles, grading equipment, buses, semi-trailers, tractors, and similar vehicles, trailers, and related equipment. Active-farm agricultural equipment in an agricultural district is exempt, and a Conditional Use Permit under §3.08(7)(W) can authorize such vehicles in other districts (not the C-1 Conservancy or EC Environmental Corridor Overlays). A residence may keep at most one business van or pickup under §3.12(6)A. These rules apply in the unincorporated towns; cities and villages regulate oversized vehicles under their own codes.
Violations & Fines
Storing oversized commercial vehicles outside permitted districts is a zoning violation subject to citation, forfeitures, and removal orders by county Planning & Zoning.
