Madison County, IL Parking Rules: Commercial & Oversized Vehicles (2026)

097(B), the zoning code's Trailers and Recreational Vehicles section, governs vehicle parking on residential lots in unincorporated Madison County. 007 describe as a large cargo vehicle designed to be hauled by a truck or tractor, meaning the kind of semi-trailer a commercial truck pulls. 097(B)(3) allows recreational equipment or trailers to sit on a driveway, street or adjacent right-of-way solely while actively loading or unloading for a period of time not to exceed 48 consecutive hours in any one-week period, and even then the equipment must sit on a paved or graveled all-weather surface, stay unoccupied, and never impede safe entry, exit or emergency access to the house.

Boats, campers and camping trailers are capped at four per residential lot in the rear or side yard, with one more allowed in the front driveway, at least 30 feet back, on lots of two acres or larger. 097, the zoning definitions section also limits an accessory private garage to storing not more than one commercial vehicle with a load capacity not exceeding one and one-half tons, meaning heavier trucks cannot be stored on residential property even inside an enclosed garage. Zoning enforcement runs through the county's Planning & Development office and the Zoning Administrator.
