Full Breakdown
Will County Code § 155-11.65(A) bans parking or storing commercial vehicles or trucks with an Illinois plate above Class D, including truck tractors and tow trucks, on A-2 and residential-zoned lots, with narrow exceptions for active delivery, landscaping, utility, or construction work. Lighter commercial vehicles (Class D or below) and commercial trailers are capped at 1-2 per lot depending on the zoning district, must sit on a constructed driveway, show no visible load, and stay under 90 inches tall. This only governs unincorporated county land; Joliet, Bolingbrook, Romeoville, Plainfield and Lockport enforce their own municipal parking codes.
Violations & Fines
The Zoning Administrator enforces zoning violations under § 155-17.20, with each week a violation goes uncorrected counting as a separate offense; remedies include permit denial or revocation, stop-work orders, injunctive relief, and administrative adjudication under Chapter 43.
