Illinois Statutes Chapter 770. Liens § 50/1. Labor, services, materials on or storage of chattels; towed vehicles; consent

§ 1. Every person expending labor, services, skill or material upon or furnishing storage for any chattel at the request of or with the consent of its owner, authorized agent of the owner, or lawful possessor thereof, in the amount of $2,000 or less, shall have a lien upon such chattel beginning upon the date of commencement of such expenditure of labor, services, skill, or materials or furnishing of storage, for the contract price for all such expenditure of labor, services, skill, or material, until the possession of such chattel is voluntarily relinquished to such owner or authorized agent, or to one entitled to the possession thereof.

For the purposes of this Act, a person, other than a driver or a person otherwise in control of a fire, police, emergency or public utility vehicle on official business, consents to removal by towing of his or her vehicle when he or she without authorization parks such vehicle upon private property while having notice that unauthorized vehicles will be towed from such property by the owner of such property, or agent thereof, at the vehicle owner's expense, where such notice is provided pursuant to State law, local ordinances or regulation by any state or local agency. Such notice must include a sign of at least 24 inches in height by 36 inches in width posted in a conspicuous place in the affected area at least 4 feet from the ground but not more than 8 feet from the ground. Such sign shall be either illuminated or painted with reflective paint, or both and shall state the amount of towing charges to which the person may be subjected. However, the requirement of the sign provided for in this section shall not apply to residential property which, paying due regard to the circumstances and the surrounding area, is clearly reserved or intended exclusively for the use or occupation of residents or their vehicles.

The lien established herein shall also apply to labor, services, skills or material upon or furnishing storage for towed vehicles performed by any relocator or any other towing service pursuant to the order of a law enforcement official or agency in accordance with Sections 4-201 through 4-214 of The Illinois Vehicle Code.  1 The lien created herein shall be valid even though the towing and storage is performed without the vehicle owner's consent.
