(55 ILCS 5/5-43025)
    Sec. 5-43025. Administrative hearing proceedings.
    (a) Any ordinance establishing a system of administrative adjudication, pursuant to this Division, shall afford parties due process of law, including notice and opportunity for hearing. Parties shall be served with process in a manner reasonably calculated to give them actual notice, including, as appropriate, personal service of process upon a party or its employees or agents; service by mail at a party's address; or notice that is posted upon the property where the violation is found when the party is the owner or manager of the property. In counties with a population under 3,000,000, if the notice requires the respondent to answer within a certain amount of time, the county or participating unit of local government must reply to the answer within the same amount of time afforded to the respondent.
    (b) Parties shall be given notice of an adjudicatory hearing that includes the type and nature of the code violation to be adjudicated, the date and location of the adjudicatory hearing, the legal authority and jurisdiction under which the hearing is to be held, and the penalties for failure to appear at the hearing.
    (c) Parties shall be provided with an opportunity for a hearing during which they may be represented by counsel, present witnesses, and cross-examine opposing witnesses. Parties may request the hearing officer to issue subpoenas to direct the attendance and testimony of relevant witnesses and the production of relevant documents. Hearings shall be scheduled with reasonable promptness, except that for hearings scheduled in all non-emergency situations, if requested by the defendant, the defendant shall have at least 15 days after service of process to prepare for a hearing. For purposes of this subsection (c), "non-emergency situation" means any situation that does not reasonably constitute a threat to the public interest, safety, or welfare. If service is provided by mail, the 15-day period shall begin to run on the day that the notice is deposited in the mail.
