Illinois Statutes Chapter 815. Business Transactions § 670/15. Adoption of building code

§ 15. Adoption of building code. A contract to build a home (1) in any municipality in this State that does not have a residential building code in effect or (2) in any portion of a county that is not located within a municipality and does not have a residential building code in effect must adopt as part of the construction contract the applicability of a residential building code that is agreed to by the home builder and the home purchaser as provided in this Section. The home builder and the home purchaser may agree to adopt any municipal residential building code or county residential building code that is in effect on the first day of construction in any county or municipality that is within 100 miles of the location of the new home. If the home builder and the home purchaser fail to agree to a residential building code or if no residential building code is stated in the contract, the plumbing code promulgated by the Illinois Department of Public Health under Section 35 of the Illinois Plumbing License Law, the National Electric Code as adopted by the American National Standards Institute, and the International Residential Code shall, by law, be adopted as part of the construction contract.
