Illinois Statutes Chapter 735. Civil Procedure § 5/13-214. Construction; design management and supervision

(a) Actions based upon tort, contract or otherwise against any person for an act or omission of such person in the design, planning, supervision, observation or management of construction, or construction of an improvement to real property shall be commenced within 4 years from the time the person bringing an action, or his or her privity, knew or should reasonably have known of such act or omission. Notwithstanding any other provision of law, contract actions against a surety on a payment or performance bond shall be commenced, if at all, within the same time limitation applicable to the bond principal.

(b) No action based upon tort, contract or otherwise may be brought against any person for an act or omission of such person in the design, planning, supervision, observation or management of construction, or construction of an improvement to real property after 10 years have elapsed from the time of such act or omission. However, any person who discovers such act or omission prior to expiration of 10 years from the time of such act or omission shall in no event have less than 4 years to bring an action as provided in subsection (a) of this Section. Notwithstanding any other provision of law, contract actions against a surety on a payment or performance bond shall be commenced, if at all, within the same time limitation applicable to the bond principal.

(c) If a person otherwise entitled to bring an action could not have brought such action within the limitation periods herein solely because such person was under the age of 18 years, or a person with a developmental disability or a person with mental illness, then the limitation periods herein shall not begin to run until the person attains the age of 18 years, or the disability is removed.

(d) Subsection (b) shall not prohibit any action against a defendant who has expressly warranted or promised the improvement to real property for a longer period from being brought within that period.

(e) The limitations of this Section shall not apply to causes of action arising out of fraudulent misrepresentations or to fraudulent concealment of causes of action.

(f) Subsection (b) does not apply to an action that is based on personal injury, disability, disease, or death resulting from the discharge into the environment of asbestos.
