60 ILCS 1/110-17
A veteran with a disability or the veteran's caregiver shall not be charged any building permit fee for improvements to the residence of the veteran with a disability if the improvements are required to accommodate a disability of the veteran. Nothing in this Section changes the obligation of any person to submit to the township applications, forms, or other paperwork to obtain a building permit. A veteran or caregiver must provide proof of veteran status and attest to the fact that the improvements to the residence are required to accommodate the veteran's disability. Proof of veteran status is to be construed liberally, and veteran status shall include service in the Armed Forces of the United States, National Guard, or the reserves of the Armed Forces of the United States. What constitutes proof of veteran status shall be determined by the township. The Illinois Department of Veterans' Affairs may not adjudicate any dispute arising under this paragraph.
