Amends the Illinois Civil Rights Act of 2003. Prohibits an otherwise qualified individual with a disability, as defined by the Environmental Barriers Act, from being excluded from participation in, be denied the benefits of, or be subjected to discrimination solely by reason of the individual's disability under any of the following: (i) any program or activity operating inside Illinois and receiving federal financial assistance; (ii) any program or activity receiving federal financial assistance that passes through or is administered by State, county, or local government; (iii) any activity regulated by the State that receives federal financial assistance; or (iv) any program or activity receiving State, county, or local government financial assistance. Provides that a State agency that has an existing mechanism for enforcing federal Section 504 rights under the federal Rehabilitation Act may also enforce provisions of the Act. Authorizes the Attorney General to commence a civil action to enforce the provisions of this Act in any appropriate circuit court if the Attorney General has reasonable cause to believe that any person or group of persons is engaged in a pattern of discrimination prohibited by this Act. Provides that disability discrimination under the Act includes violations of the substantive rights provided in the federal regulations adopted under the federal Rehabilitation Act. Provides that these rights constitute a minimum set of rights that may not be reduced. Requires the Secretary of State to maintain a copy of the regulations in a manner that is easily available to the public such as on a website in a searchable format. Makes the Act severable.
