Illinois: Laws & Regulations

Illinois’s Laws & Regulations for Assistance Animals are as follows:

Acceptance

Emotional Support Animals (ESA):Accepted with Conditions

Psychiatric Support Animals (PSA):Accepted Nationwide

Service Animals:Accepted Nationwide

Tip:Always carry your Physical ID Card and visible Recognition Gear. In Illinois, bringing a Prescription Letter, Registration Certificate, and Behavior Certificate greatly reduces delays in urban areas such as Chicago, Springfield, and suburban municipalities.

Housing

Illinois housing providers follow the federal Fair Housing Act (FHA), requiring landlords to reasonably accommodate assistance animals—including ESAs, PSAs, and Service Animals—when supported by appropriate documentation. Illinois also enforces the Illinois Human Rights Act, offering additional protections for tenants with disabilities.

Air Travel

All flights to or from Illinois follow the Air Carrier Access Act (ACAA). Only trained service dogs qualify as Service Animals. ESAs must travel under airline pet rules. DOT Service Animal forms may be required at major airports including O’Hare (ORD), Midway (MDW), and regional airports.

Tip:Our registry is approved by all airlines — your Physical ID Card, Registration Certificate, and Recognition Gear help airline staff confirm documentation quickly at Illinois airports.

Public Access

Illinois public access follows the Americans with Disabilities Act (ADA) as well as the Illinois Service Animal Access Act. Only trained Service Dogs (including psychiatric service dogs) must be allowed in restaurants, hotels, retail stores, public transit, hospitals, schools, and government buildings. ESAs are not considered Service Animals and have no public-access rights.
