A new Illinois law requiring all public single-use restrooms to be gender-free went into effect on January 1. The Equitable Restroom Act mandates that single-occupancy facilities shall be labeled “All-Gender.”

The law defines “single-occupancy” as “a fully enclosed room, with a locking mechanism controlled by the user, containing a sink, toilet stall, and no more than one urinal.”

Gendered multi-user restrooms will still be available and many public places offer both types. Many gender-free single-use facilities are currently labeled as “family,” but others have retained gender restrictions for no apparent reason.

This new law applies to any existing or future public buildings or places of public accommodations like restaurants or shopping centers.

The Illinois Department of Public Health will inspect public facilities to ensure compliance with the law.
