The Illinois Safe Homes Act
 
The purpose of the Safe Homes Act is to enable victims of domestic violence, sexual violence, dating violence, or stalking and their families to flee existing dangerous rental housing or make their current rental housing safe.  This law allows tenants and members of their households who are survivors of violence to:

Sexual Harassment 
If your landlord is making unwanted sexual advances that are severe or pervasive enough to create an intimidating, hostile, or abusive housing environment, then he is guilty of creating an hostile environment and is in violation of the federal Fair Housing Act. Similarly, if your landlord asks you to trade sexual favors for a reduced rent or other benefits, or if your landlord evicts you because you refused to have sex with him/her, then he is guilty of sexual harassment.

Retaliation
If your landlord evicts you because you reported sexual harassment, or any other form of discrimination, then they are in violation of the law.
