The graffiti is now gone, but police said they are investigating two incidents of criminal damage and criminal defacement for derogatory graffiti.
The man who lives in a home on the 2400-block of West Winnemac Avenue said he and his partner placed a sign in their yard with positive messages that include, "Love is Love," and "Black Lives Matter."
The man said Sunday morning someone then spray-painted over that sign and spray-painted the words, "anti white" on their sidewalk.
A source told ABC7 there was other hate graffiti at another home in the 5000-block of North California Avenue.
While police are looking into the two cases, they are not calling them hate crimes.
