The single mother, who is a minority per your comment, has every right to the housing which you describe - that's clearly established. There is absolutely no requirement that the landlord must further accommodate her by painting the words "Single mothers are my favorite," on the front of her house. The landlord is obligated, as you know since you work in EEO (did you mean EEOC?) law, to provide equal (and equal in every way - the amenities, rent, condition, etc.. must be equivalent to what the other tenants are also receiving. He can't charge her more if she receives less, and he can't restrict her living arrangements and options because of any class protection which she is duly entitled to) housing. There is NOTHING that says the landlord must make extra accommodations, cosmetically or aesthetically, to her, based on her class. That's what this is about. The baker offered to bake the cake, he offered to sell the cake - as he's required to do. No law dictates what the baker must write!
