You just can't deny them simply because they belong to a few protected classes.But, that doesn't mean that just because they are in a protected class, that they also can be a smoker or show up late, blah blah.You also have rights as a landlord.

Just like theoretically, no disrespect, you should stick to cooking and cleaning (not my opinion).

I have a tenant in one of my houses that is a smoker.

I really don't want smokers.

The property is smoker friendly but the extent of his smoking seems over and above.

No animals or smokers.

I recently had a resident apply to live in a home in Cook County.

Hi @Kirsten Cooke, was there a specific "bounce" reason?  

When tenants stop paying for utilities other problems arise, such as burning candles for light, using propane devices for heating, and BBQs for cooking, running extension cords from other residences and overloading them, and in the winter, freezing pipes.... to name a few.

Out west, it's usually natural gas.A lot of tenants prefer to cook with gas over electric, so that could be a bonus, if you install gas.Gas dryers and hot water heaters are also often more efficient.
