For condos rentals through realtors cleaning fees are often a norm - although they often have a baseline level of cleanliness where you don't have to pay a surcharge if it is to a certain standard such as all of the dishes either cleaned and put away or in the dishwasher cleaning while you check out and all trash cans emptied.

That sort of thing is a legitimate reason for a separate fee. I guess pedantically it is "non-baked in unconditional cleaning fees" essentially.
