The best thing to do is to work with a real estate broker or a leasing agent. Typically, in older building that have steam heat the landlord pays for it. However, you are than responsible for your own electric, cable, internet, etc. Also pet policy.
Most condos that are rentals that are walk up require that you pay all your utilities accept, water, sewage, and waste removal.
The newer buildings and some rehabbed buildings require that the tenant pay a flat fee for heating, water, and sewage depending on the size of the apartment.
There is not one answer to your questions each situation is different.
I hope this is helpful.
