It varies based on the homeowner or management company, keep in mind that all leases are different. In my experience, most apartment community leases charge a "utilities" fee on top of the base rent which usually includes trash/snow removal, exterior maintenance, exterior electricity, water/sewage. Gas, electricity, cable, internet are typically paid for by the lessee (you). If you are working with a homeowner or management company for an individually owned property, sometimes they can be more flexible and work with you, though not always.
If you haven't used the Trulia affordability calculator yet, I urge you to do so. It will help you determine the differences in the costs associated with renting and owning.
Please do not hesitate to let me know if you have any further questions!

I think the general rule of thumb is that the higher the rent, the more utilities you will pay. The idea being that the most desirable rental communities don't have to discount rents or include your utilities to maintain high occupancy rates, and the more desirable the more community, the higher the rent will be. The one exception to that is the category of senior rental communities. Properties like Yale Station apartments, which caters exclusively to the senior community, include utilities in their rent, yet they have reasonable rents are considered to be very desirable.
Best of luck to you!
