Should Rent Factor in Utilities?

[Noah Barba]

Hey guys, pretty basic question here: should I include utilities in the rent? Not only should I do it, but does the rent someone sees listed on Zillow, realtor, etc. include the utilities? 

When estimating a property I've learned to sum up all the monthly expenses in order to find if "market rent" for the area would leave enough cash flow in the deal. Since that is how I estimate a property, wouldn't I include the utilities in the listed rent? Thanks to anyone who can help me straighten this out in my head!
