Tenant or owner pays Utilities

[Carlos Cevallos]

I'm new to real estate and am in the education phase.  While reading @Brandon Turner 's Book on Rental Property Investing in chapter 10 under utilities it states that you should look for properties where utilities can be paid directly by the tenants. I thought all properties were like this, if they are not, how do you determine whether the tenants can pay directly or the owner has to pay?
