Section 8 voucher utilities included

[George Bell]

Hello, I have a few SFH rentals . I've never had a section 8 tenant but am looking for general information.

I know how to look up what section 8 would pay for rent based on bedrooms and fair market value for the area ,  but how does this work with utilities?

I heard that it can be paid by the program or by the tenant . 

Certain vouchers include utilities but is there a limit on how much they cover for utilities?

What if the  tenant can not pay the difference for what the voucher will cover and what the bill is  ? 

If there is a couple thousand dollar water bill and the tenant vacates then is this a landlord problem to pay ? Will the housing authority do anything in this instance?
