We did include utilities, only because the old 26 unit converted building was not separately metered and the owner didn't want to deal with doing it.We just did month to month agreements, so we could get rid of a problem quickly, if necessary.  

The heater was fine; the problem was the gas meter was locked because, despite providing them information on how to set up gas service two weeks before they moved in, they failed to do this.Gail

The building I managed was old and did not have separate meters, so electricity and gas was included in the rent. 

I don't include power in any of my units but do include water in the multis (in my city we can only get 1 water meter per property). 

For the MF we recently installed a meter to track and decrease use. 

So, losing a 4th bedroom and gaining a sweet master suite where among other things, I had all new 3/4" PEX water supply lines run all the way from the meter to the two all new upstairs bathrooms, so you had the "shower of power" while many of the neighbors had well kept older homes, but each morning had to shower under whatever dribbled out of those old, clogged up galvanized pipes!

Some areas have occupancy limits attached to square footage (or meters for you Edmonton folk). 

Some of the things to consider, how many gas/electric meters are there?

I added a water meter so that I can determine the individual tenants usage and informed the tenants that they will be paying for actual usage instead of a set fee.

Sounds like your poo-meter works pretty well.
