I responded because I didn't want my meter locked out until a full check was done as it was an apartment building. 

I was initially nervous to bring one in and pay for the extra electricity to run loads because our meter was running about $5 in energy a day!

Specifically, the utility commission "... allow a lessor of a residential building or complex that has individually metered units for electric service in the lessor's name to charge for the actual costs of providing electric service to each tenant when the lessor has a separate lease for each bedroom..."

They are self locking knobs.I also had a box make for packages to be placed in the rear of the building.I gave the electric company a “dummy” key that will only work on a common door- no others, to get in to meters in one building.

I do not have a very commanding presence, and while I talk sternly to tenants if required, I feel like I have no leverage in this situation because the tenants will keep ignoring me unless I "do" something, not just talk.Making matters worse is the fact that they are dirt poor, and my sympathy meter kicks in.  

But I had some issues with the water bill due to a broken water meter.

I am also in the process of getting a house meter installed since the common areas are hooked up to their panel.

We could buy a city sticker that allowed us to park only in certain parking spots that were interspersed with metered spots.  

@Katherine Rossell the only really proper way to sub-meter heat is to install separate smaller heating units unique to each unit.  

You bet @David Zheng, even crazier when they rip the meter box off of the building.
