duplex water meters

[Raul Velazquez Jr]

This question goes out to all multifamily owners/landlords in Columbus, Ohio. Is it a normal thing for duplexes to have a single water meter coming in from the city? Where the water is in the owner's name and the tenants pay the owner(sub-metering). I was under the impression that some duplexes were plumbed separately. Can you please help a newbie out!? Thanks in advance.
