Can A Casita Or Guest House Have Separate Meters For Electric?

A reader and downtown neighbor asked the question, and I don’t know the answer. Though there’s certainly plenty of legal as well as illegal guest houses and casitas, I’ve never run across one that did have separate meters for the power.

Could a sub-meter be installed which just the owner read? Will Nevada Power allow a separate account for the 2^nd meter?

Have any of you ever researched it? Know anyone who accomplished it?
