Tax Deduction for Landlords question

[Max T.]

Can I deduct water bills and/or electric bills (common hall/basement lights) as a business expense for a non owner occupied duplex?

Water is the only utility that the city does not allow to be split/submetered or put into the names of the tenants.

I can't think of a reason why not, but I don't know why I haven't been doing this all along.
