Mailbox for Basement?

[Jon Baker]

I am considering buying a SFH and converting the basement into a new "unit". I live in a major city so I don't want to mess with zoning. I would live in the basement and would have Long Term renters in the top. The basement has a separate entrance and I would add a small kitchen as well. There is a bedroom and bathroom and the entire basement is furnished. Has anyone done this and simply put a "B" mailbox out front so I wouldn't have to share my mail with the LT renter? I'm wondering if this is possible.

Thanks!
