Separate Living with Separate Entrance - with a shared mailbox
We rent out the upper and lower levels of a single-family home. The units are separated by a stairwell and permanently locked door. The house functions like an upper-lower duplex. One issue that I have not been able to resolve is the "shared mailbox." I have asked the postal carrier about placing a mailbox next to the current mailbox to separate the tenants' mail, but he said that is not an option. Since it is a "single-family home" it can only have one mailbox. Has anyone else come across this issue? And do you have any suggestions on how to resolve.
Thanks!
