Verizon is always in my neighborhood trying to get landlord permission they go door to door to door asking for landlord permission to be able to install fios. Lucky for me my landlord allows them but others have not and my neighbor is depressed I get super fast feeds and he is stuck with either DSL or Cable.
Whats funny Verizon is allowed to install DSL just not FIOS because of the ONT.
If the building is not too far away, you could share the network over ether WIFI or a LOONG weatherproof Ethernet cable.. (don't cheap out, use the good stuff)
