This problem has been solved other places. For example, in Hong Kong, all operators have a statutory right of access to common areas of buildings to provision services to customers in the building.

Incorporated Owners/Building Management: "(a) should not impose any fees, deposit, access charge, administrative charge, escort charge or rental charge on the Operators for the access of the building, the use of the common parts of the building or the use of the in-building telecommunications system of the building for the provision of services to residents or occupiers of the building (b) should not enter into any commercial contract which will unreasonably restrict the right of a resident or occupier or deprives a resident or occupier of the right, to have access to the public telecommunications services of his choice. Any such agreement is void to the extent that it imposes such restriction;"

Would be nice to see similar legislation adopted in the USA.
