In my experience it's just a case of knowing who to call and what to ask for. We are served by Spectrum. They will drop fiber into any building in their HFC service areas. We had it into an apartment building for several years then moved to another building with only coax, but they quoted me $2000 install for fiber. Problem for me is that the fiber service is symmetric and so to get the kind of download needed for Netflix you have to pay for 200M+ upload. That's quite expensive for me so I passed. They don't offer 95% billing.
