All adjacent homes qualify for gig fiber, not me. Who do I call?

I live in a close-in NE Portland neighborhood where CenturyLink offers 1-Gig FTTH service. I've confirmed that fiber is available here with more than a couple neighbors, a CL retail sales rep, CL technicians out making their rounds, a CL construction crew that was stringing fiber overhead, as well as by checking for service availability using CL's online sales portal. Unfortunately, while all of my surrounding neighbors appear to qualify for fiber service, I live in a small fifteen unit apartment building that only qualifies for 20 Mbps DSL. I was hoping that someone might have a suggestion as to who I should talk to to see if I can't get past this little bump in the road. Thanks.
