I had a similar issue at an apartment complex with my Oregon State Beavers flag. They told me when I moved in flags were allowed, just not all the time. Six months and a change of management later flags were no longer allowed. While not as bold as the reddit author I ended up flying old glory as often as possible. Also, the windows in the management office had a direct view of my balcony and whichever flag was flying from it.
