So much for the assumption that 517 meant 5th floor.

Your friend should've went inside to find the real answer.

I just talked to the receptionist at TADF, the number listed on the website. She stated she was in suite 517 of a two story building at the address, 123 west Nye Lane,Carson City. The builing exist, the address exist, and the receptionisp answered the phone with "Tacital Air Defense, how may I help you? So lets put the "5 TH floor to rest!
