nyc: I rent space in a real old building in NYC. I need to contact the building owner, but the management company never lets me. The building is in dire shape and I have a feeling the management company doesn't want the owner to find out. Any Ideas on how to find the owner?? Tax Records?|||the county accessor, treasurer, clerk or any title firm.|||Go on line to the county assessors office and look up that address. If you find that an LLC or other partnership owns the property you would then proceed to the secretary of state's website and find out ( if you can) the members of the partnership. Good Luck!!
