I have to agree with TheNorman. After looking at the satellite view map now it appears there is nothing wrong with this for now. It may be worthwhile to see who the 'chief' equivalent is at that office and try to schedule a call with him or her and discuss it. I'm sure it could be worked out. And a discussion could be had between him/her and the 'security' people.
And if they are mean about it and ask who you are, just say TexasWriter or Mustard Devil or something.
