Balconies, NYC Zoning, Help!

Ok. I read through the zoning laws as best I could. I definitely got caught up in some of the wording (I regularly read through Congressional bills, but this is just DENSE). This seems to be the pertinent section of the law:

By my reading, my neighbor’s building may be in violation of the last article (f) and possibly article (d). Assuming that I am correct, what is my next legal step? My first thought is to call 311, NYC’s information and public service line. Is getting in touch with my landlord’s neighbor a better way to handle it? I’ve never been in this situation before.
