Several years ago there was an issue raised by the condo developer next door to 1406 Vermont. He was challenging our commercial use. There were hearings about the matter. (I believe we used an attorney but don't remember who) We proved that this bldg had been used as commercial for about 40 years and in any event was grandfathered in. The ruling was in our favor and we continued to use it as commercial. Is there a way to find that information please?
