Rafael, I generally take a rather generic approach to finding out “anything.” In the case of legal and permit history, I’d first run an online search to see if there was any news coverage of such disputes from the relevant city — to give me some idea if there were specifics to be aware of. Then I’d simply phone the city’s administrative office and go into my “Who should I speak with to find out this ______?” routine. That question is highly recycleable as I get passed from person to person until I get a useful “hit.”
In the case of a city, their relevant department might be called something like “Construction and Permits” or any of a dozen other names, and it may or may not be hidden inside some other division. Instead of wasting much time trying to guess, let them tell you the where and who.
