Lot of good research going on out there regarding issues such as these where some city hall nazi's think they can run roughshod over people by using some of their codes and to justify their actions. Let me ask you......if a CORPORATION (aka artificial entity) such as IBM sent you a letter saying because you live within a mile of their office then you're bound to follow their internal codes of conduct for whatever.... you'd tell them to shove it........likewise what gives another artificial entity such as CORPORATE muni- gov any right to tell you that according to one of their codes you have to keep your grass at a certain height?
Key question is where is their authority to do so?.......did you grant them control over your life and property?
Just because they "presume" to have that right does it make it so? Codes, regulations and ordinances ARE NOT POSTIVE LAW thus they have no force of law. Most problems with city officials or their "third party" reps (aka shyster lawyers) can be shut down immediately with the right response.
