You would be better off doing research on the City Codes. There are usually some universal standard ones that most if not all Cities will use, but they may also make changes or additions to better suit their environment.
Best idea is to go to the local City Office and speak to someone there, probably in Zoning of Building Inspection. Ask to see the relevant Codes. They are Public Records so they cannot refuse you.
It is totally irrelevant what anyone online, me included, tells you as *only* the Code defined by that specific and individual City means anything to this case.
Were you or a family member that "a citizen?"
