An ordinance is no good if it is not enforced. In my area, I have neighbors on both sides and across the street.  My complaint is the neighbors across the street have someone come and pick them up at 1:00am, they blow thier horn to let them know they are there, and keep blowing it until the person comes out, its hard to confront these people as this house has different people moving in and out from day to day, not sure what is going on there, So not sure what one would encounter if they approached them at that time in the morning.  The neighbors next to me approx. the same distance away have the same problem, except they start blowing their horn at 6:30 am, I get up at 7am so this one does not bother me as much.  But as anyone knows the first 3 hours of sleep are best, but not when you are brought fully awake by blowing horns at 1am.
