I did look up the ordinance and it does appear he has a right to complain if it disturbs his peace --even if difficult child stood in our front lawn. What I should do is get him lessons and look into what Farmwife said about a permit for a street performer. What he likes about it is that people have been giving him tips. That wasn't his idea at first, but after the first person did it he thought - hmmm I could make some money doing this! That is what draws him to it. He has a very entrepreneurial spirit. He loves doing things to make money. He rakes peoples leaves, shovels snow, sells lemonade - even at our garage sales, he sells bottled water, pop, donuts, chips. He absolutely LOVES it. If I could get the kid a job (making money), he would love it! Oh - I am surprised the neighbor never turned him in for selling lemonade since apparently you now need a permit to do that!
Here is the way the law is written:
Any loud and raucous sound made by use of a musical instrument, whistle, sound amplifier, or other device capable of producing or reproducing sound which emanates frequently, repetitively or continuously from any building, structure or property, such as sound originating from a band session, tavern operation, or social gathering, and which unreasonably disturb, or interfere with the peace, comfort and repose of possessors of real property in the area affected by such noise.
