I don't know about your area... but in most parts of Ohio, anyone can be as loud as they want until 10:00 PM. At that time, disturbance of the peace kicks in, and complaints may be filed. How do I know? I'm the sound tech for a chuch band that occasionally practices in members' garages... just for a change of scenery. We've had a couple of complaints called in, but the police know who we are, what we're doing, and they don't officially file any complaints until 10. And we stop at exactly 9:59 PM. See, we're even giving them a little more time!
