Hi @Rebecca ,
Perhaps not the spirit of your topic but we have designated 'quiet hours' as part of our community regulations/noise ordinances. The local noise ordinances are enforceable by local enforcement agency (police, fire, permit authority).
Our community quiet hours are 9pm - 7am. This info is part of our permit and we are obligated to let guests know about this (and all the other permit restrictions).
In our case, while we take hosting and hospitality seriously, our first obligation is to be good neighbor and community member. And adhering to the quiet hours to the best of our ability is important to us. Imagine if you had to put up with a different group of noisy neighbors every weekend! It would drive you nuts.
In reality, we haven't had to enforce the noise issue and our marketing and messaging seem to do the trick in attracting guests who aren't likely to be an issue.
