I often follow this up with "We don't want *any* household members running up and down the halls jumping, playing with the sprinklers, or using crayons on the walls."

Be really careful using the word minors, use words like members of your household and guests. Minors are children and using the word will open the door to a lawsuit.
Some PM companies take a family pic when people move in and give the pic to the family in a nice frame as a move in gift and also keep a copy in the file so they know which kids belong to who so you can give a notice to the household foe household member behaviors.
Also, getting to know kids on your property is the best thing to do. Once they get to know you, they will be your ears and eyes and tell you everything. A little candy in the office goes a long way.
Good luck.

I had issues at a property with the kids. I focused on making them my allies. Not all came to the dark side but enough of them did that peer pressure kept things from being too bad. I’d make time to meet them as they got off the bus and hand out treats- once a week. I’d get to know their names and talk to them and then remember them. It wasn’t an overnight change but it did come around.

Be very careful with this. You can hold them accountable if you definitely have proof it was them. Document everything well. Choose your words. Best to not use words like children or kids. Use occupants. Do not get personal in the rule violation letter. In other words, it’s best to not say things like “unsupervised “. Stick to the facts.

I would make sure we have activities for the kids like a safe playground. Basketball court, a gazebo with lighting for reading and bbq, camera and make parents accountable for their children.

I won’t say minors or adults. I use “your household members”
