Exactly, if she wants to be an adult and do whatever she wants to do she needs to pay rent.

Also, the level of harshness in your requirements needs to be very sparing and proportional to the risk. If your idea of “bad news” means some of her friends that might be a bit more relaxed about certain religious or moral values than you like, you really can’t do much about it. If they’re gang members and drug traffickers who might get her arrested or a stray bullet in a drive-by, then you should be willing to risk what you can to keep her from going, You only have so much moral and relationship capital with your daughter as an adult (or even as a teen). Don’t spend it all fighting over trivial things, and only put your foot down when you really have to, because it’s a major issue of health and safety. If you fight with her because of every small thing, she won’t listen or care when it’s real, true, dial-to-a-nine bad news or bad things going down.

Yep. As a former teenager, explain that you're concerned about some of the people you've heard are going to be at this party, and that while you know you raised her properly and trust her to make good decisions, you also know shit happens. Also remind her that it doesn't matter what time it is or where she is, if she calls you asking you to come get her, you will. That's what my parents did with me, and guess what? I never got myself into trouble because I had nothing to prove.

This. This is the best thing to do and one person above this spelled out this specifically. If you want to have her respect your wisdom, you can’t lay down the law of the land. You need to acknowledge that she is an adult, and talk concerns out like adults do. This can earn massive respect for what you say from your daughter, while also giving her an out if she finds out her decision is leading down a bad path. That last part means instead of going full-blown retar…. Err… doing something insanely stupid because they already started down that path and don’t see an exit, providing an out means the difference of driving bleary eyed at 2 am to pick her up, and sitting in court trying to explain she’s a good person but misguided. Adults (normally) use ration and reasoning, and it gives mad props for respect when you treat them like one and recognize it. Buckle up, it’s gonna be a bumpy ride here but eventually when you establish that repertoire, when you truly need to pull rank over something super dangerous, it’s a lot more likely they’ll listen to save them from a folly. Picking your battles on authority means something big when you do need to flex that. I wish my mother had understood that. It held back personal growth because of her dumb rank pulling left and right. It caused me to do the opposite in spite.
