I don't know what generation you are but I'm 56, grew up in a blue collar family in the rust belt and only a few kids were out of the house at 18. There were a few who went away to college but even they came home every break and after graduation until they got enough money to move out. Most kids were home until they were at least 20 and had saved enough to move in with a couple of friends.
But, to answer the OP, you need to set expectation with your DS. He needs to either be in school or at work, even if that job is part time. It doesn't matter if he's a legal adult, since he's living in the house, you can set home rules. My 18 yo has suffers from ADHD/depression and I still restrict internet access between 11PM and 6AM. He can, of course, use data if he uses his cell phone (which I still pay for and have restricted the amount of data he can use) but he's not playing video games all night. I try and make it easier for him to make good choices that keep him healthy mentally and physically. Good luck.
