I don't want to sound rude, or daft here, but he is 14, yes? And he is your son.
Why would you make him buy his own deoderant and clothes? Surely that is the same as buying the rest of the household toiletries and such.
I am concerned that while there is nothing really outrageous on your regular list, being the person solely responsible for the yard etc is taking things a bit far. This is his home, not a workcamp, and I worry that you are overthinking this and turning what should be about family/community/belonging/contributing into work, iyswim.
