I started charging room and board from my son when he turned 19 (age of majority where I live). It barely covered his food and his share of the bills, and then he could save the rest to put towards a place when he was ready. Throughout his teen years, I contributed to the male version of a "hope chest" so he had stuff when he moved out. Bathmat, shower curtain, towels, etc for Christmas one year; kitchen cutlery, cooking utensils, hot mats, oven gloves, etc for his birthday one year; sheets, pillows, blankets for another birthday.... you get the idea. He had almost everything except large furniture by the time he moved out, and was able to buy decent second hand furniture when it was time. So, joint effort.
