Ours were home educated, so based at home all through their teenage years.
We didn't impose any formal work, they can and did follow their own interests.
They can and did self regulate-and the two who still live at home still do.
They often go to bed after us, I remind them of the time I have to be up for work (often 6am) and they are very considerate.
I remind them sometimes, that I could do with more help around the house-and they will do whatever I ask-not always immediately, but it will be done if they say they will do it.
When they have to be up for something, they will take themselves to bed at a reasonable time.
Today for instance ds (22) was in court as a witness at 10am, so yesterday washed and pressed his clothes and got himself off to bed and then up in plenty of time to make himself presentable.
DD(16) had an audition at college for a music course so she got herself off to bed and then up early to organise herself.
We work on consensual living -finding a solution that makes everyone happy.
We wouldn't impose any rules that are hard and fast-in fact no rules at all, just promote mutual respect.
Up to them if they stay awake through the night and sleep next day-as long as they don't disturb me, I'm happy.
Worked so far for us-even had sons friends come back to the house after going to the pub to celebrate his birthday earlier in the month.
I went off to bed having left a notice up, reminding them to 'please leave through the back door as I have to leave for work at 6am'-and they did just that and I didn't hear a peep! (Didn't leave any mess either)
I'm a big believer in teens needing different sleep patterns.
Leave them alone and they will readjust eventually.
