Mine aren't allowed to eat in their rooms, therefore I don't have to worry about mouldy plates or crumbs attracting mice etc. This is IMO key to a harmonious relationship with teens, because it means its possible to say that their rooms are completely up to them - never ever tidy or clean a NT teen's room for them, but also never, ever nag them to do it. Their own room is their own responsibility and you don't get involved.
Washing gets washed if its in the basket but you never ever concern yourself with washing which might land on their floordrobe...
My three (11, 14, 16) do the dishwasher and kitchen and outside bins on a rota which they police between themselves.
They clean out the guinepigs together (a condition of getting them two years ago which they've never broken).
They all put their own laundry away (we have a basket each - we're lucky and have a utility room, so baskets stay in there until they carry theirs up).
They bring their own dirty laundry or communal laundry if they put theirs in there down after emptying their clean basket.
16 year old mostly does her own laundry asshe likes it straight away, but doesn't have to - if she puts it in the communal laundry she gets it when I've had a chance to do it.
They can all operate the washing machine and 14 year old washes his team's sports kit when its our family's turn - no earthly reason this should be anyone else's job.
I work shifts and when I'm on a late either the 14 and 10 year olds cook together (they get on really well) or 16 year old cooks, or DH cooks. Its not set in stone but depends on the meal - the younger two specialise in home made pizza and things from the freezer with home made chips... basically cooking gives you power to overrule the meal plan, so has appeal...
