I wouldn't be paying him to do everyday things he should be doing regardless of where he lived.

If his bed isn't made, clothes not in the washing basket, towels not hung up, then he doesn't leave the house until they are. No money involved, simply being a part of a household. No lifts anywhere, because he isn't going until his things are tidy and his chores done.

Pocket money in my home was a privilege, not a right, and not payment for participating in my own life - ie making my bed.

If it were me, it would be a sit down serious discussion about expectations and being old enough to do chores, exactly what he is expected to do without prompting, and being a part of a family/household. Until he can manage that, then how do you trust him to carry himself in a decent manner when out of your supervision? If that requires your DH standing there when he gets out of the shower and telling him to hang up the bathmat for a week so he gets the picture, then that is what it takes.
My 5 year old makes her own bed, puts her own clothes in the washing basket, puts them away when they are clean and gets herself dressed everyday, it is part of living her life and it is what is expected of her, I don't pay her to do it. I think that sends the wrong message. That one only need do these things if there is an immediate and physical reward for doing them and that is just not the case in my house. FWIW, I know she is not a teen, but she does get pocket money and she does do her chores, and neither is dependent on the other, and they are never used to encourage or prompt for the other, itms.

Anwyay, good luck, I hope you can work something out before bub comes!
