It depends on how much time you give them. If you tell them to take the trash cans to the corner so the trash men can empty them, and it is now Wednesday, but the trash men don't come until Friday morning, then they have until Friday morning. If you tell them you want the trash cans up to the street in the next 30 minutes, then they have 30 minutes.
With my kids, if I told them to do something and it wasn't done, the consequences fit the job. If they were told to wash the dishes and they didn't, I'd find the dirtiest plate, glass, and silverware and that was theirs to eat off of. That kind of thing only happened once. The others learned and gained wisdom.
You have to be specific as to the time frame and your expectations. You have to make sure they understand the requirements.
In our house, they went to college or paid rent. The other alternative is to give them jobs to do with the understanding that if they didn't do their jobs and obey the rules of the house, they could always go and live under a bridge. and make up their own rules.
Good luck to you and yours.
