Can teens move out of their parents' home?

Yes what you do is make them become best friends with an different Adult and then make the adult ask them to move in. After that delete the adult and your teen can have there own home

Yes but I do not think teens can move out only adults.

Yes. You can make the teen have their own home, their last name sadly, will change.

1.
Build a home for your teen and move an Adult into the home.
2.
Make your teen become good friends or best friends with the Adult, the button 'Ask to Move in' should appear during these friendship stages.
3.
Your teen will now be moved in.
4.
Instead of deleting a sim, move them back into their original home by relocating, or repeating the steps above.

Hope this helped!

Or you can delete the parents 😂 Then the sim has that house

I wanted some of my teens to have their own house so I explored the game and found a way to do it (Note - only works if you have room for one more sim)
1. Add a new sim to an empty house. Their first name doesn't matter, but make sure the last name of your new sim is the same as your teen's last name (or whatever you want it to be).
Ex: My teen's name was Kelly Druce, so I named my new Sims PERSON Druce.

2. Send your teen to the new sim's house.

3. Do the "Be nice" option with each other until you are good friends.

4. Have the new sim ask your teen to move in,

5. Delete your new sim. (Note - if you want another teen to move in, too, make the other teen good friends with the new sim and have the new sim ask the other teen to move in before deleting the new sim. I used this to make 2 dating teens move in together.)

BOOM 💥! Your teen now has their own house and lives alone. I hope this was helpful. 😊

All you need to do is add an Adult sim to the house that you want your teen to move into. This adult sim needs to have the same last name as your teen if you don’t want the teen’s last name to change. You should then level up the friendship between the teen and new adult sim to at least good friend. This will then give the move in option; you should click this and the teen will move in with the adult. You can then delete the adult sim if you want or make it move out to have your teen live alone.

I just moved the household to the new house, divorced the parents, had mom move out, have dad go to moms, have dad and mom move back in together, not waste money on getting them married since they already have 2 kids, boom The Teens Now live all by themselves . Now I just got to Add My other teen in there and boom! Teens only house (Note this only works because the parents aren’t going to have more kids)
