Set rules and boundaries from day one!

Everyone cleans the apartment, bathroom, kitchen, etc, 2-3 times per week. Make a roster if you have to.

Every one does dishes, no excuses!

After 9pm, no loud sounds of any kind, unless three of you are watching a movie together. Otherwise, put on headphones.

There was one night, 2 of my roommates decided two fuck random girls at 2am and the girls were loud! Not going to lie, I was a bit jealous at the time, but my sleep was more important. So establish ground rules for guys staying over.

If you notice one of your roommates has a habit of leaving a dirty plate on a coffee table, point it out and nip it in the butt asap.
