How to Set a Fair Roommate Guest Policy

Your roommate's partner showers at your place, eats your food, and has been on your couch for 3 weeks. They don't pay rent. Here's how to set guest rules — before it becomes a fight.

1. Define "Guest" vs "Resident"

The big question: at what point does a guest become an unofficial roommate? Most agreements set a monthly limit — 3-5 nights per month is common. More than that, and they should be contributing to utilities or rent.

2. Notice Requirements

Do you need to tell your roommates before having someone over? For a quick coffee, probably not. For an overnight guest or a party? Yes — at minimum a heads-up in the group chat. Your agreement should specify the threshold.

3. Party Rules

How many people is "a few friends" vs "a party"? Set a number. 5-10 guests = heads-up required. 10+ = all roommates must agree. This prevents the "I didn't know it was a problem" defense.

4. Quiet Hours for Guests

Guests should follow the same quiet hour rules as roommates. If quiet hours start at 10 PM, guests should leave or keep it down by then — especially on weeknights when someone has an 8 AM class.

5. Parking and Shared Spaces

Does your guest take the last parking spot? Use the shared bathroom for 45 minutes? Small things that cause big resentment. Address them upfront.
