Roommate's Partner Moved In Unannounced

It starts innocently with a few nights a week. Then it is every night. Then their stuff is in the bathroom, their food is in the fridge, and they are using utilities without contributing. You now have an extra roommate you did not agree to.

The problem is a roommate's partner is staying over so frequently they are essentially living in your home without being on the lease, without paying rent or utilities, and without agreeing to house rules. This affects your privacy, finances, and comfort.

Check your lease first. Most leases specify who can live in the unit and have guest stay-over limits. If the partner is there beyond the allowed number of nights, your roommate may be violating the lease which puts everyone at risk.

Have the conversation directly. Say you have noticed their partner has been staying over a lot and you are not against it, but if they are going to be living there you need to discuss how it affects rent, bills, and house rules.

Propose solutions where if they stay more than 3-4 nights per week consistently they should contribute to rent and utilities proportionally. Update the roommate agreement to include clear expectations about regular guests.
