What happens when one roommate gives a 30-day notice under a Month-to-Month Agreement and others want to stay?

If both roommates are on a Month-to-Month Agreement and one leaves, giving 30 days notice before doing so, the agreement becomes null and void 30 days from the day that they gave notice or on the day specified in the written notice. The following two options are available to the roommate who stays: 1. Find a new roommate and sign a new contract; 2. Give a separate 30-day notice of intention to move out. The owner or manager retains all the prerogatives available to him/her under any 30-day agreement.
