Thank you very much free9man for your kind attention and time.

The original lease is from over 20 years ago.

It was originally a 6-month lease.

Regarding termination, the lease agreement says the following:

In the event Tenants intend to vacate the premises on expiration of the term, they must give the Owner at least 30 days written notice of such termination, otherwise such tenancy shall automatically become a month-to-month tenancy upon the same terms and conditions expressed herein.

Owner may give Tenants at least 30 days written notice that Owner will not allow Tenants to remain on a month-to-month basis upon the expiration of this term.
Since the expiration of the lease over 20 years ago, I have always stayed at the apartment on a month-to-month basis.

Would the above have any impact on my situation, and could it possibly give me any right to ask my roommate to leave?

If so, I would greatly appreciate hearing your thoughts and advice. Thank you!
