You were fairer than you probably needed to be. Since she’s on a week-to-week lease, you theoretically could have evicted her one week after she defaulted. You definitely gave her more time than most other landlords would have.

Thank you very much

As the landlord, you don’t have to wait to evict anyone if the lease doesn’t require you to. Notice requirements typically are based on the frequency the rent is paid unless the lease agreement states otherwise. (If she pays month-to-month, you’d have to give a month’s notice. If she pays week-to-week, only a week’s notice.) I’d recommend speaking to her about it first and making it clear that she is not to advertise under any name other than her own, nor misrepresent herself as the business owner in any capacity.

All you should have to do is enforce the contract she signed. Whatever the penalties are for early termination–enforce them. If she fails to comply, you’ll want to file in small claims court. There are no laws specific to sublet tenancies in most jurisdictions, so this is a contract law issue. In the absence of any evidence proving the contract wasn’t valid, she will be expected to stick to the agreement she made.

Give her a written notice, letting her know that you won’t be renewing her week-to-week agreement. You don’t have to explain why, and really, you probably shouldn’t. If she asks, just tell her that the decision has been made.

If you want timely responses, I suggest either becoming a VIP member or scheduling a consulting appointment. I reply to comments when I have the availability.
