Do I have to tell my landlord I am moving if I have a written lease?
No.
Your lease sets forth the date on which it ends, and you are supposed
to move on that date unless you and your landlord agree to renew your
lease agreement.
What if I do not have a written lease?
If
you pay rent on a monthly basis, you must give your landlord 30 days
written notice that you are moving out. Otherwise, you can be held
liable for another month's rent. If you pay rent on a weekly basis, you
give your landlord 7 days written notice that you are moving.
Otherwise, you can be held liable for another week's rent. For more
information, see the Leases and Subleases Guide.
