Legal Question in Landlord & Tenant Law in Maryland

You will need to check the specific language of your lease. Any well-written lease should describe whether renewal is automatic or not and identify what the parties need to do to communicate non-renewal (how many days advance notice needs to be given, etc.).

In Maryland, you can call the non-profit organization Baltimore Neighborhoods Inc to get answers to general landlord/tenant questions along with some literature. Because tenants have certain rights under the law and you need to appropriately deal with the security deposit and final inspection or face legal damages, you may find it helpful to consult with an attorney before taking action.
