Unless the lease specifically addresses the topic, the tenant can sublet the premises without the landlord's permission. For subletting to be legal, the tenant must comply with the tenancy agreement, and usually, they require the landlord's permission for subletting to proceed.Subleasing is when your tenant allows another person(s), not on the original signed lease, to live in your rental property and cover the monthly rent payment. The lease will state whether or not he is allowed to sublet. If he does so without the landlord's consent, he is subject to eviction. A tenant may sublet a rental if no clause in the lease forbids it. Subletting is when thirdparty rents or "subleases" the property from the original tenant. Since Maryland has no explicit regulations governing subletting, the landlord will need to approve the new tenant. Maryland state law does not state whether residents can sublet without their landlord's consent. Most leases prohibit subletting, or only allow it with permission.
