A tenant can sublet without the landlord's permission, even if the lease says its forbidden. If your landlord decides to deny your sublet request, the denial must be reasonable.Your landlord cannot unreasonably withhold consent to sublease. Our firm helps landlords evict tenants for failing to pay rent, lease violations, property damage, overstaying, and illegal or disruptive behavior. Generally, landlords have a right to include a "no pets," provision in the lease agreement. A tenant may not assign the lease without the landlord's written consent. The landlord may withhold consent without cause. An oral agreement is made between the landlord and tenant after they discuss rental items. It is usually a month to month agreement – that is, the rent is paid.
