The current renters are trying to sublet it without the landlord knowing. Subletting is not always allowed.Our leases specifically prohibit it without landlord permission. Can I get in trouble if I sublease without my landlord's permission? Yes. Subleasing without your landlord's permission may violate your lease. Here's some language for a sample letter requesting sublet permission. Use it in part or full when submitting your proposal. The lease says you will need your landlord's permission to sublet, so I would start there. Talk to them about the situation and get their consent. Yes. Not only is it legal, but in certain situations the landlord has an obligation to enter without permission, such as in a emergency.
