Some landlords have a provision against a sublease in the contract you sign, so read your own lease before doing something with another person. A sublease, or a sublease agreement, is when a landlord and tenant agree to rent out the unit to another resident not originally on the lease agreement.Tenants in Florida can sublease their rental property, but they need explicit written consent from their landlord. Here's some language for a sample letter requesting sublet permission. Use it in part or full when submitting your proposal. First, without prior notice to the landlord, it will be deemed illegal to sublet, and the landlord can evict both of you. A sublease agreement is drawn up in these situations, specifying key terms between you, the original tenant, and your friend, the subtenant. Owners please print out , fill out and return to Palm Beach Shores Town Hall. Florida landlords have the right to forbid a primary tenant from subleasing the property to another person unless subletting has been specifically agreed upon. If you're looking to get out of your lease early or make some money on an extra room, a sublease agreement may be an option for you.
