Legal Question in Landlord & Tenant Law in Florida

There is no requirement under FL Law for notice of non-renewal of the lease. However, it is common for the lease itself to state that the lease may be renewed (or rarely will automatically will renew) upon written notice to the appropriate party. Your lease itself will also state the method by which any notice under the lease must be sent (usually in writing, delivered by certified mail or hand delivery). So, whatever your lease says governs.

Because you asked if you are required to do anything further, I will mention that after the tenant vacates the residence, you must follow procedure for returning/retaining the tenant's security deposit. See the helpful handbook at http://www.800helpfla.com/landlord_text.html.

Hope that helps.
