In Florida, residential leases of any duration are acceptable. An oral lease agreement is legal and enforceable for any period of less than one year. Lease agreements that exceed one year are permitted, but they must be in writing to comply with the statutes of fraud concerning property transactions.
The maximum length of a standard residential lease agreement in Florida is generally one (1) year. However, a lease may be longer than one year if it meets additional legal requirements.
For leases longer than a year to be legally enforceable, they need to be in written (not oral) form. Additionally, it is recommended that the landlord sign the lease in the presence of two subscribing witnesses to ensure legal enforceability.
