Tenants generally can't sublet their unit without the landlord's consent. Protect your rentals with Avail lease agreements and amendments.Some Florida leases include a clause that bans subletting unless the tenant has gotten the landlord's explicit permission. I have a friend which is "subletting" an apartment (as the sublet tenant, Person B). Apparently the tenant (Person A) cannot sublet per its contract. If you have a lease for a set term, like one year, you can sublet with or without your landlord's permission, unless they prohibit this in the written lease. In Florida, subletting is allowed. However, a tenant will not be permitted to sublet a rental apartment if the primary lease agreement forbids it. Depending on the lease agreement the landlord can evict if it was detailed no subleasing. You will need the subtenants to vacate. As of this writing, Florida law does not discuss subletting in any way, which means that there is no legal bar to the practice.
