How Much Can a Landlord Raise the Rent in Florida?   The amount
that a landlord can legally raise your rent in Florida depends
on the lease. If you are still within your lease, then your
landlord is not allowed to raise your rent until your lease is
over. However, some landlords will specifically put on the lease
that rent increases can happen, and in these cases a landlord
can legally raise your rent as much as they want to, there is no
maximum limit. They have to give you at least a 30-day advance
written notice about the increase.
