Late Rent Fee Limits in Florida

At a glance

What actually governs a Florida late fee

The Florida Residential Landlord and Tenant Act (Chapter 83, Part II) does not mention late fees. It contains no cap on the amount, no required grace period, and no rule about how or when a fee may be charged. In Florida the late fee is a matter of contract: it is lawful only if it is written into the lease, and its size is whatever the lease sets.

Two general limits still apply. First, § 83.46(1) makes rent "payable without demand or notice" at the start of each rent period, so unless the lease grants a grace period, rent is late the day after it is due and the lease's own timing controls when a fee attaches. Second, under § 83.45(1) a court "may refuse to enforce" a lease provision it finds "unconscionable at the time it was made," or "limit the application of any unconscionable provision as to avoid any unconscionable result." Florida courts also apply the ordinary contract rule that a charge which operates as a penalty, rather than a genuine estimate of the harm from late payment, is unenforceable. So a modest, clearly disclosed late fee is routinely enforced, while an extreme one can be struck down — but through these general doctrines, not a fixed statutory ceiling.

Because there is no statutory floor, the practical protections come from reading the lease before signing, negotiating the grace period and fee, and, if a fee is truly excessive, raising unconscionability or the penalty rule as a defense if the landlord tries to collect it or to use unpaid fees in an eviction.

What trips people up

The "$20 or 20%" number is for storage units, not homes. Many online summaries quote Florida's "$20, or 20 percent of the monthly rent, whichever is greater" late-fee figure as if it applied to apartments. It does not. That language is in § 83.808, which is Part III of Chapter 83 and governs self-service storage space. It has nothing to do with a residential dwelling, where no statutory cap exists.

There is no statutory grace period. Florida law does not give a tenant a set number of days before a late fee can be charged. If the lease says a fee applies the day after rent is due, that is enforceable. A grace period exists only if the lease creates one.

A fee still has to be reasonable to survive a challenge. "No cap" does not mean "anything goes." A late fee wildly out of proportion to the landlord's actual loss can be attacked as an unconscionable provision under § 83.45 or as an unenforceable penalty under general contract law.

Common questions

My lease charges $100 plus $10 a day. Is that legal in Florida? There is no statute making it illegal by amount. Whether it holds up depends on the lease and, if challenged, on whether a court views the charge as an unconscionable provision or a penalty rather than a real estimate of the landlord's costs.

Can the landlord charge a late fee if rent is one day late? Yes, if the lease provides for it. Section 83.46(1) makes rent due without notice, and Florida sets no minimum grace period, so the lease's timing controls.

Does a city ordinance set a different late-fee limit? Section 83.425 preempts local regulations on matters covered by the residential tenancy act, expressly including fees charged by the landlord and rental agreement terms.

If the court as a matter of law finds a rental agreement or any provision of a rental agreement to have been unconscionable at the time it was made, the court may refuse to enforce the rental agreement, enforce the remainder of the rental agreement without the unconscionable provision, or so limit the application of any unconscionable provision as to avoid any unconscionable result.

Official source: https://www.flsenate.gov/Laws/Statutes/2025/0083.45 (accessed 2026-07-20) - Fla. Stat. § 83.808(3) — the "$20 or 20%" reasonable late fee; part of the self-service storage law (Part III), NOT residential tenancies.

A facility or unit owner may charge a tenant a reasonable late fee for each period that he or she does not pay rent due under the rental agreement. ... For purposes of this subsection, a late fee of $20, or 20 percent of the monthly rent, whichever is greater, is reasonable and does not constitute a penalty.
