Florida Lease Extension: Notices, Deposits, and Month-to-Month

A Florida lease extension is a written addendum to your existing lease that pushes the end date forward while keeping every other term in place. It’s the cleanest way to keep a tenancy going in Florida, because the alternative — letting a fixed-term lease expire and staying put — turns you into a tenant at sufferance under Florida Statute 83.04, exposes you to eviction, and can cost you double rent under Statute 83.58.¹² Get the extension signed before the term ends, and the tenancy simply continues.

Extension or Renewal: Which One Do You Actually Want

People use these words interchangeably. Courts don’t. An extension is an addendum. The original lease stays in force, all its terms carry over, and only the end date changes unless the addendum specifically edits something. A renewal terminates the original contract and replaces it with a new one, giving both sides a clean slate to renegotiate rent, pet rules, maintenance duties, or anything else.

The difference matters if a dispute ever surfaces. With an extension, a court reads the original lease and the addendum together as one continuous agreement. With a renewal, the court reads only the new contract. If your current lease has terms you want to keep — favorable rent, a specific maintenance clause, a parking assignment — an extension is the safer route. If enough has changed that the old terms no longer fit, a renewal makes more sense.

What Goes in a Written Extension

A verbal understanding is not an extension. A proper written addendum should include:

The full legal names of every landlord and tenant on the original lease.
A reference to the original lease by signing date and property address, so there is no confusion about which agreement is being extended.
The exact start and end dates of the extension period.
A carryover clause stating that all other terms of the original lease remain in effect.
Any changed terms spelled out plainly, with a note that the new language replaces the corresponding clause in the original lease.
Signatures and dates from every party on the original lease.

The addendum becomes part of the original lease rather than standing on its own. Skip the reference to the original agreement and a court may treat the extension as an incomplete contract. Skip a co-tenant’s signature and that tenant can later argue they never agreed.

End-of-Term Notice Clauses Under 83.575

Before you sign anything, look at your current lease for a notice clause. Florida Statute 83.575 lets a fixed-term lease require the tenant to notify the landlord within a set window before vacating at the end of the term, but only if the lease also requires the landlord to give the same type of notice about whether it will be renewed. The notice window must be between 30 and 60 days.³

Miss that deadline and you can owe liquidated damages spelled out in the lease. There is one protection built in: the landlord must send you a written reminder at least 15 days before the notification period begins, listing every fee and penalty that applies if you miss the deadline.³ Without that reminder, enforcing the penalty becomes much harder.

There’s also a separate consequence for staying past the end date with the landlord’s permission but failing to give proper notice to end the resulting periodic tenancy: you owe an additional month’s rent.³ Read your lease. Calendar the notice window. Then decide whether to extend, renew, or move.

What Happens If You Don’t Extend Before the Lease Ends

This is the part Florida tenants and landlords miss most often. When a written fixed-term lease expires and the tenant stays without a new written agreement, Statute 83.04 treats the tenant as occupying the property on a tenancy at sufferance. Paying rent and having the landlord accept it does not create a renewed lease.¹ Only the landlord’s written consent to continued occupancy converts the situation into a tenancy at will governed by the periodic notice rules.

A tenant at sufferance sits in a weak position. Under Statute 83.58, the landlord can pursue eviction and recover double the monthly rent for every period the tenant refuses to surrender the unit.² If your rent is $1,800, the penalty runs $3,600 for each month you overstay. The statute doesn’t require a warning before the landlord seeks the double-rent penalty, and the landlord has no obligation to accept your regular rent payment once the lease has expired. Mail a check, and it can come back.

Because Statute 83.04 treats you as a holdover rather than a periodic tenant, the landlord isn’t required to give the notice periods that would apply to a month-to-month arrangement. The only reliable way to avoid this outcome is to sign an extension or renewal before the lease ends, or get the landlord’s written permission to stay.

Deposits Carry Over With an Extension

Because an extension leaves the original lease in force, your existing security deposit continues under the same terms. A renewal, by contrast, creates a new contract that can technically reset the deposit arrangement. Either way, Florida Statute 83.49 controls how the landlord holds the money — separate from personal funds, in one of the statutorily approved methods — and the landlord cannot use it for anything other than its intended purpose while you still occupy the unit.⁴ If a landlord asks for a new or increased deposit as part of a renewal, the same statutory protections apply to the additional funds.

If You Go Month-to-Month Instead

Not every situation calls for a full extension. If the landlord agrees in writing to let you continue after the term ends, the tenancy converts to a periodic one determined by how often rent is paid. Weekly rent creates a week-to-week tenancy, monthly rent creates a month-to-month tenancy, and so on.⁵

Either party can end a periodic tenancy by written notice within these minimum timeframes under Statute 83.57:⁶

Year-to-year: at least 60 days before the end of any annual period.
Quarter-to-quarter: at least 30 days before the end of any quarterly period.
Month-to-month: at least 30 days before the end of any monthly period.
Week-to-week: at least 7 days before the end of any weekly period.

The notice requirement applies equally to landlords and tenants and cannot be waived in the lease.¹ Miss the window and you’re bound for another rental period.

Delivering the Notices That Make Any of This Stick

Whether you’re giving notice of intent to renew, notice of non-renewal, or notice ending a periodic tenancy, the delivery method matters. Statute 83.56(4) recognizes four methods:¹

Standard mail to the other party’s address.
Hand delivery of a true copy to the other party.
Email, but only if both parties have agreed to electronic communication under Florida Statute 83.505.
Posting at the residence, but only when the tenant is absent from the premises.

A text message or a verbal conversation does not count. Certified mail with return receipt, or hand delivery with a signed acknowledgment, gives you the paper trail you’ll need if anyone later disputes what was said and when.

Active-Duty Military Can End the Lease Regardless

One category of tenant can walk away from a Florida lease without needing an extension conversation at all. Under the federal Servicemembers Civil Relief Act, a service member can terminate a residential lease after entering military service, receiving permanent change of station orders, or receiving deployment orders for 90 days or more. The service member delivers written notice with a copy of the military orders by hand, private carrier, or U.S. mail with return receipt requested. For monthly leases, termination takes effect 30 days after the next rent payment date following delivery.⁷

No early termination fee is allowed. Any prepaid rent for the period after termination must be refunded within 30 days, and dependents listed on the lease are released along with the service member. The tenant still owes prorated rent through the termination date, utilities, and any excess wear and tear.⁷
