Florida Lease Extension: Agreements, Notices, and Deposits

A Florida lease extension is a written addendum that moves the end date of your existing lease forward while keeping every other term in place. Signing one before your current lease expires is the only reliable way to stay in the unit without renegotiating from scratch and without exposing yourself to the penalties Florida law attaches to holdover tenants. Skip the paperwork and keep paying rent, and you are not quietly on a month-to-month — you are a tenant at sufferance, and your landlord can pursue eviction and recover double rent for every period you remain.¹

Extension or Renewal: Which One Do You Actually Want

These words get swapped in conversation, but they produce different contracts. An extension is an addendum. The original lease stays in force, the expiration date moves, and every clause carries over unless the addendum changes something specific. A renewal terminates the old lease and replaces it with a new one, which gives both sides a clean slate to rework rent, pet rules, maintenance responsibilities, or anything else.

Extensions suit shorter add-on periods and situations where the existing terms still work. Renewals suit longer commitments or changed circumstances. The distinction matters if a dispute lands in court: with an extension, a judge reads the original lease plus the addendum as one continuous agreement; with a renewal, only the new contract applies. If the original lease contains terms you want to preserve, the extension route is safer.

What a Florida Lease Extension Agreement Should Contain

A verbal agreement to “keep things going” is where disputes come from. Put the extension in writing and cover each of these items:

Full legal names of every landlord and tenant listed on the original lease.
A reference to the original lease by signing date and property address, so there is no question which contract is being extended.
The exact start and end dates of the extension period.
A statement that all other terms of the original lease remain in effect.
Any changes being made, such as a rent increase, along with language noting the new provision replaces the corresponding clause in the original lease.
Signatures and dates from every party who signed the original lease.

The addendum becomes part of the original lease rather than a standalone document. If it fails to reference the original lease, a court may treat it as an incomplete contract. If only some tenants sign, the ones who did not can argue later that they never agreed to the new terms.

End-of-Term Notice Clauses Under Florida Statute 83.575

Many Florida leases contain a clause requiring the tenant to notify the landlord in advance about whether they intend to leave at the end of the term. Florida Statute 83.575 permits these clauses, but only when the lease also requires the landlord to give the tenant the same type of notice about whether the lease will be renewed, and the notice window must fall between 30 and 60 days before the end date.²

If your lease contains this kind of clause and you miss the deadline, you could owe the liquidated damages the lease spells out. There is a protection built in: the landlord must send a written reminder at least 15 days before the notification period begins, listing every fee and penalty that would apply if you miss the deadline.² Without that reminder, enforcing the penalty becomes much harder for the landlord.

One more detail from the same statute: if you stay past the end date with the landlord’s permission but fail to give proper notice to end the resulting periodic tenancy, you owe an additional month’s rent.² Read your lease’s end-of-term clause well before the expiration date and act within whatever window it sets.

What Happens if the Lease Just Expires

This is the part of Florida law that surprises people. Under Florida Statute 83.04, when a written fixed-term lease expires and the tenant stays without signing a new written agreement, the tenancy becomes a tenancy at sufferance. Paying rent and having the landlord cash the check does not create a renewed lease on its own.¹ Only the landlord’s written consent to continued occupancy converts the situation into a tenancy at will governed by the periodic-tenancy rules.

The cost of staying without that consent is spelled out in Florida Statute 83.58: the landlord can pursue eviction and recover double the monthly rent for every period the tenant refuses to surrender the unit.³ If your rent is $1,800, that is $3,600 per month. The landlord does not have to warn you first and does not have to accept your regular rent payment. If you mail a check and it comes back, you have not bought any time. The double-rent exposure accumulates from the day the lease ended through the day you actually move out, and because the tenancy is at sufferance, the landlord does not have to wait out the notice periods that apply to month-to-month arrangements.

The way to avoid all of this is simple: sign an extension or renewal before the lease ends, or get the landlord’s written permission to stay.

If You Want to Go Month-to-Month Instead

If the landlord agrees in writing to let you stay without a new fixed term, you shift into a periodic tenancy. The type is set by how often you pay rent: weekly payments create a week-to-week tenancy, monthly payments create a month-to-month tenancy, and so on.⁴ Either party can end a periodic tenancy with written notice, but the notice has to arrive within these minimum windows:⁵

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.

Miss the window and you are effectively locked in for another rental period. The notice requirement cannot be waived in the lease.¹

How to Deliver a Notice That Actually Counts

Florida Statute 83.56(4) lists the delivery methods that satisfy the law for termination and non-renewal notices:¹

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

A text message or a hallway conversation does not count. Certified mail with return receipt, or a certificate of mailing, creates a paper trail. If you hand deliver, ask the other party to sign an acknowledgment of receipt and keep a copy.

Your Security Deposit During an Extension

Because an extension keeps the original lease in force, your original security deposit carries forward on the same terms. A renewal, by contrast, creates a new contract and can technically reset the deposit arrangement. Regardless of which path you take, the landlord cannot commingle your deposit with personal funds or spend it while you still occupy the unit.⁶ If a landlord tries to collect additional deposit money at renewal, the same statutory rules apply to the new funds. Ask in writing which holding method the landlord uses, and keep the confirmation with your copy of the extension.

Protections That Still Apply

Even if your lease has lapsed and the landlord wants you out, self-help eviction is illegal. Under Florida Statute 83.67, a landlord cannot shut off utilities, change the locks, remove doors or windows, or take any similar action to force you out without a court order. A tenant harmed by any of these tactics can recover actual damages or three months’ rent, whichever is greater, plus attorney’s fees and court costs, and each separate violation triggers its own damages award.⁷ These protections cover holdover tenants as well as tenants mid-lease.

Military tenants have a separate off-ramp. Under the Servicemembers Civil Relief Act, a service member can terminate a residential lease without penalty after entering military service, receiving permanent change of station orders, or receiving deployment orders of 90 days or more. The service member delivers written notice with a copy of military orders, and for leases with monthly rent the termination takes effect 30 days after the next rent due date following delivery. The landlord cannot charge an early termination fee, must refund rent paid in advance for the post-termination period within 30 days, and the termination also releases dependents listed on the lease. The service member still owes prorated rent through the effective termination date along with utilities and any excess wear.⁸
