Florida required lease disclosures: the radon line, the deposit notice, your address and the flood form
Four Florida statutes govern what a landlord must say at or near signing: the radon sentence in s. 404.056(5), the deposit notice in s. 83.49(2), the address disclosure in s. 83.50 and, for terms of a year or longer, the separate flood disclosure in s. 83.512. Each has its own deadline and wording.
The four disclosures in one table
| Disclosure | Section | When |
|---|---|---|
| Radon gas paragraph | 404.056(5) | On at least one document executed at or before the rental agreement |
| Landlord name and address | 83.50 | In writing, at or before the start of the tenancy |
| Deposit and advance rent notice | 83.49(2) | In the lease, or within 30 days after receipt |
| Flood disclosure | 83.512 | At or before signing a rental agreement for a term of 1 year or longer |
What is the radon requirement?
Section 404.056(5) says notification must appear "on at least one document, form, or application executed at the time of, or prior to," the execution of a rental agreement for any building. The text begins "RADON GAS: Radon is a naturally occurring radioactive gas that, when it has accumulated in a building in sufficient quantities, may present health risks to persons who are exposed to it over time," continues that levels above federal and state guidelines have been found in Florida buildings, and tells readers to ask the county health department about testing. Stays out: transient occupancy of 45 days or less.
How do you disclose where the deposit is held?
Section 83.49(1) requires you to hold the money in a separate non-interest-bearing account in a Florida financial institution, a separate interest-bearing account, or under a surety bond with the clerk of the circuit court. Subsection (2) then requires written notice, in the lease or within 30 days after receipt of the money, that gives the name and address of the depository or states that a bond was posted, says whether the tenant is entitled to interest, and contains the statute's printed paragraph on how a claim against the deposit works. It must be given in person or delivered by mail or e-mail under s. 83.505. Change the account's location and you have 30 days to notify the tenant, though a bank merger or name change does not require new notice.
The subsection does not apply to a landlord who rents fewer than five individual dwelling units. Failure to give the notice is not a defense to the payment of rent when due.
Example a made-up Jacksonville owner with eight units takes a $1,800 deposit on March 3. The lease does not carry the notice, so the written deposit notice has to be delivered by April 2, which is 30 days after receipt.
What does section 83.50 add?
The landlord, or a person authorized to sign for the landlord, discloses in writing at or before the start of the tenancy "the name and address of the landlord or a person authorized to receive notices and demands in the landlord's behalf." That person keeps authority until the tenant is told otherwise. Changes must be delivered to the tenant's residence, or another address the tenant names in writing, or sent by e-mail under s. 83.505.
Who needs the flood form?
Section 83.512(1): a landlord "must complete and provide a flood disclosure to a prospective tenant of residential real property at or before the execution of a rental agreement for a term of 1 year or longer," in a separate document in substantially the statute's form. It states that renters' policies do not cover flood damage and asks whether the landlord knows of flooding that damaged the unit during ownership, has filed a flood insurance claim, or has received assistance such as FEMA aid, and defines flooding.
If you violate the section and the tenant suffers substantial loss of personal property to flooding, the tenant may terminate by written notice within 30 days of the loss (subsection 2). "Substantial" means repair or replacement cost of 50 percent or more of the property's market value.
How DoorKeeping helps in Florida
DoorKeeping keeps the lease, the move-in report and the deposit details together for each unit, so you can ask Claude or ChatGPT which disclosures a lease is missing before you send it. Anything that goes to a tenant waits for your one-tap approval. DoorKeeping never holds your money and sends a payment only when you approve it. This is general information, not legal advice: check the current statute and your own lease.
