How to Write a Security Deposit Demand Letter in Florida

A security deposit demand letter is a written request that formally asks your landlord to return your deposit, cites the law they violated, and warns that you'll take the matter to court if they don't pay. In Florida, sending one before you file is smart: it creates a paper trail, it often gets you paid without a lawsuit, and it shows any future judge that you gave the landlord a fair chance to make it right. The key is to be firm, specific, and grounded in Fla. Stat. § 83.49, not angry.

I've written a lot of demand letters in my own Florida consumer disputes, and the ones that work share a pattern: they're calm, they cite the exact statute and deadline the other side missed, and they make clear you know your rights and are ready to act. That combination is far more persuasive than threats.

When to send it

Send your demand letter after the landlord's deadlines under § 83.49 have passed. As a reminder from our main guide on getting your deposit back: the landlord has 15 days after you vacate to return the full deposit, or 30 days to send proper written notice of a claim against it. Once day 30 passes with no proper notice, the landlord has generally forfeited the right to keep any of your deposit, and that's exactly when a demand letter lands hardest.

What to include in the letter

A strong Florida security deposit demand letter has these parts:

Your information and the landlord's. Your full name and current forwarding address at the top, the landlord's or property manager's name and address, and the date.

The property and tenancy details. The rental address, the date your lease began and ended, the date you vacated and returned possession, and the amount of your security deposit.

The statutory violation. State plainly that under Fla. Stat. § 83.49, the landlord was required to return your deposit within 15 days or send written notice of a claim within 30 days, and that they failed to do so. If they missed the 30-day notice deadline, say so directly and note that they have therefore forfeited the right to impose any claim.

The demand. Clearly state the exact amount you're owed and request its return by a specific date, a firm but reasonable deadline, such as 10 to 15 days from the date of your letter.

The consequence. Note that if they don't return your deposit by that date, you'll file in small claims court, and that under § 83.49(3)(c) the prevailing party is entitled to court costs and reasonable attorney's fees. That last point is often what moves a landlord to pay.

How to send it

Send the letter by certified mail with return receipt requested, and keep a copy of the letter and the mailing receipt. The certified receipt proves the landlord received your demand and the date they got it, which matters if you end up in court. Sending a copy by email as well is fine, but the certified mail is your proof.

A simple template outline

You can adapt this structure:

Your name and forwarding address / date
Landlord's name and address
"Re: Demand for Return of Security Deposit, [rental address]"
One paragraph stating the facts: when you moved out, the deposit amount, and that no proper deposit return or § 83.49 notice was sent within the statutory deadline
One paragraph stating the law: § 83.49's deadlines and the forfeiture of any claim
One paragraph making the demand: the exact amount and a specific response deadline
One paragraph on consequences: small claims court and the attorney's-fee provision
A closing line and your signature

Keep it to a single page. Judges and landlords both respond better to a letter that is clear and professional than to one that is long or emotional.
