What Is the New Security Deposit Law in Florida

If you rent in Florida and you’re wondering what happens to your security deposit after a lease ends, the rule people keep referencing usually comes down to two themes: renewals and timing. Florida-law summaries describe carried-forward deposits during a renewal as being treated like a new security deposit, which affects both how much can be kept and what notice a landlord has to give.

Below is a plain-English FAQ built around the renewal/new-deposit rule, the 30-day written notice requirement, and the timing themes described as 15/30/15.

Security deposit renewals in Florida: carried-forward deposits treated as new (1 month limit)

Here’s the core “new law” idea that shows up in Florida law summaries:

• If you renew your lease and your landlord says your existing security deposit will be carried forward, Florida summaries say that carried-forward deposit is treated as a new security deposit.
• That carried-forward (now “new”) security deposit is limited to 1 month’s rent.

So even if you already paid a deposit during your original move-in, the renewal can’t keep treating that money as the same deposit forever. Florida summaries frame it as a deposit being held under the renewed lease, with a cap at one month’s rent.

Quick renter scenario

If your original deposit was paid for your first lease term, and then you renew, the landlord generally can’t use the carried-forward amount as a way to exceed the 1-month cap that applies to the “new” deposit for the renewal.

(If you’re unsure how this applies to your exact lease terms, it’s smart to check the lease and confirm the details with the Florida statutes or a qualified tenant attorney.)

How much can a landlord collect: the one-month rent limit shown in the 2025/2026 snippets

Florida law summaries also emphasize the one-month cap for what a landlord collects up front:

• The initial security deposit a landlord collects before move-in is limited to a maximum of one month’s rent.

And, as mentioned above:

• Any carried-forward deposit treated as a new security deposit is also limited to 1 month’s rent.

So when you see “new law” references online, they usually point back to the same basic math:

• One month of rent is the cap (for the initial deposit before move-in and for renewal/carry-forward situations treated as new).

Move-in and deposit handling timelines: the 15-day and 30-day themes in Florida law summaries

Florida deposit rules in summaries are often explained using timing windows tied to what happens after you move out and when the landlord provides notice.

Two themes show up repeatedly:

1. A “15/30/15” style timeline for claim and return actions.
2. A 30-day written notice requirement explaining what the landlord kept and why.

Even if you don’t treat this like a legal checklist, it’s a useful way to think about the flow:

• The landlord has to follow claim/return windows tied to key handoff and when the tenant vacates.
• The landlord then has to send written notice within 30 days, explaining what was kept and why.

How to connect this to your timeline

If you’re moving out, the key dates to keep track of are:

• When keys are handed over
• When you’re fully moved out
• When your landlord sends written notice
• When you receive a refund (if any)

If a landlord is late, or if they only explain the damage after missing notice requirements, that’s often a red flag based on the timing and notice themes reflected in the summaries.

Written notice requirements: what must be provided within 30 days and how it’s delivered

One of the clearest requirements in Florida law summaries is about written notice.

Florida summaries say the landlord must provide written notice within 30 days that includes:

• how much of the deposit will be kept
• why they are keeping that amount

This matters because the rule isn’t only about whether a landlord can keep money. It also requires a written explanation within that 30-day window.

How it should be delivered

Florida summaries focus on the fact that it must be written notice—not just a verbal explanation.

If you want to protect yourself, save proof such as:

• email or mail logs
• the date you received any letter
• screenshots of any posted or emailed notice

If you didn’t receive written notice, that’s a common dispute point, because the “within 30 days” requirement is one of the recurring themes in the summaries.

How long can a landlord keep a deposit in Florida? claim/return timing explained from the snippets

People usually ask, “How long can they keep my deposit?” because they want to know when they’ll see their refund.

Florida law summaries describe timing using 15/30/15 themes, with the notice requirement landing at 30 days.

While the exact day-by-day steps can vary based on the situation and how the claim/return process works in the statutes, the overall takeaway from the summaries is:

• The landlord can’t just hold the money indefinitely.
• The landlord’s process should follow claim timing, then a return/notice window that fits the 15/30/15 framing.
• The landlord must also provide written notice within 30 days that explains what they kept and why.

If your landlord claims damages

Expect the claim process to fit the timing windows described in the summaries. If the landlord delays the explanation or sends it outside the notice window, that’s exactly the kind of “notice/timeline” problem these summaries highlight.

When a landlord can offer a fee in lieu of a security deposit (Chapter 83 Section 491)

Sometimes you’ll see landlords avoid using the phrase “security deposit” and instead offer something else.

Florida summaries reference Chapter 83 Section 491 (2024 Florida Statutes) and describe an option:

• If the rental agreement requires a security deposit, the landlord may offer the tenant the option to pay a fee in lieu of a security deposit.

So the “fee in lieu” idea is basically an alternative structure under that same Chapter 83 section. If your lease uses this option, read it closely so you understand what you’re paying and what the move-out and claim process looks like.

(Again, this is based on what the summaries say. If your landlord calls it a “fee” instead of a deposit, you still want to understand the exact terms and how the move-out notice/claim process should work.)

Can a landlord ask for first and last month rent plus security in Florida?

The renewal/new-deposit rule and the one-month cap are covered in the Florida law summaries reflected here, but the provided research doesn’t include a snippet-based, direct answer to whether “first + last + security” is allowed in every situation.

What the snippets do emphasize clearly is:

• The initial security deposit collected before move-in is limited to one month’s rent.
• Any carried-forward deposit treated as a new security deposit is also limited to one month’s rent.

So while the “first + last + security” question can’t be confirmed from the provided research, you can still sanity-check the security-deposit part:

• If the “security deposit” amount is more than one month’s rent, that’s where the summaries suggest you should be cautious.

For a clear answer on your specific charges, compare the security deposit line in your lease to the one-month rent cap described in the Florida summaries.

What is illegal for a landlord to do in Florida? (what the snippets emphasize)

Based on the themes in the summaries you referenced, the common “illegal” or non-compliant patterns to watch for are the ones tied to:

1) Ignoring the one-month limit

Florida summaries emphasize that:

• Initial move-in security deposits are limited to a maximum of one month’s rent
• Renewal carry-forward deposits treated as new are limited to one month’s rent

So trying to collect more than that for a security deposit (including in renewal scenarios treated as new) is a key problem reflected in the snippets.

2) Treating renewals incorrectly (carried-forward as “not new”)

The renewal rule says the carried-forward deposit is considered a new security deposit.

So if your landlord treats your carried-forward deposit like it’s not subject to the “new” rules, or if the landlord’s handling breaks the 1-month limit, that’s the renewal-related conflict the summaries highlight.

3) Missing the 30-day written notice requirement

Florida summaries say the landlord must provide written notice within 30 days that explains:

• how much was kept
• why it was kept

So if you don’t get that written notice within 30 days, or if it doesn’t explain what was kept and why, that’s another compliance failure emphasized in the summaries.

4) Holding the deposit outside the claim/return timing themes

The snippets reference 15/30/15 timing ideas.

If the landlord drags things out or can’t align the actions with the notice/timing windows, that’s another pattern the summaries warn about.

(And remember: the exact timing mechanics can depend on the facts of your move-out, key return, and the lease terms. Use the timelines as a “does this seem reasonable?” check, not as a replacement for reading the statute.)

What to do if you receive a notice of intention to impose claim on security deposit

If you receive a notice that your landlord intends to take money from your security deposit, don’t panic. Do respond with a plan like this:

Step 1: Compare the notice to the 30-day written notice theme

Florida summaries emphasize that written notice within 30 days should explain:

• how much will be kept
• why it’s being kept

Check that both items are included. If key details are missing, write down what’s absent.

Step 2: Match your notice date to your move-out/key date

Since the summaries use 15/30/15 timing themes, write down:

• the date you returned keys or gave possession
• the date the notice arrived, or when you received it

If the timing looks off, that can matter in a dispute.

Step 3: Keep proof of the condition of the unit

Even though this guide doesn’t provide legal strategy, it’s still smart to gather basic evidence:

• move-in photos/videos (if you took them)
• move-out photos/videos (if you took them)
• receipts for any repairs or cleaning you paid for
• emails/messages with the landlord about issues before move-out

Step 4: Don’t wait on the refund timeline

Because the summaries describe claim/return timing using the 15/30/15 idea, keep an eye on when you actually receive money back (if any).

If the landlord keeps money but delays the explanation or refund in a way that doesn’t match the notice-and-timing themes, that’s the kind of mismatch reflected in the summaries.

Step 5: If you’re still stuck, verify with the statutes or a tenant lawyer

This guide is based on the Florida-law themes summarized here, not legal advice. If money is at stake and the notice seems wrong, a qualified attorney can help you apply the timing rules to your specific situation.

If you’re dealing with a deposit issue, use this quick checklist

• Does the deposit cap look right? The summaries say the security deposit is up to 1 month’s rent. Renewal “carried forward” deposits are treated as new and also limited to 1 month.
• Did you get written notice within 30 days? It should say how much was kept and why.
• Do the dates line up? Compare your move-out/key return date to the notice date and the 15/30/15-style timing themes from the summaries.
• Does the notice of claim explain the amounts clearly? If it’s vague, that’s a problem the summaries warn about.
• Are you dealing with a “fee in lieu” instead of a deposit? Chapter 83 Section 491 (2024) describes an option for a fee in lieu of a security deposit, so check how your lease is set up.

If you run your situation through that list and something doesn’t fit—especially the 30-day written notice or the one-month limit—that’s usually where you start looking more closely at what your landlord did and what the Florida summaries say the rules are.
