Florida Tenant Security Deposit Recovery Calculator

How this calculator works

Florida residential security deposits are governed by F.S. § 83.49 (Florida Residential Landlord and Tenant Act). Unlike the substantive question of whether the landlord can charge the tenant for a specific item of damage, deposit recovery is dominated by procedural facts. A landlord who skips the 30-day claim notice, misuses certified mail, or sends a vague reason forfeits the right to claim by operation of statute — no matter how clean the underlying damage claim looks on the merits. For the tenant, the deposit-return framework is one of the most consumer-favorable corners of Florida residential landlord-tenant law because the procedural strictures are unforgiving and the fee-shifting provision under § 83.49(3)(c) flips the cost-of-litigation calculus.

The calculator projects a Florida deposit dispute end-to-end from any procedural stage. The five headline outputs:

1. Timeline status. Where the dispute sits on the § 83.49(3) procedural ladder — within the 15-day no-claim return window, in the 30-day claim-notice window, in the 15-day tenant-objection window, past the objection window with no objection, in pending litigation after a tenant objection, or in statutory forfeiture.
2. Tenant's recoverable amount. The dollar amount the tenant can lawfully recover under the current posture. A properly-perfected claim reduces the recoverable amount by the claim; a defective claim restores the full deposit.
3. Procedural compliance verdict. Compliant, Defective — Forfeited, or Pending. The headline judgment on the landlord's adherence to § 83.49(3).
4. Recommended next step. Concrete next action for the tenant — wait for the return, send a certified-mail demand, file a written objection, or file a small-claims action under the fee-shifting provision.
5. Summary. A synthesizing narrative that pulls the timeline status, the compliance verdict, the claim amount, and the prevailing-party fee-shifting framework into a single decision-grade output.

The F.S. § 83.49 framework

The Florida deposit-return statute operates on three controlling windows:

• 15-day no-claim return (F.S. § 83.49(3)(a)). If the landlord makes NO claim against the deposit, the landlord must return the full deposit within 15 days of vacancy. No notice to the tenant is required; the obligation is simple repayment. A landlord who lets the 15-day window lapse without returning the deposit and without sending a claim notice is in default of the statute — the tenant recovers the full deposit plus attorney's fees in any action to enforce.
• 30-day claim notice (F.S. § 83.49(3)(b)). If the landlord intends to claim against the deposit, the landlord must send the tenant a WRITTEN claim notice within 30 days of vacancy specifying the amount and reason. The notice must be sent by certified mail to the tenant's last known mailing address. Email, text, regular mail, and oral notice are all defective. Missing the 30-day deadline forfeits the right to claim against the deposit by operation of statute — there is no good-cause exception, no extension for partial compliance, and no relief for inadvertent oversight.
• 15-day tenant-objection window (F.S. § 83.49(3)(c)). Once the landlord sends a proper claim notice, the tenant has 15 days from receipt to object in writing. Silence operates as a statutory waiver — failure to object means the landlord may deduct the full claim and must return the balance within 30 days after the objection period closes. An objection forces the landlord either to file a civil action within 30 days to enforce the claim or to return the full deposit.

The three windows compose into a strict procedural ladder. Each window has its own forfeiture rule; missing one does not always cure missing another. The calculator surfaces the controlling window for the current posture and reports the day count against the statutory limit.

Holding requirements under F.S. § 83.49(1)

Beyond the return-and-claim framework, F.S. § 83.49(1) imposes account-level holding requirements. The landlord must hold the deposit in one of three ways:

1. Separate non-interest-bearing Florida account containing only security deposits and advance rents. No commingling with operating funds.
2. Separate interest-bearing Florida account, in which case the landlord must pay the tenant either 75% of the annualized average interest rate or 5% simple interest per year, paid annually.
3. Florida surety bond for the total amount of deposits held, plus 5% interest paid annually.

Within 30 days of receiving the deposit, the landlord must disclose to the tenant in writing the holding method, the name and address of the depository institution (or surety company), and whether the tenant is entitled to interest. Failure to disclose forfeits the landlord's right to require advance notice of vacancy under § 83.575 but does not by itself forfeit the deposit. Disclosure failures are common in DIY landlord operations and are a low-friction tenant-side lever in any deposit dispute.

Why procedural strict construction matters

The Florida appellate courts have repeatedly held that the § 83.49(3)(b) 30-day claim-notice deadline is strictly construed. Equitable arguments — the landlord was traveling, the tenant's forwarding address was unclear, the certified-mail receipt got lost in transit — do not save a defective notice. The strict-construction rule makes the 30-day deadline the single most outcome-determinative procedural fact in a Florida deposit dispute, on par with the rent-escrow rule under § 83.60(2) in residential evictions.

For tenants, the strict-construction rule is the primary leverage point. A tenant who has documented the move-out date and waited the statutory windows can routinely recover the full deposit even where actual damage existed — the landlord's procedural default does the legal work. Combined with the prevailing-party fee-shifting provision under § 83.49(3)(c), a clean procedural record makes small-deposit disputes economically rational to litigate.

A worked example

A Tampa tenant vacates on day 0 with a $2,000 deposit on a one-year lease. The landlord intends to claim $1,200 for carpet replacement and unpaid rent but does not send the certified-mail claim notice until day 35 — five days past the F.S. § 83.49(3)(b) deadline. By operation of statute, the landlord forfeits the right to claim against the deposit. The tenant sends a certified-mail demand citing § 83.49(3)(b) on day 40; the landlord does not respond. On day 50, the tenant files a small-claims action in Hillsborough County Court for $2,000 plus attorney's fees and costs under § 83.49(3)(c). The county court rules for the tenant on summary judgment — the procedural default is established by the certified-mail records and the calendar — and awards the full $2,000 deposit plus $3,500 in attorney's fees and $185 in court costs. The landlord pays $5,685 on what should have been a routine $800-net deposit return ($2,000 less the $1,200 claim).

The strategic read on this account: the landlord's loss was procedural, not substantive. If the landlord had sent a proper certified-mail notice by day 30 with a specific reason for each item of damage, the $1,200 claim would have stood (assuming no timely tenant objection). The five-day procedural delay turned a routine deposit accounting into a $5,685 statutory penalty.

What the calculator does not do

This is a planning and verification tool. It does not:

• Replace litigation counsel. Florida deposit-recovery practice involves substantive judgment — how to plead the wrongful-withholding count, how to handle a counterclaim for damages exceeding the deposit, when to demand a jury trial, how to handle the landlord's habitability counter-defense. Consult a Florida-licensed attorney for the specific case.
• Compute interest on the deposit. F.S. § 83.49(1) requires the landlord to pay interest on interest-bearing-account deposits (75% of annualized rate or 5%) and on surety-bond deposits (5%), but the interest math is account-specific and depends on the disclosed holding method. The calculator surfaces the statutory interest rate as a constant; verify the carrier's interest accounting against the disclosure notice and the depository institution's statements.
• Address commercial deposits. Commercial leases fall under Part I of F.S. Chapter 83 and have materially different deposit-return rules — most commercial leases displace the statutory framework with lease-specific deposit provisions that are enforceable as written.
• Handle mobile-home park deposits. Mobile-home park tenancies are governed by F.S. Chapter 723 with their own deposit rules; § 83.49 does not apply.
• Project pre-lease application or hold-fee disputes. Pre-lease deposits received under a rental application or hold agreement that does not result in a fully-executed lease are governed by general contract and unjust-enrichment principles; the 30-day claim-notice deadline does not apply in the same way because there is no "vacancy."

How this page is maintained

The substantive statutory framework of F.S. § 83.49 has been stable for decades; the 15-day, 30-day, and 15-day windows are settled Florida law. Recent legislative activity has been procedural — certified-mail clarification, advance-notice-of-vacancy enforcement under § 83.575, fee-schedule housekeeping — but the core procedural ladder is unchanged. We monitor each Florida legislative session and any appellate opinion that materially shifts the procedural picture, and refresh this page within the quarter after any statutory change.
