Florida Self-Storage Lien Sale Calculator

How this calculator works

Florida's self-service storage facility law (F.S. § 83.801-83.809, the Florida Self-Service Storage Facility Act) gives the operator a statutory lien on the contents of a rented unit for unpaid rent, late fees, and reasonable expenses of sale — and a procedural roadmap for enforcing that lien by public auction. The roadmap is not optional. A facility operator who shortcuts the notice clocks, skips newspaper publication, sells before the cure window has run, or fails to remit surplus proceeds to the tenant exposes itself to wrongful-sale liability under F.S. § 83.808 (conversion damages, the tenant's attorney fees, and in egregious cases punitive damages).

The calculator projects the lien-enforcement arc end-to-end from any procedural stage. The five headline outputs:

1. Total amount owed. Principal rent (monthly × months delinquent) plus accrued late fees plus reasonable sale and collection costs. This is the figure the default notice must state under F.S. § 83.806(2) and the floor the auction must clear before any surplus accrues to the tenant.
2. Current procedural step. Where the unit sits on the F.S. § 83.806 ladder — current, past due with late charges accruing, default-but-no-notice, default-notice-with-cure-window-running, cure-window-expired, sale-notice-published-with-15-day-window-running, or sale-ready.
3. Sale-readiness verdict. Concrete narrative describing whether the operator is procedurally clear to hold the auction, including remaining days on whichever statutory clock is running.
4. Expected surplus to tenant. What the tenant receives under F.S. § 83.806(4) if the auction clears at the expected hammer price. Surplus is held in trust for the tenant for 6 months from the sale date; unclaimed surplus escheats to the operator at the end of the window.
5. Procedural-compliance verdict. Flags any procedural defect that would expose the operator to F.S. § 83.808 wrongful-sale liability — premature default notice (before the 10-day trigger), premature sale notice (before the cure window expires), or sale notice published without any default notice ever sent.

The F.S. § 83.806 procedural ladder

Every Florida self-storage lien sale runs through a strict procedural sequence. Each step has a statutory clock; skipping any step or shortcutting any clock voids the sale.

• Default and late charge (F.S. § 83.806(1)). Rent is past due on the due date stated in the rental agreement. Late charges typically begin around day 5; the statute does not cap the amount but most facility rental agreements set $20-$50 per month. Late charges accrue for each delinquent month.
• 10-day default trigger (F.S. § 83.806(2)). When the tenant has been in default at least 10 days, the operator may send a written default notice to the tenant's last-known address (and to any designated alternative-contact address). Certified mail is the operator's preferred service method because it produces a delivery record for the procedural file. Email and posted-notice service are also permitted under the modern statute, but certified mail remains the gold-standard practice. The default notice must state the amount owed and provide a reasonable opportunity to cure — the statute does not specify a day count, but most rental agreements provide 15 to 30 days. The calculator uses 15 days as the lower-bound cure-window default.
• 15-day public sale notice (F.S. § 83.806(3)). No earlier than the expiration of the cure window, the operator must (a) publish the public sale notice in a newspaper of general circulation in the county where the facility sits, once a week for two consecutive weeks, AND (b) post a copy of the notice on the premises in a conspicuous location near the unit. The auction may be held no earlier than 15 days after the first newspaper publication. The two-week newspaper requirement is the single most-missed procedural step by DIY operators — many facilities try to substitute online-only posting, which is not sufficient under the current statute.
• Public auction. The operator conducts a public auction of the unit contents at the facility, typically run by a licensed auctioneer or through a self-storage-auction service (StorageTreasures, Lockerfox, BidOnStorage). Cash sales; same-day removal usually required. The tenant retains the F.S. § 83.806(5) right of redemption — meaning the tenant may cure by paying the amount owed at any point before the hammer falls.
• Proceeds distribution (F.S. § 83.806(4)). From the auction proceeds, the operator deducts in order: (a) rent owed, (b) late fees and other charges authorized by the rental agreement, and (c) the reasonable expenses of the sale (newspaper publication, auctioneer fee, postage, labor for unit cleanout). Any surplus is held in trust for the tenant for 6 months from the sale date. The operator should notify the tenant in writing at the last-known address that surplus is available and how to claim it; a check sent to the last-known address is the common practice. Unclaimed surplus at the end of the 6-month window escheats to the operator under § 83.806(4).

The tenant's right of redemption — F.S. § 83.806(5)

The single most important tenant protection in the Florida Self-Service Storage Facility Act is the right of redemption under F.S. § 83.806(5). The tenant may cure by paying the amount owed (rent plus late fees plus reasonable sale costs accrued to that point) at any time before the sale is final — meaning up to and including the moment the hammer falls at the auction.

Most facility operators set a written cutoff in the rental agreement or in the default notice (e.g., "redemption must be paid by 5pm the day before the auction in cleared funds") to avoid auction-day disputes. The statute itself runs the redemption right through the hammer, but a contractual cutoff in the rental agreement is generally enforceable and helps administer the auction.

After the hammer falls, the buyer takes title to the unit contents and the tenant's redemption right is extinguished. Buyers at self-storage auctions typically have a same-day removal requirement — the unit must be emptied within 24-48 hours of the sale, which forecloses any practical post-sale redemption opportunity even if the operator wanted to grant one.

What F.S. § 83.808 makes the operator liable for

F.S. § 83.808 imposes liability on the operator for wrongful sale. The tenant's claims typically include:

• Conversion damages. The fair market value of the unit contents at the time of sale — which can run far above the auction hammer price for items with sentimental, business, or collector value. A unit of $50,000 in business equipment that sold at auction for $800 produces $49,200 in conversion exposure if the sale was wrongful.
• Breach of the implied covenant of good faith in the rental agreement.
• The tenant's attorney's fees in a contractual or statutory fee-shifting posture. Most Florida self-storage rental agreements contain mutual fee-shifting clauses; the tenant invokes them on a wrongful-sale claim.
• Punitive damages in egregious cases where the operator's conduct was willful or reckless.

The procedural defects that most commonly trigger F.S. § 83.808 liability:

• Default notice sent before the 10-day trigger.
• Public sale notice published before the cure window expired.
• Failure to publish in a newspaper of general circulation (online-only posting is not sufficient).
• Failure to publish for two consecutive weeks.
• Failure to post the sale notice on the premises.
• Failure to hold surplus in trust for the 6-month claim window.
• Auction held before the 15-day window has run from the first newspaper publication.

The cost of strict procedural compliance is trivial — newspaper publication for two consecutive weeks runs $75 to $150 in most Florida counties, certified mail for the default notice runs about $8, and the surplus-trust accounting is a basic ledger entry. The cost of a F.S. § 83.808 judgment can run into five and six figures. Defend the procedural file at every step.

A worked example

A Tampa self-storage facility has a 10-by-15 unit rented at $150 per month to a tenant who stopped paying after six months in the unit. The tenant is now three months past due.

• Total owed at the point the default notice goes out: $450 in principal rent (3 × $150) + $75 in accrued late fees (3 × $25) + $200 in sale costs allocated to the file = $725.
• The operator sends the F.S. § 83.806(2) default notice on day 31 of default by certified mail to the tenant's last-known address. The notice states the $725 owed and provides 15 days to cure.
• Day 46: the cure window expires without cure. The operator orders newspaper publication of the public sale notice in the Tampa Bay Times for two consecutive weeks (cost: $135). The notice is also posted on the unit door (photograph for the procedural file).
• Day 61 (15 days after the first publication): the auction is held. A self-storage-auction service runs the sale. The unit contents (mostly furniture, kitchen items, a few boxes of clothes) hammer at $500.
• Proceeds distribution under F.S. § 83.806(4): $500 hammer minus $450 principal minus $75 late fees minus $200 in sale costs = negative $225. The auction did not cover the amount owed. The operator absorbs the deficiency; no deficiency judgment is available against the tenant under the Self-Service Storage Facility Act.
• No surplus. The 6-month trust window does not apply.

The strategic read: most Florida self-storage auctions clear at 30 to 60 percent of estimated unit content value, which is typically far below the rent-plus-late-fees-plus-costs total once a unit is more than 4 to 6 months delinquent. The operator's procedural energy should focus on cycling units through to auction as quickly as the F.S. § 83.806 clocks allow — every additional month past due is a month of rent the auction probably will not recoup.

A different worked example with a surplus: a $300/month climate-controlled unit, 4 months delinquent ($1,200 rent + $100 late fees + $200 costs = $1,500 owed), where the contents include a vintage motorcycle that hammers at $4,200. Proceeds distribution: $4,200 - $1,500 = $2,700 surplus held in trust for the tenant for 6 months. The operator sends a check for $2,700 to the tenant's last-known address. If the check goes uncashed and no claim is made within 6 months, the surplus escheats to the operator under F.S. § 83.806(4). If the tenant surfaces within the 6-month window and cashes the check (or claims a replacement), the surplus is theirs.

What the calculator does not do

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

• Replace litigation counsel. F.S. § 83.806 procedural questions — when has a "reasonable opportunity to cure" been provided; what counts as a "newspaper of general circulation"; how should the operator handle a tenant who claims they never received the default notice — involve substantive judgment. Consult a Florida-licensed attorney for the specific facility's practice.
• Handle titled-property auctions. Motor vehicles, watercraft, and manufactured homes follow a separate procedural track under F.S. § 83.807, which incorporates DMV / FWC title-transfer and notice requirements specific to each property type. Selling a titled vehicle under the wrong statutory track produces a buyer who cannot get clean title and a wrongful-sale claim from the tenant. If a unit contains titled property, segregate the titled items, follow § 83.807 for them, and use the standard § 83.806 procedure only for the non-titled remainder.
• Compute exact day-of-week or holiday exclusions. The F.S. § 83.806 clocks run as calendar-day windows; the statute does not exclude weekends or holidays from the 10-day default trigger or the 15-day sale-notice window. The cure window's day count is contractual (per the rental agreement). Confirm the rental agreement's specific cure-period language before relying on the 15-day calculator default.
• Address commercial-lease subtenancy or pre-existing security interests. A self-storage unit holding inventory subject to a UCC-1 security interest, or items held under a separate commercial-lease arrangement, may produce competing-claim disputes between the storage operator's statutory lien and the prior secured creditor. The Self-Service Storage Facility Act's lien is generally senior to subsequent perfected interests, but the priority analysis for a pre-existing UCC-1 is fact-specific. Consult counsel before auctioning a unit with known third-party interests.
• Project precise auction proceeds. The expected-proceeds input is an operator estimate; actual hammer prices vary widely based on unit contents, market conditions, and auction-service quality. High-density South Florida storage markets (Miami-Dade, Broward, Palm Beach, Orange County) tend to outperform on auction yields; rural markets underperform.

How this page is maintained

The substantive framework of the Florida Self-Service Storage Facility Act has been stable since the modern revision in the early 2010s; the 10-day default trigger, the cure-window requirement, the 15-day public sale notice with two-week newspaper publication, and the 6-month surplus trust window are settled Florida law. Recent legislative activity has been incremental — clarifying email-service permissions for the default notice, updating language for online-auction permissibility — but the core procedural sequence 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.
