Florida hurricane claim deadline: how long you have to file and the 18-month rule

Florida has cut its hurricane claim deadlines twice in the last five years. What used to be a three-year window is now one year, and most homeowners have no idea the law changed.

The deadlines matter more here than almost anywhere, because the damage that triggers the biggest claims in South Florida is frequently the damage nobody sees for months. Water that entered through a lifted shingle during a September storm does not announce itself. It shows up as a ceiling stain in February and as mold behind a wall in April, by which point the clock has been running for a long time.

Here is how the deadlines actually work, where the traps are, and what to do now if you took storm damage this season.

The deadlines, in short

The first three come from Florida Statute 627.70132. The last two come from 627.70131.

Everything below is the detail that decides whether those deadlines help you or bury you.

The one-year clock: when it starts and what counts as notice

The clock starts at the date of loss, not the date of discovery. For a hurricane, that is landfall. Not when your power came back, not when you first noticed the stain, not when your contractor finally returned your call. Damage you discover in month eleven faces the same deadline as damage you discovered the next morning.

This is the single most consequential feature of the statute and the one that catches people. There is no discovery rule written into it.

Notice means notice to your insurer, in the manner your policy requires. A call to your agent, a submission through the carrier's claim portal, or written notice to the claims department all generally qualify. What does not qualify: telling your contractor, telling your neighbor's adjuster, posting about it, or assuming the carrier knows because the whole street flooded. Notice has to reach the insurer, and you want proof of the date it did.

Missing it bars the claim. The statute's language is that an untimely claim "is barred." Not reduced, not disputed. Barred. A perfectly documented, clearly covered loss reported at thirteen months is generally worth nothing.

Older losses may run on the old rules. The current one-year and 18-month deadlines came from SB 2-A, effective December 16, 2022. Losses under policies whose period began before that date may still fall under the prior two-year and three-year deadlines. If you are dealing with something from Hurricane Ian or earlier, the older timeline may apply, and that is a question for an attorney rather than a blog post.

The deadline that is shorter than the deadline

Here is the part that surprises people, and it is the most useful thing in this article.

Meeting the statutory deadline does not mean you gave timely notice.

Your policy almost certainly contains its own notice provision requiring you to report a loss "promptly" or "immediately" or "as soon as practicable." That provision operates independently of the statute. Florida appellate courts have confirmed that reporting within the statutory window is necessary but not sufficient, and carriers have successfully denied claims filed inside the statutory deadline on the grounds that the insured breached the policy's prompt-notice requirement.

The practical translation: one year is the outer wall, not the target. A homeowner who notices roof damage in October and reports it the following August has met the statute and may still lose on prompt notice, because they cannot explain the ten-month gap.

Report when you become aware. Treat the statute as the thing that bars you absolutely, and the policy as the thing that can bar you earlier.

Supplemental and reopened claims: the 18-month window

These two terms get used interchangeably and they are not the same, and the difference is six months of deadline.

A supplemental claim is a claim for additional loss or damage from the same event, on a claim the insurer already adjusted, or for costs incurred while completing repairs under an open claim where timely notice was already given. You filed, they adjusted, work began, and the scope turned out to be larger than anyone knew. Deadline: 18 months from date of loss.

A reopened claim is an additional claim on a previously closed claim. Deadline: 1 year from date of loss, the same as an initial claim.

That distinction is the trap. Homeowners hear "18 months for later damage" and assume anything discovered after the initial adjustment gets eighteen months. It does not. Only supplemental claims do, and supplemental status generally depends on there being an open, timely-noticed claim behind it.

The practical consequence runs in one direction: file the initial claim early, even if the visible damage seems minor. A timely initial claim that stays open is what preserves access to the 18-month supplemental window. No initial claim means no supplemental claim, just a new claim subject to the one-year wall.

Why mold and hidden water damage surface after the first deadline

This is the part specific to South Florida, and it is why the deadlines bite harder here.

Storm damage to a building envelope is often small and invisible. A few lifted shingles, a compromised flashing detail, a hairline stucco crack, a window seal that failed under wind-driven rain. The storm passes, nothing is obviously wrong inside, and the homeowner concludes they got lucky.

Water that entered during those hours is now in the attic insulation, the wall cavity, or above the ceiling. In Broward County humidity it does not dry. Mold begins within 24 to 48 hours of the material getting wet, and then it grows quietly for months behind drywall. Our guide to the signs of hidden mold covers the signals that eventually appear.

The typical sequence looks like this. Storm in September. Nothing visible. A faint musty smell around December that gets attributed to the AC. A ceiling stain in February. A contractor opens the wall in April and finds the real extent of it.

That is seven months after landfall, and the homeowner never filed anything. They now have five months to report an initial claim on damage they will struggle to prove came from that storm, and they have no supplemental window at all because there was no initial claim.

The same homeowner who had filed a claim in October, even for a modest roof repair, would be in a completely different position.

The lesson is not to file frivolous claims. It is that visible minor storm damage is worth reporting, because the report is what preserves your position on the damage you have not found yet. Our emergency mold guide covers how fast the underlying problem develops, and the water damage cost guide covers what it costs when it is found late.

Flood policies run on a different, shorter timeline

If your damage came from flooding rather than wind, none of the above applies, because NFIP is federal and does not follow Florida's statute.

NFIP generally requires a signed, sworn Proof of Loss within 60 days of the loss. That is dramatically shorter than the state's one-year notice window, and it demands a detailed, documented, sworn statement of your claimed amounts rather than simply putting the carrier on notice. After large declared disasters FEMA frequently issues waivers extending this, but you cannot count on one.

Suit against NFIP must generally be filed within one year of the written denial, which is a separate clock from the state's.

The complication in a hurricane is that a single event often produces both wind damage and flood damage, governed by two policies with two different deadline structures and a frequent dispute about which peril caused what. If you have both, run both timelines in parallel from day one and assume the flood side is the urgent one.

Documentation to gather now, even if repairs are months away

Whatever your timeline, the file you build in the first weeks is what determines the outcome a year later.

Date-stamped photos and video of everything, interior and exterior, wide and close. Roof from the ground on all four sides, every room, every stain, every damaged item. Metadata matters, so use your phone rather than scanning prints.

Pre-storm photos if you have them. Anything showing the prior condition of your roof, ceilings, and exterior defeats the argument that the damage predated the storm. If you do not have them, take them now for next season.

The date and method of your notice to the carrier, plus the claim number and the adjuster's name and license number. Under 627.70131 the carrier must acknowledge within 7 calendar days and must identify the adjuster communicating about your claim.

Every communication in writing. If something important happens on a phone call, send a follow-up email summarizing it the same day.

All invoices and receipts, including emergency mitigation, tarping, drying equipment, and temporary repairs. Policies require you to mitigate, and they generally reimburse it when you document it.

Moisture readings and any inspection reports. A professional moisture assessment early establishes a baseline. If mold surfaces in month nine, a documented reading from month one is what connects it to the storm.

Contractor estimates and scopes of work, even for work you are not ready to start.

A written log of what you observed and when. A dated note saying you first noticed a musty smell in December is evidence; a recollection in April is not.

Frequently asked questions

How long do I have to file a hurricane claim in Florida? One year from the date of loss for an initial or reopened claim, and 18 months for a supplemental claim, under Florida Statute 627.70132. The clock runs from the date of the storm, not from when you discovered the damage.

What is the difference between a supplemental and a reopened claim? A supplemental claim seeks additional amounts on a claim the insurer already adjusted or that remains open, and it gets 18 months. A reopened claim is a new claim on a previously closed one, and it gets one year, the same as an initial claim. The distinction decides whether you have twelve months or eighteen.

What if I find mold or water damage a year after the storm? If you never filed, the initial claim window has likely closed and the claim may be barred. If you filed timely and the claim was adjusted or remains open, you may still be within the 18-month supplemental window. This is the situation where talking to an attorney or public adjuster is worth the call.

Does the deadline start when I discover the damage? No. It runs from the date of loss. Florida's statute contains no discovery rule for this purpose, which is why hidden damage is so often the damage that gets barred.

Can I lose a claim even if I file within one year? Yes. Your policy's own prompt-notice provision applies independently of the statute, and Florida courts have upheld denials where an insured filed within the statutory period but could not justify the delay. Report when you become aware.

Is the deadline different for flood damage? Yes, and it is shorter. NFIP generally requires a sworn Proof of Loss within 60 days of the loss, and suit must generally be filed within one year of a written denial. FEMA sometimes extends the Proof of Loss deadline after major disasters, but do not plan on it.

How fast does the insurer have to respond to me? Under Florida Statute 627.70131, the carrier must acknowledge your claim communication within 7 calendar days and must pay or deny the claim within 60 days of receiving notice, subject to limited tolling provisions.

Should I file a claim for minor storm damage? Discuss it with your agent, since claim history has its own consequences. But understand the trade-off: a timely initial claim is what preserves your access to the supplemental window if the damage turns out to be larger than it looked. The common and expensive mistake in South Florida is assuming minor visible damage means no hidden damage.

What to do this week

If you took any storm damage this season and have not reported it, the useful sequence is: photograph everything today, put your carrier on notice in writing, request the claim number and adjuster details, and get a professional moisture assessment if there is any chance water got into the structure. That last step is the one that connects a problem found later to the storm that caused it.
