There is a number printed on the front page of your homeowners policy next to the word "deductible." For most households it is $1,000. In 19 states and the District of Columbia, it is very likely not the number that will apply to the claim you are most likely to file.
Storm damage in those states runs through a second, separate deductible, expressed as a percentage of your dwelling coverage rather than as a flat dollar figure. On $400,000 of coverage, a 2% hurricane deductible is $8,000. The $1,000 on the front page applies to a kitchen fire, a burst pipe, and a theft. It does not apply to the hurricane.
That gap — between the deductible people think they have and the one that governs their largest realistic loss — is the single most consequential thing about a coastal homeowners policy, and it is disclosed in a place nobody reads.
A note before you start. This is general education, not insurance advice. State counts and trigger definitions come from NAIC and from the cited state statutes and regulations, each with its own date, because these change: NAIC restates the deductible count periodically and New York's rules changed in February 2026. Percentage and premium figures described as averages are computed from this site's own sourced 50-state dataset. Your own trigger, percentage, and coverage limit are on your declarations page, and they are what govern — NAIC's own caveat is that "no two laws are identical; triggers vary from state to state, as well as from insurer to insurer."
1. Where these deductibles apply
NAIC's hurricane deductibles page, updated 2 June 2025, states that "nineteen states and the District of Columbia have some form of hurricane or named storm deductible in place." Those states are:
Alabama · Connecticut · Delaware · Florida · Georgia · Hawaii · Louisiana · Maine · Maryland · Massachusetts · Mississippi · New Jersey · New York · North Carolina · Pennsylvania · Rhode Island · South Carolina · Texas · Virginia, plus the District of Columbia.
Two things about that list surprise people. Pennsylvania is on it. Maine is on it. These are not the states anyone pictures when they hear "hurricane deductible," and their presence is a reminder that the trigger is a policy provision rather than a geographic fact.
An older figure of "18 states" still circulates — it omits Pennsylvania and does not count DC. Use the dated NAIC statement rather than an undated summary, and carry the date with it, because this count changes.
Separately, and more broadly: across this site's own sourced 50-state insurance dataset, 36 states carry some catastrophe deductible convention, with a median of 2% of dwelling coverage. That larger number includes windstorm and wind/hail deductibles that are not tied to a named storm at all — which is the distinction the next section is about.
2. Three different triggers, commonly confused
The terms are not interchangeable, and which one your policy uses determines how often you meet it.
Hurricane deductible. NAIC: "typically applies to damage solely from a hurricane as categorized by the National Weather Service or U.S. National Hurricane Center." The narrowest trigger — it takes an actual hurricane.
Named storm deductible. Applies to an event "declared such as a typhoon, tropical storm or a tropical cyclone" by NWS or NHC. Broader: a tropical storm that never reaches hurricane strength still triggers it.
Windstorm or wind/hail deductible. Applies to any wind or hail damage, with no naming requirement at all. This is the one that catches the most claims, and it operates far inland. Texas is the standard example.
That third category is why a homeowner in Oklahoma or Ohio can have a percentage deductible without living anywhere near a coast. Severe convective storms — the ordinary summer hail and straight-line wind that damages roofs across the middle of the country — trigger a wind/hail deductible every season. A hurricane deductible might never be triggered in a lifetime of ownership; a wind/hail deductible is met routinely.
If you take one thing from this article, make it this: find out which of the three your policy uses. They are printed differently on every declarations page and they are not the same product.
3. What the percentage actually costs
The arithmetic is simple and the result is not intuitive, because people anchor on the flat deductible they are used to.
Percentage deductible = your Coverage A dwelling limit × the percentage.
Note what it is not a percentage of: not the claim, not the damage, not your home's market value. It is a share of the dwelling limit, so it is the same dollar figure whether the storm did $12,000 of damage or $300,000.
| Dwelling limit | 1% | 2% | 5% | 10% |
|---|---|---|---|---|
| $250,000 | $2,500 | $5,000 | $12,500 | $25,000 |
| $400,000 | $4,000 | $8,000 | $20,000 | $40,000 |
| $600,000 | $6,000 | $12,000 | $30,000 | $60,000 |
| $850,000 | $8,500 | $17,000 | $42,500 | $85,000 |
Set that against a $1,000 flat deductible and the multiples are stark. At $400,000 of coverage:
- A 1% deductible is 4× the flat figure
- A 2% deductible is 8×
- A 5% deductible is 20×
Now put it against a realistic loss. Hail takes your roof; the replacement is $22,000. Under a $1,000 all-perils deductible you are out $1,000. Under a 2% wind/hail deductible on $400,000 of coverage you are out $8,000 — and if the roof replacement had come to $7,500, you would be out the entire amount with no claim payment at all, because the loss did not exceed the deductible.
That last case is the one worth internalising. A high percentage deductible does not just make claims more expensive; it makes a whole band of real damage effectively uninsured, because filing produces nothing.
Work out what your own storm deductible comes to4. The trigger window: when it starts and stops
A hurricane deductible is not simply "applies during hurricanes." Every policy defines a window, and the window is where states have legislated hardest.
Florida sets it by statute. Fla. Stat. § 627.4025 defines a hurricane as one declared by the National Hurricane Center, and runs hurricane coverage from the issuance of a hurricane warning for any part of Florida through 72 hours after the last watch or warning terminates. Note the breadth: a warning anywhere in the state opens the window for everyone in it.
New York changed on 2 February 2026, and this is the most important currency note in this article. The third amendment to Regulation 159 (11 NYCRR Part 74), under Insurance Law § 3445, created statewide uniformity where carriers previously set their own windows. The trigger is now landfall in New York only, and the window runs 12 hours before landfall to 12 hours after the last watch or warning is cancelled (NY DFS).
Two details in that rulemaking matter. DFS expressly rejected the industry's request for a 24-hour window, and it rejected a watch/warning trigger in favour of actual landfall in the state. Section 74.4(a) also permits insurers to use a hurricane deductible only where they can demonstrate genuine hurricane exposure. Anything you read about New York hurricane deductibles written before 2026 describes a system that no longer exists.
South Carolina regulates the definition and, unusually, the disclosure. Regulation 69-56 (DOI Bulletin 2000-09) requires that a named storm be named by NWS or NHC and limits the trigger to a hurricane, tropical storm, or tropical depression — so a winter storm given a name by a television network cannot trigger it. It also requires the insurer to provide a worked example on a $100,000 loss, to print the all-caps warning "THIS POLICY CONTAINS A SEPARATE DEDUCTIBLE FOR NAMED STORM OR WIND/HAIL LOSSES, WHICH MAY RESULT IN HIGH OUT-OF-POCKET EXPENSES TO YOU," and to obtain a signed acknowledgment (SC DOI).
South Carolina's approach is the most honest in the country, and its existence tells you something: a regulator concluded that homeowners were not understanding this provision from the policy language alone, and required a worked example and a signature to fix it.
5. What the gap looks like across the states that have them
Take this site's own sourced dataset for the 17 hurricane-deductible states where a catastrophe deductible convention is recorded, and one pattern stands out that is not obvious from any individual policy.
Sixteen of them pair a 2% catastrophe deductible with a $1,000 typical all-perils deductible — a 6× multiple at the $300,000 reference coverage level the dataset uses. Florida is the exception: its typical all-perils deductible is $2,500, not $1,000, so the multiple there is 2×.
That is worth sitting with, because it runs against intuition. Florida has by far the highest average premium in the country — $8,471 a year against a national average of $2,724, and against Hawaii's $1,125 in the same hurricane-deductible group. Yet the jump between a Florida homeowner's ordinary deductible and their storm deductible is the smallest of the group, because the ordinary deductible already starts high.
Elsewhere the shock is larger even though the absolute numbers are smaller. A Connecticut homeowner paying $2,050 a year has been living with a $1,000 deductible and has a $6,000 one waiting. A Delaware homeowner paying $1,385 — one of the cheapest premiums in the group — faces the same $6,000.
| Typical all-perils | 2% catastrophe deductible | Multiple | |
|---|---|---|---|
| Florida | $2,500 | $6,000 | 2× |
| Every other state in the group | $1,000 | $6,000 | 6× |
Two conclusions follow.
A low premium is not evidence of a low deductible. Delaware and Hawaii sit near the bottom of this group on premium and carry the same percentage deductible as Louisiana and Alabama near the top. The premium reflects expected loss frequency and severity; the deductible reflects how much of the first-dollar risk the market has pushed back to you. They are different things and they do not move together.
The states where people are least prepared are not the coastal ones. In Florida and Louisiana, storm deductibles are a subject of ordinary conversation. In Connecticut, Rhode Island, Massachusetts, Delaware, Maryland, and Pennsylvania — all on NAIC's list — a homeowner may go decades without the trigger being met, which is exactly the condition under which nobody checks the number.
6. If you could not produce the deductible
This is the part of the conversation that gets skipped, because it is uncomfortable and because it does not have a product attached to it.
A percentage deductible you cannot pay does not reduce your coverage on paper. It reduces it in practice, completely, for any loss up to the deductible amount and severely for losses just above it — because the settlement arrives only after you have committed to the repair, and the first tranche of a replacement-cost claim is smaller than the settlement anyway.
Three things to do about it, roughly in order of how much they help.
Fund it deliberately, as a line item. Not "we have savings" — a specific amount, equal to the deductible, that is not earmarked for anything else. If your storm deductible is $8,000, that is the target, and reaching it changes the policy from theoretically adequate to actually usable.
Ask what a lower percentage costs before you assume you cannot afford it. The premium difference between 2% and 1% is a real number your agent can quote in a few minutes. On a household that has no realistic path to $8,000 in reserve, paying a few hundred dollars a year to halve the exposure is not obviously a bad trade — and it is a trade nobody offers you unprompted.
Know the sequence for the claim you can afford. Insurers commonly pay actual cash value first and release the balance after the work is done and documented. That means even a well-funded household fronts money. Knowing which contractor will start on a signed claim assignment, and what your carrier's timeline for the second payment is, is preparation that costs nothing and matters enormously in the week after a storm.
7. Annual, per-event, or per-season
One further variable that materially changes your exposure in a bad year.
Most percentage deductibles apply per event. Two hurricanes in one season means two deductibles. A household with a 2% deductible on $400,000 that is hit twice pays $8,000 twice.
Some states or policies apply the deductible on an annual basis instead — you meet it once in a calendar year and subsequent storms run through the ordinary all-perils deductible. Louisiana's statute is commonly cited as applying named-storm deductibles annually rather than per event; confirm the current text of La. R.S. 22:1337 at your state legislature's own site before relying on it, as this is exactly the kind of provision that gets amended.
It is a direct question worth asking your agent: "Is my hurricane deductible per event or per season?" In an active season the difference is tens of thousands of dollars.
8. Why carriers use them, and why you might choose one
It is worth understanding the mechanism rather than treating this as something done to you.
Hurricane losses are correlated. An ordinary house fire is an isolated event; one storm damages tens of thousands of homes in the same week, and the insurer must pay all of them at once from the same capital. Percentage deductibles shift a defined share of that correlated exposure back to policyholders, which is what makes coastal coverage writable at all in some markets.
The trade is real in both directions. A higher percentage deductible buys a lower premium — sometimes a substantially lower one — and for a household with genuine reserves and a newer, better-built roof, taking more of the first-dollar risk can be entirely rational.
What makes it a problem is when nobody chose it. These deductibles are frequently inherited from whatever the quote defaulted to, in a state where every carrier defaults similarly, and the first time the household engages with the number is after a storm.
Two questions turn it into a decision rather than a default:
- Could you produce the deductible in cash, this week, if you had to? Not over six months, not on a credit card — this week, alongside a deposit on temporary housing. If the answer is no, the percentage is too high regardless of what it saves in premium.
- What does each step down cost? Ask for the premium at 2%, at 1%, and at a flat figure if one is available. That converts an abstraction into a price you can weigh.
9. What to do about it, in order
Find all your deductibles. There will be at least two on a coastal policy and possibly three: an all-perils flat deductible, and one or more percentage deductibles for hurricane, named storm, or wind/hail. They are usually on the declarations page in a block, sometimes several lines apart.
Convert the percentage to dollars and write it down. Coverage A × the percentage. This is the number to plan around, not the flat one.
Establish which trigger you have. Hurricane, named storm, or wind/hail — they are met at very different frequencies, and wind/hail is the one you are most likely to actually meet.
Find out if it is per event or annual. One question, potentially five figures of difference in a bad season.
Check it against your emergency fund, honestly. A deductible you cannot produce turns a covered loss into an uncovered one.
Ask what a lower percentage costs. Then decide. The point is not that lower is better — it is that this should be a decision you made rather than one the quote made for you.
Frequently asked questions
Is my hurricane deductible a percentage of the damage? No — of your dwelling coverage limit. That is why it is the same dollar figure whether the storm did $12,000 or $300,000 of damage, and why it can exceed a modest loss entirely.
Do I have one of these? If you are in one of the 19 states or DC, quite possibly. But the broader category matters more: 36 states in this site's dataset carry some catastrophe deductible convention, including wind/hail deductibles far inland. Check the declarations page rather than reasoning from geography.
What is the difference between hurricane and named storm? A hurricane deductible generally requires an actual hurricane as categorised by the National Hurricane Center. A named storm deductible also triggers on a tropical storm or tropical depression that has been named. Named storm is the broader trigger, so it applies more often.
Why do people in Texas and Oklahoma have percentage deductibles? Because a windstorm or wind/hail deductible needs no named storm at all — any wind or hail damage triggers it. Severe convective storms drive most roof claims across the middle of the country, and that is the deductible those claims run through.
If two hurricanes hit in one season, do I pay twice? Usually yes — most percentage deductibles apply per event. Some states or policies apply them annually instead. It is worth confirming with your agent, because in an active season it is the difference between one deductible and several.
Can I get rid of it? Rarely, in the states where it is standard. What you can often do is choose the percentage — and the premium difference between 1% and 5% is real. Ask for quotes at each level rather than accepting the default.
My roof needs $7,000 of repair and my deductible is $8,000. What happens? Nothing is paid, and filing a claim that produces no payment can still appear in your claims history. This is the band of loss a high percentage deductible makes effectively uninsured, and it is a reason to know your number before deciding whether to file.
Does the deductible come out of my payment or do I pay it separately? It is subtracted from the settlement. On a $60,000 loss with an $8,000 deductible you receive $52,000 and fund the first $8,000 of the work yourself — which is why the cash-availability question matters more than the arithmetic.
What to do next
Convert your own percentage into dollars first — it takes one input. The deductible comparison calculator does that, shows what the storm deductible costs against the ordinary all-perils figure, and separately prices whether raising your regular deductible is worth the exposure, using your own two quotes rather than an invented savings percentage.
- Replacement cost calculator — your dwelling limit drives the percentage, so it is worth checking it is right
- Coverage check — all six limits against what a standard policy carries
- What homeowners insurance doesn't cover — including why flood sits outside all of this
- Replacement cost vs. actual cash value — the other provision that decides what a storm claim pays
