If a storm has damaged your home in New York or Connecticut and your insurer is applying a “hurricane deductible” or “windstorm deductible” that is far larger than the flat dollar amount you expected, you are not being overcharged by mistake. Many homeowners policies in these two states use a percentage-based deductible for hurricane or windstorm losses instead of, or in addition to, a standard flat-dollar deductible. Here is how these deductibles actually work and how to check whether yours is being applied correctly.
How a percentage deductible works
Instead of a flat amount like $1,000, a percentage deductible is calculated as a percentage, commonly 1 percent to 5 percent, of your dwelling’s insured value (Coverage A) or, in some policies, the total insured value. For example, on a home insured for $400,000 with a 2 percent hurricane deductible, you would be responsible for the first $8,000 of a covered hurricane loss before your insurer pays anything, a much larger out-of-pocket amount than a standard $1,000 or $2,500 deductible.
New York’s rules on hurricane and windstorm deductibles
According to the New York Department of Financial Services (DFS), windstorm and hurricane deductibles commonly range from 1 percent to 5 percent of the dwelling’s insured value, and insurers are required to disclose the calculated dollar amount on the declarations page, as explained in the DFS Homeowners Insurance: Basic Coverage guide. This disclosure requirement stems from Insurance Regulation 159 (11 NYCRR Part 74).
New York has also recently finalized a Third Amendment to Regulation 159, creating a uniform statewide definition of “hurricane” and standardizing how these deductibles operate. Under the updated regulation, effective February 2, 2026, according to reporting from the Professional Insurance Agents of New York and a legal summary from Chartwell Law:
- A “hurricane” is defined uniformly as a tropical cyclone with sustained surface winds of 74 miles per hour or higher, as determined by the National Weather Service.
- The hurricane deductible can only be triggered after the storm makes landfall in New York State.
- It applies only to wind damage occurring in a defined 24-hour window: beginning 12 hours before landfall and ending 12 hours after the last hurricane watch or warning for New York is canceled.
- The deductible must be displayed clearly, both as a percentage and as a calculated dollar amount, along with a plain-language disclosure notice.
- It cannot be applied to loss-of-use (additional living expense) coverage.
- Only one deductible, generally the higher of multiple applicable deductibles, applies to a single covered loss.
Connecticut’s rules on hurricane deductibles
Connecticut law, at Conn. Gen. Stat. Section 38a-316a, allows insurers to apply a separate hurricane deductible in place of the standard policy deductible, but only during a specific triggering window and only for wind-related damage from a declared hurricane. According to the Connecticut Insurance Department’s consumer guidance:
- A hurricane deductible may only apply when a hurricane, defined as sustained surface winds of 74 miles per hour or greater, is declared by the National Hurricane Center for any part of Connecticut.
- The deductible period begins when the hurricane warning is issued and ends 24 hours after the warning is terminated or the storm is downgraded from hurricane status, whichever comes first.
- Ordinary windstorm or wind/hail deductibles, separate from hurricane-specific deductibles, cannot be mandated by insurers in Connecticut; they are optional and chosen by the policyholder, often in exchange for a premium discount.
- Connecticut Insurance Department coastal underwriting guidelines generally cap hurricane deductibles at 5 percent for properties within 2,600 feet of the coast and 2 percent beyond that distance, according to the department’s coastal underwriting guidelines.
What to check on your own policy
- Look at your declarations page for a separate line labeled “hurricane deductible” or “named storm deductible,” distinct from your standard “all other perils” deductible.
- Confirm the percentage shown and calculate the actual dollar amount against your Coverage A limit.
- If your insurer applied a hurricane deductible to your claim, confirm that the storm was actually declared a hurricane, with sustained winds of 74 mph or more, by the National Weather Service or National Hurricane Center, and that your loss occurred within the defined trigger window. If the storm was a tropical storm or a non-hurricane wind event, a general hurricane deductible should not apply.
- Ask your insurer to show its calculation in writing if you believe the deductible was applied incorrectly.
Frequently asked questions
Is a hurricane deductible the same as a windstorm deductible?
Not necessarily. A windstorm or wind/hail deductible can apply more broadly to any wind event, while a hurricane deductible is specifically tied to a storm that has been declared a hurricane, with the timing and wind speed requirements described above. Check your policy to see which type, or types, you carry.
What if my storm was only a tropical storm, not a hurricane?
If the storm never reached hurricane status (sustained winds of 74 mph or more) as determined by the National Weather Service, a hurricane-specific deductible generally should not apply, and your standard deductible should govern instead, though you should confirm this against your specific policy definitions.
Can my insurer apply both a hurricane deductible and my regular deductible to the same loss?
No. Under New York’s updated Regulation 159 and Connecticut’s guidelines, only one deductible, typically the higher one, should apply to losses caused by a single storm event, even if multiple deductible provisions could theoretically apply.
