Short answer: Many South Carolina coastal homeowners policies have a separate hurricane, named storm or wind and hail deductible, usually set as a percentage of the dwelling coverage limit, not of the damage. The SC Department of Insurance's example: a home insured for $250,000 with a 2% deductible means the owner pays the first $5,000. South Carolina doesn't cap the percentage, but Regulation 69-56 and SC Code 38-75-755 require insurers to disclose the deductible, show a $100,000 example and explain what triggers it.
Key facts
- How it's figured: a percentage of the insured value (the dwelling limit), not of the loss. Example: 2% of $250,000 = $5,000 (SC Department of Insurance, Post-Disaster Claims Guide).
- When it applies: only to losses from the event the policy names (a named storm, hurricane, or wind and hail); other damage uses the regular "all peril" deductible (SC DOI).
- Required warning: the policy face and declarations page must say the policy "contains a separate deductible for named storm or wind/hail losses, which may result in high out-of-pocket expenses" (Regulation 69-56).
- Required example: a $100,000 example showing how the deductible works and what triggers it (Regulation 69-56; SC Code 38-75-755).
- Renewal changes: adding a named storm deductible or raising its percentage at renewal needs the insured's signature or initials (Regulation 69-56).
- Maximum percentage: we found no SC rule capping it; it depends on the insurer and what you choose.
- Flood is separate: an NFIP policy has its own building and contents deductibles (FEMA).
- Tax help: SC allows a deduction for Catastrophe Savings Account deposits held for hurricane deductibles (SC Code 12-6-1620).
What is a hurricane or named storm deductible?
It's a separate, usually larger deductible that applies only when a specific kind of storm causes the damage. The SC Department of Insurance explains that some policies have a special deductible for wind, hurricanes or other storms, applied when one of those causes the damage; anything else uses the policy's regular deductible. The policy defines the trigger. Some use a "named storm" (one named by the National Hurricane Center), some a "hurricane," and some apply to any wind or hail loss.
A separate wind and hail policy from the SC wind pool also uses percentage deductibles, set out in its own manual.
How is a percentage deductible calculated?
Multiply the percentage by the dwelling coverage limit on the declarations page, not by the size of the claim. The Department of Insurance's worked example:
| Step | Flat $500 deductible | 2% deductible |
|---|---|---|
| Insured value (dwelling) | $250,000 | $250,000 |
| Deductible | $500 | $250,000 x 2% = $5,000 |
| Cost to rebuild after total loss | $250,000 | $250,000 |
| Claim payment | $249,500 | $245,000 |
Scale that to a Hilton Head house. On a dwelling limit of $800,000, a 2% deductible is $16,000 and a 5% deductible is $40,000. A small roof claim after a tropical storm might fall entirely under that amount. The percentage looks small on a quote; the dollars aren't.
What must a South Carolina insurer tell me?
More than many buyers realize, and it's worth reading. Under Regulation 69-56, an insurer can't issue or renew a policy with a named storm or wind and hail deductible unless:
- The policy includes an example, using a $100,000 home, showing how the deductible works and what event triggers it.
- The face of the policy and the declarations page carry the notice: "This policy contains a separate deductible for named storm or wind/hail losses, which may result in high out-of-pocket expenses to you."
- If the insurer adds a named storm deductible at renewal or raises the percentage, the named insured signs or initials an acknowledgment.
SC Code 38-75-755 adds a disclosure at every new policy and renewal: whether a separate hurricane, wind or named storm deductible applies, whether flood and mold are covered, that NFIP flood insurance is available, whether the policy pays replacement cost or actual cash value, and which windstorm mitigation discounts are available.
Is there a cap on hurricane deductibles in South Carolina?
Not that we could find. South Carolina regulates how the deductible is disclosed, not how high the percentage can go. Insurers offer a range, and a higher deductible lowers the premium. Pages that state a single "standard" South Carolina hurricane deductible are describing one insurer or one product, not a state rule. Choose the deductible based on the cash you could actually pay after a storm.
How do wind, flood and association deductibles stack up?
After a hurricane on Hilton Head, one event can hit several deductibles:
- Wind: the named storm or hurricane deductible on your homeowners policy, or on a separate wind pool policy.
- Flood: storm surge and rising water fall under the flood policy, which has its own deductibles for building and for contents.
- Owners association: for a villa or condo, the association's master policy may have its own wind deductible. Ask how the association would cover it (reserves or a special assessment) and whether your own policy has loss assessment coverage.
Ask for every deductible in dollars, side by side, before you choose a policy.
How can I lower the cost without a huge deductible?
Mitigation is the main lever. South Carolina requires coastal rating plans to include discounts or surcharges for storm shutters, roof tie-downs, construction standards and building codes, distance from water, elevation, flood insurance, policy deductibles and other factors (SC Code 38-73-1095(C)). A roof and opening upgrade can also qualify for an SC Safe Home grant when the program is open, and a state income tax credit of up to $1,000 for retrofits to your legal residence (SC Code 12-6-3660).
To set money aside for the deductible itself, SC Code 12-6-1620 allows a state income tax deduction for deposits to a Catastrophe Savings Account. The limit is $2,000 if your deductible is $1,000 or less; otherwise the lesser of $15,000 or twice the deductible.
How we help
We'll ask the seller for the current declarations page so you can see the existing wind deductible, and for villas, the association's master policy summary and deductible. Your agent can then quote a few deductible options on the actual house during your due diligence period.
Questions
Does a hurricane deductible apply to a tropical storm?
It depends on the policy's trigger. A "named storm" deductible usually applies to tropical storms as well as hurricanes, since both get names; a "hurricane" deductible may not. The required $100,000 example in your policy explains the trigger.
Is my flood deductible part of my hurricane deductible?
No. Flood is a separate policy with its own deductibles. If one storm causes both wind and flood damage, you may pay both deductibles.
Where do I find my hurricane deductible?
On the declarations page. South Carolina requires the separate deductible notice there and on the face of the policy, along with a $100,000 example. Convert any percentage to dollars using your dwelling limit.
