9 Home Insurance Surprises Hitting South Carolina Homeowners in 2026

On February 1, the last-resort insurer for coastal wind and hail raised its rates 7.5% on houses and 25% on mobile homes.

No hurricane had to hit the coast first.

Insurers build these increases out of rate filings, reinsurance bills, and paperwork some homeowners never open.

These are the home insurance surprises South Carolinians are running into in 2026.

Note: This is general information, not insurance or financial advice. Rates, coverage terms, and program rules are subject to change, so check the specifics with your insurer or agent.

1. Your Named Storm Deductible

A home insurance deductible used to be a number you could say out loud, like $1,000.

Near the water, many policies use a percentage instead.

Nineteen coastal states and Washington, D.C., let insurers charge a special hurricane deductible, and it runs 1% to 15% of your dwelling coverage.

On a Mount Pleasant house insured for $400,000, a 2% deductible means the first $8,000 of storm damage comes out of your own pocket.

That’s $8,000, not $1,000.

The version most coastal policies use is the named storm deductible, and a hurricane never has to form.

A tropical storm counts, so long as the National Hurricane Center has given it a name.

Some states cap that deductible at once per hurricane season, and your policy is where you find out whether yours does.

By law, insurers have to explain the trigger using a $100,000 policy as the example, both when they write the policy and at every renewal.

So the answer sits in the packet you throw away.

2. Hail, Not Hurricanes

Ask around Spartanburg why home insurance keeps costing more, and somebody will blame the coast.

The bigger cost falls as hail on Upstate roofs, two hundred miles from the beach.

Severe convective storms, the industry’s term for thunderstorms that bring hail, straight-line wind, and tornadoes, have passed tropical cyclones as the costliest insured peril of this century.

Hail alone drives 50% to 80% of those losses, according to the same Insurify analysis.

Six states averaged a 20% home insurance rate increase in 2025: Minnesota, Iowa, Nebraska, Colorado, Oklahoma, and South Carolina.

Five of them are landlocked.

That 20% is a statewide average, so Upstate renewals sit inside it right alongside the beach houses.

3. Your Roof, Minus Depreciation

An insurer that once bought you a whole new roof may now pay you what your old roof is worth.

Many carriers do it with a roof payment schedule, setting a value by the roof’s age and material long before a storm shows up.

Picture a $20,000 roof at ten years old, depreciating $1,000 a year, on a policy with a $1,000 deductible.

Under actual cash value, $11,000 of that roof replacement is yours to cover.

With replacement cost, you pay the deductible and walk away.

Many schedules apply only to wind and hail losses, so a kitchen fire still gets you a whole new roof.

An insurer can also drop you over the roof’s age alone, and state law gives you 60 days’ notice and the precise reason in writing.

You never filed a claim.

4. Two Premiums, One House

One coastal house often carries two property policies, since insurers sell the wind and hail coverage on its own.

That second policy comes from the South Carolina Wind and Hail Underwriting Association, which everybody calls the wind pool.

Lawmakers made the insurance industry fund it back when coastal wind coverage started drying up.

Here’s the part that catches people: The wind pool writes a limited peril policy for wind and hail damage, so fire, theft, burst pipes, and liability all sit with a different company.

Coverage for a home tops out at $1.3 million across everything the policy covers, counting the structure, the contents, loss of use, and increased construction costs.

Every policy runs one year at a time.

Rates went up on February 1, 2026, by 7.5% on dwelling policies and 25% on mobile home policies.

That’s two premiums.

5. Insurance Without a Safety Net

When the standard home insurance market says no, your agent goes shopping in surplus lines.

Those companies price and word their policies without the state signing off first.

The bigger difference shows up as a stamped warning on the policy: This company carries no guaranty fund protection.

Translated, that means the South Carolina Property and Casualty Insurance Guaranty Association won’t pay your claim if the company fails, the way it would for a carrier the state licensed.

There’s no backstop.

Many homeowners read past the warning, since it looks like every other line of boilerplate on the page.

6. Almost Nobody Buys Flood

Roughly 8% of homeowners in the state carry a flood policy.

The rest are covering that risk out of their own savings, whether they picture it that way or not.

Charleston's flood-zone page puts about a quarter of all flood insurance claims in low-to-moderate risk areas.

That's outside the shaded zones.

Nobody in those areas had to buy anything, since no lender required it.

And a homeowners policy pays nothing toward flood damage, in this state or any other.

7. Your Flood Premium Escalator

Flood premiums on older policies rise by schedule, not by accident.

The Federal Emergency Management Agency calls it a glide path.

A policy written before 2021 rises as much as 18% to 25% a year until it reaches a full risk-based rate.

Even a policy already sitting at that full rate goes up as much as 18% a year for inflation.

There's no opting out.

The statewide average premium through the National Flood Insurance Program went from $695 in 2024 to $743 in 2025.

On Pawleys Island, the average already runs $4,199 a year.

8. Grant Money You Can't Get

The state helps pay to toughen roofs against the storms driving home insurance up, through a program called SC Safe Home.

It reopened to new applicants on February 10, 2026, with grants of up to $7,500 toward roof retrofits, up to $5,000 for smaller jobs, and up to $3,000 for hurricane shutters.

The portal has since closed.

Sign up for the email notice of the next opening, and confirm the window is open before you count on that money.

Not everyone can apply anyway.

You have to live in a designated coastal county, own and occupy the house as a single-family primary residence, carry active homeowners insurance, and have never taken a Safe Home grant before.

The Department of Insurance also turns away anyone whose property carries a previous storm-related damage claim.

So a Murrells Inlet family whose roof lost shingles in the last tropical storm is out.

Every homeowner in Greenville, Columbia, and Rock Hill is out too, since the Upstate and the Midlands sit outside the coastal counties entirely.

9. Your Unclaimed Tax Credit

Property insurance premiums above 5% of your adjusted gross income earn you a state income tax credit, and hardly anybody takes it.

Homeowners premiums, wind and hail premiums, and flood premiums all count toward that threshold on your legal residence.

At $65,000 of income, only the premiums above $3,250 count toward the credit.

The credit tops out at $1,250 a year, and anything you can't use carries forward five years.

It takes one form.

File form TC-44 with your state return, which is what 2,152 taxpayers did in 2021, for about $2.5 million between them.

It's nonrefundable, though, so a filer who owes no state income tax gets nothing back from it.
