Short-term rental insurance in South Carolina runs roughly $2,000–$14,000+ per year, with coastal properties paying several times more than Upstate listings. Three South Carolina-specific factors drive that spread: Atlantic hurricane wind and the South Carolina Wind and Hail Underwriting Association that often carries it, the higher rebuild cost of Charleston’s historic district properties, and the high-volume tourism density of Myrtle Beach and the Hilton Head resort market. Here are the real numbers.
The South Carolina-Specific Cost Drivers Other Guides Miss
Most STR cost guides quote one South Carolina number. That ignores how differently a Charleston historic single house, a Hilton Head villa, and a Greenville townhouse underwrite.
The first driver is coastal hurricane wind and SCWHUA. The South Carolina coast — from Myrtle Beach down through Charleston to Hilton Head — sits exposed to Atlantic hurricane wind, and standard carriers limit how much wind they will write near the shore. When they pull back, coastal wind and hail move to the South Carolina Wind and Hail Underwriting Association, the state’s residual market for the designated coastal area. A coastal STR’s program is often built with SCWHUA as the wind layer, carrying a named-storm deductible set as a percentage of dwelling value — real out-of-pocket exposure that doesn’t appear in the annual premium. The Insurance Information Institute’s hurricane facts document why coastal carriers price wind the way they do.
The second driver is Charleston’s historic district. Charleston’s Old and Historic District places properties under Board of Architectural Review oversight — and that is an insurance fact, not just a preservation one. A covered loss to a historic structure has to be repaired to preservation standards: historic-appropriate materials, period-correct methods, Board approval. That costs far more than standard reconstruction, which means a Charleston historic STR needs a dwelling limit set to true historic rebuild cost and Ordinance & Law coverage to absorb the upgrade gap. In our experience, the underinsured historic dwelling is the most expensive Charleston mistake.
The third driver is coastal tourism density. Myrtle Beach is one of the highest-volume tourism markets in the Southeast, and Hilton Head is a concentrated resort STR market — both with high occupancy, large guest capacity, and amenity-heavy properties that shape general liability cost. The South Carolina Department of Insurance regulates the carriers writing coverage across all of these markets.
Real Cost Ranges We See in South Carolina
In our experience placing South Carolina STR coverage, annual premium for a full program — general liability, dwelling, loss of rents, and contents — typically falls in these ranges:
- Upstate and inland urban STR (Greenville, Columbia): roughly $2,000–$4,500/year
- Charleston non-historic and near-coast STR: roughly $4,000–$8,000/year
- Charleston historic district STR: roughly $6,000–$12,000+/year, with full Ordinance & Law and historic rebuild limits
- Myrtle Beach and Hilton Head coastal STR: frequently $5,000–$14,000+/year, including coastal wind and a separate flood policy
- High-value oceanfront property: often $14,000+/year
These are program ranges, and on the coast the wind and flood layers can each cost as much as the rest of the policy combined. We don’t quote off a calculator — South Carolina placements run the property’s location, peril mix, construction era, and operating model through the specialty carrier panel.
Scenario: $1.1M Historic Single House in Downtown Charleston
We recently helped a host with a $1.1M historic single house in downtown Charleston — three stories, 4 bedrooms, inside the Old and Historic District and subject to Board of Architectural Review oversight. The property earns roughly $115K/year on Airbnb and VRBO. The owner had it insured on a policy written for a standard residence, with a replacement-cost figure that reflected ordinary construction — not the cost of rebuilding a protected historic structure.
That gap was the whole problem. A covered loss to a Charleston historic property has to be repaired to preservation standards: historic-appropriate materials, period-correct methods, and Board approval, all of which cost well beyond standard reconstruction. We rebuilt the program around a dwelling limit set to true historic rebuild cost, added Ordinance & Law coverage to absorb the code-and-preservation upgrade gap, and placed the wind layer with attention to the coastal deductible. Annual premium across the program came to roughly $8,900 — higher than the underinsured policy it replaced, but a limit that would actually rebuild the house. The lesson generalizes: in a historic district, the dwelling limit is the number that matters most.
Cost by Coverage Type in South Carolina
A South Carolina STR program is built from several coverage lines, and on the coast those lines may sit on more than one policy.
General Liability
General liability covers third-party bodily injury and property damage from guest stays — typically $1M each occurrence / $2M aggregate. Pools, hot tubs, beach access, and large guest capacity drive the rate. See general liability for short-term rentals.
Property / Dwelling
The dwelling line covers the structure. In a historic district, the dwelling limit must reflect historic rebuild cost, not ordinary construction. Inland it is a standard dwelling form. See property and dwelling coverage.
Wind — SCWHUA
In the designated coastal area, wind and hail frequently come from the South Carolina Wind and Hail Underwriting Association rather than the standard market. This is the line carrying the percentage named-storm deductible, and its cost is a major share of a coastal program.
Ordinance & Law
Ordinance & Law covers the gap between rebuilding what was there and rebuilding to current code — and, in Charleston, to preservation standards. On a historic property this line is essential, not optional. See Ordinance & Law coverage.
Flood
Flood is excluded from every property policy and written separately through the NFIP or a private market. Essential on the coast, where storm surge is a flood peril. See flood insurance.
Loss of Rents
Loss of rents replaces rental income while a covered loss makes the property unrentable. After a hurricane, coastal repair timelines run long — an extended period of restoration is worth pricing. See loss of rents coverage.
Umbrella / Excess
An umbrella stacks higher limits over primary GL — advisable for amenity-heavy coastal properties with large guest capacity, and usually one of the most cost-efficient lines. See umbrella and excess liability.
Cost by Major South Carolina Market
South Carolina STR pricing varies by market more than any single statewide number can show.
Charleston
Historic, high-demand coastal STR. Hurricane wind plus — in the Old and Historic District — preservation-standard rebuild cost. The dwelling limit and Ordinance & Law coverage deserve as much attention as the wind layer.
Myrtle Beach
High-volume tourism STR with hurricane wind and coastal flood exposure. Density and occupancy are high; pricing is moderate-to-high and the wind deductible is the line to confirm.
Hilton Head
Concentrated resort STR market — amenity-heavy villas and homes with hurricane wind and coastal flood. Among the higher-priced South Carolina markets.
Greenville Upstate
Inland Upstate STR — low catastrophe exposure, straightforward underwriting, prices toward the bottom of the range.
Columbia
Inland capital-city STR with steady business and event demand. Moderate pricing; no coastal wind layer.

The Most Common South Carolina STR Coverage Gap We See
South Carolina has two common coverage gaps, and which one applies depends on where the property sits.
On the coast, the gap is a beach or near-coast property insured like an inland home. A host carries over a standard homeowners policy with a flat dollar wind deductible, skips flood, and lists the property on Airbnb and VRBO. None of that holds up against a hurricane: standard carriers increasingly won’t write the wind, the flat deductible isn’t how coastal wind is structured, and flood — including storm surge — is excluded entirely. The mismatch surfaces the first time a storm comes through.
In Charleston’s historic district, the gap is quieter but just as costly: an underinsured dwelling limit. A historic single house insured at a replacement cost that reflects ordinary construction is underinsured for what it would actually take to rebuild it to preservation standards. After a fire or major loss, the owner discovers the limit won’t cover historic-appropriate reconstruction — and Ordinance & Law coverage, which would have absorbed the upgrade gap, was never on the policy.
Both gaps share a fix: a program built around the property’s real situation — coastal wind and flood placed deliberately, and a historic dwelling limit set to what preservation-standard rebuilding actually costs.
How to Lower Your South Carolina STR Insurance Costs
South Carolina premium responds to several levers — and on the coast, to a few that don’t exist Upstate:
- Choose the wind deductible deliberately. A higher percentage named-storm deductible lowers premium; size it to what you could absorb after a hurricane.
- Document wind mitigation. A newer roof, hurricane straps, and impact-rated openings can improve both pricing and insurability on coastal property.
- Get the historic rebuild limit right. In Charleston, an accurate historic replacement-cost figure avoids both underinsurance and overpaying — but never cut the limit to save premium.
- Bundle the program with one carrier. GL, dwelling, loss of rents, and contents written together usually price better than scattered placements, though SCWHUA wind and flood are separate by design.
- Keep flood in force. On the coast, the cheapest flood mistake is not having a policy at all.
- Don’t drop coverage to chase a lower premium. Skipping flood, thinning wind limits, or underinsuring a historic dwelling isn’t saving money — it relocates the loss to claim time.
When You Should Get South Carolina Quotes Restructured
Re-shop or restructure your South Carolina STR coverage when any of these is true:
- Your coastal property still carries a flat wind deductible from a pre-listing homeowners policy. Coastal wind is structured differently — and may need to move to SCWHUA.
- Your Charleston historic property’s dwelling limit reflects ordinary construction. That limit won’t rebuild a protected historic structure.
- You have no separate flood policy and the property is on or near the coast. That’s the gap to close first.
- You bought the policy before listing the property as an STR. A held-over homeowners policy doesn’t contemplate transient guests.
- You added a pool, hot tub, or guest capacity. The GL and umbrella exposure changed.
- It’s been more than a year since anyone reviewed the program. South Carolina coastal pricing and city ordinances both move.
If any of those apply, submit a quote and we’ll restructure the program around the property’s real South Carolina situation. The historic-rebuild challenge here parallels Savannah’s in our Georgia STR cost guide, and the coastal wind picture mirrors the Outer Banks in our North Carolina STR cost guide.
Frequently Asked Questions
How much does short-term rental insurance cost in South Carolina?
Most South Carolina STR properties run roughly $2,000–$14,000+ per year for a full program of general liability, dwelling, loss of rents, and contents. Upstate and inland listings in Greenville and Columbia sit at the low end; coastal properties in Charleston, Myrtle Beach, and Hilton Head sit at the high end because of hurricane wind and coastal flood. Charleston historic district properties carry an added cost layer — the higher rebuild expense of a protected historic structure.
Why is South Carolina coastal STR insurance so expensive?
The South Carolina coast carries Atlantic hurricane wind and coastal flood exposure that inland markets don't. Standard carriers limit how much wind they will write near the shore, so coastal wind and hail often move to the South Carolina Wind and Hail Underwriting Association, the state's residual coastal market, with named-storm deductibles set as a percentage of dwelling value. Flood is a separate policy on top. The peril stack — not the STR use by itself — is what lifts coastal premium.
What is SCWHUA and does my South Carolina STR need it?
The South Carolina Wind and Hail Underwriting Association (SCWHUA) is the state's residual market for windstorm and hail coverage in the designated coastal area, where standard carriers often won't write wind. If your STR is in that coastal tier, SCWHUA may be the wind layer underneath the rest of the program. An inland or Upstate South Carolina STR generally does not need it — wind and hail are covered on the standard property policy.
How does Charleston's historic district affect STR insurance?
Charleston's Old and Historic District places properties under Board of Architectural Review oversight, and that changes the insurance math. A covered loss to a historic structure must be repaired to preservation standards — historic-appropriate materials and methods — which costs far more than standard reconstruction. A Charleston historic STR needs a dwelling limit set to true historic rebuild cost and Ordinance & Law coverage to absorb the code-and-preservation upgrade gap.
What's the most common South Carolina STR coverage gap?
Two gaps are common. On the coast, it's a property insured on a standard homeowners policy with a flat wind deductible and no flood coverage — a structure that can't respond to a hurricane. In Charleston's historic district, it's an underinsured dwelling limit that reflects ordinary construction rather than the cost of rebuilding a protected historic structure to preservation standards. Both surface at claim time, and both are avoidable.
Are Airbnb's AirCover and VRBO's host protection enough for South Carolina properties?
No. Airbnb's AirCover and VRBO's host liability program are supplemental — they are not a substitute for a property's own insurance policy, and they exclude major South Carolina exposures including hurricane wind damage to the structure, flood, and loss of rents during a coastal evacuation. They also do not address SCWHUA wind placement or historic rebuild cost. A South Carolina STR needs a dedicated policy that responds where the platform programs end.
How fast can STR Guard quote South Carolina short-term rental insurance?
We typically return South Carolina STR quote requests within 1–2 hours during business hours. Coastal placements that require SCWHUA wind plus a separate flood policy, and Charleston historic placements where the rebuild limit needs to be set carefully, can take a little longer — but you will hear back the same business day. Submit the property details through the quote form and we structure a program from carriers actively writing South Carolina short-term rental coverage.
The Bottom Line on South Carolina STR Insurance Cost
South Carolina STR insurance cost is driven by geography and, in Charleston, by history. On the coast — Charleston, Myrtle Beach, Hilton Head — the program is an assembled one: SCWHUA wind, a separate flood policy, and a specialty STR dwelling form, with named-storm deductibles that carry real out-of-pocket exposure. In Charleston's historic district, the added factor is rebuild cost: a protected historic structure costs far more to restore to preservation standards, which means a higher dwelling limit and Ordinance & Law coverage. Upstate and inland, premium is moderate and underwriting is straightforward.
