Commercial property insurance cost in coastal Georgia and South Carolina (2026)
Rates per $100 of insured value, Tier 1 county definitions, wind deductible mechanics, and which carriers are still writing in 2026.

Short answer
Commercial property insurance in coastal Georgia and South Carolina in 2026 ranges from
$0.45 to $2.80 per $100 of insured building value, with the typical small-commercial property landing around
$0.95 to $1.40 per $100 outside a Tier 1 wind zone. Properties within 1 mile of the coast (Tier 1) carry
separate wind/hurricane deductibles of 2 to 5 percent of total insured value — not 2-5% of the claim, of the building value. FCCI, ICW, Auto-Owners, Cincinnati, and Westchester are the active SE carriers in 2026.
Rate ranges by construction type and location (2026)
| Construction class | Inland (west of I-95) | Coastal Tier 2 | Coastal Tier 1 |
|---|
| Fire-resistive (steel + concrete) | $0.40 – $0.70 | $0.65 – $1.10 | $1.10 – $1.80 |
| Masonry non-combustible | $0.55 – $0.90 | $0.85 – $1.40 | $1.30 – $2.10 |
| Joisted masonry | $0.70 – $1.20 | $1.10 – $1.80 | $1.65 – $2.60 |
| Frame (wood) | $0.95 – $1.60 | $1.45 – $2.30 | $2.20 – $3.40+ |
Rates are 2026 indicative ranges. Add 15-30% for roof age over 15 years, 10-20% for older HVAC and electrical, and 20-40% for any prior named-storm claim in the last 5 years.
Georgia Tier 1 and Tier 2 wind zone counties
| Tier | Counties | What it means for property insurance |
|---|
| Tier 1 (maximum) | Chatham, Bryan, Liberty, McIntosh, Glynn, Camden | Separate wind deductible required (2-5% of TIV). Limited carrier appetite. State wind pool (GUA) is fallback. |
| Tier 2 (high) | Effingham, Long, Wayne, Brantley, Charlton | Standard market still writes but underwriters look hard at roof age, distance to coast, opening protection. |
| Inland | West of I-95 generally | Standard 2-5% AOP deductible (often a flat $5K or 1%), no separate wind deductible required. |
South Carolina Tier 1 and Tier 2 wind zone counties
| Tier | Counties | Notes |
|---|
| Tier 1 | Beaufort, Charleston, Colleton, Georgetown, Horry, Jasper | SC Wind & Hail Underwriting Association (SCWHUA) is the market of last resort. Charleston and Hilton Head have tightest underwriting. |
| Tier 2 | Berkeley, Dorchester, Williamsburg | Admitted markets still active but with wind sublimit or higher deductible. |
| Inland | Upstate, Midlands | Normal underwriting. AOP deductibles flat or 1% TIV. |
How wind deductibles actually work
The single most-misunderstood thing about coastal commercial property: wind deductibles are percentages of total insured value, not percentages of the claim.
Example: $1,000,000 building, 5% wind deductible, $75,000 partial roof loss from a tropical storm. The deductible is $50,000 (5% of $1M TIV). The owner pays $50,000. The carrier pays $25,000. If the same building had a 2% deductible, the owner would pay $20,000 and the carrier $55,000.
The other dimension is the trigger:
- Named storm deductible — triggers only when the National Hurricane Center has named the storm (tropical storm or hurricane). All other wind events use the standard AOP deductible. Owner-favorable.
- All wind & hail deductible — triggers on any wind or hail event, named storm or not. A spring thunderstorm hail event hits the wind deductible. Owner-unfavorable.
Always confirm which trigger is in your policy. Many small commercial owners learn the difference after the loss.
Carriers still writing coastal SE in 2026
- FCCI Insurance Group — Sarasota-based SE specialist. Writes coastal but selective. Better appetite inland of I-95.
- ICW Group — selective on coastal property. Good when bundled with WC.
- Auto-Owners — mid-market multi-line. Conservative on Tier 1 but flexible on Tier 2.
- Cincinnati Insurance — multi-line bundles. Restrictive on coastal unless other lines balance the exposure.
- Westchester (Chubb subsidiary) — mid-market and specialty. Strong on hospitality and mixed-use coastal.
- Markel — E&S markets. Often the path when standard markets decline.
- Society Insurance — hospitality coastal specialist.
- Georgia Underwriting Association (GUA) — GA wind pool. Last resort for coastal properties that can't get admitted coverage.
- SC Wind & Hail Underwriting Association (SCWHUA) — SC wind pool. Same role.
- Lloyd's of London syndicates (via wholesale) — surplus lines option for hard-to-place coastal accounts.
What kills a coastal property quote in 2026
- Roof age — over 15 years on shingle, over 20 on metal. Single biggest killer.
- No opening protection — no shutters, no impact-rated glass within 1 mile of coast.
- No 4-point inspection — required on buildings over 30 years old at most carriers.
- EIFS (synthetic stucco) without documented inspections — most carriers decline outright.
- Prior named-storm claim in last 5 years — even closed claims load 20-40%.
- Vacancy over 60 days — most policies have a vacancy clause that voids coverage.
- Knob-and-tube wiring or Federal Pacific panel — old electrical kills quotes.
Flood coverage — NFIP vs private
Coastal commercial property is rarely flood-included in the standard property policy. Options:
- NFIP (National Flood Insurance Program) — capped at $500K building / $500K contents for commercial. Reasonably priced in non-V zones, expensive in V zones. Slow claim handling.
- Private flood (Wright Flood, Neptune Flood, FloodFlash) — higher limits available, often cheaper than NFIP in low-risk zones, more expensive in high-risk. Faster claim handling.
- Difference-in-conditions (DIC) policies — wrap-around coverage above NFIP limits. Common on $1M+ buildings.
