Homeowner Insurance Guide for South Carolina
South Carolina homeowners pay an average of $2,500 per year for insurance — about $200 above the national average of $2,300. The state’s lengthy Atlantic coastline exposes it to hurricanes, while inland areas face severe thunderstorms, tornadoes, and flooding. Hurricane Hugo (1989), Hurricane Matthew (2016), and Hurricane Florence (2018) all caused billions in damage, keeping SC premiums high.
Average Homeowner Insurance Cost in South Carolina

| Premium (HO-5) | $500,000 | $4,200 |
What Drives Insurance Costs in South Carolina
Hurricanes: SC’s coast from Myrtle Beach to Hilton Head faces direct hurricane exposure. Hugo (1989) devastated Charleston with $7 billion in damage. Matthew (2016) and Florence (2018) caused catastrophic inland flooding. Coastal policies carry hurricane deductibles of 2–5%.
Flooding: SC is exceptionally flood-prone. The October 2015 floods — from a non-hurricane rain event — caused $1.5 billion in damage across the Midlands. Rivers including the Pee Dee, Santee, Congaree, and Savannah flood during heavy rains and hurricane remnants.
Severe storms and tornadoes: SC averages 15–20 tornadoes per year. Severe thunderstorms bring wind and hail damage across the Upstate (Greenville, Spartanburg) and Midlands (Columbia).
Coastal growth: Myrtle Beach, Charleston, and Hilton Head continue rapid development, placing more homes in hurricane and flood zones.
Required vs Optional Coverage
Included in Standard HO-3
- Fire, smoke, and lightning
- Wind (hurricane deductible for coastal counties)
- Hail
- Theft and vandalism
- Liability ($100,000–$500,000)
- Additional living expenses
Not Included — Separate Policies Needed
- Flood insurance: Essential across much of SC. NFIP policies run $700–$1,500/yr. The 2015 floods and Hurricane Florence proved that devastating flooding occurs far inland. If you’re buy a home in SC, budget for flood coverage.
- Earthquake coverage: Charleston sits on a seismic zone — the 1886 Charleston earthquake (estimated magnitude 7.3) was the most damaging earthquake in the eastern U.S. Endorsements cost $100–$400/yr. Strongly recommended for the Lowcountry.
How to Lower Your South Carolina Homeowner Insurance
- Fortified roof: IBHS Fortified designation saves 25–55% on coastal wind premiums. SC actively promotes this program. Contact certified roofers.
- SC Safe Home Program: Grants up to $5,000 for hurricane mitigation improvements
- Bundle policies: 15–25% savings
- Higher deductible: $1,000 to $2,500 saves 10–15%
- Claims-free discount: 3+ years earns 10–20% off
- Wind mitigation: Hurricane straps, impact windows, hip roofs earn 5–15% coastal discounts
- Security system: 5–10% for monitored alarms
- New roof: Use the estimate maintenance costs to budget.
Choosing the Right Coverage Level
When setting up your South Carolina homeowner policy, you need to decide on three key coverage amounts. Dwelling coverage should equal your home’s full replacement cost — not the market value or purchase price, but what it would actually cost to rebuild from the ground up at current material and labor prices. Many homeowners are underinsured because they haven’t updated their dwelling coverage to reflect construction cost inflation. Get a replacement cost estimate from a local contractor or use your insurer’s cost estimator tool.
Personal property coverage (typically 50–70% of dwelling coverage) protects your belongings inside the home. Standard policies pay actual cash value (depreciated value) for personal property. Upgrading to replacement cost personal property coverage adds 10–15% to your premium but pays to replace items at today’s prices without depreciation. For expensive items like jewelry, artwork, or electronics, you may need scheduled personal property endorsements with specific coverage limits.
Liability coverage protects you if someone is injured on your property or you accidentally damage someone else’s property. Standard limits range from $100,000 to $500,000. Given that a single slip-and-fall lawsuit can exceed $300,000, carrying at least $300,000 in liability coverage is advisable. An umbrella policy ($200–$400/yr for $1 million) extends your liability protection beyond your homeowner policy limits — valuable for homeowners with pools, trampolines, or dog breeds that some insurers consider high-risk.
Filing a Claim in South Carolina
SC’s Department of Insurance requires insurers to acknowledge claims within 15 days and settle or deny within 30 days of complete documentation.
- Prevent further damage: Tarp roofs, remove water, board openings. Save receipts.
- Separate wind and flood claims: Wind (HO-3) and flood (separate policy) require different filings after coastal storms.
- File immediately: After hurricanes, early filing gets faster response.
- Get contractor estimates: 2–3 bids from SC-licensed contractors.
- Dispute resolution: SC Department of Insurance: (803) 737-6160 or (800) 768-3467.

Shopping for Coverage in South Carolina
South Carolina’s insurance market reflects its Lowcountry hurricane coast with inland severe storm corridor. Getting the best rate requires more than accepting the first quote. Follow this approach to find the right balance of coverage and cost.
Get at least 3-5 quotes. Contact a mix of national carriers (State Farm, Allstate, USAA if eligible), regional mutuals, and independent agents who represent multiple companies. Independent agents are particularly useful in South Carolina because they can compare policies from carriers that specialize in hurricanes coverage. Online comparison tools give quick estimates, but an agent familiar with South Carolina’s risk profile can identify discounts you might miss.
Review coverage limits carefully. SC Wind and Hail Underwriting Association covers coastal properties — mandatory separate wind deductible of 2-5%. Ask each insurer exactly what triggers this deductible versus your standard deductible. Also confirm that replacement cost coverage keeps pace with local construction costs — rebuilding in South Carolina after a major hurricanes event can be 20-40% more expensive than normal due to contractor demand surges. Use our closing costs by state tool to understand the full cost picture.
Check insurer financial strength. After a major hurricanes event, you need an insurer that can pay claims promptly. Verify AM Best ratings (A or higher) and check complaint ratios through the SC Department of Insurance at (803) 737-6160. A low-cost policy from a financially weak carrier is no bargain if claims processing stalls. Compare state tax implications alongside insurance when evaluating total housing costs.
Understanding Your South Carolina Declarations Page
Your declarations page (or “dec page”) is the summary document attached to your homeowner policy. It lists your coverage amounts, deductibles, premium breakdown, and endorsements in one place. Review it annually — especially after any policy renewal, home renovation, or hurricanes season.
Key items to verify on your South Carolina dec page:
- Dwelling coverage (Coverage A): Should match current replacement cost, not market value or purchase price
- Deductible structure: Check whether hurricanes damage has a separate percentage-based deductible
- Endorsements: Confirm any added coverage for severe thunderstorms or other South Carolina-specific risks is listed
- Liability limits: Verify at least $300,000 in personal liability (Coverage E)
- Loss of use (Coverage D): Confirm adequate additional living expenses if your home becomes uninhabitable
If anything looks wrong, contact your agent before the next premium due date. Policy corrections mid-term are usually free. Keep your dec page with your other insurance documents for easy reference.
FAQ
What is a hurricane deductible in SC?
Coastal SC policies carry hurricane deductibles of 2–5% of dwelling coverage. On a $300,000 Charleston home with a 3% deductible, you’d pay $9,000 before insurance kicks in. Factor this into your mortgage planning.
Do I need earthquake insurance in Charleston?
Yes. Charleston’s 1886 earthquake (estimated 7.3 magnitude) caused catastrophic damage. The fault is still active. Endorsements cost $100–$400/yr with 10–15% deductibles. For Lowcountry properties, this is strongly recommended. Your escrow can fund this coverage.
How does flooding affect inland SC?
The October 2015 floods proved that catastrophic flooding can strike anywhere in SC. Columbia, Sumter, and Midlands communities experienced devastating flooding from a non-hurricane rain event. NFIP policies start at $400/yr for lower-risk areas. Include this in closing costs. Building home equity near waterways requires flood protection. Use a payment calculator to budget.
What is the SC Safe Home Program?
SC Safe Home provides grants up to $5,000 for hurricane mitigation improvements including roof reinforcement, hurricane shutters, and window protection. Income-eligible homeowners may receive additional assistance. Check eligibility through the SC Department of Insurance.
Does SC have a FAIR Plan?
SC’s Wind & Hail Underwriting Association provides wind coverage for coastal properties. The SC FAIR Plan provides basic coverage for properties unable to find voluntary market insurance.
Does my credit score affect SC insurance?
Yes. South Carolina allows credit-based insurance scoring. Good credit saves 20–30%.
How often should I shop for new insurance quotes in South Carolina?
At least every 2-3 years, or immediately after a rate increase above 10%. South Carolina’s market for hurricanes coverage shifts frequently as carriers enter and exit the state. After major hurricanes events, some insurers restrict new policies while others see an opportunity. An independent agent monitoring South Carolina’s market can alert you to better options. Always compare the full policy — not just the premium — since coverage limits and deductible structures vary significantly between carriers.
What should I do if my insurer drops my South Carolina policy?
South Carolina requires insurers to provide advance written notice before non-renewal (typically 45-60 days). Use that time to get quotes from other carriers through an independent agent. Contact the SC Department of Insurance ((803) 737-6160) if you cannot find coverage in the voluntary market — they can direct you to residual market options. Document your home’s condition and any risk-mitigation improvements, as these strengthen your application with new insurers. Visit the South Carolina real estate guide for more housing resources.

South Carolina Natural Disaster Risks and Insurance
South Carolina’s primary natural disaster risks include hurricanes and flooding. Standard HO-3 homeowner policies do NOT cover flood damage — that requires a separate flood insurance policy through NFIP (National Flood Insurance Program) or a private carrier. NFIP flood insurance averages $700-1,500 per year nationally, but rates vary significantly by flood zone designation.
If your home is in a FEMA-designated Special Flood Hazard Area, your mortgage lender will require flood insurance. Even outside these zones, roughly 25% of flood claims come from properties in moderate-to-low risk areas. Consider the cost of a separate policy when budgeting for your South Carolina home. For earthquake or wind coverage gaps, ask your insurer about endorsements or standalone policies. Use our closing costs tool to factor insurance premiums into your total monthly housing cost.
How Claims History Affects Your South Carolina Premium
Insurance companies check your CLUE (detailed Loss Underwriting Exchange) report when quoting your premium. This report tracks your personal claims history for the past 5-7 years AND the claims history of the property itself. Two or more claims in five years can increase your premium by 20-40%, and some carriers may decline to renew after three claims.
For minor damage under $2,000, consider paying out of pocket rather than filing a claim. The premium increase from a claim often exceeds the payout over 3-5 years. Before buying a home in South Carolina, request a CLUE report on the property to check for prior claims — this is free and gives you insight into potential insurance cost surprises. Review your home equity position before deciding whether to absorb repair costs or file claims.
How Your Home’s Age Affects Insurance in South Carolina
Older homes in South Carolina often cost more to insure. Homes built before 1980 may have outdated electrical wiring (knob-and-tube or aluminum), original plumbing (galvanized or polybutylene pipes), and older roof materials — all of which increase risk and premiums. Some insurers require a 4-point inspection (roof, electrical, plumbing, HVAC) for homes over 30 years old before issuing a policy.
Upgrading your roof is the single most effective way to lower your premium — a new roof can reduce costs by 10-25%. Similarly, replacing old electrical panels and plumbing can remove surcharges. Check our renovation ROI calculator to see which upgrades make financial sense for both insurance savings and resale value. Our maintenance cost estimator helps you budget for keeping your home in insurance-friendly condition.
