The Ultimate 2025 Guide to the South Carolina Home Insurance Market

South Carolina home insurance averages $2,708 a year, above the U.S. average. Hurricanes, flooding, and coastal risks drive rising premiums.

South Carolina's homeowners insurance market continues to face significant pressure in 2025, with average premiums reaching $2,708 annually for policies with $250K in dwelling coverage, placing the state above the national average. The Palmetto State's unique coastal geography and increasing frequency of severe weather events have created a challenging environment for both insurers and homeowners.

Market Overview and Current Rates

The South Carolina insurance landscape reflects the state's vulnerability to natural disasters. South Carolina's average homeowners insurance premium is $2,708 for policies with $250K in dwelling coverage, $125K in personal property coverage and $200K in liability coverage, which is more than the $2,423 national average. This places South Carolina as the 15th most expensive state in the country for home insurance, at 3% above the national average.

Premium variations across the state are substantial, with premiums ranging from $1,968 to $4,772 depending on location. Coastal areas bear the heaviest burden, with Charleston's average at $3,270 and Myrtle Beach residents potentially seeing rates as high as $4,772, while inland areas like Columbia may pay around $1,968 annually.

Rising Premium Trends and Market Pressures

The state has experienced notable rate increases, with hurricane damage fueling increases and projecting home insurance rates in South Carolina will increase another 11% by the end of the year. According to industry reports, South Carolinians already pay 29% more than the average U.S. homeowner.

Recent data shows concerning trends in the market. South Carolina homeowners have seen relatively mild increases in their home insurance rates in the 2020s, with the biggest increase being 9.2% in 2024, though this varies significantly by carrier, with Travelers experiencing a 38.7% increase over six years while Allstate saw just a 6.5% increase.

Major Risk Factors and Coverage Considerations

Hurricane and Wind Damage

South Carolina's 200-mile coastline makes it particularly susceptible to hurricane damage. The state is among 19 states that have hurricane or named storm deductibles, with these deductibles typically ranging from 1-5% of Coverage A. Wind and hail deductibles are percentage-based, meaning if a house insured for $300,000 has a 3% wind and hail deductible, the homeowner's out-of-pocket deductible would be $9,000.

Flood Insurance Requirements

Standard homeowners policies exclude flood damage, making separate flood insurance critical. Flood insurance is not included in standard HO-3 policies and is mandatory in FEMA flood zones. Homeowners can obtain coverage through the National Flood Insurance Program (NFIP) or private insurers.

Earthquake Coverage

Despite being less commonly discussed, South Carolina lies on a minor fault line, and earthquake coverage should be offered in areas like Columbia and the Midlands.

Essential Endorsements for South Carolina Homeowners

Given the state's risk profile, several endorsements are particularly valuable:

  • Water Backup/Sump Overflow: Critical for low-lying and coastal homes
  • Ordinance or Law Coverage: Ensures code compliance when rebuilding older homes
  • Service Line & Equipment Breakdown: Protects aging infrastructure and appliances
  • Extended Replacement Cost: Needed for storm rebuild cost spikes

Impact of Credit Scores and Home Characteristics

Credit scores significantly impact premiums in South Carolina. Homeowners with poor credit pay an average of $13,805 annually, which exceeds the state average by $11,097, while those with excellent credit pay $1,822 annually.

Construction materials and roof types also play crucial roles. Homes with tile roofs may see lower premiums due to the material's durability, while shake-treated roofs could lead to higher insurance costs. Additionally, insuring a newly constructed home costs $1,534 annually, $1,174 lower than the $2,708 average for existing homes.

Coastal Area Challenges

Coastal homeowners face unique challenges beyond higher premiums. Vacation and seasonal homes are common along the coast and require verification of occupancy type and carrier eligibility. Many properties feature stilted/elevated construction that may require special underwriting. However, hurricane clips and metal roofs can qualify for wind mitigation discounts with select carriers.

The state operates the South Carolina Wind and Hail Underwriting Association (SCWHUA) as an insurer of last resort for coastal properties. The SC Wind and Hail Association pool was designed as a compromise between the State of South Carolina and many insurance carriers whose writings had become too saturated along the coast.

Leading Insurance Carriers

Several insurers offer competitive rates and coverage in South Carolina:

  • American National: Has quoted some of the lowest homeowners insurance rates for South Carolina homeowners, with sample policies costing $1,052 per year for $350,000 of dwelling coverage in certain circumstances
  • Allstate: Based on sample quotes for $350,000 of dwelling coverage as of 2025, Allstate's average premiums were approximately 42% lower than the statewide average. Individual premiums may vary based on location, coverage, and other factors
  • Auto-Owners: According to NAIC complaint data, Auto-Owners received fewer complaints relative to its market share than many similarly sized insurers, though premiums average around $2,517 per year, which is approximately 10% above the state average

Note: All rate information is based on sample quotes and averages. Actual premiums vary based on individual circumstances, coverage selections, and underwriting factors.

Enhancing Customer Service Through Strategic Partnerships

A warm transfer to Covered as an insurance partner can help improve the customer experience by connecting customers with additional coverage options and insurance guidance. This approach may help shift customer service toward becoming a more value-added function by addressing key insurance concerns, though results will vary based on implementation and customer needs.

Disclosure: Covered may receive compensation from partner insurers if a customer purchases a policy through their platform.

Market Outlook and Recommendations

The South Carolina homeowners insurance market faces continued challenges from increasing storm frequency and severity. Experts project rates will continue rising, with projections of another 11% increase by year-end.

Homeowners should consider several strategies:

  1. Annual Shopping: Compare quotes from several insurers annually, as different companies rate risks differently
  2. Home Improvements: Making improvements to your house might help lower insurance rates
  3. Risk Mitigation: Installing hurricane shutters, impact-resistant windows, and fortified roofing can qualify for discounts with some carriers
  4. Deductible Management: Balancing higher deductibles against premium savings while maintaining adequate liquidity

Conclusion

South Carolina's homeowners insurance market reflects the state's unique geographic challenges and growing climate risks. While premiums continue to rise, understanding the market dynamics, available coverage options, and risk mitigation strategies can help homeowners navigate this complex landscape. The key lies in working with knowledgeable insurance professionals who understand both the state's specific risks and the evolving insurance marketplace.
