South Carolina Insurance Guide 2026

South Carolina Insurance Market Overview

Last updated: July 2026

The average cost of home insurance in South Carolina is $1,950 per year (about $163/month), while the average auto insurance premium runs $1,650 per year. Hurricane exposure along the coast is the main home-insurance cost driver, with the highest rates in coastal counties.

Premiums are highest around Charleston, Columbia, North Charleston, Mount Pleasant, and lower in rural counties where claims frequency is smaller.

How South Carolina Compares Nationally

South Carolina ranks #14 of 50 states for home-insurance cost and #25 of 50 for auto insurance. Home premiums here are about 10% above the U.S. state average of $1,771 (+$179), and auto premiums are roughly in line with the national average of $1,679 (-$29).

Put together, a typical South Carolina household carrying both policies budgets about $3,600 per year — roughly $300 per month — before discounts, deductible choices, or flood add-ons.

South Carolina Insurance Cost Snapshot

South Carolina's Local Risk Profile

South Carolina's coast from Hilton Head to Myrtle Beach carries full hurricane exposure, with named-storm deductibles standard and the South Carolina Wind and Hail Underwriting Association backstopping beachfront wind. Inland, rates drop quickly. Auto premiums trend above average, pushed by high accident-fatality rates and roughly one in ten drivers being uninsured.

💡 South Carolina shopping tip: Coastal buyers should get a wind-mitigation inspection — documented fortification earns meaningful credits from the wind pool and private carriers alike.

What Drives South Carolina Insurance Rates

Several state-specific factors explain why South Carolina sits where it does on the national cost curve:

• Minimum auto liability law: South Carolina requires at least 25/50/25 in liability coverage.
• Fault system: South Carolina is an at-fault (tort) state — the driver who caused the crash is responsible for the damages.
• Flood exposure: South Carolina carries a high flood risk, which affects both home-insurance pricing and the value of a separate flood policy.
• Local perils: Hurricane risk along coast. No individual mandate for auto beyond financial responsibility.
• Population & claims density: Urban centers like Charleston concentrate traffic and property claims, pushing rates above rural parts of the state.

Auto Insurance in South Carolina

The minimum auto insurance liability requirements in South Carolina are 25/50/25 (bodily injury per person / bodily injury per accident / property damage, in thousands). Driving without at least the state minimum can lead to fines, license suspension, and vehicle impoundment.

With South Carolina auto premiums averaging $138/month (roughly in line with the national average), comparing quotes matters here — see our guide to lowering car insurance for tactics that work in any state.

Home Insurance in South Carolina

A standard South Carolina homeowners policy (HO-3) covers the dwelling, detached structures, personal belongings, liability, and additional living expenses. Because South Carolina faces high flood risk, buyers in higher-risk zones should plan for a separate National Flood Insurance Program (NFIP) or private flood policy — standard home insurance explicitly excludes flood damage. For the full breakdown of what an HO-3 covers and excludes, read What Is Homeowners Insurance.
