Is Charleston SC expensive to live in?

Compared to other coastal cities (Boston, Miami, San Diego), Charleston is more affordable. Compared to the inland South, Charleston is on the higher end. Housing is the biggest variable — Mount Pleasant and downtown are significantly more expensive than Goose Creek or North Charleston.

What is the average property tax in Charleston?

Owner-occupied primary residences in South Carolina are assessed at 4% of fair market value, which is one of the most favorable rates in the country. Investment properties and second homes are assessed at 6%, which can make Charleston rentals less attractive than they look on paper.

Why is homeowners insurance so high in Charleston?

Coastal wind exposure and flood risk. Homes east of the Cooper, on barrier islands, or in FEMA flood zones often need a standard policy plus wind/hail coverage plus flood insurance. Combined premiums can run $3,000–$6,000+ per year on the coast versus $1,200–$1,800 inland.

Is South Carolina a tax-friendly state for retirees?

Yes. Social Security is not taxed, and there is a generous deduction on retirement income for those 65 and older. Combined with the 4% primary-residence assessment, that's a big reason Charleston is a popular retirement destination.

Charleston SC Cost of Living: What It Really Costs in 2026

Charleston's reputation as an affordable coastal city is half true. The headline cost of living sits near the national average, but a few line items — insurance, HOA, flood zones — can flip the math fast. Here's an honest breakdown of what it actually costs to live in Charleston in 2026.

Housing — the big variable

Housing is what makes or breaks your Charleston budget. Rough 2026 benchmarks for single-family homes:

Mount Pleasant: typically $700K–$1.5M+
Daniel Island: typically $750K–$2M+
Downtown Charleston: typically $800K–$3M+ for historic
West Ashley / James Island: typically $400K–$700K
Summerville / Cane Bay: typically $350K–$600K
Goose Creek / North Charleston: typically $275K–$500K

Property taxes — a real advantage

South Carolina taxes owner-occupied primary residences at a 4% assessment ratio, with additional homestead exemptions for owners 65+. A $500,000 primary residence in Charleston County often pays well under $2,500 a year in property tax — significantly lower than comparable homes in many other states. Second homes and investment properties are assessed at 6%, which is an important number for anyone considering a Charleston rental.

Insurance — plan for the real number

This is where Charleston budgets get blown up. Three policies often stack:

Standard homeowners — covers most perils.
Wind / hail — frequently carved out and required separately, especially east of the Cooper.
Flood insurance — required by lenders in FEMA Special Flood Hazard Areas.

Total annual premiums typically run $1,200–$1,800 well inland (Summerville, Cane Bay), $2,500–$4,000 closer to the coast or in older flood zones, and $5,000+ on barrier islands and parts of the peninsula. Always get an insurance quote BEFORE you finalize a budget on a Charleston home.

Utilities

A few realistic estimates for a 2,000 sqft home:

Electric (Dominion Energy): $180–$320/month, higher in summer due to AC.
Water and sewer: $80–$150/month depending on jurisdiction.
Internet: $70–$100/month for gig service.
Trash: included in some areas, $20–$30/month in others.

Food, gas, and the rest

Groceries and gas track close to the national average. Charleston restaurants run premium because of the tourist economy — eating out downtown can rival big-city pricing. Gas tax is among the lower in the Southeast.

HOA dues

Master-planned communities (Daniel Island, Cane Bay, parts of Mount Pleasant) carry monthly HOA dues that fund pools, walking trails, and amenity centers. Typical ranges: $50–$300/month depending on community. Daniel Island and high-end developments can be higher.

The income you actually need

Loose benchmarks for a household to live comfortably (housing under 30% of gross income, savings intact):

Goose Creek / Summerville / Cane Bay: ~$75,000–$95,000
West Ashley / James Island / North Charleston: ~$90,000–$120,000
Mount Pleasant / Daniel Island / Downtown: ~$150,000–$250,000+

The bottom line

Charleston is affordable if you treat it like a coastal city, not an inland one.
