Population: 50,801 | South region | 8% above national average for homeowners insurance
Summerville is a small city with a population of 50,801 in the South region. Insurance costs here are shaped by a combination of South Carolina's regulatory environment, local risk factors, and the city's specific demographic profile.
Homeowners insurance in Summerville runs $2,815/yr, which is roughly in line with the national average of $2,600/yr. While not the cheapest market in the country, residents aren't paying the extreme premiums seen in high-risk areas like coastal Florida or tornado-prone Oklahoma.
Hurricane exposure is the dominant factor in Summerville's insurance pricing. Properties near the coast face windstorm surcharges that can add 30-50% to base premiums, and many insurers require separate hurricane deductibles (typically 2-5% of dwelling value). Wind mitigation features — hurricane shutters, roof clips, and impact-resistant roofing — can earn substantial premium credits and are strongly recommended for Summerville homeowners.
Summerville's crime index of 28/100 is moderate — neither a significant penalty nor a notable benefit for insurance pricing. Standard security measures and a claims-free history are the most effective ways to keep premiums in check.
The total annual insurance budget for a Summerville homeowner with a car is approximately $4,656/yr ($388/mo). This is roughly in line with the national combined average of $5,097/yr. Insurance costs in Summerville are neither a major burden nor a particular advantage. Bundling homeowners and auto with the same carrier typically saves 15-20%, which could mean $792 in annual savings.
