The rate hike, which goes into effect Dec. 1, varies widely depending on where the mobile home is located.

Rates on mobile homes in the Triangle will increase either 2.9 percent or remain the same, depending on the type of mobile homeowners' policy they have. But increases in 18 coastal counties will rise 24 percent or more.

The state Department of Insurance today announced a settlement with the N.C. Rate Bureau, which represents the state's property and casualty insurers. In May, the Rate Bureau requested rate increases that averaged 23.9 percent, the first time it sought a rate change in more than a quarter-century.

The Insurance Department estimates the settlement will save consumers $25 million a year in premiums compared to the rate increase initially sought by the bureau.

"I hope consumers will understand that it was about time for us to raise rates enough to allow these companies to keep offering coverage for mobile homes -- but at the same time keeping rates affordable overall," said Insurance Department spokeswoman Chrissy Pearson.

Pearson said the significantly higher rates in coastal counties reflect the fact that insuring mobile homes is riskier in coastal areas because of their susceptibility to wind damage.

Ray Evans, general manager of the Rate Bureau, couldn't be reached for immediate comment.
