Prohibits increases in rates of homeowners' insurance in excess of twenty-five percent per year

S 6356 caps annual homeowners' insurance rate increases at 25% per year, meaning insurers cannot raise premiums more than 25% above the previous year's rate without the policyholder's prior written agreement. This directly affects homeowners whose insurance policies are renewed or modified, preventing sudden, large premium hikes without consent. The bill requires insurers to obtain explicit policyholder approval before implementing any rate increase exceeding the 25% threshold. It applies to all new, renewed, or modified homeowners' insurance policies issued after the law's effective date (90 days after enactment).
