NAIC Launches Nationwide Homeowners Data Call as Market Pressures Intensify

The National Association of Insurance Commissioners is launching a nationwide homeowners market data call that will collect ZIP code-level data across the United States. Regulators described the effort as the most comprehensive collection of homeowners insurance policy data undertaken to date.

Announced at the NAIC’s spring national meeting, the initiative aims to give state regulators a detailed view of how homeowners coverage is priced, underwritten, and maintained across different geographies and perils. Availability and affordability remain key areas of focus.

Scope and Timing of the Data Call

Insurers writing at least $50,000 in relevant homeowners premiums must submit data by June 15. The submission will cover policy years from 2018 through 2025, with a public report expected in early 2027.

The NAIC is requesting detailed information, including policy type, premiums, claims and losses by peril, deductibles, cancellations and nonrenewals, coverage limits, valuation methods, and mitigation discounts.

Regulators plan to use the data to assess how policy terms and deductibles affect cost and access. They will also evaluate mitigation efforts, monitor carrier financial strength, and review consumer awareness of insurance coverage.

Florida Insurance Commissioner Mike Yaworsky, chair of the NAIC’s Homeowners Market Data Call Task Force, said the effort will provide regulators with additional tools and resources to support preparation ahead of severe weather events.

The initiative builds on a 2024 agreement between the US Treasury’s Federal Insurance Office and the NAIC to standardize and share homeowners insurance data. Treasury previously warned that climate-related events were increasing costs and reducing availability in several regions.

Market Conditions Driving the Initiative

The data call comes as pressures continue to affect the homeowners insurance market. A January 2025 Treasury report found that costs are rising while availability is declining, particularly in areas exposed to wildfires, hurricanes, and convective storms.

From 2018 through 2023, insurers of last resort in California, Florida, and Louisiana saw policy counts roughly double as private carriers pulled back. Florida’s Citizens Property Insurance Corporation grew to about 1.4 million policyholders, becoming the state’s largest home insurer.

Carrier actions have also shaped the market. In 2023, State Farm and Allstate paused new homeowners business in California, citing wildfire risk and inflation. State Farm later sought a double-digit rate increase in 2025 following major wildfire losses.

In Florida, legislative reforms have spurred some new capital investment. However, Citizens still holds more than 1.3 million policies, and estimates indicate that about one in five homeowners in the state has no insurance coverage.

Weiss Ratings analysis of NAIC data showed that Florida and California recorded the highest rates of policyholder drops in 2024, while Louisiana experienced the sharpest increase in nonrenewal rates over the past five years.

Industry Perspective on Data Collection

Industry groups said the data call will require significant reporting effort but acknowledged its role in improving transparency.

Erica Weyhenmeyer, policy vice president for market regulation and workers’ compensation at the National Association of Mutual Insurance Companies, said the design reflects progress in transparency and execution. She added that the focus on affordability, availability and catastrophe risk aligns with current regulatory discussions.

Parallel Focus on Artificial Intelligence Oversight

At the same meeting, the NAIC provided an update on its Artificial Intelligence Systems Evaluation Tool, which is being piloted with volunteer insurers in 2026.

The tool is designed to help regulators evaluate how insurers govern and monitor AI systems used in underwriting, claims and marketing. The NAIC plans to refine the tool based on feedback and release it for public comment later in 2026, with formal adoption targeted for the fall national meeting.

This work builds on the NAIC’s 2023 AI Model Bulletin, which established principles for responsible AI use in insurance.
