What the NAIC does (and what it does not)

The National Association of Insurance Commissioners is the organization the state insurance regulators run together. It was founded in 1871, and according to its About page it is governed by the chief insurance regulators of the 50 states, the District of Columbia and five U.S. territories. It writes model laws, sets up shared systems for filings and financial oversight, and publishes the data most homeowners-insurance statistics come from. It cannot approve your rate, order a claim paid or fine an insurer. Those powers belong to your state.

If you have ever read "the average homeowners premium was $1,737," or looked up a company's complaint record, you have used NAIC work.

What the NAIC is, and is not

It is a membership body of regulators, not a government agency. Its members are the people who run each department of insurance, so its positions reflect what the state commissioners agree on. Because insurance is regulated state by state (who regulates homeowners insurance?), the NAIC exists to keep fifty-plus separate regulators from working in complete isolation.

What follows from that:

• It has no enforcement power over insurers. Only a state (or a court) can fine, restrict or shut down a company.
• Its products are not law until a state adopts them. A state legislature or department must pass a model as its own.
• States can and do depart from it. Two states can adopt the same model law with different wording, or ignore it.

The work the NAIC does

Model laws and regulations

The best-known output is the model law: a template that states can adopt in whole, in part or with changes. For homeowners, models matter in areas like unfair claim settlement practices. The NAIC's claims model regulation sets time standards, for example 15 days to acknowledge a claim and 21 days after proof of loss to accept or deny it. Many states have adopted something close, but the actual deadline in your state is whatever your state's statute or regulation says. See unfair claims settlement practices laws and how long insurers have to pay a home claim.

Financial oversight and accreditation

State regulators are responsible for insurer solvency, and the NAIC supports them with shared financial reporting formats, analysis tools and a peer-review accreditation program. State departments are reviewed against agreed standards for how they supervise insurer finances. For a homeowner this is the quiet part of the system: it exists so that the company holding your policy can pay claims after a hurricane. When it does not work, the state guaranty fund pays covered claims (property and casualty guaranty funds explained).

SERFF: the filing pipeline

The NAIC operates SERFF, the System for Electronic Rate and Form Filing. According to the NAIC's SERFF page, insurers use it to send rate and form filings to regulators, and regulators use it to review them. A separate public side, SERFF Filing Access, lets anyone search many state filings through the state's own portal. What shows up varies by state: filings marked confidential can be withheld, and some states route you to a public-records request for the rest. If you are curious why your insurer says it asked for a particular increase, this is where the actuarial exhibit lives. See how insurers file rate increases with regulators.

Data and reports

This is the NAIC output you are most likely to meet:

• Market share reports. The NAIC's annual market share reports rank insurers by direct premiums written, nationally and by state. Reports cited across this site put the 2025 homeowners multiple peril market at $188.95 billion, with State Farm holding 18.67 percent (market share data, NAIC, August 2026).
• The homeowners average premium report. The NAIC's report for data year 2023, published July 2026, put the average HO-3 premium at $1,737 nationally, with Louisiana highest among the states at $3,027 and Wisconsin lowest at $923. Averages like these are blunt, and the sources and years matter. See how much does homeowners insurance cost?.
• Complaint data. The NAIC's Consumer Insurance Search compiles closed, confirmed complaints reported by state departments, which underlie the NAIC complaint index. See How to use the NAIC complaint index to compare home insurers for how to read it.

Training, coordination and policy work

Committees of regulators work on live questions: catastrophe modeling, climate-related risk, insurer exits and availability. These produce white papers, data calls and, sometimes, model changes. They are useful for understanding where regulators are heading, but a committee discussion is not a rule.

Criticisms worth knowing

The NAIC has its critics from both directions. Some consumer advocates argue that it is too close to the industry its members oversee and that voluntary models move slowly. Industry groups and some federal policymakers argue that fifty state systems create delay and inconsistency, especially in rate and form approval, and that a single national standard would be more efficient. Others reply that state regulators are closer to local conditions such as hurricane exposure or hail. The debate over a larger federal role is covered in the federal role in home insurance.

How to use the NAIC as a homeowner

1. Look up a company's complaint record in the NAIC Consumer Insurance Search before you buy, then compare it with your state department's own figures, which may use a different formula.
2. Check market share to see who writes most of the homeowners business in your state. Size is not quality, but it tells you whether a company is a major player.
3. Read the NAIC's average-premium report for context on where your state stands, remembering that the report reflects an earlier data year than today's quotes.
4. Search SERFF Filing Access on your state's department site if you want to read an insurer's rate filing.
5. File complaints with your state, not the NAIC. The NAIC does not take or resolve complaints about your insurer. See how to file a complaint with your state insurance department.

What the NAIC does not do

It does not rate insurers' financial strength (that is AM Best, Demotech, S&P and others), it does not license agents, and it does not set rates. It does not name the best company. The compare home insurers side by side tool on this site draws on its data, but any comparison is only as good as the year and method behind the numbers.

Key takeaways

• The NAIC is the association of state insurance regulators, founded in 1871; it is not a federal agency and has no enforcement power.
• Its model laws apply only after a state adopts them, so your state's actual law controls.
• It runs SERFF and publishes market share, premium and complaint data that most homeowners-insurance statistics rely on.
• Take complaints and claim disputes to your state department, not the NAIC.
• When you cite an NAIC figure, note the year; the data lags the market.
