Rainfall insurance is commonly used by event organizers, agriculture operations, golf courses, and construction projects to protect against financial losses caused by too much rain.

Because it is considered a specialty coverage, many people assume rainfall insurance must be placed in the surplus lines market with a non-admitted insurer. In reality, that assumption is often incorrect.

In most states, there are at least three admitted insurers capable of providing rainfall insurance, which means the coverage should generally be placed in the admitted market.

Understanding Admitted vs. Non-Admitted Insurance

Insurance companies operate in two main regulatory categories.

Admitted insurers are licensed by the state insurance department. Their policies and pricing must be approved by regulators, and policyholders receive protections such as access to the state guaranty fund if an insurer becomes insolvent.

Non-admitted insurers, often called surplus lines carriers, are not licensed in the state but are allowed to write specialized risks through surplus lines brokers. These insurers typically handle unusual or hard-to-place risks that the admitted market will not cover.

State laws limit when a policy can be placed with a non-admitted insurer, particularly if admitted insurers are available.

The Diligent Search Requirement

Most states require what is known as a diligent search before a broker can place insurance with a surplus lines carrier.

This means the broker must first attempt to obtain coverage from admitted insurers. If admitted insurers are willing to write the policy, the coverage generally must remain in the admitted market.

Typically, brokers must obtain three declinations from admitted insurers before placing coverage with a non-admitted carrier.

Why This Matters for Rainfall Insurance

Rainfall insurance is not a rare or experimental product. Today, multiple admitted insurers actively offer rainfall coverage across the United States.

In fact, most states have at least three admitted rainfall insurance providers available. Because of this, rainfall insurance almost always satisfies the diligent search requirement within the admitted market.

As a result, placing rainfall insurance directly with a non-admitted insurer without first approaching admitted markets may not comply with surplus lines regulations.

Benefits of Using an Admitted Rainfall Insurance Carrier

When rainfall insurance is placed with an admitted insurer, policyholders gain several advantages:

  • Policies regulated by the state insurance department 
  • Greater consumer protections 
  • Access to state guaranty fund protection 
  • Clear regulatory oversight of pricing and policy language 

These protections are one of the main reasons states encourage insurance to remain in the admitted market whenever possible.

Final Thoughts

Rainfall insurance is widely available from admitted insurers across the United States. Because of this, it generally should not be placed in the surplus lines market unless admitted carriers have first declined the risk.

For brokers and policyholders, understanding this distinction helps ensure insurance placements remain compliant with state regulations while still securing reliable weather risk protection.

When properly sourced through admitted insurers, rainfall insurance can provide dependable coverage while maintaining the regulatory protections built into the traditional insurance market.
