ISO Scores 202: ISO Scores by State

An ISO score is a critical tool for measuring public safety — so much so that insurance companies are willing to stake policy decisions on it. While these scores are issued at the community level, it’s important to think about them in a wider context, especially since many fire departments rely on state funding.
So which states are doing the best — and the worst — when it comes to ISO scores? Learn the answer and see how some are raising the bar and improving their ratings in this guide to state ISO scores.

How ISO Scores Affect Communities & Why State ISO Scores Matter

ISO Scores primarily affect homeowners and businesses in the community in two ways: psychologically and financially. ISO scores are a measure of how well the fire department can protect the community.

If the rating is low, residents and business owners likely feel safer knowing firefighters can help them when needed. The financial impact of ISO ratings lies in the effect they can have on insurance premiums. In many areas, property insurance underwriters use local area scores to determine the risk of property damage claims.

If the score is too high, there may be a higher likelihood of having to pay out claims. If the score is low, that can signal lower risk. These ISO-based risk assessments can factor into the premiums insurance companies charge and, in some cases, whether they’ll offer a policy at all.

For this reason, fire departments and even state governments need to view improving ISO scores as a long-term investment in residents and business owners. Doing so reduces fire risk, makes communities safer, and even reduces financial risk. It also restores public faith and trust in the very entities designed to protect people.

Top States With the Best ISO Scores

ISO scores on the lowest end of the spectrum are pretty uncommon. However, a few states and territories have managed to achieve them. In Florida, 110 fire departments have earned an ISO score of two. Two is the most common rating among all Florida fire departments.

Still, some departments are doing even better than that. For example, the Key West Fire Department has been able to maintain an ISO Score of one, something only 1% of departments across the nation have managed.

Surprisingly, the state of California has many departments with an ISO score of two. Major areas like Riverside, Vallejo, and Fairfield, which all share the same score of two, have put a lot of work into ensuring that scores stay low and communities remain safe.

Washington, D.C., isn’t technically a state, but it still deserves to be mentioned in this conversation. It has just one fire department, but that one is doing very well, with an ISO score of two. Other honorable mentions include South Carolina and Rhode Island.

When it comes to common factors that drive these high ratings, some of the answer lies in effective training programs. For example, the Florida Keys invested $1.96 million in its 5,000-square-foot live fire training facility in 2017. Riverside, California hired more firefighters and paramedics as well as increased trucks by 25%.

Like many other cities, Washington, D.C., hopped on the public-private trend to build fire stations in private buildings, which saves money on infrastructure. Those are dollars that can be reinvested into initiatives that lower ISO scores — something D.C. is clearly good at doing.


States With Room for Improvement

Though some states are doing well, others have a higher-than-average number of fire departments with scores of eight or higher. Some of these states include:

  • Maine
  • Vermont
  • New Hampshire
  • North Dakota
  • South Dakota
  • New York
  • Michigan
  • Nevada
  • Indiana

There are many possible reasons for these higher scores. In some cases, rural areas may not have as much access to water. If regions are not well populated, there aren’t as many people to pay taxes and contribute to the public safety budget. As a result, there could be a lack of funding for new equipment, new infrastructure, or more personnel.

State-by-State Comparison of ISO Scores

The national average for ISO scores is roughly 5.5. The 20 states with scores higher than that average include:

  • Wyoming
  • Maine
  • New Hampshire
  • Vermont
  • Pennsylvania

  • North Dakota
  • South Dakota

The 23 states not appearing on these lists fall below the national average when it comes to ISO scores.
