25 Commercial Property Insurance Statistics Every Business Owner Should Know
Commercial property premiums, falling 2026 rates, storm and fire losses, building counts, and underinsurance, in 25 cited statistics from the NAIC, NFPA, NOAA, Triple-I, EIA, and other primary sources.
Commercial property insurance protects the buildings, equipment, inventory, and income a business runs on, and in 2026 the market behind it is moving in two directions at once. Prices for commercial property insurance are falling after years of steep increases, while severe storms, fires, and outdated building valuations keep the underlying risk high. This report gathers 25 cited statistics on how large the market is, where rates are heading, what fire and severe weather cost, and how many properties carry too little coverage. Every figure comes from a regulator, a government agency, an industry body, or an insurer’s or broker’s own published research, and each one states the year it describes.
Key Takeaways
- The market is large - commercial multiple peril policies generated $70.1 billion in direct premiums written in 2025.
- Rates are falling fast - U.S. commercial property rates dropped 13% in the second quarter of 2026.
- Underwriting results improved sharply - the direct loss ratio on the property side of commercial package policies fell to 38.8% in 2025, down from 66.0% in 2021.
- Storms drive the biggest losses - severe convective storms caused $52.3 billion of the $103.1 billion in U.S. insured catastrophe losses in 2025.
- Fire never takes a year off - there were 119,500 non-residential structure fires in 2024, causing $3.6 billion in direct property damage.
- Underinsurance is widespread - an industry study cited by The Hanover estimates more than 70% of U.S. commercial properties are underinsured by at least 40%.
How big the commercial property insurance market is
1. Commercial package policies brought in $70.1 billion in 2025
Commercial multiple peril (CMP) policies, the package contracts that combine property and liability coverage for a business, produced $70.1 billion in direct premiums written in 2025, according to the NAIC’s 2025 Market Share Report published in August 2026. The NAIC reports CMP as a single total for market share purposes, so the figure includes both the property and liability portions. It is the broadest single measure of what businesses spend to insure their premises and contents in a package. For an owner, it means the product you are buying sits inside one of the largest commercial lines in the country.
2. Fire and allied lines added more than $63 billion
Not all property coverage is written as a package. The NAIC recorded $32.5 billion in direct premiums for the fire line and $30.7 billion for allied lines in 2025. These lines include some personal property policies as well as commercial ones, so treat them as a broad measure of property coverage written outside of packages. Together, the two lines are nearly as large as the entire CMP market.
3. Property premiums grew 8.9% to 12.4% in 2024
Before rates turned, premiums climbed quickly. In 2024, direct premiums for the property portion of CMP rose 8.9% to $45.5 billion, while the fire line rose 12.4% to $31.8 billion and allied lines rose 11.1% to $31.2 billion. The NAIC described 2024 premium growth across the industry as driven largely by rate increases. Those increases are what business owners felt at renewal, and they set the high starting point from which the 2026 declines are now measured.
4. Travelers writes about 9% of commercial package premiums
The CMP market is competitive and fairly fragmented. The ten largest groups held a combined 43.64% share in 2025, leaving more than half of premiums with smaller national, regional, and specialty carriers. The top five groups by CMP direct premiums written were:
- Travelers: 8.94% ($6.26 billion)
- The Hartford: 5.72%
- Chubb: 5.42%
- State Farm: 4.19%
- Tokio Marine: 4.01%
A market this spread out gives business owners real choice when they shop a renewal.
5. Commercial lines account for about half of all P/C premium
Commercial insurance is not a niche corner of the industry. Commercial lines account for about half of U.S. property/casualty premium, with personal lines such as auto and homeowners making up the rest. Property coverage for buildings, equipment, and income is a core piece of that commercial half. When commercial property pricing moves, it moves a significant share of the entire insurance economy with it.
Where commercial property rates are heading
6. U.S. commercial property rates fell 13% in Q2 2026
The pricing cycle has clearly turned. U.S. commercial property rates declined 13% in the second quarter of 2026, according to Marsh’s Global Insurance Market Index, while global property rates fell 12% after 9% declines in each of the two prior quarters. Marsh attributed the drop to abundant capacity, strong insurer profitability, lower reinsurance costs, and higher investment returns. For a business with a clean loss history, this is the strongest negotiating position in years.
7. Global commercial rates have fallen for eight straight quarters
Across all commercial lines, global rates fell 6% in Q2 2026, the eighth consecutive quarterly decline. The U.S. composite rate fell a smaller 2%, while U.S. casualty rates were still rising 7% even as property prices dropped. That split matters for package buyers: the property side of a renewal may come down while the liability side goes up, so the total change can look smaller than the property headline.
8. Eighteen months earlier, property premiums were still climbing
The reversal happened quickly. A Council of Insurance Agents & Brokers survey cited in the NAIC’s 2024 industry report found commercial property premiums still rising 6.0% in the fourth quarter of 2024, down from 7.9% the prior quarter and 11.8% in the fourth quarter of 2023. The surveys measure pricing differently, but the direction is unmistakable: double-digit increases gave way to double-digit decreases in less than three years. Owners whose current terms were set near the peak have good reason to shop.
9. The property loss ratio on package policies fell to 38.8%
Profitability explains why insurers are cutting price. The direct loss ratio on the property portion of CMP fell to 38.8% in 2025, on $46.6 billion of earned premium and $18.1 billion of direct losses, down from 49.9% in 2024 and 66.0% in 2021. Across all property/casualty lines, the industry’s combined ratio improved to 92.9% in 2025, producing a $68.7 billion underwriting gain. Profits that strong attract competition, and competition is what is pushing renewal prices down.

Catastrophe losses that hit commercial property
10. U.S. insured catastrophe losses topped $103 billion in 2025
Natural disasters caused $103.1 billion in U.S. insured losses in 2025 across 84 events, according to Aon data compiled by Triple-I, after $115.6 billion in 2024. These totals include insured losses on homes and businesses alike, plus losses paid by government programs such as the National Flood Insurance Program, so they are not purely commercial. They do show the scale of the loss pool that commercial property premiums help fund, and why insurers price weather risk so carefully.
11. Severe convective storms caused about half of 2025 insured losses
Severe convective storms, the category that covers tornadoes, hail, and straight-line winds, produced $52.3 billion in insured losses from 52 events in 2025. Wildfire, drought, and heat added $43.0 billion and flooding $6.2 billion, while tropical cyclones caused just $188 million in a quiet hurricane year. For businesses across the Plains, Midwest, and South, wind and hail, not hurricanes, were the dominant catastrophe exposure in 2025.
- Severe convective storm 51%
- Wildfire, drought, heat 42%
- Flooding 6%
- Winter weather 1%
- Tropical cyclone 0%
12. A single March 2025 storm outbreak cost insurers $8 billion
Individual storm systems now rival hurricanes. The severe convective storm outbreak of March 14 to 16, 2025, which touched 21 states, caused an estimated $8.0 billion in insured losses, and a second outbreak on May 14 to 16, 2025, added $6.0 billion. Both rank among the five costliest U.S. tornado-related catastrophes on record in Triple-I’s inflation-adjusted table. A business does not need to sit on the coast to face a multimillion-dollar weather claim.
13. The U.S. recorded 5,432 major hail events in 2025
Hailstones one inch or larger were reported in 5,432 events in 2025, up from 5,373 in 2024, based on National Weather Service data compiled by Triple-I. The states with the most major hail events were:
- Texas: 902
- Kansas: 375
- Oklahoma: 369
- Nebraska: 315
- Missouri: 253
Each event is a potential roof, siding, and rooftop equipment claim, which is why hail-prone states carry so much of the severe storm loss described above.
14. NOAA counted 27 billion-dollar disasters in 2024
NOAA’s National Centers for Environmental Information identified 27 weather and climate disasters with at least $1 billion in damage in 2024, costing about $182.7 billion in total and trailing only 2023’s record 28 events. Seventeen of the 27 were severe storms: 11 severe weather and hail events and 6 tornado outbreaks. The five-year annual average for 2020 to 2024 was 23.0 events, compared with 9.0 for 1980 to 2023, a sign that large losses are now routine rather than rare.
15. Hurricanes Helene and Milton caused more than $100 billion in damage
The two costliest U.S. disasters of 2024 were Hurricane Helene, at $79.6 billion, and Hurricane Milton, at $34.3 billion, which together caused more than $100 billion in damage across six states in about two weeks. Helene’s most severe impacts came from historic rainfall and flooding, a peril a property policy may not cover. Triple-I notes that if a property policy does not cover flood, the business income coverage attached to it will not pay for a flood closure either, so coastal and riverside businesses should review flood insurance separately.
Fire losses at commercial buildings
16. Non-residential fires caused $3.6 billion in damage in 2024
Local fire departments responded to an estimated 119,500 non-residential structure fires in 2024, according to the NFPA. Those fires caused 170 civilian deaths, 1,020 injuries, and $3.6 billion in direct property damage, or 20% of all U.S. fire property loss that year. The count rose 1% from 2023. Year after year, fire remains one of the most reliable sources of large commercial property claims.
17. The biggest fire losses of 2024 hit factories and industrial plants
Fire losses are lopsided, and commercial sites drive the extremes. The NFPA reported that the largest losses in 2024 came from fires in a manufacturing facility, industrial plants, and apartment complexes, within a national fire property damage total of $19 billion. For manufacturers and warehouse operators, a single fire can destroy buildings, machinery, inventory, and months of revenue at once. Few other perils can take out an entire operation in a single afternoon.
18. Non-residential building fires rose 19% over ten years
Using fire department reports to the National Fire Incident Reporting System, the U.S. Fire Administration estimated 110,000 non-residential building fires and $3.16 billion in losses in 2023. From 2014 to 2023, the number of these fires rose 19% and inflation-adjusted dollar loss rose 10%. The USFA and NFPA use different methods, so their totals differ, but both point the same way. Commercial fire risk is not shrinking, and the 2022 count of 129,500 fires was the highest in the ten-year series.
19. Carelessness is the leading cause of non-residential fire losses
The most expensive fires are often the most preventable. In 2023, other unintentional and careless fires caused $881.2 million in non-residential building losses, more than electrical malfunctions ($354.4 million) and intentional fires ($349.1 million) combined. Careless fires were the leading cause of dollar loss in 9 of the 10 years from 2014 to 2023. Housekeeping, hot-work permits, and equipment maintenance cost far less than a claim.
The buildings commercial property insurance protects
20. The U.S. has 5.9 million commercial buildings
The Energy Information Administration’s latest published Commercial Buildings Energy Consumption Survey counted 5.9 million commercial buildings with 96.4 billion square feet of floorspace in 2018. From 2003 to 2018, the number of buildings grew 22% while total floorspace grew 35%, so the average building has been getting larger. More square footage per building means a higher replacement cost per policy, which feeds directly into property limits and premiums.
21. Most commercial buildings are small
The typical commercial building is modest. About 71% of commercial buildings were 10,000 square feet or smaller in 2018, and the median building was just 5,400 square feet. At the other end, buildings over 100,000 square feet made up less than 3% of the count but 34% of all floorspace. That split explains the market’s structure: millions of small buildings, plus a small share of very large ones that hold a third of all floorspace.
22. Warehouses, offices, and service buildings lead the count
The most common building types in the EIA survey were:
- Warehouse and storage: 17% of buildings
- Office: 16%
- Service: 15%
- Mercantile (retail): 9%
- Public assembly: 8%
Together, warehouses, offices, and service buildings accounted for 48% of commercial buildings and 42% of floorspace. Each type carries a different fire load, occupancy, and contents value, which is why a carrier rates a warehouse very differently from an office of the same size.
Business interruption and underinsurance
23. Business interruption ranks as the No. 3 global business risk
Lost income after a loss often hurts more than the physical damage. In the Allianz Risk Barometer 2026, business interruption ranked as the No. 3 global risk, cited by 29% of respondents, with natural catastrophes at No. 5. In the same survey, just 3% of respondents rated their supply chains as “very resilient.” A building can be repaired with insurance proceeds, but customers lost during a long closure may not come back.
24. Business income coverage usually starts after 48 to 72 hours
Business income coverage pays lost income and continuing expenses while a damaged property is restored, but it has limits worth knowing. Triple-I notes there is typically a 48 to 72-hour waiting period before coverage begins, and that the standard property policy limits the restoration period to 30 days unless it is extended, up to 360 days, by endorsement. The stakes are real: FEMA and Labor Department data show 40% of small businesses never reopen after a natural disaster, and another 25% close within a year. Most of these terms can be set at purchase, not after a loss.
25. More than 70% of commercial properties may be underinsured by 40% or more
Valuation is the most common hidden gap in a commercial property program. One industry study cited by The Hanover estimates that more than 70% of U.S. commercial properties are at least 40% underinsured, and the insurer notes other studies suggest the problem is even greater. Limits set years ago rarely keep pace with construction costs, and an underinsured building can leave the owner covering a large share of a total loss. The Hanover also describes re-establishing property replacement costs on a five- to seven-year cycle as the basis of good underwriting practice.
How to buy commercial property coverage that fits
The data points to a short, practical checklist. Rates are softening, but storms, fire, and valuation gaps still decide whether a policy actually pays enough after a loss:
- Get the building value right first. With more than 70% of properties estimated to be badly underinsured, an updated replacement cost appraisal is the highest-value step before any renewal.
- Use the soft market. With U.S. property rates down 13% in Q2 2026, compare carriers on our carrier comparison page and request quotes rather than accepting a flat renewal.
- Consider a package for a small business. Small firms can often bundle property, liability, and business income into a business owners policy instead of buying separate contracts.
- Check the income coverage terms. Confirm the waiting period and the restoration period, since the standard 30-day limit can be extended by endorsement.
- Close the flood gap. If you are near the coast or a river, review flood coverage separately, since many commercial property policies exclude it.
- Know where the numbers come from. Our methodology page explains how we source and verify every figure.
Frequently Asked Questions
Are commercial property insurance rates going down in 2026?
Yes, for most buyers. U.S. commercial property rates fell 13% in the second quarter of 2026, and global commercial rates have now declined for eight straight quarters. Strong insurer results, including a 38.8% direct loss ratio on the property side of package policies in 2025, are fueling the competition behind those cuts. Individual results still depend on each property’s loss history, construction, and location.
What causes the most commercial property losses?
Severe weather and fire. Severe convective storms caused $52.3 billion in U.S. insured losses in 2025, about half of all catastrophe losses that year. Non-residential structure fires added $3.6 billion in direct property damage in 2024, with the largest losses at manufacturing and industrial sites.
How common is underinsurance on commercial buildings?
Very common. An industry study cited by The Hanover estimates that more than 70% of U.S. commercial properties are underinsured by at least 40%. The usual cause is a building limit set years ago that has not been updated for current construction costs, which is why periodic appraisals matter.
Does commercial property insurance cover lost income?
It can, through business income (interruption) coverage, which is often added to a property policy or included in a package. Coverage typically starts after a 48 to 72-hour waiting period, and the standard restoration period can be extended by endorsement. Given that FEMA data show 40% of small businesses do not reopen after a disaster, income coverage is often as important as the building limit.
How big is the commercial property insurance market?
Commercial multiple peril policies generated $70.1 billion in direct premiums written in 2025, and the fire and allied lines added more than $63 billion more. You can see how coverage and pricing vary where you operate on our commercial property insurance page.
