Regional home insurers: why they're worth a quote
Regional home insurers write in a few states, often through independent agents. Where they rank, what they offer, the trade-offs and how to vet one.
A regional home insurer is a company that writes homeowners policies in one region or a limited set of states rather than nationwide, and it usually sells through independent agents. In many states these companies hold top-10 market positions, price a house with their own rating plans and often offer coverage options the national brands do not. A quote from one costs nothing, but you should weigh their concentration in one weather zone, their uneven financial strength ratings and the fact that some of them have been pulling back from home insurance.
What counts as a regional insurer
There is no official definition. Our profiles use the label "Regional carriers" for 32 of the 100 largest homeowners groups in the NAIC's 2025 data. Together they wrote $22.37 billion of homeowners premium, 11.84% of the national market, according to our arithmetic in The 100 largest homeowners insurance companies in the U.S., 2025. The label covers a wide range:
- Midwestern mutuals and mutual holding companies such as Auto-Owners Insurance (26 states, more than 6,300 agencies), Acuity, West Bend and Westfield.
- Mid-Atlantic and Northeast companies such as Erie Insurance, The Hanover, NJM, NYCM, Mapfre and Arbella.
- Single-state or two-state specialists such as PEMCO (Washington and Oregon) and NYCM (New York only).
- Publicly traded regionals such as Selective, Kingstone and Mercury, and group-affiliated regionals like Donegal.
They also differ in who owns them. Many are policyholder-owned mutuals or mutual holding companies. Erie is a reciprocal exchange run by a public company as attorney-in-fact. Others are ordinary stock companies. Our mutual, stock and reciprocal insurers: who owns your insurer guide explains why that affects dividends and governance far less than it affects how you read an annual report.
Most sell through independent agents, who place business with several companies. Not all do: Shelter uses exclusive agents, and NJM and PEMCO sell largely direct. See captive agents, independent agents and direct insurers for how those channels differ.
Where regional insurers carry real weight
National brands are the largest in most state tables, but the rest of the top 10 is often regional. These 2025 shares come from the NAIC's state market data on this site (share of each state's homeowners premium):
| State | Regional insurers in the top 10 | 2025 share |
|---|---|---|
| Massachusetts | Mapfre #1, Safety #3, Andover #4, Arbella #6, Plymouth Rock #8 | 9.93%, 7.25%, 6.85%, 5.47%, 4.23% |
| Ohio | Erie #3, Grange #6, Cincinnati #8, Auto-Owners #10 | 7.63%, 4.66%, 4.21%, 3.94% |
| Wisconsin | Auto-Owners #3, Erie #4, Acuity #6, West Bend #9 | 6.17%, 5.92%, 4.87%, 3.11% |
| Pennsylvania | Erie #2 | 16.71% |
| Michigan | Auto-Owners #2, The Hanover #4, Farm Bureau Insurance of Michigan #6 | 17.12%, 7.46%, 5.41% |
| Nebraska | Farmers Mutual of Nebraska #4 | 9.30% |
| New York | NYCM #6 | 3.85% |
| Washington | PEMCO #8, Mutual of Enumclaw #9 | 4.69%, 2.28% |
Farm Bureau companies also lead in some states (Tennessee Farm Bureau was second in Tennessee with 17.85%). They have their own category on this site; see Farm Bureau home insurance: how membership works.
A company with a 17% share in a state did not get there by accident. Agents there know it, its adjusters work the same hail and ice-storm seasons you do, and it has years of claims experience in your counties. That does not make it cheaper or better for your house, but it does make it a serious option.
Why a regional quote is worth the time
Insurers price the same house differently. Each company files its own rates and rating plan with the state and weighs roof age, claims history, home age, construction and territory its own way. how insurers file rate increases with regulators covers the mechanics. A house that one company surcharges for a 17-year-old roof may fit another company's underwriting guidelines without a penalty. We know of no source that shows regional carriers as a group are cheaper or dearer than national ones, so treat any blanket claim in either direction with suspicion and compare real quotes.
Their policy forms can differ in ways that matter after a loss. From the company profiles on this site, as examples (all subject to state, form and endorsement):
- Erie's base policy offers 100% guaranteed replacement cost on the dwelling where available, with conditions for reporting home improvements.
- Acuity sells a matching-siding endorsement with limits of $10,000 to $40,000, plus guaranteed home replacement and limited inland flood coverage.
- Mapfre's Massachusetts page lists extended replacement cost up to 150% of the dwelling limit.
- Selective offers an endorsement that replaces undamaged roofing or siding after a covered loss (not yet available in New Jersey).
Those options address the most common sources of claim disputes: a dwelling limit that falls short, siding that cannot be matched and partial roof replacement. See extended and guaranteed replacement cost coverage and matching: when new shingles or siding don't match. Whether a given company covers the same thing on your policy is a question for the agent and the policy form, not for a ranking.
Service evidence is mixed, as everywhere. Erie placed second among homeowners insurers in J.D. Power's 2026 U.S. Home Insurance Study (678 points), after Amica and ahead of Chubb. Most other regional carriers are not named in J.D. Power's published top three, and Donegal is not ranked at all.

The trade-offs
Concentration in one weather zone
A national insurer spreads hail in Texas against hurricanes in Florida and wildfires in California. A regional one often holds most of its homeowners premium in a single exposure. About 72% of Mapfre's homeowners premium comes from Massachusetts, according to its profile; Kingstone writes 98% of its premium in New York; Missouri and Arkansas together account for about 45% of Shelter's. A hailstorm season in the Midwest hits every policy at once.
The financial results show it. Wisconsin regulators reported that Acuity, which writes mostly commercial insurance, lost $153.7 million on underwriting in 2022 and $144.0 million in 2023 across all lines, before narrowing the loss to $6.8 million in 2024 after rate increases. Selective's personal lines combined ratio was 121.7% in 2023 and 109.3% in 2024, according to its profile. Regional carriers absorb bad years with reinsurance and surplus, and what you see on the outside is rate increases and tighter rules about who they will insure.
Retrenchment and closed doors
That correction can reach you as a nonrenewal or a refusal to quote. Recent examples from the profiles:
- Berkshire Hathaway GUARD's AmGUARD stopped taking new homeowners submissions nationwide on July 8, 2024 and is nonrenewing existing policies state by state.
- Acuity told Wisconsin regulators in August 2025 that it would withdraw from personal lines in Nevada after nearly a decade of unprofitable results.
- Donegal limited new personal lines business and nonrenewed part of its book, including a legacy Maryland book; its homeowners premium fell 12.5% in 2025.
- Selective's new business premium fell 37% in 2025 as it narrowed its target market to higher-value homes, and renewal prices rose 18.6% on average, according to its profile.
- Mapfre left New York, New Jersey, Kentucky, Tennessee and Indiana in 2017 and 2018 to concentrate on 11 core states.
If a regional company is "not writing new business" in your county, an agent will tell you quickly; if you hold a policy with one, read your home insurance was nonrenewed: what to do now before you need it.
Uneven financial strength
Regional ratings run from the top to the bottom of the range, so a company's presence in your state's top 10 does not tell you its rating. From the profiles: Acuity and Auto-Owners carry AM Best A+ (Superior), Erie and The Hanover A (Excellent), Stillwater B++ (Good) after AM Best's April 2025 downgrade, and One Alliance North America B (Fair) with a negative outlook in March 2026. Check the legal insurer, not the brand, and the date. Financial strength ratings: AM Best, S&P, Moody's and Demotech shows how.
Ownership changes
Regionals consolidate. Mapfre agreed on July 23, 2026 to buy Safety Insurance Group for $1.54 billion, which would combine Massachusetts' first- and third-largest home insurers if it closes, as expected, in the first quarter of 2027. Andover reorganized into a mutual holding company on January 1, 2026. Neither changes your policy overnight, but ask how an acquisition would affect your agent, your forms and your renewal.
How to find and vet the regional options in your state
- Start with the state market table. The the largest home insurers in every state, 2025 guide and the state's page on this site list the top 10 groups. Look for names you did not expect.
- Ask an independent agent which regionals they hold appointments with, and which are taking new homes right now. A good agent knows which companies are open to a 20-year-old roof or a prior water claim.
- Check your state insurance department. Most publish a list of licensed insurers and complaint data; use the home insurance rules by state for the right department.
- Confirm the legal entity and its rating. The company on the declarations page can be a pooled affiliate with a different name than the brand.
- Compare like with like. Same dwelling limit, same deductibles (including any separate wind or hail deductible), same roof settlement basis. Use the how to compare homeowners insurance quotes guide and the compare home insurers side by side tool.
Say you live in Ohio and your renewal arrives with a large increase. A hypothetical comparison could include your current national carrier plus a quote from Erie, Grange or Auto-Owners through an independent agent. Before choosing the cheapest, line up the roof payment basis, whether the dwelling is covered at replacement cost with or without a cap, and any separate wind or hail deductible. A lower premium with a roof paid at actual cash value is not the same product.
Key takeaways
- "Regional" is a descriptive label, not a regulatory one: 32 of the NAIC's 100 largest homeowners groups fit our version, with 11.84% of 2025 premium.
- In states such as Massachusetts, Ohio, Wisconsin and Pennsylvania, regional insurers hold several top-10 spots, and a second or third quote from one is cheap to get.
- Their forms can differ meaningfully, including guaranteed replacement cost, matching siding and roof replacement endorsements, so compare coverage, not just price.
- The trade-offs are concentration in one weather zone, uneven ratings from A+ to B (Fair), agent-only access and a pattern of tightening or exiting in recent years.
- Verify the legal insurer, its current rating and whether it is accepting new business at your address before you decide.
