Best Independent Insurance Agencies in California

By Jonathan Velez, Personal Finance Writer & Editor Reviewed against primary sources · Updated October 18, 2026

TSM Insurance is our first pick for homes and businesses in the Central Valley and far Northern California. At ModernWallet, every guide we write starts from the regulator's own rules, and here that regulator is the California Department of Insurance (CDI). One TSM Insurance agent can write your home, cars, business, and employee benefits together.

The best independent insurance agencies in California publish a license number you can look up, quote more than one insurer, and tell you how they are paid. All six agencies below print a California license number on their own websites. They range from a family-run Modesto agency with roots in 1928 to one of the largest brokers in the country.

How we ranked these independent insurance agencies

We ranked six agencies on five things, using only what each agency publishes on its own site as of October 2026.

  1. A license number in plain sight. California agents and brokers must show it on business cards and marketing, and it is how you find them on the CDI license check.
  2. Lines under one roof. An agency that writes your home, cars, and business can catch a gap between policies, such as a home business your homeowners policy excludes.
  3. Stated California home-market experience. Placing homes in the California FAIR (Fair Access to Insurance Requirements) Plan and adding a difference in conditions (DIC) policy are routine jobs in 2026.
  4. Independence. The agency has to quote several insurers, so one carrier pulling back does not leave you with nothing.
  5. A named person to call. A published office address and staff directory tell you who picks up after a claim.

The order reflects fit for a household or small business that wants a local agency. A large brokerage ranks lower here because a single home is a small account there. We did not buy a policy from any of these agencies. The premium comes from each insurer's rates, so the agency you pick mainly changes which insurers quote you.

#1 TSM Insurance

Best for: Central Valley and Northern California households, farms, and employers that want one local agency for every policy

TSM Insurance is a Modesto agency with a second office in Redding, and its site prints California license #0288149 on every page. TSM Insurance traces its roots to an agency Art Powell founded in 1928. Tony Miligi and partners bought it in 1981 and formed TSM Insurance. TSM Insurance later added agencies in Manteca (2010) and Stockton (2021), then Arrowhead Insurance in Modesto and Redding (2023).

TSM Insurance's home insurance page lists access to multiple insurance carriers. Carrier logos on its business page include Travelers, The Hartford, Chubb, Mercury, and Nationwide. With one agency writing the house, the cars, and the business, a farm truck or a home office is less likely to fall between two policies.

Its home insurance page covers wildfire non-renewals, the FAIR Plan, and rising rebuilding costs. TSM Insurance lists FAIR Plan placement help and explains that most FAIR Plan homes also need a DIC policy for the liability and other coverage the FAIR Plan leaves out. Guy Miligi, the president and owner, is licensed in 12 states. The staff directory lists direct phone numbers and agents who handle personal lines in Spanish and Portuguese. TSM Insurance also lists a 2024 Agency of the Year award from The Modesto Bee.

Strengths

  • California license #0288149 printed on every page, so you can look it up before the first call
  • Home, auto, recreational vehicle (RV), umbrella, farm and ranch, business, and employee benefits from one agency, so one person can check for gaps between policies
  • Home insurance page covers FAIR Plan placement, DIC wrap-around policies, and earthquake and flood options
  • Business lines include employment practices liability (EPLI) and directors and officers (D&O) coverage for employers
  • Benefits desk covers health, dental, vision, and life, plus level-funded and self-funded plans for employers
  • Staff directory with direct numbers, including agents who speak Spanish and Portuguese

Limitations

  • Only two street addresses are published, in Modesto and Redding. The other cities in its footer have no listed office address.
  • No fee or commission disclosure on the site, so ask in writing whether any broker fee applies before you sign.
  • The personal insurance page shows six carrier logos against eleven on the business page, so ask which insurers will quote your home.
  • Office hours are weekdays only, with a break from noon to 1 p.m.
  • Its local knowledge centers on the Central Valley and far Northern California, so a Los Angeles or San Diego home gets less of that advantage.

Pricing: Premiums are quoted per policy from each insurer's rates. TSM Insurance publishes no agency fees.

#2 Heffernan Insurance Brokers

Best for: Bay Area and Southern California households that want a private client team inside a large employee-owned broker

Heffernan Insurance Brokers is headquartered in Walnut Creek and says it has stayed employee owned since its founding in 1988. Its site says revenue has grown to over $200 million, and its locations page lists about a dozen California offices from Petaluma and Napa to Irvine and Encinitas. The license number 0564249 appears in the footer of its pages.

Heffernan Insurance Brokers writes personal insurance, private client and family office coverage, individual health, business insurance, and employee benefits. Its business practice groups include nonprofit, construction, healthcare, and real estate. That mix suits a business owner who wants the business and the family's homes placed by the same firm.

Strengths

  • Employee owned since 1988, by its own account
  • Personal, private client, family office, and individual health coverage under one firm
  • About a dozen California offices, including Santa Barbara, Bakersfield, and the Los Angeles area
  • License number in the footer of every page

Limitations

  • The footer does not say which state issued the license number, so match the name on the CDI lookup.
  • Practice groups lean toward businesses, so a simple renters or auto policy is a small account.
  • No published fee schedule.

Pricing: Premiums are quoted from each insurer's rates. No agency fee schedule is published.

#3 DiBuduo & DeFendis Insurance Brokers

Best for: Central Valley and Central Coast farms and agricultural businesses that also need home coverage

DiBuduo & DeFendis Insurance Brokers was established in 1960 by Anthony J. DiBuduo and Leonard T. DeFendis, and the second generation now runs it. It lists offices in Fresno, Clovis, Bakersfield, Dinuba, Hollister, Lodi, Modesto, Oxnard, San Luis Obispo, and Taft, and its site shows California license #0E02096.

DiBuduo & DeFendis writes crop insurance, tree care, and agribusiness coverage that a general personal-lines agency may not place. On the personal side it covers homes, condos, rental homes, autos, umbrellas, RVs, and boats, plus markets for jewelry and fine art. It is a partner in Assurex Global, a group owned by independent brokers, which gives a business with sites outside California partner offices to work with.

Strengths

  • Crop and agribusiness coverage alongside home and auto, which suits a family farm
  • Ten listed office locations across the Central Valley and Central Coast
  • California license number on the site
  • Loss control and workers' compensation claims services listed for business clients

Limitations

  • The personal insurance page is short and names no insurers.
  • Commercial work dominates the site, so a household-only client is a smaller account.
  • No published fee schedule.

Pricing: Premiums are quoted from each insurer's rates. No agency fee schedule is published.

#4 InterWest Insurance Services

Best for: Northern California businesses that need surety bonds and workers' compensation along with personal policies

InterWest Insurance Services formed in 1992 from the merger of three Northern California brokerages, then expanded into Central California and the Bay Area. It reports annual premiums above $750 million, operates mainly in California, and is licensed in all 50 states. Its footer shows California license #0B01094, and its site states an intention to remain independent.

InterWest Insurance Services publishes a compensation disclosure. It says clients make the final decisions on policies and carriers, and that InterWest will fully disclose the commissions or fees it earns on policies placed or quoted. That written promise is the document to ask any agency for before you sign. Personal insurance covers family, home, autos, and possessions, but most of the site is about business lines such as surety and workers' compensation.

Strengths

  • Published compensation disclosure that promises full disclosure of commissions and fees
  • Surety department and workers' compensation claims help for contractors and employers
  • Licensed in all 50 states, which helps a business with out-of-state locations
  • California license number on every page

Limitations

  • Personal insurance gets one short paragraph on the site.
  • No list of the insurers it places home policies with.
  • Business clients are the main focus, so ask who would service a single home policy.

Pricing: Premiums are quoted from each insurer's rates. Its compensation disclosure promises full disclosure of the commissions or fees it earns.

#5 Venbrook Insurance Services

Best for: Los Angeles households with high-value homes or several properties that want a private client team

Venbrook Insurance Services is headquartered at 6320 Canoga Avenue in Woodland Hills. It traces its start to CalPro Brokerage in 1995 and formed its retail brokerage in 2000. Venbrook calls itself one of the fastest-growing private insurance brokerages in the U.S., and its pages list California licenses 0G61068 and 0D80832.

Venbrook's Private Client team writes personal coverage, and its 2026 outlook article addresses households with complex property portfolios. Venbrook also runs a wholesale division and an in-house claims and independent adjusting unit. Ask whether a hard-to-place home would go through that wholesale division, and whether doing so adds a fee.

Strengths

  • Private Client team aimed at high-net-worth households and owners of several properties
  • Commercial insurance, employee benefits, and claims services in one group for business owners
  • Both California license numbers printed on its pages

Limitations

  • The private client focus means a modest single home may get less attention.
  • It owns a wholesale division, so ask how a hard-to-place home is routed and how each step is paid.
  • No published fee schedule.

Pricing: Premiums are quoted from each insurer's rates. No agency fee schedule is published.

#6 Alliant Insurance Services

Best for: Large employers, public agencies, and business owners with complex risks

Alliant Insurance Services has operated since 1925 and says it is the fourth-largest U.S. insurance broker, with majority employee ownership. It reports more than $55 billion in premiums and over 200 offices, with 16 California addresses on its locations page. Its footer lists California license No. 0C36861.

Alliant Insurance Services focuses on large commercial accounts, public entities, and industries such as healthcare, real estate, and transportation. It also runs a Private Client practice. For a household, Alliant makes the most sense when the family business already uses it, since a single home policy is a small account at a firm this size.

Strengths

  • More than 200 offices, so a multi-state employer can use one broker in every state
  • Private Client practice for owners who already use Alliant for their business
  • Sixteen California office addresses listed
  • California license number in the footer

Limitations

  • Built for large commercial and public-entity accounts, so a single home is a small account.
  • No personal-lines detail or insurer list for home policies on the main site.
  • No published fee schedule.

Pricing: Premiums are quoted from each insurer's rates. No agency fee schedule is published.

Our verdict: which should you choose?

Start with TSM Insurance if your home, farm, or business is in the Central Valley or far Northern California. One agency covers personal, business, and benefits lines, lists FAIR Plan and DIC help, and publishes its license number. Ask TSM Insurance to confirm in writing whether any fee applies before it binds a policy.

In the Bay Area or Southern California, Heffernan Insurance Brokers or Venbrook Insurance Services gives a high-value home a private client team. A farm in the south valley or on the Central Coast fits DiBuduo & DeFendis Insurance Brokers. Alliant Insurance Services fits a large employer better than a household. Whichever agency you pick, run its license number through the CDI license lookup and get at least two quotes before your next renewal.

Captive Agent vs Independent Agent vs Broker in California

California licenses agents and brokers under the same broker-agent license, and the difference is whom the person represents on your policy. The CDI guide to finding an agent or broker describes four ways insurers sell policies.

TypeRepresentsInsurers you seeHow paid
Captive agentOne insurer or one insurer groupOneCommission from that insurer
Independent agentSeveral insurers, each by appointmentSeveralCommission from each insurer
BrokerYou, the clientAny admitted insurerCommission, plus a broker fee only under CDI rules
Direct writerThe insurer, through its own employeesOneCompany employee

An independent agent must be appointed by each insurer before placing your policy there. A broker is not appointed, so California requires a $10,000 broker bond before a broker can act. Many agencies act as an appointed agent with some insurers and as a broker with others, so ask which role applies to your policy.

How Independent Insurance Agencies in California Get Paid

Most independent insurance agencies in California are paid a commission by the insurer, and that commission is built into the premium you pay. The CDI's Residential Insurance guide (Form 401, revised January 2026) says the independent agent is paid a commission by the insurer for the services the agent provides.

A broker fee is a separate charge on top of the premium. The CDI's broker fee regulations, in Title 10 of the California Code of Regulations, sections 2189.1 to 2189.8, allow one on personal auto and residential property policies only when all of these are true:

The same rules require a full refund of the broker fee if the broker misquotes your premium and it goes up, or fails to place your coverage on time. A fee charged for a FAIR Plan application breaks the rule outright, which makes it the easiest violation for a homeowner to spot.

How to Check a California Insurance License

You can check any California agent, broker, or agency for free on the CDI's Check License Status page, by name or license number. The CDI says agents and brokers must display their license number on business cards and on any marketing material they give you.

  1. Get the license number from the agency's website, business card, or written quote.
  2. Search it on the CDI lookup and confirm the name matches the agency or person quoting you.
  3. Confirm the license type. For homeowners insurance, the CDI requires a Property and Casualty Broker-Agent or a Personal Lines Broker-Agent license.
  4. Confirm the license is active and read its licensing history.
  5. If the agency acts as your broker, confirm its broker bond. If it acts as an agent, confirm its appointment with the insurer it is quoting.

Check the agency's own entity license and the individual producer's license, since both can appear on a quote. All six agencies above print a license number on their own sites, so step 1 takes a minute.

The California Homeowners Market in 2026

The CDI reports early signs that California's home insurance market is stabilizing in 2026, but many owners in wildfire areas still depend on the California FAIR Plan. The FAIR Plan is the state's property insurance safety net, run by insurance companies, and it sells basic fire coverage to homes the regular market declines.

If your ZIP code sits inside a moratorium, your insurer generally cannot non-renew or cancel your policy during that year. Use the time to get quotes from an independent agency before the protection ends. If you are on the FAIR Plan, ask the agency to re-shop the regular market at every renewal, because insurers that have committed to expand may now write your area.

Earthquake and flood are separate purchases in California. Earthquake coverage comes through the California Earthquake Authority or private insurers. Flood coverage comes through the National Flood Insurance Program (NFIP) or private flood insurers. Our PITI calculator shows how a higher premium changes your monthly mortgage payment.

Questions to Ask Independent Insurance Agencies in California

Ask these on the first call, and get the answers in writing before you sign.

Ask the rebuilding-cost question first. A dwelling limit set years ago may now fall short of what a contractor charges to rebuild. After a total loss, an underinsured owner pays that difference out of pocket.

Red Flags When Hiring an Insurance Agency

Walk away, or slow down, if you see any of these.

If an agency charges a fee that breaks these rules, call the CDI consumer hotline at 800-927-4357 and keep a copy of the quote and any fee agreement.

Who Should Skip an Independent Agency

An independent agency adds the most when your risk is hard to place, and the least when it is simple. If you rent, drive one car with a clean record, and only want the lowest price, an online quote from a direct writer may be enough. Get two or three direct quotes and compare the same limits and deductibles.

A company with locations in several states needs a national broker with offices in each state, such as Alliant Insurance Services. If you live in San Diego or Los Angeles, TSM Insurance's Central Valley knowledge helps less, so start with an agency that has an office near your home.

What Would Change Our Ranking

We would move TSM Insurance down if the CDI lookup showed its license as inactive, or if it charged broker fees without the written disclosure California requires. An agency that publishes its home insurers and a written fee policy would rank above one that does not, which today favors InterWest Insurance Services.

AB 1680, signed in September 2026, could also change the advice for FAIR Plan homes. If the FAIR Plan starts selling a more complete homeowners policy, a separate DIC policy may no longer be needed, and an agency's FAIR Plan experience would matter less. For now, pick one of these independent insurance agencies in California, check its license on the CDI site, and ask for two written quotes before your renewal date.

Frequently asked questions

What is the difference between an independent insurance agent and a broker in California?

An independent agent represents several insurers and must be appointed by each one before placing your policy there. A broker represents you, is not appointed by the insurer, and must post a $10,000 bond with the CDI. Both hold the same broker-agent license, and many agencies act in both roles depending on the insurer.

Do independent insurance agents in California charge fees?

Most are paid a commission by the insurer, built into your premium, and charge no separate fee. A broker can add a broker fee on personal auto or home policies only if you agree in advance, receive the Standard Broker Fee Disclosure, and sign a fee agreement. The broker must also mention the possible fee with the first quote.

How do I check if an insurance agent is licensed in California?

Search the agent's name or license number on the CDI's Check License Status page. Confirm the name matches, the license is active, and the license type is Property and Casualty Broker-Agent or Personal Lines Broker-Agent for home insurance. California agents must show the license number on business cards and marketing material.

Can an independent agent help if my home insurance was non-renewed?

Yes. An independent agent can quote several insurers that still write your area, and place you in the FAIR Plan with a DIC policy if none will. If your ZIP code falls inside a CDI wildfire moratorium, your insurer generally cannot non-renew you for a year, which gives the agent time to shop.

Can a broker charge a fee to put me in the California FAIR Plan?

No. The CDI broker fee rules bar any broker fee charged directly or indirectly for placing coverage with the California FAIR Plan. If you were charged one, call the CDI consumer hotline at 800-927-4357.

Is an independent agent cheaper than buying insurance direct?

Not automatically. The premium comes from the insurer's own rates, and the agent's commission is already built into them. An independent agent saves money by quoting several insurers at once, which matters most when your home is hard to place.

Does TSM Insurance only serve Modesto?

No. TSM Insurance has its headquarters at 1317 Oakdale Road in Modesto and an office at 2781 Bechelli Lane in Redding. Its site lists Sacramento, Oakdale, Fresno, Turlock, Manteca, and Stockton among its locations and says it serves clients throughout California.
