Contractors Insurance in Washington

Washington requirements

Washington contractor registration requires a $30,000 bond for general contractors ($15,000 for specialty) and $200,000 public liability plus $50,000 property damage, or $250,000 combined.

To check an insurer’s or agent’s license, contact the Washington State Office of the Insurance Commissioner.

General liability insurance

Commercial general liability (CGL) insurance covers claims that your business caused bodily injury or property damage to others (Coverage A), personal and advertising injury such as libel, slander, or copyright infringement (Coverage B), and no-fault medical payments for non-employees (Coverage C), according to the Insurance Information Institute. It pays defense costs and damages up to the policy limits.

CGL policies exclude workers’ compensation, employment practices, most pollution, and liquor liability, and professional liability may also be excluded. You can buy CGL on its own, in a business owner’s policy, or in a commercial package policy.

Liability limits

General liability limits are usually stated as a per-occurrence limit, the most the policy pays for one claim, and an aggregate limit, the most it pays in a policy period. Contracts and licenses often set minimums: Georgia, for example, requires $300,000 or $500,000 per occurrence depending on the contractor license, and New Jersey home improvement contractors need at least $500,000 per occurrence. Higher limits cost more, and an umbrella policy can add limits above your general liability, auto, and employers’ liability coverage.

License bonds vs. insurance

A contractor license bond isn’t insurance for your business. It’s a guarantee, purchased from a surety company, that you’ll follow licensing law and contracts; if the surety pays a claim, you’re generally expected to repay it. States such as Arizona, California, Iowa, South Carolina, and Washington require bonds for some licenses, while others rely on liability insurance or net worth requirements instead.

Who must carry workers’ comp in Washington

Washington doesn’t allow private workers’ compensation coverage; employers must buy it through the Department of Labor & Industries or be certified to self-insure.

The state agency is the Washington State Department of Labor & Industries. Check the agency’s rules for how part-time workers, owners, officers, and family members count, and whether independent contractors could be treated as employees.

Business vehicles

If a vehicle is used primarily for business, there’s likely no coverage under a personal auto policy, the Insurance Information Institute says. Company-owned vehicles generally need commercial auto coverage, and hired and non-owned auto coverage handles employees driving their own cars for work. Insurers often recommend a $1 million liability limit, with $500,000 as a minimum.

Certificates of insurance

Clients, landlords, and general contractors often ask for a certificate of insurance (COI) showing your coverage and limits, and sometimes ask to be added as an additional insured. Many insurers issue COIs online; ERGO NEXT, for example, says it offers unlimited certificates at no extra cost. Check contract requirements before you buy so your limits match.

How to compare quotes

1. List your risks. Customers on site, work at client locations, vehicles, employees, advice you give, and equipment.
2. Check what’s required. State workers’ comp rules, licensing boards, leases, and client contracts.
3. Choose coverages. General liability or a BOP, plus workers’ comp, commercial auto, and professional liability as needed.
4. Compare quotes on the same limits. Use the same per-occurrence and aggregate limits and deductibles.
5. Review service. Certificates, claims, and payment options.

Example online carrier: ERGO NEXT

ERGO NEXT Insurance, formerly NEXT Insurance, has been wholly owned by Munich Re’s ERGO since July 1, 2025, after a deal that valued NEXT at $2.6 billion, and adopted the ERGO NEXT name on January 15, 2026. The company says it serves more than 750,000 small businesses and sells online, with quotes in about 10 minutes and coverage that can start the next day, as well as through agents.

Its products include general liability, business owner’s policies, workers’ compensation, and professional liability, with commercial property, commercial auto, tools and equipment, and other coverages listed on its site; agents can’t sell its commercial auto. Its workers’ compensation page lists 41 states and Washington, D.C., and doesn’t include Indiana, Nebraska, North Dakota, Ohio, Rhode Island, Vermont, Washington, West Virginia, or Wyoming.

Professional liability

Professional liability, or errors and omissions (E&O) insurance, is for businesses that give advice, make recommendations, design, provide care, or represent others. It pays judgments and defense costs, even when you did nothing wrong, according to the Insurance Information Institute.

How workers’ comp works

Workers’ compensation pays medical bills and lost wages for employees hurt on the job and, in most states, protects the employer from most employee lawsuits over those injuries. Every state sets its own rules for who must carry it; some require coverage from the first employee, others at three, four, or five, and Texas lets most private employers opt out. Ohio and Washington require employers to buy through a state fund or self-insure.

Short-term and on-demand coverage

Thimble sells business owner’s policies, general liability, commercial property, workers’ compensation, professional liability, equipment coverage, cyber, and event liability, but not commercial auto. It’s a producer rather than an insurer, and coverage can be bought by the hour, day, month, event, or year, according to NerdWallet and Thimble’s broker materials.

Home-based businesses

If you run a business from home, a typical homeowners policy gives only about $2,500 of coverage for business equipment, according to the Insurance Information Institute, and often excludes business liability. A home-based business endorsement, an in-home business policy, or a BOP can fill the gap.

Small businesses by the numbers

The SBA Office of Advocacy counts 36,207,130 small businesses in the U.S., 99.9% of all businesses, employing 62.3 million people, or 45.9% of private-sector workers.

Who needs business liability coverage

• Customer-facing businesses where visitors can be hurt.
• Service businesses that work at clients’ locations.
• Businesses that advertise, because of advertising injury claims.
• Businesses with contracts or leases requiring proof of coverage.
• Professionals who give advice, who also need professional liability.

Checking a plan and insurer

• Contract requirements. Match limits and additional-insured wording to your contracts and licenses.
• Exclusions. Read what the policy doesn’t cover, such as professional services or autos.
• Workers’ comp rules. Confirm your state’s requirement for your headcount and industry.
• Insurer license. Check the insurer with your state insurance department.
• Certificates. Ask how quickly you can get COIs.

What an independent agency does

An independent insurance agency is licensed to sell policies from several insurance companies. Instead of quoting one company's products, an independent agent can compare options from the insurers the agency represents, explain the differences in coverage, and help you re-shop at renewal. The insurance company, not the agent, makes underwriting and claim decisions.

Blake Insurance Group is an independent agency. We work with clients by phone, email, and online in states where we are licensed, and we will tell you which insurers we can quote for your situation.

How to verify an insurer or agency

Before buying through any website or app, confirm who is selling you the policy and who will issue it:

1. Find the licensed agency or insurer named in the site's footer, terms, or license page.
2. Look up the agency or producer on your state insurance department's license search, or through the National Insurance Producer Registry (NIPR).
3. Look up the insurer on your state insurance department's company search to confirm it is authorized in your state.
4. Save the insurer's name and policy number once issued, since that is who handles claims.

A legitimate service will make this information easy to find. Be cautious if you cannot identify the licensed entity.
