Washington State Contractor Licensing and Insurance Checklist

Getting your Washington State contractor registration is not a single-step process. The Department of Labor & Industries (L&I) requires you to satisfy multiple prerequisites before you can legally perform construction work in the state, and each one depends on having the previous pieces in place. Miss a step or get the order wrong and you could face weeks of delays, rejected applications, or worse, fines for operating without proper registration.

This checklist walks through every requirement from business formation to final approval. Whether you are starting a brand-new contracting business or transitioning from working as an employee to running your own operation, use this guide to make sure nothing falls through the cracks.

Your Washington Contractor Registration Checklist

Before diving into the details, here is the high-level sequence you need to follow. Each step is covered in full below.

1. Form your business entity (sole proprietorship, LLC, or corporation) 2. Obtain your UBI number from the Washington Secretary of State 3. Secure a contractor's bond ($12,000 for most specialties) 4. Register for L&I industrial insurance (workers' compensation) 5. Obtain general liability insurance (practically required for real-world work) 6. Submit your L&I contractor registration application 7. Pay the registration fee and wait for approval

Keep this list handy. It is the roadmap for everything that follows.

Step 1: Form Your Business Entity

The first decision you need to make is how your contracting business will be structured. Washington allows contractors to operate as a sole proprietorship, a limited liability company (LLC), or a corporation. Each structure has different implications for personal liability, taxes, and administrative requirements.

Sole Proprietorship is the simplest option. There is no formal filing required to create one. You simply begin operating under your own name. However, if you want to use a business name other than your legal name, you must file a trade name registration with the Washington Secretary of State. Sole proprietorships offer no separation between personal and business liability, which is an important consideration in the construction industry where lawsuits are common.

Limited Liability Company (LLC) is the most popular choice for new contractors. An LLC separates your personal assets from business liabilities, meaning a lawsuit against your company does not automatically put your home and personal savings at risk. You form an LLC by filing Articles of Organization with the Washington Secretary of State. The current filing fee is $200.

Corporation is less common for small contractors but may make sense for larger operations or those seeking outside investment. Corporations require Articles of Incorporation, bylaws, and more formal recordkeeping.

Regardless of your entity type, you will need an Employer Identification Number (EIN) from the IRS. You can apply for an EIN online at no cost through the IRS website. Even sole proprietors without employees benefit from having an EIN because it allows you to keep your Social Security number off business documents.

Once your entity is formed, register for a Washington State Business License, which also provides your Unified Business Identifier (UBI) number. The UBI number is required for your contractor registration application and for tax filing. You can register through the Washington Department of Revenue's Business Licensing Service. This step also enrolls you in the state's tax system, so be prepared to provide information about your expected revenue and business activities.

Step 2: Get Your Contractor's Bond

Washington requires most contractors to obtain a surety bond of $12,000. This bond is not insurance. It is a three-party agreement between you (the principal), a surety company (the guarantor), and L&I (the obligee). The bond provides financial protection to consumers if you fail to fulfill your contractual obligations, cause property damage, fail to pay subcontractors or suppliers, or violate state contractor laws.

If a claim is filed against your bond and the surety company pays out, you are personally responsible for reimbursing the surety company. This is fundamentally different from insurance, where the insurer absorbs the loss.

Where to get a bond: Contact a licensed surety bond company. Many insurance agencies, including SmartInsured, can help you obtain a contractor's bond. The process typically involves a credit check and a simple application.

Cost: For contractors with good credit (typically a score above 650), the annual bond premium runs between $100 and $300 per year for the standard $12,000 bond. Contractors with lower credit scores may pay higher premiums or be required to put up collateral equal to the full bond amount.

Key requirements for your bond:

• The bond must name the Washington Department of Labor & Industries as the obligee
• It must remain active continuously for the entire duration of your registration
• Any lapse in your bond results in automatic suspension of your contractor registration
• The surety company must be authorized to do business in Washington State

Some specialty contractors, such as those working on public projects, may need higher bond amounts. Electrical contractors, for example, have separate bonding requirements through L&I's Electrical Section.

Step 3: Register for L&I Industrial Insurance

Washington operates a state-managed workers' compensation system known as industrial insurance. Unlike most states where employers purchase workers' comp from private insurers, Washington requires nearly all employers to participate in the state fund administered by L&I.

To register, follow these steps:

• Create an account on the L&I website at lni.wa.gov
• Complete the industrial insurance registration, providing details about your business, the number of employees, and the type of work you perform
• Select the appropriate risk classification codes for your work (L&I uses these codes to determine your premium rates, and rates vary significantly by trade)
• Understand your quarterly reporting obligations, which include reporting employee hours worked and paying premiums based on those hours and your classification rates

For sole proprietors: Workers' compensation coverage for yourself as the business owner is optional in Washington. However, it is strongly recommended. If you are injured on a job and do not have coverage, you will have no access to L&I benefits for medical treatment, lost wages, or disability. The cost of electing coverage for yourself is based on your classification rate and reported hours. Given the physical nature of construction work, skipping this coverage is a significant financial risk.

You must stay current on your quarterly L&I reports and payments. Late filings and missed payments generate penalties and interest, and prolonged non-compliance can result in suspension of your contractor registration.

Step 4: Obtain Liability Insurance

Here is where many new contractors get confused. Washington State does not legally require contractors to carry general liability insurance as a condition of registration. However, in practice, you cannot operate a viable contracting business without it.

Why general liability insurance is practically mandatory:

• Most general contractors require subcontractors to carry a minimum of $1,000,000 per occurrence and $2,000,000 aggregate in general liability coverage before they will hire you
• Many cities and counties in Washington require proof of liability insurance before issuing building permits
• Commercial property owners and property managers require it before allowing you on their properties
• Residential customers increasingly ask for proof of insurance before hiring a contractor
• Lenders and project financiers may require it as a condition of project funding

What general liability covers: Third-party bodily injury, third-party property damage, completed operations claims (damage that occurs after you finish a project), personal and advertising injury, and medical payments. This is different from workers' compensation, which covers your employees. General liability covers damage or injury you cause to others.

Cost: General liability insurance for Washington contractors typically starts at $64.99 per month, though your actual rate depends on your trade specialty, annual revenue, number of employees, and claims history. Higher-risk trades like roofing and demolition pay more than lower-risk trades like painting or finish carpentry.

Certificates of insurance: Keep certificates of insurance (COIs) ready to provide to clients, general contractors, and property owners at a moment's notice. Delays in producing a COI can cost you a job. Work with an agency that can issue certificates quickly, ideally same-day.

Step 5: Apply for Contractor Registration

With your business entity formed, bond in place, L&I industrial insurance active, and liability insurance secured, you are ready to apply for contractor registration.

The application process:

• Submit your application online through L&I's contractor registration portal
• Provide proof of your active contractor's bond (your surety company can submit this electronically to L&I)
• Provide proof of your L&I industrial insurance registration
• Pay the registration fee (currently $142 for most contractor types, though fees may change)
• Choose your specialty designation or designations, which define the types of work you are authorized to perform (general contractor, specialty contractor, or both, with specific trade categories)

Processing time: Standard processing takes approximately two to four weeks. L&I does offer expedited processing for an additional fee if you need your registration sooner. Check the L&I website for current expedited processing options and fees.

Once approved, you will receive your contractor registration number. This number must appear on all advertising, contracts, business cards, and vehicles used for business purposes. Verify your registration is active and correct through L&I's online Contractor Verification tool before beginning any work.

Step 6: Maintain Your Registration

Getting registered is only the beginning. Maintaining your registration requires ongoing attention to several obligations.

• Annual renewal: Your registration must be renewed each year. L&I sends renewal notices, but it is your responsibility to renew on time. Late renewals can result in a lapse in registration, which means you cannot legally perform work until it is reinstated.
• Keep your bond active: A lapse in your surety bond triggers automatic suspension of your contractor registration. Set up renewal reminders well in advance of your bond expiration date.
• File quarterly L&I reports on time: Even if you had no employees and no hours to report in a given quarter, you must still file a report. Missed filings result in estimated assessments, penalties, and interest.
• Update your registration when business information changes: If you change your business address, ownership structure, business name, or scope of work, you must notify L&I promptly.
• Display your registration number: Washington law requires your contractor registration number to appear on all advertising, business vehicles, contracts, and bid documents. Failure to display your number is a violation that can result in penalties.

Additional Insurance to Consider

General liability and workers' compensation cover the basics, but many contractors find they need additional coverage as their business grows.

• Commercial auto insurance is required if you use vehicles for business purposes. Your personal auto policy does not cover accidents that occur while driving for work. If you haul materials, drive to job sites, or use a work truck, you need a commercial auto policy.
• Tools and equipment coverage (inland marine) protects your tools, equipment, and materials in transit and at job sites. Standard property policies often exclude tools stored off-premises or in vehicles.
• Professional liability (errors and omissions) covers claims arising from design errors, project management mistakes, or faulty professional advice. This is especially relevant for design-build contractors and those who provide consulting or engineering services.
• Umbrella insurance provides an additional layer of liability protection above your general liability, auto, and employers' liability limits. Contractors working on larger commercial projects are frequently required to carry umbrella coverage of $1,000,000 or more.
• Builder's risk insurance covers structures under construction against damage from fire, wind, theft, and vandalism. This is typically purchased on a per-project basis and is often required by the project owner or lender.

Common Registration Mistakes to Avoid

New contractors frequently make avoidable mistakes during the registration process that cost them time and money.

• Operating before registration is approved. This is the most costly mistake. Performing any construction work before your registration is active violates state law and exposes you to significant fines.
• Letting your bond lapse. Even a one-day lapse triggers automatic suspension. Set calendar reminders and consider automatic renewal through your surety company.
• Missing quarterly L&I filing deadlines. Even quarters with zero activity require a filed report. Mark deadlines on your calendar for the last day of January, April, July, and October.
• Not updating registration when adding employees. If you start as a sole proprietor and later hire employees, you must update your L&I industrial insurance account and begin reporting and paying premiums for those employees immediately.
• Using a personal auto policy for business. Personal auto policies contain business-use exclusions. An accident while driving to a job site in your personal vehicle could result in a denied claim if you do not have commercial auto coverage.

Penalties for Non-Compliance

Washington takes contractor registration seriously, and the penalties for violations are steep.

• First offense for operating without registration: A fine of up to $5,000
• Repeat offenses: Fines of up to $10,000 per violation
• Habitual offenders: Criminal misdemeanor charges are possible for contractors who repeatedly operate without registration
• No lien rights: Work performed while unregistered does not qualify for mechanic's lien protection. This means you cannot file a lien to collect payment on projects completed without valid registration.
• Stop-work orders: L&I has the authority to issue stop-work orders that shut down your job site until compliance is achieved
• Civil liability: Homeowners who hire unregistered contractors may have additional legal remedies against those contractors, making lawsuits easier to pursue

These penalties apply to both the contractor and, in some cases, to anyone who knowingly hires an unregistered contractor. The financial and legal consequences of skipping registration far outweigh the time and cost of doing it properly.
