Contractor licensing

Washington contractor license requirements

Washington does not test general contractors, but every construction contractor must register with the Department of Labor & Industries (L&I), carry a surety bond and liability insurance, and show the registration number in all advertising and bids.

In Washington, the contractor license is a registration with the Department of Labor & Industries (L&I). There is no exam and no experience requirement for general or specialty registration. Instead, the state relies on money: every construction contractor must be bonded and insured before it can bid, advertise, or perform construction work. Trades like electrical and plumbing add separate licensing on top of the registration. The rule reaches anyone who constructs, remodels, repairs, or demolishes buildings, roads, or other real property.

General vs. specialty registration

The choice matters more than it looks. A general contractor can perform most types of construction work and can hire subcontractors in multiple specialties. A specialty contractor can work only in the specialty it registered in, and it cannot hire subcontractors. L&I regulates 63 specialties, including roofing, painting, HVAC, tree removal, and mobile home set up.

Say a siding company in Spokane registers as a specialty contractor to save on the bond. A homeowner asks it to replace two windows and some fascia as part of the job, and the owner wants to bring in a gutter installer. As a specialty contractor, the siding company cannot sub that gutter work out. If you plan to run jobs and hire subs, register as a general contractor from day one. Switching from general to specialty later does not drop your bond right away: L&I will not reduce the bond amount for 2 years.

How to register as a contractor in Washington

  1. Set up the business. Choose the structure and name. Corporations and LLCs form through the Secretary of State. Then register with the Department of Revenue to get a Uniform Business Identifier (UBI).
  2. Buy the surety bond. A Washington Continuous Contractor Surety Bond (F625-003-000) for $30,000 (general) or $15,000 (specialty), in your exact business name. The alternative is an Assignment of Account (F625-008-000) with cash, a CD, time deposit, or money market account at a bank or credit union with a Washington branch.
  3. Buy liability insurance. $200,000 public liability and $50,000 property damage, or a $250,000 combined single limit, with L&I listed as certificate holder.
  4. Complete the Application for Contractor Registration (F625-001-000). All signatures must be original and notarized. Copies are not accepted.
  5. Submit and pay $150.20. Visit a local L&I office, where staff can help complete and notarize the application, or mail it to Contractor Registration, P.O. Box 44450, Olympia, WA 98504-4450. Mailed applications have been taking 3 to 4 weeks to process. A registration card follows in about 2 weeks.

Rules that apply after you register

  • Registration number on everything. By law, every ad, bid, estimate, business card, and web listing must show your contractor registration number.
  • Model disclosure statement. Give customers the Model Disclosure Statement Notice to Customer (F625-030-000) on all residential jobs of $1,000 or more and on commercial projects of $1,000 to $60,000.
  • Keep bond and insurance current. If either cancels or expires, or you have an unsatisfied judgment, L&I suspends the registration and notifies you by certified mail within 2 days. Reinstatement takes proof of the fix and a $70.90 fee.
  • Renew on time. Renewal costs $150.20 online, by mail, or in person. Update any new bond or insurance first. L&I does not accept insurance certificates by email or fax.
  • Extra licenses. Lead based paint work on pre-1978 homes goes through the Department of Commerce Lead Paint Program, and pesticide application through the Department of Agriculture.

Washington is strict about unregistered work, and L&I warns of substantial penalties and fines for working without registering. For the GC, that means checking every sub before the first day on site. A bonded, insured, registered sub is also the one most likely to have workers' compensation in order.

Use L&I's Verify a Contractor, Tradesperson, or Business tool at secure.lni.wa.gov/verify. Check the registration status, the bond and insurance on file, and the general or specialty type. Do it at award and again before each payment, since a suspension can happen mid job when insurance lapses. Track the dates with a subcontractor COI tracking template. For payment rights on Washington jobs, see Washington mechanics lien law, and for public work, Washington prevailing wage.

Smart Business Automator stores each sub's L&I registration number, bond, and insurance expiration in one place and warns the office before a lapse can suspend a registration. See subcontractor compliance automation.
