Washington Contractor License Requirements
Washington doesn’t “license” general contractors the way most states do — it registers them, through the Department of Labor & Industries (L&I), under a bond-and-insurance model with no trade exam and no minimum experience requirement. Here’s exactly what L&I requires, including the one quirk nearly every third-party guide gets stale: the bond amount changed in 2024.

Quick facts
| Regulator | Washington State Department of Labor & Industries (L&I), under RCW 18.27 |
|---|---|
| What it’s called | Contractor registration, not a license — Washington’s program is built around bonding and insurance, not a trade exam |
| Prerequisite | Register your business with the Department of Revenue and obtain a Unified Business Identifier (UBI) number before applying — separate $90 Business License Application fee plus $10 annual renewal |
| Bond | $30,000 for general contractors, $15,000 for specialty contractors — raised from $12,000/$6,000 by HB 1534, effective for registrations and renewals on or after July 1, 2024 |
| Liability insurance | $200,000 public liability and $50,000 property damage, or $250,000 combined single limit; L&I must be listed as a certificate holder |
| Exam or experience | None for general or specialty contractor registration — a genuine exception among states. (Separately licensed trades — plumbing, electrical, elevators, mobile/manufactured home installation, boilers, asbestos — do have their own exam and education requirements, but those are distinct programs from general contractor registration.) |
| Registration fee | $150.20, per L&I’s current registration page (a separate reference, WAC 296-200A-900, still lists an older $141.10 figure — confirm the live fee on L&I’s payment screen before paying) |
| Renewal | Every 2 years; same $150.20 fee applies |
General vs. specialty registration
Washington splits contractor registration into two tracks: general contractors, who can take on a broad range of construction work, and specialty contractors, who are limited to a specific trade or scope. The core process is identical for both — register your business, get bonded and insured, pay the fee — but the bond amount differs: $30,000 for general, $15,000 for specialty. Neither track requires a trade exam or a minimum number of years of experience, which sets Washington apart from states like California or Virginia that gate licensure behind demonstrated experience and a classification exam. L&I’s own registration materials are explicit that the program exists to ensure contractors are bonded, insured, and accountable to consumers, not to test trade competency.
Steps to register
- Register your business with the Washington Department of Revenue’s Business Licensing Service and obtain a UBI number ($90 application fee, $10 annual renewal).
- Purchase a continuous surety bond in your exact business name — $30,000 for general contractor registration, $15,000 for specialty — filed directly with L&I by the surety company.
- Purchase general liability insurance meeting L&I’s minimums ($200,000/$50,000 split, or $250,000 CSL), with L&I listed as a certificate holder.
- Submit the Application for Construction Contractor Registration (L&I form F625-001-000) along with the $150.20 fee.
- Wait for L&I to process and issue your registration — there’s no exam to schedule or pass, so processing is largely a paperwork and verification step once the bond and insurance are on file.
Renewal
Washington contractor registrations run on a 2-year cycle and must be renewed on or before the expiration date. Renewal requires the same $150.20 fee and a current, valid bond and insurance certificate on file — there’s no continuing-education requirement tied to renewal, consistent with the program’s bond-and-insurance focus rather than a competency-based one. A registration that lapses for 30 or fewer days while the bond and insurance stay valid is treated differently than one that’s fully expired or revoked, per RCW 18.27 — but letting it lapse longer, or working while expired, exposes you to the same penalties as never registering at all.
Do I need to pass an exam to become a general contractor in Washington?
No. Washington’s contractor program is registration-based, not exam-based — L&I confirms there’s no trade exam and no minimum experience requirement for general or specialty contractor registration. This is a genuine structural difference from states like California (CSLB exam) or Virginia (experience-gated classes); don’t assume Washington works the same way.
Is “contractor registration” the same thing as a “contractor license” in Washington?
Functionally yes for most purposes — it’s the credential you need to legally advertise, bid, and perform contracting work in the state — but L&I’s own terminology is “registration,” not “license.” The distinction matters mainly because it signals the underlying model: Washington’s program is built around bonding and insurance accountability, not a licensing board testing trade competency.
How much did the contractor bond requirement change, and when?
HB 1534 raised the required bond from $12,000 to $30,000 for general contractors and from $6,000 to $15,000 for specialty contractors — the first increase in over 20 years. It applies to registrations and renewals on or after July 1, 2024, so a contractor whose registration hasn’t come up for renewal since before that date may still be shown with the old bond amount on some third-party sites; L&I’s own current registration page reflects the new $30,000/$15,000 figures.
Penalty for unregistered contracting
Under RCW 18.27.020, advertising, bidding, offering to do work, or performing any work as a contractor without being registered — or while your registration is suspended or revoked — is a gross misdemeanor, with each day worked or each worksite treated as a separate offense. Separately, L&I enforces its own escalating civil penalty schedule under WAC 296-200A-400 for working as an unregistered contractor: $1,200 for a first violation, $3,000 for a second, $5,000 for a third, and $10,000 for each subsequent violation within the same period (the director has discretion to reduce a first-offense penalty, but not below $600, if the contractor registers within 10 days of the notice of infraction).
Reciprocity with other states
Washington does not offer reciprocity for general or specialty contractor registration with any other state — every out-of-state contractor has to go through the same UBI, bond, insurance, and registration-fee process as a Washington-based one. (A Washington–Oregon reciprocity agreement does exist, but it covers only general journey-level electricians, a separate licensing program from general contractor registration — don’t assume it extends to contracting broadly.)
