Washington Masonry Contractor Registration Requirements (2026)

The Washington State Department of Labor & Industries (L&I) registers all construction contractors under RCW 18.27 (Registration of Contractors Act). Washington does not require a trade competency exam for masonry — it operates a registration model focused on bond, insurance, and UBI tax identification. Masonry contractors register as Specialty Contractors in the Masonry category. Any person contracting for masonry work for compensation in Washington must be registered before bidding or advertising. This page documents the verified path including bond sizing, mandatory GL and workers comp, WISHA silica enforcement, and TMS 402/602 plus IBC Chapter 21 compliance.

The Licensing Authority

Licensing for this trade is governed by Washington State Department of Labor and Industries (L&I), the agency that issues and regulates the credential under Revised Code of Washington Chapter 18.27 (Contractors); Chapter 19.28 (Electricians); Chapter 18.106 (Plumbers). L&I registers contractors statewide, certifies individual electricians and plumbers, administers prevailing wage, and conducts complaint investigations.

Baseline Eligibility

Eligibility begins with two baseline checks: the applicant must be 18 or older and must provide a valid Social Security Number or Individual Taxpayer Identification Number (ITIN). No Washington residency requirement. Out-of-state registrants must designate a Washington registered agent.

Good moral character

L&I reviews prior registration discipline and outstanding judgments from prior Washington registrations.

Background investigation

No fingerprint or criminal background check required for L&I registration. Prior L&I violations and unpaid judgments from a prior registration block new registration.

Experience and Education Requirements

The cited source set does not publish a fixed year-based experience threshold for this credential. The controlling requirement is no state-level experience minimum; Washington registers contractors without a competency exam.

Accepted proof of experience or eligibility

UBI (Unified Business Identifier) from the Washington Department of Revenue
Surety bond or cash deposit on file with L&I
Certificate of insurance meeting L&I minimums

Education substitution

Not applicable — Washington does not impose an experience requirement for specialty contractor registration.

The Licensing Examination

No written state trade examination is mandated for this credential in the cited materials. Instead, the operative process is: No state competency exam

Examination fee: No exam fee — Washington does not administer a masonry trade or business and law exam for L&I registration.

Financial Security and Insurance

The applicant must secure and file a $12,000 surety bond before the L&I will release the license.

General liability

L&I requires a minimum $250,000 public liability and $50,000 property damage (or combined single limit of $300,000) certificate of insurance under RCW 18.27.050.

Workers' compensation

Workers' compensation coverage through the Washington State Fund (L&I) is mandatory for all employees under RCW 51.12. Washington does not allow private workers compensation except for very limited self-insurance. Masonry is classification 0302 with one of the highest premium rates in the state fund.

Additional financial requirements

No financial statement required for specialty masonry registration.

Fee Schedule

Fee	Amount
Application (non-refundable)	$125
Initial license	$125
Renewal (every 2 years)	$125

License Renewal

The Washington Specialty Masonry Contractor Registration — L&I must be renewed every 2 years. The fee to renew is presently $125. Washington L&I registrations renew every two years. Any lapse in bond or insurance automatically suspends the registration and triggers an RCW 18.27.114 contract voidance notice to customers.

Continuing education: No CE required. Bond and insurance must remain continuously in force.

Reciprocity Map

Washington grants no NASCLA reciprocity for this classification.

Reciprocal State	Accepted Exam	Conditions
Oregon	Limited reciprocity	Oregon CCB and Washington L&I share registration data but do not waive bond or insurance.
Idaho	No reciprocity	Idaho Public Works contractor registration is separate; no bilateral waiver with L&I.

Washington L&I is a registration regime (no competency exam), so formal trade exam reciprocity does not apply. Out-of-state masonry contractors must register and post the $12,000 bond like any in-state registrant.

The Licensing Roadmap

Form the business entity and obtain UBI. Register with the Washington Secretary of State and Department of Revenue to receive a Unified Business Identifier (UBI) number.
Open the L&I workers compensation account. File with L&I Employer Services for State Fund workers compensation under classification 0302 (masonry).
Bind general liability insurance. Minimum $250,000 public liability and $50,000 property damage (or $300,000 CSL) certificate naming L&I as certificate holder.
Post the $12,000 contractor bond. Specialty contractors post a $12,000 surety bond or cash deposit under RCW 18.27.040.
Submit the L&I Contractor Registration Application. File Form F625-001-000 with $124.80 registration fee, UBI, bond, insurance certificate, and specialty category election (Masonry).
Receive the Contractor Registration number. L&I issues a registration number that must appear in all advertising, contracts, and bids per RCW 18.27.100.
Implement WISHA silica written exposure control plan. Washington WISHA (Division of Occupational Safety and Health, state plan) enforces WAC 296-840 mirroring 29 CFR 1926.1153 with stricter recordkeeping.

Common Application Pitfalls

The following pitfalls summarize the issues most likely to delay, return, or derail a Washington Masonry application based on the published board instructions and source materials cited on this page.

Bond or insurance lapse

Any lapse in the $12,000 bond or $250,000/$50,000 GL automatically suspends the L&I registration. All work performed during the lapse is unregistered contracting and exposes the contractor to double damages under RCW 18.27.080.

Advertising without registration number

RCW 18.27.100 requires the L&I registration number on every bid, advertisement, contract, and business card. Missing it draws $1,000 infractions from L&I compliance inspectors.

Private workers comp instead of State Fund

Washington requires State Fund workers compensation except under narrow self-insurance rules. Contractors who purchase private workers comp outside the State Fund face immediate L&I assessment and back premiums.

Anchored veneer ties at wrong spacing

Washington SDC C and D seismic zones (Puget Sound) require corrosion-resistant ties at reduced spacing per TMS 402. Seattle and King County inspectors fail jobs with undersized ties in seismic zones.

WISHA silica plan absent

Washington WISHA inspectors target masonry sites under WAC 296-840. Missing written exposure control plans draw immediate citations with WA-specific recordkeeping penalties higher than federal.
