Washington Concrete Contractor License Requirements (2026)
By Gabriel Giner, Editor · Source checked 2026-09-08
Washington registers concrete contractors as either general contractors or the Concrete specialty (BI); it does not issue a separate concrete occupational license. A specialty contractor may perform only its registered specialty. The statewide rule answers only the starting licensing question. Before signing a concrete contract, match the exact scope, project type, value, permits, and any separately regulated work to the authority identified in the sources below.

Step-by-Step Application Roadmap
- Identify the governing route. Register with L&I as a general contractor or Concrete specialty contractor and keep the registration, bond, and insurance in the exact business name.
- Confirm scope and project type. Match residential, commercial, public-right-of-way, and specialty work to the actual governing classification or local requirement.
- Complete current filings. Use the cited regulator’s current application, bond, insurance, tax, and permit instructions.
- Assemble the project-specific file. Keep the classification or registration record, insurance or bond evidence, contract scope, and the documents required by Washington's permitting authority together before applying for a permit or beginning work.
- Keep state authority and project approval aligned. Do not let a broad contractor credential, registration, or specialty label substitute for the actual project permit, plan review, inspection, or separately licensed trade requirement.

This guide uses the state-specific concrete route rather than inherited trade requirements.

Bidding outside the actual concrete scope
A classification, registration, or exemption must match the particular concrete scope and project facts; it is not blanket authority for unrelated or separately regulated work.
