Do I need a Washington contractor license?
Any contractor in the state of Washington who engages in construction activity is required to be licensed and insured with the Department of Labor and Industries. Chapter 18.27 of the Washington State Legislature outlines all rules and regulations for construction contractors.

How to get registered and licensed as a contractor in Washington
To become a licensed contractor, you must complete the following.
Step 1: Register your business with Department of Revenue

Fire Sprinkler Systems Contractor Bond
There are five levels of fire sprinkler contractors, and each level requires a matching surety bond. It is important to know which category you fall into so you can obtain the correct bond.
Level 1 fire sprinkler contractors work on the installation of sprinkler systems for single- or dual-family-occupied residential structures and their dedicated underground fire service mains. Additionally, any Level 1 contractor is required to have at least one employee certified as their Certificate of Competency Holder. Level 1 fire sprinkler contractors should post a $6,000 surety bond.
Level 2 fire sprinkler contractors inherit the same regulations as Level 1, but they can also work on installations in any structure up to a four-story structure. A $6,000 Level 2 Fire Sprinkler System Contractor Bond is required.

Level I&T fire sprinkler contractors can inspect and test work of wet and/or dry pipe fire protection sprinkler systems. Every contractor who either inspects or tests must secure a certificate of competence.
