# Contractor trades in Washington — contractor-wa

> The 85 specialties L&I records, and how many contractors hold each.

## The trades, and who holds them

A registration carries exactly one specialty. 85 appear in the file; 68 of them have a page here.

### One licence, one specialty

Unlike some registers, this one records a single specialty per
registration — so these pages do not overlap, and their totals add up. A
business that does two trades holds two registrations, which is why
161,230 registrations belong to 149,441 businesses.
