Can this business work under this registration? Can work while it stays active.

The registration has 386 days left before it expires on Nov 21, 2027. Check that date against your project timeline.

Checks for Electricians

Electrical work is regulated under RCW 19.28 by the L&I electrical program, separately from general registration. Check the business's electrical contractor license and each worker's electrician certificate.
Most electrical work needs a permit and inspection from L&I or a city with its own program.
Electrical contractor records usually show a bond but no construction insurance record; that is expected.
