What These Lopez Island Records Tell You

Lopez Island ranks #183 of our 200 launch pages by number of active registrations. The most common registered specialties here are general (57). 4 registrations expire within the next 90 days, so check the date again before signing a contract.

A "bond on file" means Washington L&I lists an uncancelled surety bond for that registration. Washington law requires a $30,000 bond for general contractors and $15,000 for specialty contractors (RCW 18.27.040). Electrical contractors are licensed under a separate L&I program, so their liability insurance is not part of the construction-contractor insurance dataset.
