What Washington Law Requires
Preliminary notice within 60 days
Under Washington's Mechanics' Lien Act (RCW 60.04), second-tier subs and suppliers must serve a preliminary notice within 60 days of first furnishing. Miss the deadline and your right to file a lien is gone — no exceptions.
Lien must be filed within 90 days
After completing work, Washington claimants have 90 days to record their lien with the county. Miss that and there's nothing left to enforce. GCs need to know where every sub stands to manage their own risk.
COI requirements are contractual
Washington doesn't set a statewide insurance minimum by statute, but every GC enforces COI requirements contractually. An expired certificate on an active job site puts you on the hook for your sub's liability.
W-9s before the first check
Federal law requires a W-9 from any sub you pay $600 or more in a year. Washington construction moves fast — SubPaperz collects W-9s digitally so you're never scrambling at tax time.
We're not lawyers — this is general information, not legal advice. Talk to a Washington construction attorney for guidance specific to your situation.
Every Washington GC has been here. It doesn't have to keep happening.
In Washington, that window is firm. A sub without lien rights has no leverage, which means you have less leverage upstream when draws get disputed.
In Washington, that liability can land on you. One incident without a valid COI can cost more than every job you've done this year.
Your subs are on job sites all day. Hunting down paperwork after hours shouldn't be part of your business model.
