⚠️ Preliminary Notice Required

Washington's Preliminary Notice Requirement

Washington requires subcontractors and material suppliers (not in direct contract with the owner) to serve a "Preliminary Notice" within 60 days of first furnishing. Without it, lien rights are limited to the 60 days before the notice was served.

Deadline: 60 days from first furnishing labor or materials
Commercial vs Residential

Does the Property Type Change Your Deadline?

Same notice and filing requirements. Washington's residential homeowner protection laws require additional disclosures for residential work — verify with local counsel.

Common Mistakes

What Contractors Get Wrong in Washington

1
Serving the Preliminary Notice late — limits lien rights to work done in the 60 days before notice
2
Failing to serve all required parties (owner, GC, and lender)
3
Missing the 90-day lien filing deadline after project completion or last furnishing
