How to File a Mechanics Lien in Washington
Step 1 — Confirm you have lien rights in Washington
Washington's recorded rules cover subcontractors and suppliers, general contractors, design professionals (RCW 60.04.031). Each of those roles has its own filing window — see Step 3. Washington rule detail: REQUIRED: Serve 'Notice to Customer' within 60 days of first furnishing. Covers only work done before notice was served plus 60 days after.
Step 2 — Send the Washington preliminary notice
Washington requires a preliminary notice 60 days, notice to owner (RCW 60.04.091). It is a precondition, not a formality. It must reach County Auditor and Owner and GC and Construction Lender and Construction Lender or Owner. Delivery: Certified Mail, Return Receipt Requested. Washington rule detail: File claim of lien within 90 days of last furnishing of labor or materials. Serve copy on owner within 14 days of filing.
Step 3 — Your Washington filing deadline
Washington sets the window by claimant role: • Subcontractors and suppliers: within 90 days of your last day of work or materials. • General contractors: within 90 days of your last day of work or materials. • Design professionals: within 90 days of your last day of work or materials. The clock runs from last date of furnishing — not your invoice date. Punch-list and warranty callbacks generally do not restart it. Washington rule detail: File claim of lien within 90 days. No prelim notice required for prime contractors.
Step 4 — Prepare and record the lien in Washington
Record in the county where the property sits, under RCW 60.04.141. The document must identify the property, the owner of record, the amount actually owed, and what you furnished. Overstating the amount can void the claim outright. Washington rule detail: Lien expires 8 months after filing. File suit within 8 months to enforce. Lien expires automatically if no suit filed.
Step 5 — Serve the recorded Washington lien
Washington requires service on County Auditor and Owner and GC and Construction Lender and Construction Lender or Owner. Use Certified Mail, Return Receipt Requested and keep the receipt. In many states an unserved lien is unenforceable even though it appears on title. Washington rule detail: Public: prime must pay sub within 10 days of receiving payment from public owner. Private: pay promptly per contract terms. Interest accrues on late public payments.
Step 6 — Enforce before the Washington deadline expires
You must sue to foreclose within 8 months (filing) (RCW 39.76.011). Miss it and the lien expires and title clears, leaving only a contract claim. Washington rule detail: Public retainage released 60 days after completion and acceptance. Private projects: per contract. Up to 10% retainage on public works.
Washington stop notice option
Washington also recognises a stop notice, which reaches undisbursed construction funds rather than the property itself (RCW 60.04.221). It can be used alongside a lien. Washington rule detail: WA STOP NOTICE (Bonded): On private projects with a construction lender, a claimant who has served the 60-day preliminary notice (or meets an exception) may serve a Stop Notice on the lender. Lender must withhold sufficient funds. Must bond the stop notice (double the amount claimed) to make it effective. File before final disbursement.
Retainage rules that affect your Washington claim
Washington treats retainage on its own schedule (RCW 60.28.021), so money still held back may have a different due date than your progress billings. Washington rule detail: WA NOTICE OF FURNISHING (Alternative to Prelim Notice): For certain claimants including professional service providers and those furnishing materials only (no labor), may use Notice of Furnishing in lieu of or in addition to the 60-day Notice to Customer. Must serve within 10 days of first furnishing. Covers only work after date of service.
Other Washington requirements that void liens
• WA Design Professional Lien: Licensed architects, engineers, and surveyors have lien rights in Washington. Must serve 60-day preliminary notice within 60 days of first furnishing services. File claim of lien within 90 days of last furnishing. • ANTI-WAIVER: RCW 60.04.171 makes void any contractual provision requiring a claimant to waive lien rights BEFORE performance. A conditional lien waiver given in exchange for a specific payment is valid only to the extent of that payment. Blanket advance waivers of lien rights are void in Washington. • WA STOP NOTICE: Served on construction lender or owner. Same 90-day deadline as lien recording. Owner can bond around with 150% of claim amount. Very strong remedy in WA. Requires prior 60-day preliminary notice. Freezes construction loan funds. • WA NOTICE OF COMMENCEMENT (RECOMMENDED): While not legally required in Washington, recording a Notice of Commencement is recommended to establish the project priority date and protect the owner against claims predating the lender's deed of trust. Must be posted on the job site. Opens formal lien protection period.
Frequently Asked Questions
How long do I have to file a mechanics lien in Washington?
Washington requires the lien to be recorded within 90 days, measured from last date of furnishing. The exact window depends on your role — subcontractors and suppliers: within 90 days of your last day of work or materials.
Do I need to send a preliminary notice before filing in Washington?
Yes. Washington requires a preliminary notice 60 days (notice to owner). Failing to send it on time generally forfeits your lien rights entirely, regardless of how much you are owed.
Where do I file a mechanics lien in Washington?
File with the county recorder's office in the county where the property is located. Filing in the wrong county does not preserve your deadline, and re-filing in the correct county after the deadline will not save the claim.
What happens if I miss the Washington filing deadline?
Your lien rights are extinguished. Washington courts do not grant extensions for missed mechanics lien deadlines. You would be left with a breach-of-contract claim against whoever hired you, which carries no security interest in the property and is far harder to collect.
How long does a mechanics lien last in Washington?
Once recorded, you must file suit to enforce within 8 months (filing). If you do not, the lien expires automatically and no longer clouds the property's title.
