Navigating construction payment laws can be stressful. Here is everything you need to know about Washington mechanics lien deadlines so you don’t lose your right to get paid.
In Washington State, sending a Preliminary Notice (often called a Notice of Intent) is usually a mandatory first step to protect your right to get paid. However, the exact document you must send—and your deadline to send it—depends entirely on whether you are a prime contractor, subcontractor, or material supplier.
Washington state law (RCW 60.04) usually doesn’t require laborers providing only labor to send a pre-lien notice to protect their lien rights.
| Contractor Role | Notice Deadline & Requirements |
|---|---|
| Prime Contractors | Deadline: Before work begins Requirements:
|
| Subcontractors | Deadline: Within 60 days Requirements:
|
| Material Suppliers | Deadline: Within 60 days Requirements:

Missing a deadline in Washington means permanently losing your right to get paid. Whether you are a prime contractor, a subcontractor, or a laborer, the State of Washington applies the exact same strict timeline for filing and enforcing a mechanics lien (Chapter 60.04 RCW).

Yes, calendar days are used to calculate the deadline. However, if your 90th day lands on a weekend or a legal holiday when the county auditor’s office is closed, the deadline usually rolls over to the next consecutive business day.
If you miss the 90-day window, your lien rights are completely void. You cannot file a late mechanics lien in Washington under any circumstances, and the county recorder cannot grant extensions.

Yes. In Washington State, a contractor or supplier can record a mechanics lien with the county auditor without your direct knowledge, sometimes called a “silent lien.” However, Washington law (RCW 60.04.091) requires the claimant to serve a copy of the recorded lien to the property owner within 14 days of filing.
Yes, electronic signatures on lien waivers are generally accepted in Washington State as long as both parties agree to conduct the transaction electronically and the document clearly identifies the project and the amount being waived.
Yes. You are not legally required to hire an attorney to prepare or record a mechanics lien. However, because minor clerical errors or missed deadlines can completely invalidate the lien, many construction professionals choose to use a specialized lien filing service like Northwest Lien for accuracy.
In severe cases, yes. A lien does not immediately seize your property, but if the unpaid contractor successfully enforces the lien by filing a foreclosure lawsuit, the court can force the sale of the house to pay off the construction debt.
No. Washington State law does not require lien waivers to be notarized to be legally valid. However, some lenders or general contractors may write notarization requirements into their specific contracts.

The most reliable way is to perform a title search or check the public records at your local county auditor or recorder’s office. Under Washington law, the claimant is also required to mail you a copy of the lien within 14 days of recording it.
In Washington State, a mechanics lien is valid for exactly 8 months from the date it is recorded. If a lawsuit is not filed to enforce the lien before the 8 months expire, the lien becomes void and is no longer enforceable.
If you believe the lien is frivolous or legally invalid (such as a missed deadline or an unlicensed contractor), you can file a motion in county court to have a judge remove it. Otherwise, valid mechanics liens cannot simply be ignored; they must be settled, bonded around, or defeated in court.
Washington law does not specify a statutory minimum dollar amount required to file a mechanics lien. However, because of the costs associated with recording fees and potential legal enforcement, filing a lien for very small debts may not be financially practical.
Mechanics liens are strictly enforced, and even a small clerical error can invalidate your claim. The most common mistakes include:
The most common lien on personal property is a consensual lien, such as an auto loan or equipment financing, where the borrower voluntarily agrees to let the lender use the property as collateral until the debt is paid.
