Washington Construction Lien Laws: A Homeowner's Complete Guide
Washington Construction Lien Laws: A Homeowner's Complete Guide
Last updated: March 2026 | Based on RCW 60.04 (Mechanics' and Materialmen's Liens)
Construction liens—also called "mechanic's liens" or "materialman's liens"—are one of the most powerful tools in construction law. They allow contractors, subcontractors, and suppliers to place a legal claim on your property if they're not paid for work or materials. This guide explains how Washington's lien laws work and how to protect yourself.
What Is a Construction Lien?
A construction lien is a legal claim against your property that can be filed by anyone who provided labor, materials, or professional services for improvements to your property and wasn't paid.
Why this matters to homeowners:
- Even if you paid your general contractor in full, subcontractors and suppliers who weren't paid can still lien your property
- A lien creates a "cloud on title" that makes it difficult to sell or refinance
- If a lien is foreclosed, you could lose your home
- You could end up paying twice for the same work
Who Can File a Lien in Washington?
Under RCW 60.04, the following parties can file a construction lien:
| Party | Examples |
|---|---|
| Prime/General Contractors | The company you hired directly |
| Subcontractors | Plumbers, electricians, roofers hired by your contractor |
| Material Suppliers | Lumber yards, plumbing supply houses, appliance dealers |
| Equipment Renters | Companies that rent excavators, scaffolding, etc. |
| Laborers | Individual workers (though typically through their employer) |
| Design Professionals | Architects, engineers, surveyors |
Who CANNOT file a lien:
- Unregistered contractors (RCW 60.04.041)
- Parties who failed to give required notice (for lower-tier parties)
- Parties who missed filing deadlines
The Pre-Lien Notice System
Washington has a notice system designed to warn homeowners about who is working on their property and has potential lien rights.
When Notice is Required
| Party | Notice Required? |
|---|---|
| Prime contractor (hired by homeowner) | No (but must give disclosure statement) |
| Subcontractor hired directly by prime contractor | No |
| Sub-subcontractors (2nd tier and below) | YES |
| Material suppliers not contracting with owner | YES |
The "Notice to Owner" Form
Parties who don't contract directly with you must send a "Notice to Owner" to preserve their lien rights. This notice:
- Must be in writing (specific form required by RCW 60.04.031)
- Must be sent via certified/registered mail or delivered personally
- Protects lien rights only for work done 60 days before the notice (or 10 days for new single-family construction)
What the notice means:
- It's NOT a lien
- It's NOT a demand for payment (yet)
- It IS a warning that this party has potential lien rights
- It IS your cue to verify your contractor is paying their bills
What to Do When You Receive a Notice to Owner
- Don't panic — This is standard procedure, not an accusation
- Contact your contractor — Ask what arrangements they've made to pay this party
- Request lien releases — Before making payments to your contractor
- Consider joint checks — Pay the contractor AND the sub/supplier together
- Withhold payment if you suspect your contractor isn't paying subs
Special Rules for Owner-Occupied Homes
Washington provides extra protection for homeowners living in their single-family residence.
Repair/Remodel of Owner-Occupied Homes
For subcontractors and suppliers working on your existing, owner-occupied home:
Their lien rights are LIMITED to:
- Only amounts you haven't yet paid to your contractor at the time you receive their notice
- They cannot lien beyond what you still owe
Example:
- Your contract is $50,000
- You've paid $40,000
- A supplier sends you notice that your contractor owes them $15,000
- Maximum they can lien: $10,000 (the amount you haven't paid yet)
This is why it's crucial to not overpay your contractor and to pay in draws tied to work completion.
New Construction
For new single-family home construction, the rules are less protective:
- Full lien rights for the contract amount exist
- Notice only protects work done 10 days before notice (not 60 days)
- Owner-occupier limitations don't apply until you actually occupy the home
Lien Filing Deadlines
Critical timeline every homeowner should know:
| Event | Deadline |
|---|---|
| Work stops (or last materials delivered) | Day 0 |
| Deadline to file lien | 90 days |
| Deadline to send copy to owner | 14 days after filing |
| Deadline to file foreclosure lawsuit | 8 months after filing |
The 90-Day Rule
A lien claimant must record their lien with the county auditor within 90 days of:
- Last day labor was performed
- Last day materials were delivered
- Last day professional services were provided
- Last day employee benefit contributions were due
If they miss this deadline, they lose their lien rights (though they may still have other legal remedies).
The 8-Month Foreclosure Deadline
After filing a lien, the claimant has 8 months to file a lawsuit to foreclose. If they don't:
- The lien automatically expires
- You can petition the court to remove it
- They cannot re-file for the same claim
Lien Priority: Who Gets Paid First?
Washington lien law determines which creditors have priority if your property is foreclosed:
General Priority Rules
- Property taxes — Always first
- Construction liens — Priority dates from when work began or materials first delivered
- Recorded mortgages — Priority based on recording date
- Later encumbrances — Junior to the lien
Key Rule for Construction Liens
Construction liens are prior to any mortgage or deed of trust that was:
- Recorded after work began on the improvement
- Unrecorded at the time work began
This means if you have a construction loan, the lender likely recorded their mortgage before construction started, giving them priority. But if you refinance during construction, the new lender's mortgage may be junior to existing lien rights.
How to Protect Yourself from Liens
Before the Project Starts
- Hire only registered contractors — Verify at secure.lni.wa.gov/verify
- Get everything in writing — Detailed contract with scope, price, timeline
- Ask about subcontractors — Who will be working on your project?
- Set up a payment schedule — Tied to work completion milestones
- Never pay in full upfront — Standard is 10-50% deposit, balance in draws
During the Project
- Track all notices — Keep a file of every Notice to Owner you receive
- Request lien releases — Before each payment to your contractor
- Use joint checks — Make checks payable to contractor AND sub/supplier
- Verify payments — Ask your contractor for proof they're paying subs
- Don't overpay — Pay only for work actually completed
At Project Completion
- Get final lien releases — From every party that sent you a notice
- Hold back retainage — Common to withhold 5-10% until punch list is complete
- Wait 90 days — Consider holding final payment for 90 days (the lien filing window)
- Request sworn statements — Contractor certifies all subs/suppliers are paid
Lien Releases: Your Best Protection
A lien release (or "lien waiver") is a document where a contractor, subcontractor, or supplier gives up their right to file a lien for payment already received.
Types of Lien Releases
| Type | When Used | Risk Level |
|---|---|---|
| Conditional — Upon payment | Before payment clears | Lower risk |
| Unconditional — Payment received | After payment clears | Very low risk |
| Partial — For work to date | During project | Covers only past work |
| Final — For all work | At project end | Releases all claims |
What to Request
At each payment:
- Unconditional lien release from contractor for previous payment
- Conditional lien release for current payment
- Unconditional releases from subs/suppliers who sent notices
At final payment:
- Final unconditional lien releases from ALL parties
- Contractor's sworn statement that all have been paid
Under RCW 60.04.071, if you pay and request a release, the claimant must immediately provide one. If they refuse, you can go to court and recover attorney fees and damages.
What to Do If a Lien Is Filed Against Your Property
Step 1: Don't Panic, But Act Quickly
You have time to respond, but don't ignore it:
- The lienholder has 8 months to foreclose
- You have options to resolve or challenge the lien
Step 2: Verify the Lien Is Valid
Check that:
- The claimant is a registered contractor (if applicable)
- Notice requirements were followed
- The lien was filed within 90 days
- You received a copy within 14 days of recording
- The amount claimed is reasonable
Step 3: Try to Resolve It
Often liens result from disputes between your contractor and their subs:
- Contact the lienholder — Understand their claim
- Contact your contractor — Demand they resolve it
- Mediate — Many disputes can be resolved through mediation
- Pay the sub directly — Deduct from what you owe the contractor
- Bond the lien — Post a bond to remove the lien from your property while disputing
Step 4: Challenge a Frivolous Lien
Under RCW 60.04.081, you can petition the court to remove a lien that is:
- Frivolous — Filed without reasonable cause
- Clearly excessive — Amount claimed is obviously inflated
If you win, the court will:
- Release the lien
- Award you attorney fees and costs
If you lose, you'll pay the lienholder's attorney fees.
Foreclosure: The Nuclear Option
If a lien isn't resolved, the claimant can foreclose — force the sale of your property to satisfy their claim.
The Foreclosure Process
- Lienholder files lawsuit (within 8 months of lien recording)
- All lienholders and parties with interests are served
- Court determines validity and priority of liens
- If liens are valid, court orders sale
- Sale proceeds distributed by priority
Defenses to Foreclosure
- Lien was filed late (beyond 90 days)
- Required notices weren't given
- Claimant isn't a registered contractor
- Amount is inflated or fraudulent
- You already paid for the work
- Lien wasn't properly served on you
Understanding the Contractor Disclosure Statement
By law, contractors must provide a Disclosure Statement (Form F625-030-000) for:
- Residential contracts of $1,000 or more
- Commercial contracts from $1,000 to $60,000
This disclosure must be provided before the contractor can file a valid lien (RCW 18.27.114).
What the disclosure tells you:
- Your potential exposure to liens
- How the lien system works
- How to protect yourself
- The contractor's registration number
If your contractor didn't give you this disclosure, they may lose their lien rights.
