Mechanic’s lien

Short definition

A mechanic’s lien (in Washington, formally a construction lien under RCW 60.04) is a legal claim a contractor, subcontractor, or supplier can file against your property if they aren’t paid for labor or materials. The lien attaches to the real estate, follows it through sale, and has to be cleared before you can refinance or sell. In WA, the right is heavily regulated — most subs must send you a pre-claim notice within 60 days, and you can protect yourself with lien waivers tied to each payment.

What it is

When a plumber, supply house, or apprentice provides labor or material that improves your home, WA gives them a security interest in the property until they’re paid. That security interest becomes a recorded lien if they file a claim against your title. It’s the construction-trades equivalent of a tax lien — the property itself is collateral.

The mechanics in Washington (RCW 60.04):

• Pre-claim notice (the 60-day form). Most subcontractors and material suppliers must mail you a “Notice of Right to Claim Lien” within 60 days of first delivering material or labor on the job. If they don’t, they generally lose the right to lien for anything before that date. The general contractor you signed with usually doesn’t need to send this notice for typical residential repair work.
• Lien claim (the 90-day filing). The lien itself has to be filed in county records within 90 days of the last day labor or materials were furnished. Past 90, the right is gone.
• Foreclosure (the 8-month window). Even after filing, the lienholder must move to foreclose within 8 months — otherwise the lien expires.

You’ll see the term most often in two places:

• The Notice to Customer / Disclosure Statement that any WA contractor must hand you before signing a contract over $1,000 (RCW 18.27.114). The form spells out lien rights.
• The Notice of Right to Claim Lien envelopes that show up in the first two months of any meaningful project — supply house, drywaller, electrician, plumber’s sub, anyone on the chain.

Why it matters to a homeowner

The lien rule is the reason the same plumber’s invoice can hit your title twice: once when you pay the GC, and a second time when the GC fails to pay the supply house and the supply house liens your home anyway. Your protection is procedural, and it costs nothing to use:

• Read the Notice to Customer before you sign a contract over $1,000. The contractor must give it to you in WA. If you didn’t get one, that contract is unenforceable on the contractor’s side and you should question it.
• Track every Notice of Right to Claim Lien that arrives in the first 60 days. Each one names a sub or supplier you should know about.
• Demand lien waivers tied to every payment. A “conditional waiver upon progress payment” releases the contractor’s lien rights for the work covered by that check. A clean stack of waivers is your audit trail if a sub later claims they weren’t paid.
• Use joint checks for big-ticket materials. A check made out to “Plumbing Co. AND ABC Supply” can only be cashed if both endorse it — which means the supply house gets paid before the GC pockets the money.

When a plumber’s quote talks about “lien rights,” “notice,” or “release,” they are referring to this statute. Homeowners who recognize the vocabulary catch the missing-disclosure scams before signing.

When you’ll encounter this term

• Signing a residential plumbing contract over $1,000 — the WA Notice to Customer disclosure references it
• A “Notice of Right to Claim Lien” envelope arrives in the first 60 days of a project from a sub or supplier you didn’t hire directly
• A lien claim shows up on a title-search before refinancing or sale
• A contractor’s estimate or invoice mentions “lien waiver” as a payment condition
• A plumber’s “second fix” or trim-out invoice references the disclosure form

Common variants and disambiguation

• Construction lien (RCW 60.04 statutory term) and mechanic’s lien (colloquial term) refer to the same thing in residential plumbing context.
• Mechanic’s lien (RCW 60.04, real-property construction) vs. automotive mechanic’s lien (RCW 60.08, vehicle repair). Different statutes, different remedies.
• Pre-claim notice (60-day “Notice of Right to Claim Lien”) vs. the lien claim itself (the 90-day filing). The first is a warning; the second is the actual lien on title.
• Lien waiver (releases the right after payment) vs. lien bond (different procedure, removes the lien from title in exchange for a surety bond — used when fighting a contested claim).

Scam-prevention checklist

• A contractor who refuses to provide the Notice to Customer / Disclosure Statement on a job over $1,000 is violating RCW 18.27.114. Walk away.
• A contractor who refuses to provide lien waivers in exchange for payment is preserving the right to lien you for work you’ve already paid for. Walk away.
• An invoice marked “paid” is not the same as a lien waiver. Insist on the waiver.
• Confirm the contractor and the contractor’s bond on WA L&I’s Verify a Contractor page before any payment changes hands. See WA L&I license.

Washington note

WA’s construction-lien chapter is RCW 60.04. Two pieces of the chapter routinely surprise homeowners:

• You can owe twice. If your GC pockets your payment instead of paying the supplier, the supplier’s lien rights against your home are intact. Lien waivers from each tier of the chain are the only cure.
• The 60-day pre-claim notice resets. A sub who shows up partway through a job has 60 days from their first work — not from the start of the project — to send the notice. Late-arriving subs sometimes miss the window, voiding their lien right.

WA L&I publishes the “Notice to Customer” / Disclosure Statement template and maintains the contractor-licensing rules (RCW 18.27) that intersect with lien rights. A contractor who isn’t licensed and bonded under L&I generally can’t enforce a lien at all.

DIY scope

This is a contract-and-paperwork subject, not a wrench subject. Get the Notice to Customer in hand before signing anything. Track every pre-claim notice in a folder for the project. Get a signed lien waiver in exchange for every payment. If a lien claim hits your title, talk to a real-estate attorney before paying it off — there are procedural defenses (no pre-claim notice, lapsed deadline, bonded-off claim) that can void it.
