In Washington State, a Model Disclosure Statement (RCW 18.27.114) is a notice requirement specifically for prime (general) contractors. Most general contractors include this required statement directly inside their customer contract. This is completely different from a subcontractor’s Notice to Owner, which is a separate paper document that subcontractors and suppliers must mail to the property owner to protect their lien rights.
Note: Failing to provide the Model Disclosure Statement completely bars a prime contractor from filing a mechanics lien and may incur potential fines from the Dept of Labor & Industries (L&I). Read our full guide below. Reviewed for accuracy by local lien specialists. Updated June 2026.
In Washington State, a Model Disclosure Statement, also known as a Notice to Customer, is a construction document that a direct contractor must provide to a property owner before starting work. It informs the owner about the contractor’s registration, bonding, and their rights to file a mechanics lien if unpaid. Click to download the form below.
The statement should follow the required Washington language under RCW 18.27.114. It should include the contractor’s legal business name, registration number, bond information, and other required notice language so the owner understands the lien risk. In practice, many general contractors include this statement directly in their customer contract instead of handling it as a separate, standalone document.
In Washington, a Notice to Owner is a document that protects a subcontractor’s or material supplier’s right to file a mechanics lien if they do not get paid. It is the same document as a Pre-Claim Notice or a Notice of Right to Claim Lien.
A Model Disclosure Statement, a Notice to Owner, and a Notice of Intent to Lien in Washington are three separate documents that serve completely different purposes at different stages of a construction project. Mixing them up could jeopardize your lien rights. Here’s how they compare side by side.
| Feature | Model Disclosure Statement Notice to Customer | Notice to Owner Pre-Claim Notice | Notice of Intent to Lien Final Warning |
|---|---|---|---|
| Who Sends It | Prime (general) contractors who contract directly with the property owner. | Subcontractors and material suppliers who do not have a direct contract with the owner. | Any unpaid party — contractor, subcontractor, or supplier before filing a formal lien. |

| What Is It? | A pre-contract disclosure given to the owner about the contractor’s registration, bond, and lien risk. Usually included directly in the contract. | A preliminary notice mailed to the owner to inform them that a lower-tier party is supplying labor, materials, or equipment on their project. | A final warning document sent to the owner demanding payment before a formal mechanics lien is recorded. |
| When to Send? | Before work begins. Owner must sign prior to any work commencing. | • New single-family residential: within 10 days of first furnishing • All other projects: within 60 days of first furnishing |
Only after payment is overdue. Typically sent before filing the actual lien. |
| Purpose | To disclose contractor credentials and warn the owner about potential lien risk before the project starts. | To establish and preserve future mechanics lien rights for the sending party. | To demand immediate payment and put the owner on notice that a lien will be filed if unpaid. |
| Labor Exemption | No exemption — required regardless of whether work is labor, materials, or both. | Exemption applies. Not required for liens based solely on labor. Confirmed by WA Supreme Court (2024). Labor Only = Exempt | No exemption — any unpaid party may send this notice. |
| Penalty for Failure | Complete loss of mechanics lien rights and potential fines from the Dept. of Labor & Industries. | Loss of lien rights for materials or equipment furnished outside the 10 or 60-day lookback window. | No statutory penalty — but skipping it reduces pressure on the owner to pay before the lien is recorded. |
You must send a Notice to Owner (Notice of Right to Claim a Lien) in Washington to preserve your legal right to file a mechanics lien. For lower-tier subcontractors and suppliers, failing to provide this notice removes your primary legal leverage for payment if the contractor or owner refuses to pay. It also informs property owners of who supplies materials or services, preventing surprise double payments.
The Washington Notice to Owner can be sent anytime, but it only protects work or materials within a specific “look-back” window before sending the notice. For commercial and general construction, this window covers materials or services supplied up to 60 days prior. In new single-family residential projects, it is limited to 10 days. While not legally required before starting work, sending the notice early helps secure your payment rights from the start.

A quick reference guide to RCW 18.27.114 requirements, project triggers, and what must be included in the statement.
If a contractor in Washington does not provide the required disclosure statement under RCW 18.27.114, they cannot file or maintain a lien claim related to that contract. Failure to provide the disclosure is considered a violation that can lead to enforcement actions.
No. Washington’s model disclosure requires the customer’s signature, and the state disclosure form says the contractor must be able to produce a signed or electronically signed copy on request. Notarization applies to the later Claim of Lien recorded with the county, not to the pre-contract disclosure itself.
No. The Model Disclosure Statement applies to contractors who contract directly with the owner under RCW 18.27.114. Subcontractors and suppliers protect private-project lien rights through the separate pre-claim notice described in RCW 60.04.031.
Generally, no. If you were required to send a Washington Notice to Owner and did not, you usually cannot enforce a mechanics lien for professional services, materials, or equipment. The main exception is a labor-only claim, because Washington law does not require the pre-claim notice for lien claims based strictly on labor.
