Idaho Construction Lien FAQ

In Idaho, a mechanics lien must be filed within ninety (90) days of the claimant’s last furnishing of labor, materials, equipment, or professional services to the project. This deadline is calculated from the last day meaningful, contract-related work was performed, not from when payment was due or negotiations ended. 

Yes. In Idaho, most subcontractors, suppliers, equipment rental companies, and design professionals who do not have a direct contract with the property owner must send a Notice of Claim of Lien Rights. This preliminary notice must be served within forty-five (45) days of first furnishing labor or materials. The purpose of the notice is to alert the property owner early in the project that lower-tier parties are involved and may later assert lien rights if unpaid. Failure to timely send this notice may permanently bars lien rights.

Idaho grants mechanics lien rights to:

• General contractors

• Subcontractors

• Sub-subcontractors

• Material suppliers

• Equipment rental companies

• Laborers

• Architects, engineers, surveyors, and other design professionals

Lien rights apply to private construction projects. Public projects require bond claims instead of liens.

If you miss the required Idaho lien deadline (90 days) you permanently lose your mechanics lien rights.

An Idaho mechanics lien must be recorded with the County Recorder in the county where the property is physically located. Filing the lien in the wrong county or office can invalidate the lien, even if it was otherwise timely and accurate. Recording the lien places it in the public record and formally asserts the claimant’s interest in the property.

After recording the mechanics lien, Idaho law requires the lien claimant to file a foreclosure lawsuit within six (6) months of the lien’s recording date. This enforcement deadline is strictly applied. If no lawsuit is filed within this six-month period, the lien automatically expires and becomes unenforceable, regardless of ongoing settlement discussions or promises of payment.

An Idaho lien claim must include detailed and accurate information. Idaho Mechanics Lien must include the following information:

• Claimant’s legal name and address

• Property owner’s name

• Hiring party’s name

• Legal property description

• Description of labor, materials, equipment, or services provided

• Amount claimed as unpaid

• Date of last furnishing

• Claimant’s signature and verification

No. Idaho does not impose a minimum or maximum dollar amount for mechanics liens. An Idaho lien may be filed for any unpaid amount owed for qualifying labor, materials, or services. However, the lien must reflect only the amount actually due after all credits and payments. Intentionally or negligently overstating a lien amount can expose the claimant to damages or invalidate the lien.

Yes. Idaho allows multiple contractors, subcontractors, suppliers, or design professionals to file separate mechanics liens against the same property if each independently provided labor or materials and was not paid. Each lien is evaluated on its own compliance with notice, filing, service, and enforcement requirements, and multiple liens may coexist on a single project.

If the customer pays you the full amount owed after you have recorded a lien, you have a legal obligation to formally clear the lien from the property records.

You must prepare and file an Idaho Discharge of Lien (or Release of Lien) with the same office where the original lien was recorded.
