To file a mechanics lien in Idaho, you must record a notarized claim with the county recorder where the property is located within 90 days of your last day of work. This strict statutory deadline protects your right to secure payment for construction labor or materials.
Note: Missing the 90-day recording window or the tight 5-day service deadline generally invalidates your claim completely. Read our full step-by-step guide below, reviewed for accuracy by our local lien specialists. Updated June 2026.

To file an Idaho construction lien, you must follow a strict statutory process. Missing any of these steps could invalidate your claim.
Before recording the lien, the following project rules and requirements must be followed:
Your Claim of Lien must be notarized and contain the following information:
Submit the notarized Claim of Lien either in person or by mail to the County Recorder’s office in the county where the property is located. Be sure to check the county’s website in advance, as you will need to pay a recording fee.
Within 5 business days of recording the lien, serve a copy of the Claim of Lien to the property owner or reputed owner, either in person or by certified mail with return receipt.
Filing a lien temporarily holds the property’s title. In Idaho, you must file a foreclosure lawsuit within 6 months and record a lis pendens. Once paid, file a lien release.

An Idaho mechanics lien is a statutory claim against a property for unpaid work by contractors, subcontractors, or suppliers. It can hinder the sale or refinancing of the property and may lead to foreclosure to recover the owed amount.
Under the Idaho mechanics lien statute (Idaho Code 45-507), many construction professionals can secure a claim. Eligible parties include:
Idaho law does not strictly require a written contract to secure your lien rights, though having one is highly recommended to prevent disputes.
General contractors working on residential projects over $2,000 must provide a specific written disclosure to the homeowner before signing a contract. Failing to provide this Idaho contractor disclosure form over $2000 could strip away your claim rights completely. It may also trigger consumer protection violations.
The best way to satisfy the Idaho residential disclosure requirement is to bake it directly into your standard prime contract. You can include it as an integrated section or a dedicated exhibit to help ensure the disclosure does not get lost in pre-construction paperwork.
The strict Idaho mechanics lien deadline is 90 days from the last date you actively supplied labor or materials to the project. The Idaho 90-day lien rule is rigid for those who miss it. Performing trivial touch-ups, punch-list tasks, or warranty work generally does not extend this 90-day window. You should mark this exact date on your calendar the moment you finish your primary scope of work. Missing the deadline could invalidate your claim.
You must record your document physically or electronically with the County Recorder office in the county where the property sits. Do not submit the paperwork online to the Secretary of State.
Your form must include a formal notary acknowledgment and a full official property description. A simple street address is insufficient for county recording standards.
You can locate the property description using these methods:
County recording fees typically range from $10 to $15 for the first page, plus a few dollars for each additional page. You also need to account for notary fees and certified mail postage.
Filing a lien yourself saves upfront service fees but exposes you to critical risks, such as invalidation and lawsuits, that a professional service eliminates.

A recorded claim is a temporary placeholder that lasts for exactly 6 months from the recording date. Contractors often believe a recorded document acts as a passive, permanent marker on the property title. They assume they can just wait for the owner to sell or refinance.
No. You generally cannot re-record an expired claim or unilaterally file an extension to buy more time for negotiations.
No. A mechanics lien is a highly specific type of property lien used exclusively by construction professionals. General property liens cover a much wider variety of debts.
| Feature | General Property Lien | Mechanics Lien |
|---|---|---|
| Definition | A broad claim on a property for unpaid debts. | A specific claim for unpaid construction work or materials. |
| Who Needs to File | Creditors, government agencies, or lenders. | Contractors, subcontractors, and suppliers. |
| Reason for Filing | Unpaid taxes, mortgage defaults, or court judgments. | Unpaid labor, materials, or equipment on a project. |
| Where to File | County Recorder or court system. | County Recorder where the property is located. |
| Deadlines | Varies widely by the type of debt. | 90 days from the last day of work. |
In Idaho, a mechanics lien is considered perfect or valid once it is properly recorded with the County Recorder’s office, but this must be done within 90 days of your last day of providing labor or materials to the project.
Start counting on the exact day after you last supplied meaningful labor or materials to the job site. Day 90 is your absolute final deadline to have the document officially recorded with the county. Do not count minor warranty work, equipment retrieval, or cosmetic touch-ups when calculating this date.
