Private Works — 6-Month Suit Deadline
Under Idaho law, a mechanic lien claimant must file suit to foreclose the Mechanic's Lien within 6 months after the date the Claim of Mechanic Lien was filed (recorded). This deadline applies to all claimant types — general contractors, subcontractors, and material suppliers alike.
Failure to commence suit within the 6-month period will result in the automatic expiration of the mechanic lien. The mechanic lien will no longer encumber the property, and the claimant will lose the security interest. Prompt action is essential once a Claim of Mechanic Lien has been recorded to ensure the claimant preserves the right to enforce the mechanic lien through foreclosure.
Public Works — Subcontractor Bond Claim Suit Deadline (§54-1925)
On Idaho public works projects, first-tier subcontractors who are in direct privity with the bonded prime contractor must file suit on the payment bond not less than 90 days from the date of last performance of labor or furnishing of materials, and not more than 1 year after final payment was due under the subcontract. No preliminary notice is required for first-tier subcontractors.
The 90-day waiting period before suit can be filed is designed to allow time for payment disputes to be resolved before litigation. However, the 1-year outer deadline is strict, and failure to file within 1 year of the date final payment was due under the subcontract will bar the claim.
Public Works — Third-Tier Bond Claim Suit Deadline (§54-1927)
Third-tier subcontractors and material suppliers who are not in direct privity with the bonded prime contractor must file suit on the payment bond not less than 90 days and not more than 1 year after the date of last performance of labor or furnishing of materials. §54-1927.
Unlike first-tier subcontractors, third-tier claimants must also have served a written Notice of Claim on the bonded contractor within 90 days from the date of last performance as a prerequisite to filing suit. Failure to serve the Notice of Claim within the 90-day notice period will forfeit the right to claim against the payment bond.
Public Works — Payment Bond Requirements (§54-1925)
Idaho law requires a payment bond on public works projects with a minimum amount of 50% of the contract price. Where the bond amount exceeds 50% of the contract, retainage on the public works project cannot exceed 5%. Idaho General Statutes §54-1925 to §54-1930.
The payment bond is the sole security mechanism available to unpaid subcontractors and suppliers on public works projects, as Mechanic's Liens cannot be filed against public property. All claimants on public works projects should verify that a payment bond is in place and should file claims against the bond within the statutory deadlines.
No Mechanic's Lien on Public Property
As with all states, Idaho does not permit the filing of Mechanic's Liens on public property. Subcontractors and material suppliers working on public works projects must rely on the payment bond required under Idaho General Statutes §54-1925 to §54-1930 as their remedy for non-payment.
Claimants on public works projects should ensure they understand and comply with the applicable notice and suit filing deadlines to preserve their bond claim rights. National Lien & Bond assists claimants in navigating these requirements to maximize recovery on public works projects.
