Private Works — Preliminary Notice Not Required (§45-507)
Idaho law does not require any preliminary notice from any claimant type — including general contractors, subcontractors, and material suppliers — as a prerequisite to filing a Mechanic's Lien on private construction projects. This is a significant advantage compared to many other states that impose strict preliminary notice deadlines.
While no preliminary notice is required, claimants should maintain thorough documentation of all labor performed, materials furnished, and amounts owed. Proper record-keeping from the start of the project is essential to supporting any future Claim of Mechanic Lien.
Contractor Disclosure to Residential Property Owners (§45-525)
Under Idaho Statutes §45-525 (effective July 1, 2002), contractors on residential projects must provide a written disclosure to the property owner or buyer. This disclosure requirement is separate from the mechanic lien filing process but is an important compliance obligation for contractors working on residential construction in Idaho.
The disclosure must inform the residential property owner about the contractor's rights and the potential for mechanic liens to be filed on the property by subcontractors and suppliers. Failure to comply with this disclosure requirement may have consequences for the contractor's ability to enforce certain rights.
24-Hour Certified Mail Notice Upon Mechanic Lien Recording (§45-507)
While Idaho does not require a preliminary notice, it does require all claimants to give notice to the property owner by certified mail within 24 hours of recording the Claim of Mechanic Lien. This post-recording notice requirement applies to all claimant types — general contractors, subcontractors, and material suppliers alike. Idaho Statute §45-507, as revised effective July 1, 2002.
Failure to provide this certified mail notice within the 24-hour window may affect the enforceability of the mechanic lien. Claimants should prepare the certified mail notice in advance so it can be sent immediately upon recording the mechanic lien.
Public Works — Subcontractor Notice Requirements (§54-1925 to §54-1930)
On Idaho public works projects, first-tier subcontractors who are in direct privity with the bonded prime contractor are not required to serve any preliminary notice as a condition of their right to make a claim against the payment bond.
However, first-tier subcontractors must meet the timing requirements for filing suit: not less than 90 days from last performance and not more than 1 year after final payment was due under the subcontract. No additional notice to the bonded contractor is required for first-tier subcontractors.
Public Works — Third-Tier Notice of Claim on Bond (§54-1927)
Third-tier subcontractors and material suppliers who are not in direct privity with the bonded prime contractor must serve a written Notice of Claim on the bonded contractor within 90 days from the date of last performance of labor or furnishing of materials. This notice must be provided to preserve the right to make a claim against the payment bond under Idaho Statute §54-1927.
Failure to serve this 90-day Notice of Claim within the statutory deadline will result in the loss of the right to make a claim against the payment bond. The notice should identify the claimant, the amount claimed, and the nature of the labor or materials furnished.
