Idaho Mechanic Lien Law Overview
Idaho construction mechanic lien rights are governed by Idaho General Statutes §45-501 to §45-517 et seq. This statutory framework protects the payment rights of general contractors, subcontractors, materialmen, and suppliers who furnish labor, services, or materials for the improvement of real property in the State of Idaho.
Idaho mechanic lien law provides a streamlined process for securing payment rights. No preliminary notice is required for any claimant type on private works projects, simplifying the initial compliance burden compared to many other states. However, strict adherence to mechanic lien filing and enforcement deadlines is essential. Contractors must comply with residential disclosure requirements under Idaho Statutes §45-525 (effective July 1, 2002), and all claimants must provide notice to the property owner by certified mail within 24 hours of recording a mechanic lien.
Idaho also provides separate payment bond claim procedures for public works projects under Idaho General Statutes §54-1925 to §54-1930, which require a minimum bond of 50% of the contract amount. Where the bond exceeds 50%, retainage on public works cannot exceed 5%. On private works, retainage cannot exceed 5%, and final release of retainage may be conditioned upon delivery of mechanic lien waivers from all potential claimants.
