Mechanic's Liens in Idaho

In Idaho, a mechanics lien must be recorded with the county recorder within 90 days of completion or cessation of work or delivery of materials. The lien must be verified and include the amount due (after credits), property description, and owner/employer name. For residential projects, a disclosure per Idaho Code § 45-525 must also be attached. A true copy of the lien must be served on the property owner within 5 business days of filing. A foreclosure action must be initiated within 6 months of filing the lien, along with a lis pendens. Prevailing parties may recover attorney fees.

Bond Claims in Idaho

On public projects, mechanic's lien rights are typically replaced by bond claim rights. Bond claim notice and enforcement timelines can vary by project type and bond language, so coordinate with your construction attorney to confirm the correct deadline and required notice path.
