Idaho Lien Law Deadlines for Suppliers and Subcontractors
Idaho gives suppliers and subcontractors 90 days after their last furnishing to record a lien, 5 business days after recording to serve the owner, and 6 months after recording to sue. Idaho requires no preliminary notice.
Public date calculations cover Florida and Kansas. Idaho dates require qualified review.
Risk context
Idaho is High Risk for Suppliers
Idaho has no preliminary notice, which makes it easy to overlook the steps that do matter. The lien must be recorded within 90 days of your last furnishing, a copy must be served on the owner within 5 business days after recording, and suit must be filed within 6 months. Each step runs on its own clock.

Supplier pitfalls
Common Supplier Mistakes in Idaho
Missing the 5-business-day service deadline
Recording the lien is only half of the filing step. A copy has to be served on the owner within 5 business days after recording, by certified mail or through an officer authorized to serve process. Plan service for the same day you record.
Counting from the invoice date
Idaho's 90 days run from the day you last furnished materials or finished your work, not from the invoice or payment due date. Keep delivery tickets that show the last furnishing date.
Letting the 6-month suit deadline pass
Unless you file suit within 6 months after recording, the lien stops binding the property. A payment on account or credit extension noted on the lien record changes the start of that count.
