Filing deadline

Claim of Lien recorded with the county recorder where the property (or part of it) lies within 90 days (a day-count, not 3 months) after completion or cessation of the claimant's labor, services, or material furnishing; substantial completion controls, and trivial punch-list or warranty work does not extend the clock, though repairs demanded by a public inspector can; no residential/commercial deadline difference.

Notice prerequisites

No pre-work notice from any claimant tier. Exception: on residential construction/remodel contracts over $2,000, the general contractor must give the homeowner or purchaser a written Residential Disclosure (rights to lien waivers, insurance proof, title insurance, surety bond; list of subs/suppliers/equipment lessors over $500) before closing or final payment; noncompliance is a Consumer Protection Act violation ($500 per violation or actual damages, possible fees and punitives). It affects the GC's exposure, not lien perfection by subs.

Service on the owner

A copy of the recorded Claim of Lien itself (not a separate notice) must be delivered personally to the owner or reputed owner, or sent certified mail to the owner's last known address, within 5 business days after recording (I.C. § 45-507(5)); filing precedes service.

Enforcement

Foreclosure suit in district court of the county where the land lies within 6 months of recording the lien or it expires; the 6 months can restart from a payment on account or an endorsed extension of credit noted on the lien record; a foreclosure judgment lien lasts 5 years; no lis pendens requirement mentioned.

I.C. §§ 45-501 through 45-525, esp. §§ 45-507, 45-510, 45-512; I.C. § 45-525 (residential disclosure)
