Iowa does not require a notice of intent before recording a lien, but sending one is often what gets the invoice paid.

Recording and enforcing an Iowa lien

Recording the lien

Record with the county recorder where the property sits. Electronic recording is available in participating counties. No notary is required on the lien itself. The lien claim must be verified by the claimant.

After recording

A copy of the recorded lien must be served on the property owner promptly after recording. To keep the lien alive it must be enforced by lawsuit within 820 days after last furnishing labor or materials.

Wrongful lien exposure

Iowa exposes claimants who file an exaggerated or baseless lien to damages. On residential property, a person who successfully challenges a lien may be awarded attorney fees and actual damages; if the lien was posted in bad faith or the supporting affidavit was materially false, the court must award the owner attorney fees plus not less than $500 or the lien amount, whichever is less (§ 572.32(2), amended 2021). Posting fictitious, forged or false information to the registry also carries an administrative penalty set by rule (§ 572.34(4)).

Practitioner notes for Iowa

Iowa liens and notices are not recorded at the county. They are posted to the Mechanics' Notice and Lien Registry run by the Secretary of State, online or by mail (Iowa Code §§ 572.8, 572.34). On residential jobs, a general contractor that uses subcontractors must give the owner the statutory notice and post a notice of commencement within 10 days after work begins, or it loses its lien (Iowa Code §§ 572.13, 572.13A). Each subcontractor and supplier below the general contractor must post a preliminary notice to the registry. A lien reaches only what the owner still owed the general contractor when the notice was posted and received, so post early (Iowa Code § 572.13B). On commercial jobs, anyone furnishing to a subcontractor must send the general contractor a one-time written notice within 30 days after first furnishing (Iowa Code § 572.33). A verified lien statement posted within 90 days after last furnishing gets full protection. A lien can still be posted up to two years and 90 days after last furnishing, but late liens require notice to the owner and reach only the unpaid balance (Iowa Code §§ 572.9-572.11). A suit to enforce must be filed within two years after the 90-day period ends, or within 30 days after an owner's written demand (Iowa Code §§ 572.27, 572.28). On homes, a lien posted in bad faith or with a materially false affidavit costs the claimant the owner's attorney fees plus at least $500, or the lien amount if that is less (Iowa Code § 572.32). How the residential notice limits apply to a given payment history can be fact-specific, so confirm with counsel.
