Iowa mechanic's liens

Who and what this applies to

Mechanics’ Notice and Lien Registry posting under Iowa Code §§572.8–.11; residential and lower-tier notices remain separate statutory prerequisites.

The rules

• Section 572.8 requires a verified statement of account in the state Mechanics’ Notice and Lien Registry, with the credited amount, furnishing dates, property description and owner information. Source
• Section 572.9 permits posting within two years and 90 days after last furnishing, but posting more than 90 days after last furnishing invokes §572.10’s owner-service requirement and §572.11’s limits tied to the unpaid owner balance, subject to the separate bond rule. The outer period should not be treated as equivalent to timely posting within 90 days. Source
• Residential construction has the owner-notice and registry provisions in §§572.13–.13B. On commercial construction, §572.33 imposes a 30-day first-furnishing notice on persons supplying a subcontractor. Source
