Iowa Mechanics' Notice and Lien Registry (MNLR)

In Iowa, securing mechanics lien rights on residential properties requires interacting with the state's online portal. Under Iowa Code § 572.13A, general contractors must post a Notice of Commencement to the MNLR within 10 days of starting work. Subcontractors must post a Preliminary Notice to the MNLR to protect their rights.

Because these deadlines start ticking on your first day on the job site, establishing a concrete timeline is critical. MyCrewTracker assists Iowa contractors by using Daily Reports to create a verifiable, date-stamped record of when work commenced, ensuring your back office accurately tracks the 10-day window.

Iowa Public Works Retainage

Under Iowa Code § 573.12, Iowa law caps the retainage that can be withheld on public improvement contracts at 5% of the approved estimates.

To enforce these rights, contractors must maintain perfect documentation of when invoices were transmitted and received. MyCrewTracker offers a secure cloud repository where Iowa contractors can organize dated payment applications and formal communications.
