Frequently Asked Questions
Iowa residential projects have a 30-day lien deadline
If you're working on an owner-occupied home in Iowa, your lien window is 30 days from last furnishing — not 90. Mark this on your calendar at project start.
Serve Iowa commencement notices in the first 30 days
Iowa's preliminary notice requirement for residential work must be served within the first 30 days of furnishing. Miss it and you may lose your lien rights on the project.
In Iowa, a mechanic's lien must be filed within 90 days of last furnishing labor or materials (30 days for owner-occupied residential). An action to enforce must be filed within 2 years of the lien filing.
Iowa requires subcontractors and suppliers to serve a 'commencement of work' notice to the owner and GC within the first 30 days of work on certain projects. Failure to provide this notice can eliminate lien rights on residential projects.
Iowa Code §572.8 requires that liens on owner-occupied residential properties be filed within 30 days of last furnishing — much shorter than the standard 90-day commercial deadline. Residential projects require faster action.
