How to File a Mechanics Lien in Iowa
Step 1 — Confirm you have lien rights in Iowa
Iowa's recorded rules cover general contractors, subcontractors and suppliers (Iowa Code § 572.13A). Each of those roles has its own filing window — see Step 3. Iowa rule detail: Sub/supplier should serve preliminary notice on owner and GC within 30 days of first furnishing to preserve full lien rights.
Step 2 — Send the Iowa preliminary notice
Iowa requires a preliminary notice Post to MNLR, mechanics notice registry (Iowa Code § 572.8). It is a precondition, not a formality. It must reach County Recorder and Owner and GC and Prime Contractor and Surety and Prime Contractor. Delivery: Certified Mail, Return Receipt Requested. Iowa rule detail: File mechanic's lien within 90 days of last furnishing of labor or materials.
Step 3 — Your Iowa filing deadline
Iowa sets the window by claimant role: • General contractors: within 90 days of your last day of work or materials. • Subcontractors and suppliers: within 90 days of your last day of work or materials. The clock runs from last date of furnishing (post-90) — not your invoice date. Punch-list and warranty callbacks generally do not restart it. Iowa rule detail: File mechanic's lien within 90 days of last furnishing.
Step 4 — Prepare and record the lien in Iowa
Record in the county where the property sits, under Iowa Code § 572.14. The document must identify the property, the owner of record, the amount actually owed, and what you furnished. Overstating the amount can void the claim outright. Iowa rule detail: File suit to enforce lien within 2 years of recording.
Step 5 — Serve the recorded Iowa lien
Iowa requires service on County Recorder and Owner and GC and Prime Contractor and Surety and Prime Contractor. Use Certified Mail, Return Receipt Requested and keep the receipt. In many states an unserved lien is unenforceable even though it appears on title. Iowa rule detail: Written notice within 30 days of last furnishing on public works projects. No lien on public property in Iowa.
Step 6 — Enforce before the Iowa deadline expires
You must sue to foreclose within 2 years (filing) (Iowa Code § 573.16). Miss it and the lien expires and title clears, leaving only a contract claim. Iowa rule detail: File suit on payment bond within 1 year of last furnishing on public projects.
Retainage rules that affect your Iowa claim
Iowa treats retainage on its own schedule (Iowa Code § 573.12), so money still held back may have a different due date than your progress billings. Iowa rule detail: Second-tier claimants only. No notice = no bond claim.
Other Iowa requirements that void liens
• File no sooner than 90 days AND no later than 1 year. • Public: prime must pay sub within 30 days of receiving payment. Private: interest accrues at 10%/year after 30 days past due. • Public retainage released within 30 days after final completion and acceptance. 5% maximum retainage on public contracts.
Frequently Asked Questions
How long do I have to file a mechanics lien in Iowa?
Iowa requires the lien to be recorded within 90 days, measured from last date of furnishing (post-90). The exact window depends on your role — general contractors: within 90 days of your last day of work or materials.
Do I need to send a preliminary notice before filing in Iowa?
Yes. Iowa requires a preliminary notice Post to MNLR (mechanics notice registry). Failing to send it on time generally forfeits your lien rights entirely, regardless of how much you are owed.
Where do I file a mechanics lien in Iowa?
File with the county recorder's office in the county where the property is located. Filing in the wrong county does not preserve your deadline, and re-filing in the correct county after the deadline will not save the claim.
What happens if I miss the Iowa filing deadline?
Your lien rights are extinguished. Iowa courts do not grant extensions for missed mechanics lien deadlines. You would be left with a breach-of-contract claim against whoever hired you, which carries no security interest in the property and is far harder to collect.
How long does a mechanics lien last in Iowa?
Once recorded, you must file suit to enforce within 2 years (filing). If you do not, the lien expires automatically and no longer clouds the property's title.
