Iowa Construction Lien FAQ

The filing deadline of an Iowa Mechanic's Lien is 90 days from the last date of furnishing labor, materials, equipment, or professional services.

Yes, on residential projects only. Iowa requires subcontractors, suppliers, and other parties who do not have a direct contract with the homeowner to send a Notice to Owner within 10 days of first furnishing labor or materials. This notice alerts the homeowner that lower-tier parties are involved and may later assert lien rights if unpaid.

Iowa grants mechanics lien rights to:

• General contractors

• Subcontractors

• Sub-subcontractors

• Material suppliers

• Equipment rental companies

• Laborers

• Architects, engineers, surveyors, and other design professionals

Lien rights apply to private construction projects. Public projects require bond claims.

If you miss the Iowa mechanics lien deadline, you permanently lose your right to file and enforce a lien for that work.

Iowa mechanics lien must be recorded with the County Recorder in the county where the property is located.

The filing deadline of an Iowa Mechanics Lien is within 90 days of the claimant’s last date of furnishing labor, materials, equipment, or professional services. This deadline is strictly enforced, and missing it results in a complete loss of Iowa mechanics lien rights.

You must include the following in an Iowa Mechancis Lien form:

• Claimant’s legal name and address (you)

• Property owner’s name

• Hiring party’s name

• Legal property description

• Description of labor, materials, or services

• Amount claimed as unpaid

• Date of last furnishing

• Claimant’s signature and verification

No. Iowa does not impose a minimum or maximum dollar amount for mechanics liens. A lien may be filed for any unpaid amount owed for labor, materials, equipment, or professional services that improved the property.

However, the lien must reflect only the amount actually due after all credits and payments. Overstating the lien amount, whether intentional or careless, can expose the claimant to damages or invalidate the lien.

Yes. Iowa law allows multiple contractors, subcontractors, suppliers, or design professionals to file separate mechanics liens against the same property if they independently performed work or supplied materials and were not paid.

Each Iowa lien stands on its own and is evaluated based on compliance with Iowa’s notice, filing, service, and enforcement requirements.

If the customer pays you the full amount owed after you have recorded a lien, you have a legal obligation to formally clear the lien from the property records.

You must prepare and file an Iowa Discharge of Lien (or Release of Lien) with the same office where the original lien was recorded.
