1. Scope of Work
Subcontractor shall furnish all labor, tools, equipment, and materials necessary to complete the agreed scope of work in a good and workmanlike manner, in compliance with all applicable building codes.
2. Payment
GC shall pay Subcontractor within 10 days after receiving payment from the Project Owner. Under Iowa Code § 572.15, the general contractor must pay subcontractors within 15 days after receiving payment from the owner, or within 30 days of the sub’s invoice if the owner has not paid, subject to good-faith disputes. Late amounts accrue interest at 2% per month.
3. Retainage
GC may withhold 10% retainage from each progress payment. Iowa does not cap retainage by statute on private construction; retainage is a matter of contract negotiation.
4. Lien Waivers
Iowa does not require statutory lien waivers; waivers are enforceable if they clearly identify the project, amount, and date. Under Iowa Code § 572.2, lien rights are preserved unless payment is actually received and the waiver is conditional.
5. Mechanics Lien Rights Preserved
Iowa requires filing a lien within 90 days after the last work or materials were furnished, followed by foreclosure within 2 years. Iowa does not require a statutory preliminary notice for private projects; best practice is a voluntary Notice of Intent to Lien sent promptly after first furnishing labor or materials.
6. Indemnification
Iowa under Iowa Code § 572.19 voids construction contract provisions requiring a subcontractor to indemnify or hold harmless another party for that party’s sole negligence or willful misconduct.
7. Governing Law
This Agreement is governed by the laws of the State of Iowa, including Iowa Code Chapter 572 (Iowa Lien Law) and Prompt Payment provisions at Iowa Code § 572.15 et seq..

Iowa does not require a statutory preliminary notice for private projects; best practice is a voluntary Notice of Intent to Lien sent promptly after first furnishing labor or materials.

Iowa Subcontractor Agreement FAQs
When must a general contractor pay me under Iowa prompt payment law?
Under Iowa Code § 572.15, the general contractor must pay subcontractors within 15 days after receiving payment from the owner, or within 30 days of the sub’s invoice if the owner has not paid, subject to good-faith disputes. Late amounts accrue interest at 2% per month. Your subcontract should mirror these statutory deadlines so that late payments automatically trigger the statutory interest and remedies without negotiation.
How much retainage can a GC legally withhold in Iowa?
Iowa does not cap retainage by statute on private construction; retainage is a matter of contract negotiation. Your agreement should specify the exact retainage percentage, the release schedule (typically at substantial completion and final completion), and payment of statutory interest on withheld retainage.
Are pay-if-paid clauses enforceable in Iowa subcontracts?
While Iowa has not enacted a blanket statutory ban on pay-if-paid clauses, courts and statutes in most states treat "pay-when-paid" as a reasonable timing provision rather than an absolute condition. Check Iowa Code Chapter 572 (Iowa Lien Law) and Prompt Payment provisions at Iowa Code § 572.15 et seq. for specific restrictions, and make sure your subcontract states that payment from the owner is not an absolute condition precedent to your right to be paid.
What lien waiver rules apply in Iowa?
Iowa does not require statutory lien waivers; waivers are enforceable if they clearly identify the project, amount, and date. Under Iowa Code § 572.2, lien rights are preserved unless payment is actually received and the waiver is conditional. Never sign an unconditional waiver until payment has actually cleared your bank account, and make sure your waiver identifies the specific billing period and amounts to avoid losing lien rights on future work.
Can a Iowa subcontract require me to indemnify the GC for the GC’s own negligence?
Iowa under Iowa Code § 572.19 voids construction contract provisions requiring a subcontractor to indemnify or hold harmless another party for that party’s sole negligence or willful misconduct. Always read the indemnification clause carefully — even in states with anti-indemnity statutes, "broad form" indemnity for joint negligence is typically still enforceable.
How do I preserve my mechanics lien rights in Iowa?
Iowa requires filing a lien within 90 days after the last work or materials were furnished, followed by foreclosure within 2 years. Iowa does not require a statutory preliminary notice for private projects; best practice is a voluntary Notice of Intent to Lien sent promptly after first furnishing labor or materials. Send statutory notices by certified mail or another trackable method, keep copies of everything, and calendar the deadlines immediately upon each project’s completion.
