Iowa Retainage Guide and FAQs

Iowa does not provide a retainage statute for private projects.

1. Retention. Payments made under contracts for the construction of public improvements, unless provided otherwise by law, shall be made on the basis of monthly estimates of labor performed and material delivered, as determined by the project architect or engineer. The public corporation shall retain from each monthly payment not more than five percent of that amount which is determined to be due according to the estimate of the architect or engineer. The contractor may retain from each payment to a subcontractor not more than the lesser of five percent or the amount specified in the contract between the contractor and the subcontractor.

2. Prompt payment.

a.

(1) Interest shall be paid to the contractor on any progress payment that is approved as payable by the public corporation’s project architect or engineer and remains unpaid for a period of fourteen days after receipt of the payment request at the place, or by the person, designated in the contract, or by the public corporation to first receive the request, or for a time period greater than fourteen days, unless a time period greater than fourteen days is specified in the contract documents, not to exceed thirty days, to afford the public corporation a reasonable opportunity to inspect the work and to determine the adequacy of the contractor’s performance under the contract.

(2) Interest shall accrue during the period commencing the day after the expiration of the period defined in subparagraph (1) and ending on the date of payment. The rate of interest shall be determined as set forth in section 573.14.

b. A progress payment or final payment to a subcontractor for satisfactory performance of the subcontractor’s work shall be made no later than one of the following, as applicable:

(1) Seven days after the contractor receives payment for that subcontractor’s work.

(2) A reasonable time after the contractor could have received payment for the subcontractor’s work, if the reason for nonpayment is not the subcontractor’s fault. A contractor’s acceptance of payment for one subcontractor’s work is not a waiver of claims, and does not prejudice the rights of the contractor, as to any other claim related to the contract or project.

3. Interest payments.

a. If the contractor receives an interest payment under section 573.14, the contractor shall pay the subcontractor a share of the interest payment proportional to the payment for that subcontractor’s work.

b. If a public corporation other than a school corporation, county, or city retains funds, the interest earned on those funds shall be payable at the time of final payment on the contract in accordance with the schedule and exemptions specified by the public corporation in its administrative rules. The rate of interest shall be determined by the period of time during which interest accrues, and shall be the same as the rate of interest that is in effect under section 12C.6 as of the day interest begins to accrue.

A public corporation shall not be permitted to plead noncompliance with section 573.12 and the retained percentage of the contract price, which in no case shall be more than five percent, constitutes a fund for the payment of claims for materials furnished and labor performed on the improvement and shall be held and disposed of by the public corporation as provided in this chapter.

1. The fund provided for in section 573.13 shall be retained by the public corporation for a period of thirty days after the completion and final acceptance of the improvement. If at the end of the thirty-day period claims are on file, the public corporation shall continue to retain from the unpaid funds a sum equal to double the total amount of all claims on file. The remaining balance of the unpaid fund, or if no claims are on file, the entire unpaid fund, shall be released and paid to the contractor.

2. The public corporation shall order payment of any amount due the contractor to be made in accordance with the terms of the contract. Except as provided in section 573.12 for progress payments, failure to make payment pursuant to this section, of any amount due the contractor, within forty days, unless a greater time period not to exceed fifty days is specified in the contract documents, after the work under the contract has been completed and if the work has been accepted and all required materials, certifications, and other documentations required to be submitted by the contractor and specified by the contract have been furnished the awarding public corporation by the contractor, shall cause interest to accrue on the amount unpaid to the benefit of the unpaid party. Interest shall accrue during the period commencing the thirty-first day following the completion of work and satisfaction of the other requirements of this subsection and ending on the date of payment. The rate of interest shall be determined by the period of time during which interest accrues, and shall be the same as the rate of interest that is in effect under section 12C.6, as of the day interest begins to accrue, for a deposit of public funds for a comparable period of time. However, for institutions governed pursuant to chapter 262, the rate of interest shall be determined by the period of time during which interest accrues, and shall be calculated as the prime rate plus one percent per year as of the day interest begins to accrue. This subsection does not abridge any of the rights set forth in section 573.16. Except as provided in sections 573.12 and 573.16, interest shall not accrue on funds retained by the public corporation to satisfy the provisions of this section regarding claims on file. This chapter does not apply if the public corporation has entered into a contract with the federal government or accepted a federal grant which is governed by federal law or rules that are contrary to the provisions of this chapter. For purposes of this subsection, “prime rate” means the prime rate charged by banks on short-term business loans, as determined by the board of governors of the federal reserve system and published in the federal reserve bulletin.

1. A person, firm, or corporation that has performed labor for or furnished materials, service, or transportation to a subcontractor shall not be entitled to a claim against the retainage or bond under this chapter unless the person, firm, or corporation that performed the labor or furnished the materials, service, or transportation does all of the following:

a. Notifies the principal contractor in writing with a one-time notice containing the name, mailing address, and telephone number of the person, firm, or corporation that performed the labor or furnished the materials, service, or transportation, and the name of the subcontractor for whom the labor was performed or the materials, service, or transportation were furnished, within thirty days of first performing the labor or furnishing the materials, service, or transportation for which a claim may be made. Additional labor performed or materials, service, or transportation furnished by the same person, firm, or corporation to the same subcontractor for use in the same construction project shall be covered by this notice.

b. Supports the claim with a certified statement that the principal contractor received the notice described in paragraph “a”.

2. This section shall not apply to highway, bridge, or culvert projects as referred to in section 573.28.

Notwithstanding section 573.14, a public corporation may release retained funds upon completion of ninety-five percent of the contract in accordance with the following:

1. Any person, firm, or corporation who has, under contract with the principal contractor or with subcontractors, performed labor, or furnished materials, service, or transportation, in the construction of the public improvement, may file with the public corporation an itemized, sworn, written statement of the claim for the labor, or materials, service, or transportation. The claim shall be filed with the public corporation either before the expiration of the thirty days after completion of ninety-five percent of the contract or at any time after the thirty-day period if the public corporation has not paid the full contract price and no action is pending to adjudicate rights in and to the unpaid portion of the contract price.

2. The fund, as provided in section 573.13, shall be retained by the public corporation for a period of thirty days after ninety-five percent of the contract has been completed. If at the end of the thirty-day period, a claim has been filed, in accordance with this section, the public corporation shall continue to retain from the unpaid funds, a sum equal to double the total amount of all claims on file. The remaining balance of the unpaid fund, or if there are no claims on file, the entire unpaid fund, may be released and paid to the contractor.

3. The public corporation, the principal contractor, or any claimant for labor or materials, service, or transportation, who has filed a claim or the surety on any bond given for performance of the contract, at any time after the expiration of thirty days, and not later than sixty days after the completion of ninety-five percent of the contract, may bring an action in equity in the county where the public improvement is located to determine rights to moneys contained in the fund or to enforce liability on the bond. The action shall be brought in accordance with sections 573.16 through 573.18, with the completion of ninety-five percent of the contract taking the place of the date of final acceptance.

4. A public corporation that releases funds at the completion of ninety-five percent of the contract, in accordance with this section, shall not be required to retain additional funds.

The public corporation, the principal contractor, any claimant for labor or material who has filed a claim, or the surety on any bond given for the performance of the contract, may, at any time after the expiration of thirty days, and not later than sixty days, following the completion and final acceptance of said improvement, bring action in equity in the county where the improvement is located to adjudicate all rights to said fund, or to enforce liability on said bond.

Upon written demand of the contractor served, in the manner prescribed for original notices, on the person filing a claim, requiring the claimant to commence action in court to enforce the claim, an action shall be commenced within thirty days, otherwise the retained and unpaid funds due the contractor shall be released. Unpaid funds shall be paid to the contractor within twenty days of the receipt by the public corporation of the release as determined pursuant to this section. Failure to make payment by that date shall cause interest to accrue on the unpaid amount. Interest shall accrue during the period commencing the twenty-first day after the date of release and ending on the date of the payment. The rate of interest shall be determined pursuant to section 573.14. After an action is commenced, upon the general contractor filing with the public corporation or person withholding the funds, a surety bond in double the amount of the claim in controversy, conditioned to pay any final judgment rendered for the claims so filed, the public corporation or person shall pay to the contractor the amount of funds withheld.
