Iowa prompt payment

Who and what this applies to

Public improvements governed by Iowa Code chapter 573; the current 2026 codification incorporates 2025 Acts chapter 29.

The rules

• Section 573.12 provides monthly payment on the architect’s or engineer’s estimate. For a progress payment approved as payable, interest ordinarily applies after 14 days from receipt of the request at the designated place or by the designated recipient. Contract documents may extend that interval to no more than 30 days to allow inspection and review. Source
• The contractor passes the corresponding amounts to subcontractors within seven days after receipt, or within a reasonable time after it could have received payment if the delay is not attributable to the subcontractor, as specified in §573.12. Source
