Who and what this applies to
State-procurement construction under §11-35-3030(4); separately, covered Chapter 29-6 contracts.
Thresholds and scope
State progress-payment retainage may not exceed 3.5%; Chapter 29-6 separately permits a reasonable retainage amount within its scope/exclusions.
The rules
- Section 11-35-3030(4) caps state construction installment retainage at 3.5%. Each prime/subcontract division is treated separately; certified completed divisions’ retained funds are released forthwith to the prime and within 10 days after prime receipt to the responsible subcontractor. Source
- Section 29-6-40 permits reasonable retainage; §29-6-60 excludes residential homebuilders, 16-or-fewer-unit residential improvements and private owners of improvements not financed by a nonowner. Do not apply the state-procurement cap indiscriminately to private contracts. Source
