Who this applies to
Oregon's limit follows retainage down every level of a job.
- Private construction and home improvement. An owner, a contractor and a subcontractor may each withhold as retainage at most 5% of the contract price of the work completed [1].
- Public improvements. A contracting agency may reserve retainage from any progress payment, up to 5% of that payment [2]. What a contractor or subcontractor withholds further down the same public job is governed by ORS 701.420, at the same 5% [2].
What the rule says
Private and public work share one ceiling, 5% [1] [2], but only the public statute provides a step-down as the work proceeds. After 50% of the work is completed, a contracting agency may eliminate retainage on the remaining monthly payments if, in its opinion, the work is progressing satisfactorily, on written application and with the surety's approval [2]; at 97.5% completion it may cut the amount retained to 100% of what the remaining work is worth [2]. Private retainage has no such step [1]. On public work the retainage is paid as part of the final payment [2], and on both sides interest on that final payment starts running 30 days after completion and acceptance of the work [1] [2].
How to comply
- Notice of completion. When the contractor considers the work complete, it notifies the party it is responsible to, and that party has 15 days to accept the work or identify the work still to be performed [1].
- Interest on a private final payment. The owner, contractor or subcontractor pays 1% per month on the final payment due, beginning 30 days after completion and acceptance, or 30 days after the 15-day period ends if the party does not respond, and running until final payment is tendered [1].
- Interest on a public final payment. The contracting agency pays 1.5% per month on the final payment, retainage included, from 30 days after completion and acceptance, with the same 15-day accept-or-notify step [2]. Progress payments other than retainage carry interest at three times the 90-day commercial paper discount rate, capped at 30 percent, starting 30 days after the invoice is received or 15 days after it is approved, whichever is earlier; the agency pays it automatically, without the contractor having to ask [2].
- Matching release when a subcontractor is paid. Within 15 days after notice that a subcontractor has been paid in full, the owner releases the matching retainage to the contractor [1].
- A bond instead of retainage. ORS 701.435 provides for a surety bond in lieu of retainage on large commercial structures and on public improvement contracts [1].
