What a conditional lien waiver holds up in a draw package
A conditional lien waiver is a document a contractor or subcontractor signs, giving up their right to file a mechanic's lien on a project once the payment clears, not before. It's the most common waiver attached to a draw package, and it's also the one most likely to sit in a reviewer's inbox for an extra week while someone figures out whether the condition has been met.
The logic behind it is sound. A sub doesn't want to sign away lien rights before money is in the bank, in case the check bounces or the draw gets pulled. So the waiver says, in effect, "this release is good once payment clears, not before." That protects the sub. It also means the owner or lender holding the draw request now has a document whose validity depends on a future event they have to track separately.
Conditional vs. unconditional lien waiver
The difference comes down to timing, not amount. A conditional waiver releases lien rights contingent on the payment clearing. An unconditional waiver releases them outright, no contingency, signed after the fact once the contractor confirms funds landed.
Draw packages lean on conditional waivers because they're submitted alongside the payment application, before the money has moved. You can't ask for an unconditional waiver on a payment that hasn't happened yet; nobody would sign it. So the typical flow is conditional waiver in, funds released, unconditional waiver collected afterward to close the loop. On a job with a dozen subs and a monthly draw cycle, that means two waivers per sub per period, and a reviewer tracking which conditional waivers still need their unconditional follow-up from last month.
Why the waiver holds up the draw
The waiver itself rarely causes a delay. What causes the delay is reconciling it against everything else in the package. A conditional waiver for $340,000 in drywall work only means something if it lines up with the pay application for that same amount, the schedule of values, and some evidence that $340,000 of drywall is in the building. If the waiver amount doesn't match the pencil-draw percentage, or the schedule of values has been revised since the last draw and nobody flagged it, the reviewer has to stop and chase an explanation before signing off.
Lenders in particular treat this as a control point. A waiver that's internally consistent with the draw request, but disconnected from anything observed in the field, still only tells you what the contractor says was done. The waiver confirms the lien release. It says nothing about the work itself, and the two get conflated more often than they should. Those are two different claims, and conflating them is how draws get approved against percentages that don't hold up later.
That's the gap a weekly observed record is built to close. A project that pairs each draw with a site-wide capture, measured against the schedule rather than against the contractor's own line items, gives the reviewer something to check the waiver and pay app against before money moves, not after a dispute shows up. Construction Progress builds that record from weekly drone flights mapped to the project schedule, giving the percent-complete sitting next to the lien waivers in the draw package a field-level basis instead of a self-report alone.
What to flag before the draw goes out
A few things worth checking every cycle, regardless of how clean the paperwork looks:
- Does the conditional waiver amount match the current pay application line, not last month's?
- Is there an outstanding unconditional waiver from the prior draw that hasn't come back yet?
- Does the claimed percentage on the schedule of values match what you can see happened on site this period?
None of these questions get answered by reading the waiver more carefully. They get answered by having a separate, observed check on progress that doesn't depend on the contractor's own paperwork being internally consistent. The waiver protects lien rights. It was never meant to verify percent-complete, and treating it as a stand-in for that is usually where the holdup starts.
If your draw reviews keep stalling on whether the paperwork matches what's actually built, it might be worth putting an observed progress map next to the waivers before the next request goes out.
