Punch List
A punch list is a list of incomplete or defective items a contractor must finish or correct before final payment, generated at substantial completion. The architect or owner records each nonconforming item during a walkthrough, and the contractor cures the list to reach final completion and release the remaining retainage.
How a Punch List Works
A punch list is generated at substantial completion, the milestone where the owner can occupy the space even though minor work remains. The architect inspects the project, the contractor prepares the list, and the architect verifies and amends it before both parties sign the AIA G704 Certificate of Substantial Completion.
Under AIA Document G704-2017, the contractor drafts the list of items to be completed or corrected, the architect confirms the work is substantially complete, and the itemized list is attached to the certificate and accepted by the owner and contractor. Signing the certificate starts warranty periods, transfers occupancy and insurance responsibility, and sets the contractor's path to final payment.
The punch list ties directly to money held back. Owners commonly release most of the retainage at substantial completion but continue to withhold an amount against the open list until every item is cured. Once the architect confirms each item is corrected, the contractor submits final documentation, the owner releases the balance, and the project reaches final completion.
Why a Punch List Matters
A punch list matters because it is the last contractual leverage the owner holds before releasing final payment. Until items are cured, the owner can withhold retainage against them, so a poorly documented list either releases cash too early or traps a contractor's margin over cosmetic disputes. Precision at closeout protects both sides.
For an operator underwriting or asset-managing a development, the punch list is a schedule and cash-flow event, not paperwork. A list that lingers delays retainage release, pushes back lender draws tied to completion, and can hold up the certificate of occupancy that a tenant's lease commencement depends on. Law firm Cox Castle notes that punch list holdbacks are among the most disputed mechanics at closeout, because the parties negotiate both the dollar amount withheld and when it is earned back.
The defensible rule of thumb: an item belongs on the punch list only if it is minor enough that its incompleteness does not prevent the owner from using the space. Anything that blocks occupancy is not a punch item, it is a barrier to substantial completion itself.
Example
A punch list on a small office fit-out typically holds back retainage against a handful of unfinished or defective items until each is cured. The table below shows five representative items, the party responsible for the fix, and the dollar amount of retainage withheld against each until the architect signs off.
Punch item | Responsibility | Retainage held until cured |
|---|---|---|
Chipped drywall in lobby | General contractor | $1,200 |
HVAC balancing report missing | Mechanical sub | $3,000 |
Three interior doors misaligned | Carpentry sub | $900 |
Missing outlet covers, 12 rooms | Electrical sub | $600 |
Touch-up paint, stairwell | Painting sub | $800 |
The estimated cost to close all five items is $6,500. Where the contract permits a holdback set at 150 percent of the estimated remaining work, the owner withholds $6,500 times 1.5, or $9,750, until each item is cured. As items are signed off, the withheld amount is released item by item until the list reaches zero and the balance is paid.
Variations and Edge Cases
A punch list varies by contract form, project size, and jurisdiction. On larger projects the list is split by trade or by building area, with separate walkthroughs per phase. Terminology and mechanics also shift across systems, and some items fall outside the list entirely.
Variation | How it behaves |
|---|---|
Snag list | The same concept in the United Kingdom and much of the Commonwealth |
Zero punch list | Owner requires no open items before signing, common on high-spec builds |
Latent defects | Hidden problems found after closeout, handled under warranty, not the punch list |
Multi-phase closeout | Separate punch lists per designated portion under G704 |
Punch List vs Substantial Completion
A punch list is often confused with substantial completion. A punch list is the itemized set of incomplete or defective items that remain; substantial completion is the milestone that triggers the list. One is a document, the other is a legal and contractual event that starts warranties and retainage release.
Put simply, substantial completion is the moment the owner can use the space, and the punch list is what still needs finishing after that moment. The certificate is signed once, the list is worked down over the days that follow until final completion.
Frequently Asked Questions
Who creates the punch list? The contractor typically prepares the punch list, and the architect verifies and amends it. Under AIA Document G704-2017, the list of items to be completed or corrected is attached to the Certificate of Substantial Completion and accepted by both the owner and contractor.
When is a punch list created? A punch list is created at substantial completion, the point where the owner can occupy or use the space for its intended purpose even though minor work remains. It is recorded during a walkthrough and finalized before final payment.
How does a punch list affect retainage? Owners commonly release most retainage at substantial completion but hold back an amount against the open punch list. Law firm Cox Castle notes this holdback often runs 150 to 200 percent of the estimated cost of the remaining work until each item is cured.
What is the difference between a punch list and a snag list? They are the same thing. Punch list is the United States term; snag list is used in the United Kingdom and much of the Commonwealth for the list of incomplete or defective items to correct before completion.
