A punch list is the list of work items to be completed or corrected before a construction project reaches final completion. Under the AIA general conditions, the contractor prepares it when the work is nearly finished, and the architect inspects and supplements it as part of determining substantial completion. Completing the punch list is the gate between substantial and final completion.

## Where the punch list sits in closeout

The punch list belongs to the substantial completion process (AIA A201-2017 §9.8). The sequence on a typical project:

1. The contractor judges the work substantially complete and prepares a comprehensive list of items remaining to be completed or corrected.
2. The architect inspects. If the work qualifies, the architect issues the certificate of substantial completion and attaches the punch list, adding items the contractor missed.
3. The contractor completes or corrects the listed items.
4. The architect reinspects, and final completion and final payment follow.

Substantial completion matters commercially because it typically starts warranties, shifts insurance and utility responsibility to the owner, ends liquidated damages exposure, and releases most retainage. The punch list is the documented residue: what remains, agreed and bounded, after that milestone.

## What belongs on a punch list

Punch items are completions and corrections within the existing contract scope: the door that does not latch, the paint touch-up, the missing escutcheon, the mislabeled panel schedule. Two categories commonly get confused with punch work and should be kept off the list:

- **Changes.** New scope discovered at walkthrough is a [change order](/glossary/change-order) discussion, however small.
- **Warranty items.** Defects emerging after acceptance are warranty claims, handled under the warranty provisions rather than held against final payment.

For design teams, punch list discipline is mostly writing discipline: items described specifically enough ("relocate thermostat in room 214 per A-601", "adjust closer, door 3105") that a reinspection has a yes-or-no answer.

## Related terms

- [Construction administration](/glossary/construction-administration): the service phase the punch process concludes.
- [Change order](/glossary/change-order): the instrument for new-scope items found at walkthrough.
- [Submittal](/glossary/submittal): closeout submittals (warranties, O&M manuals) run alongside the punch list toward final completion.

## Frequently asked questions

**Who writes the punch list?**
Under the AIA documents, the contractor prepares the initial comprehensive list; the architect inspects, verifies, and adds anything missed. In practice many owners and architects also walk the project and contribute items.

**Why is it called a punch list?**
The traditional explanation is that completed items were once punched through the paper list. The term is standard US usage; UK practice calls the same list snagging.

**What is the difference between a punch list and a warranty claim?**
Punch items are known incomplete or incorrect work documented at substantial completion and finished before final payment. Warranty claims cover defects that emerge after acceptance and run under the warranty clauses, typically for a year or more.

**Does the owner hold money against the punch list?**
Commonly, yes. Retainage or a specific withholding tied to the value of incomplete punch items is held until the architect confirms completion, per the contract's payment provisions.

**When is a project substantially complete?**
When the work is sufficiently complete that the owner can occupy or use it for its intended purpose, as determined by the architect. The punch list documents what remains at that point.
