What is a punch list?

Who creates a punch list, and when

The formal punch list comes out of the substantial completion walkthrough. Substantial completion is the point at which the project can be used for its intended purpose even though minor work remains. At that stage the owner, often with the architect or an owner's representative, walks the project with the general contractor. As the group moves through the building, someone records every defect and every piece of unfinished work. That record is the punch list.

The general contractor then takes ownership of the list and assigns each item to the subcontractor responsible for it. On smaller residential jobs the same document is usually produced at the final walkthrough between the builder and the homeowner. Superintendents, project managers, and inspectors also create punch lists of their own throughout a job.

While the contractual punch list belongs to substantial completion, many teams keep a running list during construction. Catching items as they appear keeps the final walkthrough short and the closeout predictable.

An example punch list

Real punch items are short, specific, located, and assigned to a trade. Here is what a typical residential punch list looks like after a final walkthrough:

The punch list process, step by step

1. 1

   Walkthrough

   At substantial completion, the owner, the architect, and the general contractor walk the project together, usually room by room, and record every defect and every piece of unfinished work, ideally with photos.

2. 2

   Assignment

   The general contractor sorts the list by trade and assigns each item to the subcontractor responsible for it, with a deadline for completion.

3. 3

   Completion

   Subcontractors work through their items, correcting defects and finishing incomplete work, then report each item as done.

4. 4

   Verification

   The general contractor, and often the architect or owner, re-inspects each corrected item. Anything that still falls short goes back on the list.

5. 5

   Closeout

   When every item is verified complete, the punch list is closed. Final inspection and handover follow, and the remaining contract balance, including any retainage, is released.

Punch list, snag list, or deficiency list?

The document is the same everywhere; the name changes with the region.

• United States: Punch list

  Also written as punch out list or punchout. Working through the final items is called punching out.

• UK & Ireland: Snag list

  Individual items are snags, and the inspection is a snagging inspection, usually tied to practical completion.

• Australia & New Zealand: Snag list / defects list

  Compiled at practical completion and rechecked at the end of the defects liability period.

• Canada: Deficiency list

  Items are deficiencies, recorded at the substantial performance review.

If your team says snagging, see our snag list app page, which walks through the same workflow in UK and Australian terms.

How software changes the punch process

The traditional punch list is a legal pad or a spreadsheet plus a camera roll full of unlabeled photos. That works, but it means transcribing notes after the walk, matching photos to items by memory, and emailing stale copies of the list around. A punch list app moves the whole loop onto the phone you already carry on the walkthrough: you capture an item and its photos in one step, assign it to a trade on the spot, and track completion status without retyping anything. If you are weighing your options, you can compare the best punch list apps.

Our app, Punch List, is free to download on iPhone and Android. Creating punch lists, documenting items with annotated photos, and tracking completion cost nothing. A Pro subscription ($9.99 per month or $79.99 per year) adds branded PDF reports, digital signatures, and import and export, which matter once you are sending punch reports to owners and subs. The app works offline and your data stays on your device.

Punch list FAQ

Why is it called a punch list?

The most common explanation is that contractors once punched a hole in the paper next to each completed item, one punch by the contractor and a second by the owner or architect verifying the work. Whatever the true origin, the name stuck in the United States, and finishing those final items is still called punching out.

What is a punch out list?

A punch out list (or punchout list) is another name for the same document. Punch out refers to the act of completing the final items on the list before the project is handed over.

Who is responsible for completing punch list items?

The general contractor owns the punch list and assigns each item to the subcontractor responsible for that trade. The architect or owner then verifies the corrected work. On residential jobs, the builder typically handles items directly with the homeowner.

What is the difference between a punch list and a snag list?

Nothing but geography. Punch list is the American term, snag list is common in the UK, Ireland, and Australia, and deficiency list is used in Canada. All of them describe the list of items to complete or correct before final handover.

When is a punch list created?

Formally, at substantial completion, during the walkthrough that precedes final payment. In practice, many teams keep a running punch list throughout construction so fewer surprises show up at the final walk.
