Snag list vs punch list: what is the difference?
They are the same thing. A snag list and a punch list both record defects and incomplete work found before a building is handed over. The difference is geography, not meaning.
- Snag list — the UK, Ireland, Malta, Australia, New Zealand, South Africa and much of the Commonwealth.
- Punch list — the United States and Canada.
You will also meet deficiency list in parts of Canada, and defects list used interchangeably with snag list in formal contract documents.
Where the words come from
"Snagging" comes from the ordinary sense of a snag — a small thing that catches and holds you up. "Punch list" is more literal: the traditional practice was to punch a hole in the margin beside each item on the paper list once it had been completed and verified, so the sheet itself showed progress at a glance.
The practical differences
Although the concept is identical, a few habits differ by region, and they matter if you work across both.
- Formality of sign-off. US practice tends to tie the punch list tightly to substantial completion and to the release of retainage, often with a formal architect certification. UK snagging is frequently more iterative, with lists exchanged repeatedly before practical completion is certified.
- Who compiles it. In the US the architect or owner's representative typically leads. In the UK and Ireland it is common for the contractor to self-snag first, then for the client's surveyor or an independent inspector to produce their own.
- Retention vs retainage. Same idea, different word: a percentage held back until defects are closed out. The snag or punch list is usually what unlocks it.
Which should you use?
Use whichever your client uses. If you are working with an international team, say it once explicitly — "snag list (punch list)" — in the first document, then pick one and stay consistent. The confusion is never really about vocabulary; it is about two people assuming different sign-off processes because they used different words for the same list.
Snagger uses "snag list" throughout, and the reports it produces are equally at home under either name — the content is the plan, the pins, the photos and the status, which is what both traditions actually need.
