What a good response to correction list has
General guidance, not the City of Industry’s own rules. Check its page before you resubmit.
- Answer every comment, in the reviewer’s order and numbering, so nothing is missed.
- Say plainly what you changed for each comment, or why no change is needed.
- Name the sheet and detail where each change is, so the reviewer can find it fast.
- Mark changes on the drawings (clouds or deltas are common) and keep sheet numbers the same.
- Send the response letter, the revised drawings and any new calculations together.
