What a good response to plan check corrections has
General guidance, not the City of Belmont’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.

In general, answer every comment in a response letter that says what changed and on which sheet, then resubmit the revised drawings the way the City of Belmont asks. Check its own instructions first.
What should a resubmittal to Belmont include?

Where do I send my resubmittal to Belmont?
