What Is a Plan Check Comment?

Last reviewed: September 2026

A plan check comment is one numbered correction from the building department's review of a permit set. The design team answers it in writing, revises the sheets if the comment requires a change, and the plans examiner clears it on backcheck.

Issued by
The plans examiner, on the jurisdiction's form or portal
Addressed to
The applicant, usually through the architect of record
Typical contents
A number, a code citation, and the change or document required
Closed by
A written response plus any revised sheet, accepted on backcheck
If ignored
The permit, or the next inspection, stays open
Lives in
The comment letter, the response log, and the revised set

Definition

Plan check comment

Comments arrive as a letter, a spreadsheet, or marks on a PDF. Each one cites a code section, a local amendment, or a missing document. A comment is not a suggestion from a coordination meeting. It is an item the authority having jurisdiction expects to close before the permit, or before the next inspection that depends on it. The response has to meet the comment that was written, not a paraphrase of it.

In depth

What a usable comment contains

A comment that can be answered names the sheet, the code section, and the problem. 'Egress width' with no stair and no section is hard to close. Teams should ask the examiner to clarify a comment that cannot be located, and they should do it in the response log so the request is on the record.

Some comments are completeness items: calculations not sealed, a form not uploaded, a sheet missing from the index. Those close by providing the document. Others require a design change. Those close only when the clouded revision matches the response.

How to write the response

Repeat the comment number. State the action in one line: revised detail 5/A-501, clarified by note 3, or exception requested under the cited section. Point at the sheet and the delta. Attach the revised PDF the portal asked for, with the same revision number in the title block.

Do not answer a code comment with a product cut. The examiner is checking the documents that will be permitted. A shop drawing that does not exist yet cannot clear a comment on the permit set unless the city has agreed to a deferred submittal.

Backcheck is a second review, not a new design

On backcheck the examiner reads the response against the open items. A clean item gets marked resolved. An item whose revision created a new conflict, such as a wider door that now swings into a rated corridor, can generate a new number.

Owners who track only the first letter underestimate the work. The log that matters is the one that shows every number, the date of the response, and the date it was cleared. That log is also what a lender asks for when the permit is on the critical path.

Who owns which comment

Architectural, structural, mechanical, electrical, plumbing, and energy comments land on different consultants. The architect of record usually assembles one response. A structural comment answered by the architect, without the engineer, is a stamp problem as well as a code problem.

Split the letter by discipline on day one. Waiting until the cycle deadline to discover that the energy modeler never saw comment 22 is how resubmittals go out incomplete.

Comments that survive into construction

Approved conditions and leftover deferred items show up in the field as inspection holds. The superintendent needs the cleared set, not the first issue. A comment that was 'resolved by note' still has to be on the sheet the installer is holding.

If construction starts on a partial permit, write down which comments remain and which inspections they block. A foundation-only release does not clear the egress comments that govern the upper floors.

Examples

Plan check comment on a real project

  • 01

    Comment 14 cites IBC stair width and names sheet A-201. The architect revises the run, clouds it, and the response line quotes the new dimension.

  • 02

    Comment 3 says the structural calculations are missing a seal. The engineer reseals and uploads the PDF. No sheet change is required.

  • 03

    A backcheck rejects comment 9 because the added door conflicts with the fire-rated corridor shown on A-401.

FAQ

Frequently asked questions

It is one numbered item from the building department telling the applicant what must change, or what document must be provided, before the permit review can move on. The design team answers it in writing and the examiner clears it on backcheck.

Use the city's numbering. For each item, state the action, the sheet or document that changed, and the revision. Cloud the change on the drawing. Upload the file type the portal requires.

Yes, when the cited section does not apply or an approved alternate meets it. The challenge belongs in the response, with the section and the reason. The examiner accepts or rejects it. A phone call that is not written down does not close the item.

Backcheck is the examiner's review of the corrected submittal. It confirms that each open comment was answered. It can add a comment if the revision created a new code issue.
