Why do plan check comments happen?

Most comments come from code-compliance gaps (egress, accessibility, fire rating, occupancy), missing or unclear details, and inconsistencies introduced during design revisions and copy-paste — for example a spec that contradicts the drawings, or a detail referenced but not included.

How do you reduce plan check comments?

Run a thorough cross-discipline review of the full set (drawings, specs, and applicable codes) before submitting. Catching code gaps, spec-vs-drawing conflicts, and coordination issues up front means fewer reviewer comments, fewer resubmittals, and a faster permit.

What is the difference between a comment and a correction?

They are used interchangeably by most jurisdictions. Both refer to an item the reviewer requires you to fix and resubmit before approval. Some departments call the marked-up set 'redlines.'

A plan check comment (also called a correction or redline) is an issue a building department's plan reviewer flags on your submitted construction drawings. Each comment must be resolved and resubmitted before the permit is issued. Comments typically cite a code section, missing information, or an inconsistency between sheets or disciplines. More comments mean more resubmittals — and a slower permit.

Why comments happen

Code-compliance gaps: egress, accessibility (ADA), fire rating, occupancy
Missing or unclear details referenced from the plans
Spec-vs-drawing contradictions (the spec says one thing, the drawings another)
Cross-discipline coordination conflicts (MEP vs. structure, fixtures vs. architecture)
Copy-paste and revision errors carried across sheets

How to reduce plan check comments

The fastest way to fewer comments is a thorough pre-submission review of the entire set — drawings, specs, and applicable codes — so issues are resolved on paper before the reviewer ever sees them. That is exactly what AI plan checking does: it flags code gaps, spec-vs-drawing conflicts, and coordination issues with evidence for each, so your team fixes them first. See how to reduce plan check comments for a deeper playbook.
