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.
