When a significant deviation from the approved plans is discovered during an inspection, the appropriate action is to require a submittal of a set of corrected plans. This is necessary to ensure the system is reviewed and approved in compliance with the applicable codes and standards.
Issue a violation notice (A): While this may be a secondary step if the system does not meet code, it is not the first step when encountering unapproved changes.
Evaluate the installation for compliance (B): Inspectors cannot simply evaluate the installation without updated plans, as the plans serve as the approved baseline for design compliance.
Require corrected plans (C): This step ensures that the new design is documented, reviewed, and approved before proceeding. It maintains compliance with NFPA standards.
Indicate modifications on the approved plan (D): Altering plans without proper review is not acceptable and does not ensure the system meets the original intent.

NFPA 1 and NFPA 13: Systems must comply with approved designs and significant changes require resubmittal for review.
