What is the correct term for the standard date that should be used when applying the in-effect code for a new occupancy?

The standard date that should be referenced when applying the in-effect code for a new occupancy is the date of plan approval. This date signifies when the plans and specifications for the occupancy were officially reviewed and accepted by the relevant authority having jurisdiction.

Using the date of plan approval ensures that the building is subject to the code requirements that were in place at that time, which is crucial for ensuring compliance with safety standards and regulations. This helps maintain consistency in how codes are applied, protecting both the property and its occupants by adhering to the standards that were relevant upon approval of the plans.

The other options refer to different stages in the construction process or inspection timelines, which do not reflect the specific point at which the applicable codes are determined. For instance, the initial approval date may not correspond to when the plans were finalized, and the construction start date typically occurs after the plan approval, making it unsuitable for referencing applicable codes. Similarly, the inspection date is concerned with compliance checks during construction rather than the standards applicable at the planning phase.
