What does "Additional Upgrading for Multiple Major Occupancies [Change of Use]" typically involve?

"Additional Upgrading for Multiple Major Occupancies [Change of Use]" typically involves implementing enhanced safety measures across various uses. This process is essential when a building is being modified to accommodate new or different types of occupancies that may have distinct safety requirements. For example, a building initially designed for office use may be converted into a residential or assembly space, which necessitates stricter fire, accessibility, and structural regulations to ensure the safety of all occupants.

Upgrading for multiple major occupancies often requires a detailed assessment of risks associated with the new uses, and it mandates the incorporation of safety features that align with building codes and regulations specific to those uses. Thus, this option correctly reflects the focus on safety and compliance during a change of occupancy.

The other options do not capture the primary focus of this upgrading process. Increasing market value, revising tenant agreements, and conducting historical assessments, while potentially relevant in certain contexts, do not directly pertain to the essential safety measures associated with a change of use in building occupancy.
