A certificate of occupancy (CO) is issued after inspections confirm the building meets life safety, fire protection, and structural integrity standards (Option A).

Why Option A is Correct?

Life safety systems include fire alarms, sprinklers, emergency exits, and structural safety components, which are mandatory for occupancy.

Building codes require that these systems meet regulatory compliance before occupancy is allowed.

IFMA's Operations & Maintenance competency states that facility managers must ensure safety and regulatory compliance before allowing occupants into a new space.

Why Other Options Are Incorrect?

Option B (Potable water systems): While potable water is important, it is not a primary factor for a certificate of occupancy.

Option C (IT/Network systems): IT systems are not a legal requirement for occupancy certification.

IFMA Core Competency: Operations & Maintenance -- Ensures compliance with building occupancy laws.
