The principal accountable person for an occupied higher-risk building must as soon as reasonably practicable after the relevant time prepare a report (a "safety case report") containing—
any assessment of the building safety risks made under section 83 by an accountable person for the building, and
a brief description of any steps taken under section 84 by an accountable person for the building.
The principal accountable person must revise a safety case report if they consider it necessary or appropriate to do so following—
any further assessment under section 83 made by an accountable person for the building, or
the taking of further steps under section 84 by an accountable person for the building.
The Secretary of State may by regulations make further provision about the content and form of safety case reports.
In this section "the relevant time" means—
the time when the building becomes occupied, or
if later, the time when the person becomes the principal accountable person for the building.
