Existing buildings · Defined
Change of occupancy
A change in a building’s use or occupancy classification that may trigger additional requirements under the applicable code.
Why it matters
The local authority determines the applicable classification and approvals. A proposed use should not be assumed permissible simply because the physical space appears suitable.
In practice
A project example
A former warehouse is proposed for assembly use, prompting review of egress, fire protection, and occupancy approvals.
