CONTEXT WHAT IS THE BUILDING CODE?

• It is a Building Owner’s responsibility for the life

safety of the occupants of a building.

• Architects advise building owner’s of Building Code

Requirements which are:

“minimum requirements of the applicable

codes and standards.”

The Building Code:

CONTEXT ARCHITECT’S ACT

Regulation 27 of the Architects Act

• Requires that Architects must when submitting an

application of a building permit, include with the

information that is submitted Building Code
