The provisions in this Code are intended to establish minimum acceptable standards for public health and public safety, fire protection, structural sufficiency, conservation, environmental integrity, barrier-free use and access. It is intended that all installed features of a building, whether required or not, would be designed in conformance with good engineering practice and would meet the applicable requirements of the Code. Good design is necessary to ensure that the level of public safety established by the Building Code requirements would not be reduced by a voluntary installation. Voluntary installations should not detrimentally affect other applicable provisions required by the Code.
There is a public expectation that installed features in a building would meet their intended function and conform to the Building Code.
