Building codes must be followed in any construction project. Architects and contractors are required to adhere to the codes when building any structure so as to protect the safety of the occupants and the structural integrity of the building. Codes anticipate emergency situations by requiring emergency exits and that the disabled have easy access. Standards exist that apply to stairs, railings and surface composition. In many cases, a building code violation can lead to debilitating injuries. It is the duty of the contractor and property owner that all building codes be followed or they may be liable for any resulting injuries.
