The provisions of the Building Code are not intended to prevent the use of any material, alternate design or method of construction not specifically prescribed by the Building Code, provided any alternate has been demonstrated to meet the purpose of the code.
The building inspector may approve any such alternate, provided the inspector finds that the proposed design is satisfactory and complies with the provisions of the code and that method or work offered is at least the equivalent of that prescribed in the code in suitability, strength, effectiveness, fire resistance, durability, safety and sanitation. The customer is responsible to provide proper documentation and evidence of suitability for each alternate proposed.
