There are numerous variables that come into play when determining if a building needs fire sprinklers or a fire alarm, or other fire protection systems. Some of these variables are size of building, occupancy group, occupancy use, type of construction, available fire flow and emergency vehicle access to the building. Your design professional will complete a Code Analysis based on requirements from the International Fire Code and International Building Code. This Code Analysis, typically completed during the Planning and Building permit processes, provides the information necessary to determine what fire-protection systems, if any, are required by the IFC.
