These codes rely on the accurate determination of high-hazard, or Group H, occupancy designation to ensure proper building features are provided for occupant and facility safety. Theyre not supporting the floor or roof system, and theyre not handling any lateral load (that is, theyre not shear walls, or braced wall lines as defined in the IRC). They are used to ensure that a fire in one part of a building does not spread to other parts of the building, helping to keep occupants safe. Typical occupancy classifications in the manufacturing and industrial sectors include: The IBC further categorizes High Hazard (Group H) occupancies into one of five subgroups. The IBC and IFC utilize occupancy classification to provide rationale criteria to match a buildings use and occupancy with the features required to address fire hazard and life safety considerations.

Many urban buildings are mixed occupancy buildings and use one of these described approaches. March 2021 The fire-resistance rating for the fire barriers and horizontal assemblies depend on the height of the control area in stories above grade, per IBC Table 414.2.2. This tool allows designers to quickly view ratio calculations for separated occupancies based on the allowable floor and buildingareas. The distance between the buildings face and the closest interior lot line, to the centerline of a street, alley, or public way, or to an assumed imaginary line between two buildings on the same lot is referred to as the fire separation distance. Mixed-use buildings or sites are structures or sites that are part of a mixed-use development that includes two or more different land uses permitted within the underlying zoning district. Think of the occupancy certificate for a building as a contract between facility management and the building and fire official the facility is agreeing to manage hazardous materials according to the agreed-upon limitations for storage and use throughout the life of the operation. The International Building Code (IBC) classifies all of these buildings as Residential Group R; hotels are Group R-1 occupants are mostly transient, and apartment buildings and dormitories are Group R-2 occupants are mostly permanent/non-transient.
