Use Classification "Item 15 (Offices)" in the Order for Enforcement of the Fire Service Act

"Item 15" in Appended Table 1 of the Order for Enforcement of the Fire Service Act is classified as "Offices, banks, and other similar facilities (workplaces not falling under any of the preceding items)."

Unlike "specified fire prevention properties (facilities accessed by a large number of unspecified people)" such as restaurants (Item 3), hotels (Item 5), and stores (Item 4), it is classified as a "non-specified fire prevention property" primarily staffed by specific employees, so the installation standards for fire equipment are set relatively leniently.

Main Examples of Facilities Included in Item 15

Main Installation Standards for Fire Protection Equipment for Standalone Properties (Item 15)

The obligation to install major fire protection equipment arises depending on the building's "total area" and "number of stories."

Equipment Name Installation Mandatory Line for Item 15 (Offices)
Fire Extinguisher Total area of 300㎡ or more (Basements, windowless floors, and 3rd floors and above: floor area of 50㎡ or more)
Automatic Fire Alarm System Total area of 1,000㎡ or more (Basements, windowless floors, and 3rd floors and above: floor area of 300㎡ or more)
Indoor Fire Hydrant System Total area of 700㎡ to 3,000㎡ or more (Varies depending on structure, fire resistance performance, and interior restrictions)
Sprinkler System In principle, floors on the 11th story or above, or total floor area of basements is 2,000㎡ or more
Guide Lights (Evacuation Exits / Aisles) Basements, windowless floors, and floors on the 11th story or above above ground (General above-ground floors can use guide signs, etc.)
Emergency Alarm Equipment/Systems Capacity of 50 persons or more

Main Practical Points Regarding Item 15

  1. 1. Transitioning to "Item 16-A (Mixed-Use)" Due to Tenant Restaurants or Stores:
    In a tenant building that only contains Item 15 (offices), if even a single restaurant (Item 3) or retail store (Item 4) moves in, the entire building will be changed to a "mixed-use specified fire prevention property (Item 16-A)." This frequently leads to troubles involving extra costs for adding fire protection equipment, such as the entire building suddenly requiring an automatic fire alarm system which was previously unnecessary.
  2. 2. Precautions When Changing Layouts (Partition Construction):
    When new private rooms (such as conference rooms or executive offices) are created during office renovations or expansions, it generally creates unguarded areas for fire detectors and sprinklers on the ceiling, necessitating construction to add or relocate detectors.
