Enacted in 2005 and modified in 2011, the Knox Box or Key Box Ordinance (Code of Ordances Ch. 11-27 International Fire Code Amendments, IFC Section 506 Key Boxes) was created to assist fire department personnel to gain immediate entry into commercial or industrial buildings in the event of a lifesaving or firefighting incident at a property after normal business hours.
The ordinance specifically requires businesses with fire detection, fire alarm or fire suppression systems that are monitored by an alarm company to have a Knox Box installed.
The ordinance also requires residential property consisting of three or more residential dwelling units to have a Knox Box.
Additionally, fire personnel recommend the Knox Box for other commercial and industrial properties that are not required by code to have the Knox Box.
