Knox Box Key Access

Permit Sonoma Fire Prevention

Chapter 5. Section 506 of the California Fire Code, Sonoma County requires all new construction and existing buildings to be equipped with a fire department access box to provide for rapid entry and prevention of damage to buildings and gates. 

In an effort to provide both fire department emergency access and building security for buildings, the Fire Prevention Division has selected the Knox Box public Safety Key Box System for use in accomplishment of these goals. This is a system that will allow us access to a key for non-destructive entry into a building. 

This is a mandatory system for commercial establishments within the county as well as all electric commercial and residential gates within the county. In this program the building owner/occupant orders the correct device to install on the building to secure a key(s) for use by the fire department in an emergency, Personnel should encourage the use of this box at any opportunity. 

The Knox Box rapid entry system is a secure emergency access program developed for property owners and fire departments. When a fire breaks out or there is a medical emergency, Knox products allow immediate entry into buildings and property without forced entry damage or delay. Property owners store entrance keys, access cards and floor plans in high-security Knox-Boxes mounted near building entrances. Each Knox Box purchased by a property owner is keyed to a single master key controlled by the fire department. 

In addition to key boxes and vaults, Knox padlocks and key switches operate with the same master key. There are so many gated communities today that fire and police departments are delayed when responding to emergency calls. Increased property damage and even total loss is a threat when property is not accessible. 

Please contact the Permit Sonoma Fire Prevention Division at (707) 565-2361 for questions regarding the Knox Box System.
