A fire sprinkler systems design can be defined as an essential element that protects the residents from sudden fire attacks. It is the fundamental requirement that is accountable to the safety and security of human beings as well as their valuable assets from unexpected fire events. In California, the installation of fire sprinkler system design is obligatory for both commercial and residential buildings including offices, agencies, warehouses, apartments, retail stores, pantries, and many more. It is a legal requirement to install fire sprinklers in those buildings that are used for commercial purposes. In this article, we will break down the requirement of fire sprinkler system design for commercial as well as residential buildings and the maintenance of these sprinkler systems in California


Fire Sprinkler System Design is one of the best methods in the protection against unexpected fire outbreaks. These sprinkler systems have contributed a significant part to offer protection to the lives of the occupants as well as their belongings. Fire events may cause by a sudden rise in temperature that leads to the excessive loss of the lives of inhabitants and their assets. In the fire sprinkler system design, the main component is a fire sprinkler, which is responsible to discharge a sufficient amount of water immediately after the detection of an unexpected temperature rise. If these sprinkler systems are not installed in such structures, it may cause excessive loss to the lives of many individuals including laborers, staff members, managers, peons, and so on. In California, the government made it compulsory to install the fire sprinkler system design by following fixed rules and principles to avoid any future loss. 

Requirement of Fire Sprinkler System Design

In California, fire sprinkler systems are mandatory to be installed in all types of buildings including fire zones, fire hydrants, water supply control valves, multi-floor homes, and self-storage units. The requirements of fire Sprinkler system design in these parts are mentioned below:

  • Fire Zones 

In California, it is obligatory to install the fire sprinkler systems in every newly constructed building or land, especially if its fire zone exceeds the boundary of 5000 square feet. Any sort of restoration or repair which exceeds the range of 5000 square feet is also required to have the fire sprinkler system. 

  • Fire Hydrants  

Fire Sprinkler system is one of the most preferred approaches and is more probable to be installed in a separate building because fire hydrants raise the pressure in fire sprinkler systems. Therefore, a special region or a separate building is essential to install these systems with an external door or a side entrance. 

  • Water supply Control Valves 

Water supply control valves located in staircases are necessary to be well-secured and easily accessible for the quick process during a fire attack. These water-flow valves should be set with data representing the regions or parts covered. 

  • Multi-floor Homes

Fire sprinkler system is required to be installed in every multi-floor home that contains more than two housing units. The older structures are also required to install these fire sprinklers by taking authorization for the development. Fire sprinkler system is also applicable to lofty buildings, which are more than 55 feet tall.

  • Self-storage Units

Automatic fire sprinklers are necessary to install in all the self-storage units, excluding the condition when they serve the purpose of single-story with no inner walkways and with a 1-hour fire barrier. 

Maintenance of Fire Sprinkler System Design

Fire Sprinkler System Design will require less maintenance under ordinary conditions, with an exemption of the following important points:

1. It is required to observe the fire sprinkler system’s water pressure daily, on the riser gauge instrument. If the device gives zero reading, communicate with a qualified fire sprinkler servicer for a checkup.

2. Open the system’s test valve yearly until the bell starts to ring. It is normal if there is a delay of around 30 to 60 seconds. If the alarm or bell fails to ring after the delay period, you need to contact a certified fire sprinkler worker for an examination.

3. Keep the fire sprinkler system safe from dust and any other type of garbage or impurity that may obstruct operation.

4. Don’t paint the Fire sprinkler systems because the paint can block the sprinkler system and cause obstacles in performing the proper operation.


By summing up this article, it is cleared that Fire sprinkler system design is one of the major requirements for both commercial and residential buildings in California. It can save millions of occupant’s lives and their properties. They offer the protection of human beings against sudden fire attacks. In California, the government has enforced the law and made it mandatory to install fire sprinkler systems in all types of building structures.
