Arson Information

Arson fires account for a large percentage of all fires. Because arson fires can be somewhat difficult to determine or detect, the actual number of arson fires tend to be underreported. Some fire officials estimate that as many as 50 percent of all fires may be intentionally set. In the United States, more than 700 lives are lost each year in arson-related fires. Although, fire officials often try to measure the cost of arson using statistics, such as lives lost or dollars lost, the actual cost involves several factors that are more difficult to measure (change in neighborhood, environment, etc.). Arson fires in a neighborhood can have a significant impact on property values of all structures in the area.

What Can You Do About Arson in Your Community?

If we are to effectively address the arson problem in our communities, every citizen must participate in combating this vicious crime. This means understanding the impact arson has on the community and cooperating to prevent arson, and reporting suspicious persons and activities that may result in arson.

Consult with your local fire or police officials to determine the extent to which arson is a problem in your community or neighborhood. If a particular part of your community is plagued by arson, you should get involved before the problem spreads or becomes worse. Generate interest among your neighbors and friends. Start or participate in a community watch program. Report all suspicious activity to the local police department or fire department. Everyone needs to be involved in Arson Prevention.

Do You Have Information About A Possible Arson?

A statewide Arson Hotline, (800) 252-2947, has been established so that citizens may anonymously provide information about a suspicious fire that has occurred or may occur. You may be eligible for an award up to $2,500 for providing information leading to the arrest and/or conviction of an arsonist.

What are Common Motives for Arsonists


  • Thrill seeking
  • Recognition as a hero (such as firefighter-arsonists)
  • Sexual gratification


  • Malicious or mischievous fire-setting that results in damage to property
  • Most often set by juveniles
  • Frequent targets are schools, abandoned or vacant structures, and dry vegetation

Crime Concealment

  • Fire is set for purpose of covering up crimes such as murder, burglary, destruction of records and auto theft
  • Goal is to eliminate evidence left at scene


  • Fires set in retaliation for some real or perceived injustice
  • Perceived wrongdoing may have occurred months or years previous to the fire-setting activity
  • Is the most common motive for a serial arsonist


  • Fires set to further their own or group's social, religious or political causes
  • May involve government buildings or property, houses of worship, clinics or laboratories
  • Perpetrators or groups involved often claim responsibility for political or media attention


  • Fires set for direct monetary gain or for indirect gain to eliminate debt or to eliminate business competition

What is the Real Cost of Arson?

Human Cost: All arson fires are crimes against people, even if the intended target is a vacant building, trash or woods. These fires must be controlled and extinguished by firefighters; and therefore, human life is endangered whenever a fire is set. Certainly, a major blaze in an occupied apartment building is much more severe than a small fire set in a field. However, every year firefighters are killed or injured in responding to or combating small, open air fires.

Direct Costs: The value of the property destroyed by the fire; the cost of firefighting supplies and staff to control and extinguish the fire; the cost of insurance coverage on the property.

Indirect Costs: The loss of tax revenue, since the property may be taken off the tax rolls; the welfare or unemployment costs of the workers put out of work, even if the building is rebuilt; the medical expenses of civilians and firefighters injured by the fire; the disability retirement costs of injured civilians and firefighters; increased insurance costs.

Preventing Arson

Most arson fires are started outdoors. Don't make it easy for an arsonist to start a fire or easy for an outdoor fire to spread to a building.  Steps that can be taken to reduce the incidents of arson:

  • Keep leaves, firewood, overgrown brush and shrubbery and other combustibles away from buildings.
  • Keep doors and windows locked when a building is unoccupied. Board up abandoned buildings. Do not use double cylinder deadbolt locks without keeping a key nearby, bars without quick release mechanisms, or other security provisions that could trap a person in a building with a deadly fire.
  • Store all flammable liquids such as; paints, gasoline, and mowers in an approved storage location: locked cabinets, locked storage units, and locked garages (prevent access to kids). Also, keep away from heat sources such as furnaces and any type of heaters.
  • Report suspicious activity near houses or other buildings to the local police and support Neighborhood Watch programs.
  • If you suspect a child is setting fires, notify the proper authorities. It may not be "just a phase" they are going through. Keep matches and lighters out of reach and out of sight of young children. 
  • If you know or suspect that an arson crime has been committed, contact your local fire or police department.
