1. What is second-degree arson under CRS 18-4-103?

Second-degree arson in Colorado is defined by CRS 18-4-103. This statute makes it a crime to knowingly damage someone else's property with a fire or explosion without their consent. It does not cover buildings or occupied structures that get damaged.

The factors that make an arson accusation second-degree arson are:

  • The property is owned by someone else,
  • The damaged property was not a building or occupied structure, and
  • There was damage to the property.

1.1. What is a “building or occupied structure” in Colorado's arson law?

Colorado's second-degree arson law only covers property that is not a building or occupied structure.

A building is a structure that was designed to house animals, people, or property.1 A building does not actually have to be occupied at the time for there to be arson. Examples of a “building” under CRS 18-4-103 include a:

  • House,
  • Garage, including a detached garage,
  • Boat,
  • Recreation vehicle,
  • Airplane,
  • Trailer of a truck,2 and
  • Mobile home.3

An occupied structure under CRS 18-4-103 is an enclosure or area that can be used by people or animals. To be an “occupied structure” under Colorado's arson laws, the area does have to be occupied at the time of the offense.4

Occupied structures can include:

  • A campground,
  • A tent,
  • An outhouse,
  • An occupied car, or
  • An outdoor dog kennel.5

Setting fire to any of these objects leads to charges of arson in the first degree. Second-degree arson charges under CRS 18-4-103 are for damaging any other type of property.

1.2. Who is the “owner” of a building?

CRS 18-4-103 outlaws committing arson on someone else's property. An owner is anyone with a possessory or a proprietary interest in the property.6

1.3. What constitutes “damage”?

Second-degree arson requires there to be property damage.

Completely destroying the property is not necessary for a second-degree arson accusation.7 However, there has to be more than just scorch marks or discoloration.8 Colorado courts have decided that the property has to change in the fire or ignite in flames.9

2. Legal defenses to a charge of second-degree arson in Colorado

There are numerous legal defenses you can use to defend against a charge of arson in the second degree. The most common are:

  • You did not knowingly start the fire,

You can only be liable for second-degree arson if you knowingly cause a fire or explosion. It is up to the prosecutor to prove this element of the crime. They have to prove it beyond a reasonable doubt.

2.2. The property owner consented

If the owner of the damaged property consented to its destruction, you cannot be liable for second-degree arson. For consent to be a defense, though, all of the property owners have to consent to its destruction.

Example: Ted and Daniel want to burn David's mattress to celebrate a Super Bowl win. David agrees.

2.3. The value of the property was below $100

Challenging the value of the property damage can reduce the severity of the penalties.
