Verified Content

Posted by Christopher Combs on July 22, 2025

569.050. Arson in the second degree — penalty.

Setting fire to a building on purpose

Someone commits second-degree arson if they purposely start a fire or cause an explosion that damages a building or a place where people live or stay.

1. A person breaks this law if they knowingly damage any building or livable space by starting a fire or causing an explosion.

2. It’s not a crime if:

  • No one else owns or has legal rights to the property, or everyone who does gave permission; and
  • The fire was started for a legal and proper reason.

3. The person being charged must bring up this defense in court—it won’t automatically apply.

4. This is normally a class D felony. But if someone gets seriously hurt or dies because of the fire or explosion, it becomes a class B felony, which is more serious.
