If a person commits the crime Arson they can face from 1 to 20 years in prison.
If the person just committed the Arson as a first offense and no one was in the building then they might get up to 5 years max in prison but if someone set fire to a building with someone in it hoping to burn them up then it's considered aggravated Arson Plus attempted murder which can carry a prison term from 15 to 20 and sometimes even 25 years.
Now if the person dies or people die in the fire then the person that set the fire can be charged with Aggravated Arson and Murder as well.
And when you get a Murder Charge you're likely to spend a minimum of 25 years in prison before you could be eligible for parole or you may be sentenced to life without Parole if someone or some people died in the fire you set.
