For purposes of this paragraph, arson of property does
not include one burning or causing to be burned his or
her own personal property unless there is an intent to
defraud or there is injury to another person or another
person’s structure, forest land, or property.
Just as you'd expect. Whether the property in question are books you own, or a shed, or your entire house it's your property and it's not a crime to turn your property into a bonfire so long as doing so doesn't break other criminal laws.
