House committee substitute to the 1st edition makes the following changes. 

Revises the proposed changes to GS 58-79-1 (covering fires investigated, reports, and records) to authorize the Commissioner of Insurance (Commissioner) through the Office of State Fire Marshal and the Director of the State Bureau of Investigation (SBI) through the SBI (was, the Commissioner and the SBI), in addition to local law enforcement and fire officials/agencies, to investigate all fires where property has been destroyed or damaged and to determine whether the fire was set intentionally or by carelessness. Now grants the SBI Director and the Commissioner the right to supervise and direct a preliminary fire investigation upon determination by the official who conducts the preliminary investigation (was, when the Director or the Commissioner deems it expedient or necessary). Replaces the new provision giving the SBI Director exclusive right to supervise and direct investigations in cases involving death or serious bodily injury, to instead provides that if the official who conducts the preliminary investigation requests investigative assistance from a State agency, the SBI Director, through the SBI, has the exclusive right to supervise and direct investigations in cases involving death or serious bodily injury, first- or second-degree arson, buildings owned or occupied by State or local government, and buildings owned or leased by education institutions, churches, or religious buildings. 

Makes technical changes to the proposed changes to GS 58-79-5, GS 58-79-10, and GS 58-79-15
