Which Illinois statute establishes the Standard Fire Insurance Policy provisions that all IL homeowners policies must meet or exceed?

Why this is the answer

Illinois codifies the Standard Fire Insurance Policy at 215 ILCS 5/397. Any homeowners or fire policy delivered in Illinois must contain provisions at least as favorable to the insured as the statutory Standard Fire Policy. The ISO HO-3 and HO-5 forms satisfy this requirement by incorporating equivalent or broader language. The other citations cover compulsory auto FR, condominium property, and unfair claims practices respectively, not the Standard Fire Policy.
