Iowa Code Title IX. Local Government [Chs. 331-420] § 364.16. Municipal fire protection

Each city shall provide for the protection of life and property against fire and may establish, house, equip, staff, uniform, and maintain a fire department. A city may establish fire limits and may, consistent with code standards promulgated by nationally recognized fire prevention agencies, regulate the storage, handling, use, and transportation of all flammables, combustibles, and explosives within the corporate limits and inspect for and abate fire hazards. A city may provide conditions upon which the fire department will answer calls outside the corporate limits or the territorial jurisdiction and boundary limits of this state. A city has the same governmental immunity outside its corporate limits when providing fire protection as when operating within the corporate limits. Fire fighters operating equipment on calls outside the corporate limits are entitled to the benefits of chapter 410 or 411 when otherwise qualified.
