Peoria County, IL Fire Regulations: Smoke Detectors (2026)

Section 6-89 of the Peoria County Code, in the bed and breakfast establishment article, requires every licensed bed and breakfast to meet the state fire marshal's requirements for one- and two-family dwellings and then layers on eight additional standards specific to guest lodging. Item (8) is explicit: smoke detectors shall be provided in each guest room, not merely somewhere in the building or on each floor. The surrounding paragraph requires manual fire extinguishers on each floor that meet NFPA 10, the national standard for portable fire extinguisher installation; storage of combustibles or flammable liquids only in approved metal containers, with none stored in or under stairways; metal trash containers throughout; a ban on cooking facilities inside guest rooms; adequately lighted hallways and stairways; a ban on portable heating devices in guest rooms; and a requirement that the operator submit a floor plan of the establishment to the fire department that provides its fire protection.

This provision is scoped to bed and breakfast establishments in the unincorporated county under Chapter 6, Article III; it does not create a stand-alone smoke-detector mandate for ordinary single-family homes, which instead fall under whatever building or residential code the county or the applicable fire protection district has separately adopted. The health authority that licenses bed and breakfasts inspects each establishment at least twice a year under § 6-101, and those inspections can surface fire-safety deficiencies under § 6-89 alongside the sanitation standards in § 6-84 through § 6-90.
