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

Chapter 150's code-applications section, § 150.09(A), sets the electrical-installation rules new buildings in unincorporated Macon County must meet, and item (7) sends smoke-detector wiring to a specific outside standard: § 907.2.10 of the 2012 edition of the International Fire Code. That cross-reference sits right after the county's emergency-lighting rule in item (6), which requires battery-backup fixtures, in adequate number and location, to light staircases and egress paths in every new building, including ones with a generator or a separate alternate power supply, so the two requirements are meant to work together. Because smoke-detector circuits are electrical work, installing or altering them falls under the same permit and inspection rules as the rest of the building's wiring: a permit is required before the work starts, wiring must be inspected before it is concealed, and a final approved inspection is a condition of the certificate of occupancy.

The county backs this with a real penalty. Anyone, whether an individual, firm, or corporation, who violates any provision of Chapter 150, including the smoke-detector requirement folded into § 150.09, can be fined up to $500 for each offense on conviction, and the code treats every day a violation continues as a separate offense, which can multiply exposure quickly on a project that drags on without correcting the defect. The Control Authority, defined as the Planning and Zoning Department or the designated building or electrical inspector, is the office that enforces the requirement and can refer unresolved cases to the County Electrical Commission.
