Summary
Skokie's amended building code requires smoke detectors under the state Smoke Detector Act in Group R-1 occupancies and adds a local rule: every multi-unit or mixed-use structure must have a smoke detector at the top of each interior stairwell and on every floor landing of a shared stairway.
907.2.10.1.1 Group R-1. Delete the text and replace with the following: Single- or multiple location smoke detectors shall be installed in accordance with The Smoke Detector Act, 425 ILCS 60/1 et seq., and rules and regulations related thereto, are hereby adopted by reference in Group R-1, except as modified as follows: ... Add [F] 907.2.10.1.2.4 Every structure which (1) contains more than 1 dwelling unit, or (2) contains at least 1 dwelling unit and is a mixed-use structure, shall contain at least 1 approved smoke detector at the uppermost ceiling of each interior stairwell. If each unit opens directly into a common enclosed stairway, a detector shall also be installed on the ceiling of each floor landing.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 205 | Zoning: Supplement 89).
Full Breakdown
Skokie adopted the 2021 International Building Code at Section 22-31 and then amended its smoke-detection provisions at Section 22-33. , and its implementing rules, adopted by reference, subject to the Village's own modifications. 4: any structure that contains more than one dwelling unit, or that contains at least one dwelling unit and is a mixed-use building, must have at least one approved smoke detector installed at the uppermost ceiling of every interior stairwell. Where an individual unit opens directly into a shared, enclosed stairway, the Village also requires a detector on the ceiling of each floor landing along that stairway, so residents get warning both inside the stairwell shaft and at every point units connect to it.
These stairwell and landing detectors are layered on top of, not a substitute for, the detectors the Illinois Smoke Detector Act and the balance of the adopted IBC and IRC already require inside dwelling units and outside sleeping areas. Because the requirement is tied to occupancy type and building configuration rather than square footage, it reaches everything from a small two-flat with a shared entry stairway to a larger mixed-use building with ground-floor retail and residential units above.
Violations & Fines
Failing to install or maintain the required stairwell and landing smoke detectors is enforced as a Chapter 22 building code violation under the general penalty in Section 1-6, and a certificate of compliance under Section 111.3 will not issue until inspectors confirm the detectors required by Sections 907.2.10.1.1 and 907.2.10.1.2.4 are in place and functioning.
