Smoke Detector Installation in Logan Square, Chicago

For greystone and multi-unit work, we coordinate with the building owner or property manager to schedule unit access. We walk each unit, document existing detectors and their manufacture dates, map required locations against Chicago code, and plan the hardwired circuit and 3-conductor interconnect cable route. In Logan Square's plaster-wall greystones, the stair hall and the vertical plumbing and electrical chases are our primary cable pathways — we plan routes carefully to minimize wall disturbance and keep cable runs short and code-compliant.

For ADU installations, we treat the coach house or basement unit as an entirely separate scope. We install a new hardwired circuit feeding the ADU's detector locations, run the 3-conductor interconnect cable between all devices within the ADU, and install combo smoke/CO units at every required location. We document the ADU system on its own completion certificate, distinct from the main dwelling, which is what Chicago's ADU permit inspector expects to see.

For owner-occupied units in two-flats and greystones, we often do a combined scope: updating the owner's unit and the common areas in a single visit, minimizing the number of days tenants need to provide access.

• Multi-unit common-area gaps — Greystones and three-flats frequently have unit-level detectors but nothing in the shared basement, stairwell, or hallway. These gaps are flagged in city inspections and trigger violations.
• ADU coverage missing — Coach house and basement conversions often get a new panel, new circuits, and new appliances but no smoke or CO detection. The ADU is an independently occupied dwelling and requires full coverage.
• Expired units in vacancy-period buildings — Buildings that sat partially vacant during the mid-2010s often have units with original developer-installed detectors from before 2010. We check manufacture dates on every walk.
• Gas appliance CO gaps — Logan Square greystones almost universally run natural gas heat and cooking. Chicago and Illinois require CO detectors within 15 feet of every sleeping room in these homes.
• Knob-and-tube circuit conflicts — Some Logan Square greystones still have original knob-and-tube in portions of the building. Planning a new hardwired smoke circuit requires understanding the existing wiring to avoid connecting to circuits with known deficiencies.

We've worked Logan Square's greystones and multi-unit buildings for decades, and we understand the three-flat's electrical architecture — the shared basement panel room, the separate unit meters, and the plaster walls that make fishing new cable a craft unto itself. Our experience with ADU coach house conversions means we know exactly what Chicago's ADU permit inspector is looking for in terms of fire safety documentation.

The Logan Square Boulevards District designation means we're also attuned to exterior considerations — we plan smoke detector circuit routes through interior walls and never on exterior street-facing surfaces. Our supervising electrician license, permit history, and building-wide completion documentation support landlords, property managers, and individual owners equally.
