Home Rewiring in Logan Square, Chicago
Most of the greystones along Logan Boulevard, Kedzie Boulevard, and Palmer Square were first electrified between 1910 and 1925 with knob-and-tube wiring. Many saw a second-generation wire pull in the 1950s, when cloth-insulated rubber cable was threaded alongside original K&T. A third round of partial updates happened in the 1980s and 1990s when kitchens and bathrooms were remodeled — NM cable added to panels that were never designed for it. The result is three generations of wiring, in various states of deterioration, all live and connected.
The knob-and-tube in Logan Square greystones is particularly difficult to address because of the buildings' construction. A three-story greystone with masonry exterior walls, plaster-and-lath interior walls, and three separate residential units has limited chase space, compressed vertical runs, and a shared electrical spine that serves all three units from a common basement. Rewiring one unit often requires assessment and partial work on the entire building's shared infrastructure.
Bungalows on the side streets — especially east of Kedzie between Fullerton and Diversey — are a different scenario. The Chicago bungalow is a one-and-a-half-story brick structure with a tight attic, an unfinished basement, and original knob-and-tube in the walls. These homes are often well-maintained but electrically original. Insurance pressure is the most common trigger for rewiring: carriers are increasingly refusing to renew policies with documented K&T, and many Logan Square bungalow owners have received non-renewal notices in recent years.
Our Home Rewiring Process in Logan Square
Rewiring a Logan Square greystone starts at the basement. The shared service entrance, main disconnect, and meter bank are the foundation of the entire building's electrical system. We assess the service capacity, determine what upgrades the building needs at the service entrance level, and plan how to separate or upgrade unit-level panels while minimizing disruption to tenants.
For owner-occupied greystones being gut-rehabbed, we coordinate with the GC from the framing stage — roughing in new home runs before insulation, placing device boxes before drywall, and sequencing around the kitchen and bathroom trades. For occupied multi-unit greystones where tenants are in residence, we phase the work unit-by-unit, keeping at least one unit's power live at all times.
Logan Square Boulevards District landmark designation affects exterior electrical changes on street-facing facades. We plan meter bank locations, weatherhead placements, and any exterior conduit runs to face the alley or rear yard. When a street-facing change is unavoidable, we submit to Landmarks and design the installation to meet preservation guidelines.
For bungalows, the rewire typically includes a service upgrade from 100A to 200A, full replacement of K&T branch circuits, and new device boxes throughout. The unfinished basement and accessible attic in most Logan Square bungalows make horizontal runs relatively straightforward — access is better here than in finished Victorians.
Common Wiring Issues in Logan Square
- Knob-and-tube under blown-in insulation — The energy crisis of the 1970s prompted many Logan Square homeowners to insulate their attics and walls, sometimes directly over live K&T. Chicago code and most insurers require removal of this insulation from around active K&T before any rewire work proceeds.
- Three-flat metering complexity — Many Logan Square greystones were never properly separated when converted to individually metered units. Shared neutrals, shared circuits, and interconnected feeder arrangements make a full building assessment essential before scoping any unit-level rewire.
- Masonry walls limiting fishing routes — Unlike a wood-frame building where fishing through a wall cavity is straightforward, the masonry exterior walls of a greystone offer no cavity to fish through. All new wiring in exterior walls must run in surface-mounted or embedded conduit, or through interior partitions.
- Original fuse panels — Greystones frequently still have their original fuse boxes at the unit level. These must be replaced with modern breaker panels as part of any rewire. Chicago's electrical code prohibits extending new wiring on fuse circuits without panel replacement.
- ADU coach house wiring — With the city's ADU legalization, Logan Square coach house conversions have proliferated. Every ADU needs independent electrical service — a new feeder from the main building or a separate service drop — and a complete permit package.
Why Logan Square Residents Choose E&P Electric
Logan Square greystone rewiring is a project that requires both technical depth and neighborhood knowledge. We've pulled permits at the Chicago Department of Buildings for greystone rewires dozens of times, and we understand how to scope a permit that covers the building-level service upgrade alongside the unit-level branch-circuit replacement. Our owner holds the Chicago Supervising Electrician License and has worked the Logan Square market for over 30 years.
We understand the Logan Square Boulevards District landmark process and design our exterior electrical work to meet preservation guidelines on the first submission — not after a rejection and redesign. We also coordinate with the ADU permit process and have submitted electrical plans for coach house conversions under the city's ADU pilot program.
We're on the call lists of GCs who work the Milwaukee Avenue corridor — the craft breweries, coffee shops, and residential buildings being renovated in the blocks between Armitage and Diversey.
