New Construction Wiring in Chatham, Chicago
New construction in Chatham's bungalow belt fits into a carefully maintained residential neighborhood. Buyers and builders in this market aren't looking for glass-and-steel statement architecture — they're looking for a well-built, code-compliant, durable home that fits on a block of 1920s-1930s bungalows. The electrical system should match that standard: correctly sized for modern household loads, fully code-compliant from the service entrance to the outlets, and built to last.
For new single-family construction on a standard Chatham lot, that means 200-amp service from ComEd, a modern main panel in the basement, correctly specified circuit counts for kitchen, bathrooms, bedrooms, laundry, and central AC, an EV charger provision in the detached garage, and hardwired smoke/CO throughout. These aren't luxury specifications — they're the baseline for a new home in 2026, and they're what a Chatham buyer should expect to inherit at closing.
Chicago's metallic wiring code applies throughout. New construction in Chatham requires MC cable, EMT conduit, or FMC for all branch circuit wiring. Steel panels and boxes. This code requirement exists citywide and is one of the primary differences between new construction electrical inside Chicago versus the suburbs.
Our New Construction Wiring Process in Chatham
For Chatham new construction, the design phase is focused and efficient. For a standard new single-family on a bungalow-belt lot, we confirm service size (200-amp), panel location (basement, central position for balanced home runs), EV charger provisions (dedicated conduit to the detached garage during rough-in), and the circuit layout per the architectural plan.
For new two-flat construction — increasingly common as investors respond to Chatham's appreciation — design-phase work adds the metering structure: individual 200-amp unit panels, a 400-amp building service, separate ComEd meters, and a house-load circuit. Getting the metering structure right at new construction eliminates the separation project that many two-flat buyers inherit.
Permit submission follows design. We time submission to align with the construction start so rough-in inspection can proceed without delay. Rough-in follows framing; we coordinate with the HVAC contractor to avoid conduit conflicts in the basement mechanical room.
Common New Construction Electrical Needs in Chatham
- Infill single-family new builds — 200-amp service on standard bungalow-belt lots; designed to replace the risk and operational complexity of an aging bungalow's electrical system with a clean, code-compliant installation; EV charger provision in the detached garage standard
- New two-flat construction — 400-amp building service, individual 200-amp unit panels, separate ComEd metering; designed for Chatham's owner-occupant rental investment market; separated from day one to avoid future metering headaches
- 79th Street commercial new builds — Commercial permit track for restaurant, retail, and service commercial new construction; service sizing, commercial plan review, and ComEd commercial service coordination
- Garage and accessory structure wiring — New detached garage construction wiring: lighting, convenience outlets, EV Level 2 charger provision; sub-panel if garage footprint and loads justify it
- Generator-ready provisions — Transfer switch and natural gas stub pre-installed during new construction; Chatham's overhead utility infrastructure creates outage exposure that makes generator-ready provisions a wise investment at new construction cost
- Full appliance circuit provisions — New construction is the right time to get circuit counts right: dedicated circuits for range, refrigerator, dishwasher, microwave, laundry, and central AC; properly designed from the start so tenants and owners aren't tripping breakers
Why Chatham Builders Choose E&P Electric
Chatham's construction market values contractors who treat the neighborhood with respect. Long-term residents have watched over their blocks for decades, and they notice when a contractor works clean, pulls permits, and leaves the job site the way they found it. We do.
For rental investment new construction — new two-flats and infill single-family rentals — we understand what a Chatham investor needs from a new building's electrical system. Correct metering from day one, properly labeled panels, adequate circuit density, and a documented electrical installation that the next buyer can understand. These practical details make a rental investment work over a twenty-year ownership cycle.
Our permit discipline is consistent. We pull permits before work begins, pass rough-in inspections on the first attempt, and close out final inspections cleanly. For a developer on a construction loan, permit reliability directly affects the project's delivery date.
