Electrical Services in Clarendon Hills

Yes — the Village of Clarendon Hills requires a permit for all electrical work beyond simple device replacements. This includes panel upgrades, new circuit installations, EV charger wiring, basement finishing electrical, kitchen and bathroom remodel wiring, and any work that opens walls or changes the system’s capacity. Permits are issued through the Community Development Department at 1 N Prospect Avenue (630-286-5410). The Village adopted updated building codes effective February 1, 2026, so any current work must comply with the new standards. Unpermitted electrical work is a known issue during home sales in Clarendon Hills and can delay or kill a transaction. Energy Co. handles the permit application and schedules all required inspections as part of every permitted project.

The Village of Clarendon Hills adopted updated model building codes effective February 1, 2026. For electrical work, this means all new and renovation projects must comply with the current NEC edition adopted by the Village, which includes expanded AFCI breaker requirements for living spaces and updated GFCI coverage rules. If you started a project before the code update and it’s still in progress, the applicable code depends on when your permit was issued. We stay current with Clarendon Hills’s adopted standards and confirm the applicable version with the Community Development Department before starting any permitted project.

Once a permit is issued by the Village’s Community Development Department, inspections must be requested by the contractor — not the homeowner. The Village requires inspection requests to be submitted before 2 pm for next-business-day scheduling, and requests left by voicemail are not accepted. When the inspector approves the final work, the Village issues either a Certificate of Occupancy or a Certificate of Compliance. The permit construction deposit is not released until that certificate is issued and any disturbed parkway or site areas are restored. Energy Co. manages the entire inspection coordination so you don’t have to track deadlines or inspection windows.

Yes — ComEd is the electric utility for Clarendon Hills. For panel upgrades or service entrance work, we coordinate with ComEd to schedule a meter pull before the work begins and meter reconnection after the Village inspection passes. ComEd’s scheduling for residential accounts typically runs three to five business days from the request. We handle the ComEd coordination on your behalf so the project moves forward without you managing two separate timelines — the utility and the Village permit process run in parallel when handled correctly.

A Level 2 EV charger draws 40–50 amps continuously, which is a significant addition to any panel’s load. Many Clarendon Hills homes with 150-amp service and a full slot count can accommodate a charger, but some — particularly those with electric heating, central AC, and high-draw kitchen appliances already on the panel — may need a service upgrade first. We perform a load calculation before recommending anything. If your panel supports it, we add the dedicated 240-volt circuit and install the charger in one visit. If an upgrade is needed, we handle both as a single project so you’re not paying for two separate mobilizations.

Kitchen remodels in Clarendon Hills homes frequently uncover electrical that was installed to older standards. When walls open up, it’s common to find outlets without GFCI protection within six feet of the sink, a single 15-amp circuit serving multiple countertop outlets when current code requires at least two dedicated 20-amp circuits, and range or microwave circuits that are undersized for modern appliances. We bring the kitchen’s electrical up to current Village code as part of the remodel, including adding dedicated circuits for the refrigerator, dishwasher, and disposal where they don’t exist. The permit covers all of this work under a single application.

AFCI (arc-fault circuit interrupter) breakers are required under current Illinois and Clarendon Hills code for bedrooms, living rooms, hallways, and most other living spaces in new construction and permitted renovation work. Homes built before 2014 typically don’t have them. If you’re doing a permitted remodel or adding circuits in living spaces, AFCI protection will be required on those circuits by the Village inspector. Retrofitting the rest of the home isn’t always mandatory outside of permitted work, but it’s a meaningful safety upgrade — AFCI breakers detect arcing inside walls before it becomes a fire, which is particularly valuable in a 40-year-old home with decades of wiring modifications.

In Clarendon Hills’s real estate market, where median home values exceed $600,000, buyer inspectors look closely at electrical systems. The most common red flags — Federal Pacific or Zinsco panels, ungrounded two-prong outlets throughout, missing GFCI protection, and unpermitted wiring modifications — can trigger price renegotiations or kill a sale entirely. A pre-listing electrical inspection and targeted upgrades remove those objections before the buyer’s inspector finds them. We provide written documentation of all work completed and copies of Village permits and inspection approvals, which you pass along to the buyer as part of the disclosure package.

Yes — basement finishing is one of the most common projects we handle for Clarendon Hills homeowners. A typical basement finish requires new branch circuits run from the panel, dedicated circuits for a home theater or office setup, GFCI outlets in any wet bar or bathroom, AFCI breakers on circuits serving sleeping or living areas, interconnected smoke detector wiring tied to the home’s existing alarm system, and egress lighting on the stairwell. We pull the Village of Clarendon Hills electrical permit and coordinate all inspections. If your panel doesn’t have enough open slots for the new circuits, we add a subpanel or upgrade the main panel as part of the same project.

A pre-purchase electrical inspection is an independent review of a home’s electrical system conducted before closing. In Clarendon Hills, where many homes are 40-plus years old and have changed hands multiple times, it’s one of the most valuable steps a buyer can take. We inspect the panel’s age, brand, and capacity; the condition of visible wiring in the basement and attic; GFCI and AFCI coverage; grounding; and outlet condition throughout the home. You receive a written report with findings ranked by urgency and estimated cost to address. Most buyers use this to negotiate corrections before closing or to budget for the work in the first year of ownership.

Yes — we serve commercial clients in Clarendon Hills, including businesses in the Ogden TIF District and the 55th Street Sub-Area. Commercial electrical work we handle includes tenant improvement wiring for new business build-outs, panel upgrades for businesses with growing equipment loads, lighting installations and retrofits, and electrical safety inspections for lease renewals and certificate of occupancy applications. We coordinate with the Village’s Community Development Department for all commercial permits and schedule inspections to keep your build-out timeline on track.
