Summary:
The 2023 NEC changes became effective July 29, 2024, bringing significant updates to electrical safety requirements. These aren’t minor tweaks. They represent substantial shifts in how electrical work must be performed and what safety devices are required.
The most significant changes focus on enhanced protection against electrical fires and improved safety standards. GFCI protection has been expanded to include wall-mounted ovens, counter-mounted cooking units, clothes dryers, microwave ovens, and any cord-and plug-connected appliance in kitchens, not just on countertops.
For Chicago homeowners, these updates build upon the city’s already strict electrical requirements. Chicago adopted its current electrical code in September 2017 based on the 2017 National Electrical Code, which became mandatory March 1, 2018. The 2024 updates add additional safety layers to this foundation.
Ground Fault Circuit Interrupter protection has been dramatically expanded in the 2024 updates. If you’re renovating your kitchen or laundry room, these changes will directly impact your project costs and timeline.
A major GFCI update removes the distance limitation between kitchen receptacle outlets and the sink. Previously, only outlets within six feet of the sink required GFCI protection. Now, all kitchen receptacles need this protection regardless of their distance from water sources.
The expansion extends beyond just outlets. GFCI protection now applies to major appliances including wall-mounted ovens, counter-mounted cooking units, clothes dryers, and microwave ovens. This means if you’re replacing any of these appliances, the electrical work must meet the new GFCI requirements.
For Chicago homeowners, this creates a unique situation. City law already prohibits homeowners from doing their own electrical work due to potential for electric shock or fire hazard—only licensed electrical contractors can perform electrical installations. The new GFCI requirements reinforce why this restriction exists.
The practical impact? Higher costs for appliance replacements and kitchen renovations. But the safety benefits are substantial. The U.S. Consumer Product Safety Commission reports that electrical receptacles are involved in 5,300 fires every year, causing forty deaths and more than 100 consumer injuries. GFCI protection significantly reduces these risks.
When planning any kitchen or laundry work, budget for potential electrical upgrades to meet these new requirements. Your licensed electrician will assess your current system and determine what modifications are necessary for compliance. Don’t get caught off guard by unexpected electrical costs that could derail your renovation timeline.
Arc Fault Circuit Interrupters represent one of the most important safety advances in electrical protection. The 2024 updates have expanded where they’re required, and the implications for Chicago homeowners are significant.
AFCI branch circuit protection now extends to sleeping quarters in fire stations, police stations, ranger stations and similar locations. While this might seem irrelevant to homeowners, it signals the increasing recognition of AFCI importance in fire prevention.
For residential applications, the statistics are sobering. The majority of fires caused by electrical wiring flaws occur in the bedroom, which is why AFCIs are professionally installed in bedrooms and the National Electric Code now requires AFCIs for bedroom circuits in new residential construction.
Chicago homeowners with older homes should understand that while AFCI requirements primarily apply to new construction and major renovations, upgrading existing bedroom circuits provides significant safety benefits. Each year in the United States, arcing faults are responsible for starting more than 28,000 home fires, killing and injuring hundreds of people, and causing over $700 million in property damage.
The technology works by detecting dangerous arcing conditions that standard breakers miss. These advanced new safety devices recognize dangerous conditions that are not detected by standard breakers. When an AFCI detects an arc fault, it immediately shuts off power to prevent fire ignition.
If you’re adding circuits for home offices, finishing a basement, or doing major electrical work, AFCI protection will likely be required. The investment pays dividends in safety and can potentially reduce insurance costs. Many insurance companies offer discounts for homes with enhanced electrical safety features.
We can assess whether your existing electrical panel can accommodate AFCI breakers or if panel upgrades are necessary. In Chicago’s older housing stock, panel upgrades are often needed to support modern safety devices and electrical loads. Factor this into your project planning from the start.

Chicago’s electrical requirements go far beyond standard National Electrical Code provisions. The Chicago Electrical Code only applies to Chicago itself, however many suburbs in the area require EMT for dwelling units, and Chicago has specific rules like requiring service disconnecting means to be installed in the basement or first floor, not exceeding 5 feet from the point of entry.
The city’s conduit requirements create unique challenges and costs. In Cook County, Illinois (Chicago), it’s illegal for even a resident homeowner to touch their home’s electrical system beyond replacing a lightbulb, and Cook County has very strict electrical codes, one of the biggies being that everything must be conduit.
Under the new Chicago Energy Transformation Code, every major renovation must meet wiring ampacities and raceway sizes that anticipate full electrification, and any new residential parking stalls must include conduit stubs for Level 2 EV chargers. This forward-thinking approach prepares homes for future electrical demands but adds complexity to current projects.
Chicago’s metal conduit requirement sets it apart from most other cities and creates both significant benefits and challenges for homeowners planning electrical work.
The reason for Chicago’s EMT requirement for residential wiring is to minimize the chance of fire. This requirement stems from the city’s history and commitment to fire safety. The requirement has always been based on fire concerns, making it a fundamental safety measure rather than just regulatory preference.
The practical impact means virtually all electrical work requires professional installation. A metal raceway wiring system will almost always require a professional to install and modify, while cable type wiring systems are more DIY and hack friendly, and therefore easier to screw up and presumably cause fires.
For homeowners, this translates to higher costs but significantly improved safety. Metal conduit provides superior protection for electrical wires, reducing fire risk and improving system longevity. The conduit also makes future modifications easier since new wires can often be pulled through existing conduit runs.
When planning electrical work, understand that Chicago’s conduit requirements affect both labor and material costs. About 3/4 of the actual work is planning conduit design, planning fill, cubic-inching the junction boxes, fitting the conduit and boxes, working out run lengths, and getting pull strings into the conduit. This complexity requires experienced professionals familiar with Chicago’s specific requirements.
The conduit requirement also affects renovation timelines. Running new conduit through existing walls requires careful planning and often more invasive work than cable installations. However, the long-term benefits in safety and system reliability make this investment worthwhile.
If you’re buying a home in Chicago, have the electrical system inspected by a professional familiar with local codes. Older homes may have grandfathered wiring that doesn’t meet current standards. Understanding these issues before purchase can prevent costly surprises during future renovations.
Chicago’s 2022 Energy Transformation Code contains several Chicago-specific requirements that apply regardless of the compliance path selected. These requirements represent the city’s commitment to electrification and energy efficiency—and they’ll impact your electrical planning whether you’re ready or not.
The most immediate impact for homeowners involves EV charging preparation. At least 20 percent of total parking spaces must be either EVSE-ready or EVSE-installed, with EVSE-installed meaning having a 40-ampere, 208- or 240-volt dedicated branch circuit terminating at a Level 2 electric vehicle charging unit adjacent to the parking space.
Even if you don’t currently own an electric vehicle, new construction and major renovations must anticipate future EV charging needs. EVSE-ready requirements were added to the Chicago Zoning Ordinance in 2019 and apply to projects where the first permit application was started on or after November 1, 2020.
For single-family homes, this means ensuring your electrical service and panel can handle the additional 40-amp load for EV charging. Many older homes require service upgrades to meet these requirements, particularly when combined with other electrical modernization needs.
The code also addresses all-electric readiness. In new dwelling units with individual fuel-gas-fired appliances for indoor cooking, hot water heating, or clothes drying, adequate electrical capacity and wiring must be provided to make it easy to switch out the gas-fired appliance with an equivalent all-electric appliance in the future without additional construction or electrical work.
This forward-thinking approach means electrical systems must be sized and designed for potential future conversion to all-electric operation. While you might currently use gas for heating or cooking, your electrical system must be capable of handling electric alternatives without major modifications.
Solar readiness adds another layer of complexity. At least 40 percent of available roof area must be designated as a solar-ready zone and designed with structural capacity to accommodate additional weight, construction documents must show a reasonable path for future installation of conduit from the solar-ready roof zone to the main electrical service panel, and a permanent certificate with information about the solar-ready zone must be installed near the main electrical panel.
These requirements significantly impact electrical system design and costs but position homes for future energy independence and efficiency. When planning major electrical work, discuss these requirements with us to ensure compliance and avoid costly retrofits later. The investment in future-ready electrical infrastructure pays dividends when technology adoption accelerates.
The 2024 electrical code updates represent significant changes that directly impact Chicago homeowners’ renovation and maintenance decisions. Understanding these requirements before starting any electrical project can save thousands in unexpected costs and delays.
With home electrical fires accounting for an estimated 51,000 fires each year, nearly 500 deaths, more than 1,400 injuries, and $1.3 billion in property damage, these code updates aren’t just regulatory requirements—they’re essential safety measures protecting your family and investment. The enhanced GFCI and AFCI requirements, combined with Chicago’s unique conduit and energy transformation standards, create a comprehensive safety framework.
Chicago’s electrical requirements demand professional expertise. Due to the potential for electric shock or fire hazard, only Electrical Contractors licensed by the City of Chicago can perform electrical installations.
