Staying up to date with the latest electrical code requirements isn’t just about passing inspections — it’s about keeping your home or commercial project safe, insurable, and future-proofed. In 2025, Chicago introduced key changes to its electrical code that affect residential and commercial installations alike.
At Voltek Electric, we specialize in delivering compliant, up-to-code electrical work throughout Arlington Heights, Glenview, and the greater Chicago area. Here’s everything you need to know about the new requirements.
Why Code Compliance Matters
Failing to follow current electrical code can result in:
- Failed inspections and costly rework
- Delays in permit approval
- Voided insurance claims
- Safety hazards (fire, electrocution)
Whether you’re doing a remodel, service upgrade, or new build, code compliance is critical.
🔧 Overview of 2025 Chicago Electrical Code Updates
1. Mandatory AFCI & GFCI Expansion
- AFCI protection now required in all habitable rooms, including dens and finished basements
- GFCI required for all 120V outdoor outlets and unfinished spaces
2. EV Charger Readiness in New Builds
- All new residential construction must include a dedicated 40-amp circuit for future EV charger install
- Commercial parking lots with 5+ spaces must designate 10% as EV-ready
3. Metal Conduit (EMT) Requirements Reinforced
- Residential wiring in Chicago must still be run in EMT or metallic raceways — Romex is not permitted
- Stricter inspections on connector bonding and conduit support
4. Surge Protection Mandate
- Whole-home surge protection devices now required on new service panel installations
5. Service Disconnect Rule (NEC Alignment)
- New requirement: service disconnect must be located outside or nearest point of entry
- Aimed at improving firefighter safety
6. Tamper-Resistant Outlets Expanded
- Required in all habitable areas, not just child-accessible rooms
7. Energy Efficiency & Smart Tech Provisions
- Lighting circuits must accommodate smart dimmers or automation in new construction
- Commercial jobs must meet new energy-efficient lighting requirements
Permit & Inspection Impact
Chicago’s Department of Buildings has tightened enforcement in 2025:
- More surprise inspections on mid-sized remodels
- Delays for non-compliant panel upgrades
- Requirement to submit load calculations and AFCI plans for approval
Voltek Electric handles all permitting, submittals, and pre-inspection prep for you.
How This Affects Homeowners and Contractors
| Project Type | What to Watch For |
|---|---|
| Panel Upgrades | Must include surge protection + bonding |
| Basement Remodel | AFCI & GFCI protection now required |
| Detached Garages | Must meet conduit + GFCI + disconnect rules |
| Kitchen Renovations | Tamper-resistant + AFCI + smart-ready |
If you’re hiring an unlicensed electrician or DIYing, expect permits to get flagged.
