A whole-home electrical safety inspection gives you a clear picture of what is safe, what is outdated, and what should be repaired soon. STS Electric performs home electrical inspections across Chicago for pre-purchase due diligence, rental turnovers, older homes, and troubleshooting after flickering lights or tripping breakers. We work as licensed electricians, not as code enforcement, but we follow Chicago and NEC standards when we evaluate your system and document findings you can act on.
When to Schedule a Home Electrical Inspection
Different situations call for the same thorough process with different priorities.
Pre-purchase and pre-listing
Buyers want to know if the panel is adequate, if unpermitted work exists, and if major upgrades are coming. Sellers use inspections to fix deal-breakers before listing. We focus on safety defects, capacity limits, and items that commonly appear on Chicago home inspection reports.
Rental and multi-unit turnover
Landlords schedule inspections after tenant change, before major renovations, or when adding units. We check smoke and CO coverage, GFCI protection in required locations, and common areas for exposed splices or overloaded circuits.
Older Chicago homes
Bungalows, two-flats, and greystones often have mixed wiring ages, prior DIY work, and panels that have been expanded piecemeal. We flag cloth-insulated conductors, ungrounded outlets, missing AFCI or GFCI where now required, and signs of aluminum connections that need proper treatment.
After symptoms appear
Flickering lights, warm faceplates, buzzing from the panel, or breakers that trip without obvious cause deserve inspection before they escalate. If you have an urgent safety concern, our 24/7 emergency electrical service can stabilize the situation first, then schedule a full review.
What STS Electric Checks On Site
Every inspection is tailored to the home, but our standard scope covers the items buyers, insurers, and prudent owners care about most.
Main panel and subpanels
We open accessible panels with safe procedures, note manufacturer and amperage, look for double-tapped breakers, scorch marks, missing knockouts, and improper bonding. Corrosion, water intrusion, and Federal Pacific or Zinsco panels receive explicit mention when present. Learn more about panel life and upgrades on our electrical panels.
Grounding and bonding
Effective grounding paths protect people and equipment. We verify grounding electrode connections where visible, main bonding jumper presence, and bonding of gas piping or other systems when applicable. Missing or compromised grounding is a high-priority finding.
GFCI and AFCI protection
Kitchens, bathrooms, garages, exteriors, and laundry areas need GFCI protection per current standards. Bedrooms and many living areas require AFCI protection on newer circuits. We test accessible devices and note gaps. Remediation may be as simple as breaker or device replacement, or it may require new circuits in older homes.
Wiring type and condition
We document visible wiring methods: Romex, conduit, knob-and-tube remnants, cloth-insulated conductors, and aluminum branch circuits. Attics, basements, and unfinished areas get extra attention for splices without boxes, damaged insulation, and DIY extensions. For cloth-insulated wiring questions, see our overview of electrical wiring concerns in older Chicago buildings.
Outdoor, detached, and service equipment
Exterior receptacles, hose bib outlets, deck lighting, and garage feeds are common failure points. We inspect weatherproof covers, in-use ratings, and conduit integrity. In Chicago, exterior and garage runs often use EMT or rigid conduit; we note rust, loose fittings, and unsupported runs.
Smoke and carbon monoxide detection
We confirm that hardwired or battery smoke detectors are present in required locations and note interconnection where visible. While we are not fire alarm certifiers, missing or outdated detectors appear in our report as life-safety recommendations.
What the Inspection Is Not
A visual and functional inspection does not destroy walls or audit every hidden junction box. We do not represent the City of Chicago or pass official code enforcement. If we see evidence of serious hazards, we tell you immediately and discuss whether power should be limited to certain circuits until repairs are made.
When repairs require permits, STS Electric pulls them as part of the repair scope. Chicago work often means conduit, proper boxes, and inspection scheduling familiar to our crews.
What to Expect: Process, Report, and Timeline
Most single-family inspections take a few hours depending on size, access, and panel count. We ask you to clear panel areas, attic paths, and basement ceilings where safe. You receive a written summary grouped by priority:
Immediate safety items that should be corrected before occupancy or closing. Short-term repairs that reduce fire and shock risk within weeks. Planning items such as panel upgrades, rewiring projects, or added circuits for modern loads.
Photos support major findings when helpful. We explain terms in plain language so agents, attorneys, and contractors share the same facts. If you need repairs, we can often quote the same findings through our electrical repair service without a second diagnostic visit.
After the Inspection: Next Steps
Not every finding requires an emergency spend. We help you sequence work: fix shock and fire risks first, then capacity upgrades for EV chargers or additions, then convenience upgrades. Major panel or service work may tie to other projects you already planned.
Keep the report for insurance records and future renovations. When you sell, buyers appreciate documented repairs from a licensed contractor.
How Inspection Findings Turn Into Repairs
Not every item requires the same urgency. We rank findings so you can budget and schedule with confidence. Shock hazards, missing covers on live parts, and compromised service equipment top the list for immediate correction. GFCI and AFCI gaps, outdated two-prong outlets in kitchens and baths, and unsupported conduit in garages usually follow as short-term work.
Planning-level items include service size increases, full rewiring of cloth or knob-and-tube sections, and subpanel additions for finished basements. We tie those recommendations to how you use the home: EV charging, home office load, rental turnover, or aging in place. You receive repair options in writing rather than a verbal list that is easy to forget after closing.
Chicago-Specific Considerations
City inspections and Chicago wiring practice differ from suburban Romex-only retrofits. Many homes use metal conduit in parts of the structure even when other areas have cable. Our inspectors note where conduit is damaged, where fittings are missing, and where prior owners mixed methods incorrectly. Permit history may not exist for older work; we document what is visible and what should be opened only with a renovation scope.
Three-flat and courtyard building owners should mention unit metering and common hall lighting during scheduling. Access to multiple panels, locked rooms, and tenant coordination affects timing. We work with property managers regularly and can return for phased repairs if tenants need notice.
Condo buyers should ask the association about recent meter or service projects in the building. Our inspection still covers unit panels and branch wiring even when the association maintains common service equipment.
