Residential Electrical Safety Inspection Checklist: What Pros Look For

Electrical safety inspections are an easy upsell on every service call and a great way to build trust. Here's a systematic approach that takes 30-45 minutes and consistently generates $500-2,000 in follow-up work.

Why Offer Electrical Safety Inspections?

Home inspectors flag electrical issues but aren't electricians — you'll find things they miss
Insurance companies sometimes require them for older homes
Homebuyers want peace of mind (especially on homes built before 1990)
Each inspection typically generates 3-5 actionable findings

Charge $150-250 for a standard inspection. The inspection usually pays for itself in follow-up work.

The 10-Point Service Panel Check

[ ] Panel brand: Federal Pacific, Zinsco, or Pushmatic? → Immediate replacement recommendation
[ ] Panel condition: Rust, water stains, scorch marks? → Flag as urgent
[ ] Breakers: Double-tapped? Oversized for wire? Wrong brand? → Correct
[ ] AFCI/GFCI: Present where required? → Note missing protection
[ ] Grounding: GEC visible? Ground rods accessible? Bonding jumper to water pipe?
[ ] Neutral/ground: Separated in sub-panels? Bonded at main only?
[ ] Aluminum wiring: Present? If yes, check for proper AL/CU connections and anti-oxidant
[ ] Wire condition: Insulation intact? No cloth-insulated wiring touching?
[ ] Clearance: 30" wide × 36" deep working space clear? (NEC 110.26)
[ ] Labeling: Circuits properly identified? → Label any unknowns

Room-by-Room Quick Checks

Kitchen: - GFCI on all countertop receptacles? (NEC 210.8(A)(6)) - Two 20A small appliance circuits minimum? (NEC 210.52(B)) - Receptacles within 24" of any countertop edge? - No receptacles face-up in countertops?

Bathroom: - GFCI protection on all receptacles? (NEC 210.8(A)(1)) - 20A circuit dedicated to bathroom(s)? (NEC 210.11(C)(3)) - Exhaust fan working and vented outside?

Bedrooms & Living Areas: - AFCI protection present? (NEC 210.12) - Receptacles spaced every 12 feet max? (NEC 210.52) - Smoke detector present in each bedroom? (many jurisdictions) - No receptacles covered by furniture with cords pinched?

Outdoors: - All exterior receptacles GFCI protected? (NEC 210.8(A)(3)) - Weather-resistant covers (in-use bubble covers where needed)? - Outdoor lighting working and rated for wet location? - Service drop: Clearance over driveway (10 ft), over yard (12 ft)?

5 Most Common Findings (and What to Charge)

1. Missing GFCI protection ($145-180/receptacle replacement) — most common issue in pre-2000 homes 2. Double-tapped breakers ($75-125 to add a breaker or pigtail) — quick fix, high value 3. Federal Pacific / Zinsco panel ($2,500-3,500 replacement) — safety critical, always recommend 4. No AFCI protection ($45-60/breaker for retrofit) — required in most living spaces 5. Ungrounded 3-prong outlets ($85-180 for GFCI replacement with "No Equipment Ground" labeling)

Report Template

Always provide a written report with photos. Structure it as: 1. Immediate Hazards (fix now) 2. Code Violations (fix soon) 3. Recommendations (improvements, not required)

Don't be alarmist, but don't downplay real hazards. "This Federal Pacific panel has a known defect where breakers fail to trip during an overload. Approximately 2,800 fires per year are attributed to these panels. I strongly recommend replacement."

How to Sell the Inspection

"While I'm here for the panel upgrade, I can do a whole-home electrical safety inspection for $195. It takes about 30 minutes and I'll give you a written report with photos. Most homeowners discover 3-5 things they didn't know about. No pressure — just good information."

Most customers say yes.
