Home Electrical Wiring Cost: Rewiring, New Circuits & Panel Work

Electrical work has a wider price range than almost any other trade because the scope varies so dramatically — from a $200 outlet addition to a $20,000 full rewire. Understanding how electricians price work, and what actually requires a licensed professional, prevents both overpaying and the much worse outcome of underpaying.

Common Electrical Projects and Cost Ranges

Labor rates for licensed electricians run $75–$150/hour depending on region, with most residential jobs billed at a flat rate or time-and-materials with a service call minimum.

Panel Upgrades: When and Why

A 100-amp electrical service was standard for homes built before the 1980s. Modern households — with EV chargers, heat pump HVAC, induction ranges, and multiple home offices — routinely exceed that capacity. Signs you need an upgrade: breakers tripping frequently, lights dimming when appliances run, inability to add new circuits, or plans for EV charging or HVAC electrification.

A 100A to 200A panel upgrade runs $1,500–$3,500 for the panel work itself. If the utility service entrance (the line coming from the street to your meter) also needs upgrading, add $1,000–$3,000 — this requires coordination with your utility company and often takes 2–6 weeks for scheduling.

Federal Pacific and Zinsco panels are a special case. These brands, installed widely from the 1950s–1980s, have documented breaker failure issues. If you have one, replacement isn't optional — it's a safety issue that also affects insurance coverage and home sale transactions. Budget $2,000–$4,500 for replacement including inspection and permit.

Full Rewires: What Triggers Them

Full house rewiring is required when: the home has knob-and-tube wiring (pre-1940s), aluminum branch circuit wiring (1965–1973), cloth-insulated wiring that is crumbling or showing active degradation, or insufficient circuits to support modern load demands.

Knob and tube (K&T) is ungrounded, lacks the capacity for modern loads, and cannot be insulated over safely. Most insurers won't cover homes with active K&T, and buyers can't get mortgages on them. Replacement is unavoidable if you're selling or updating the coverage.

Aluminum branch wiring (distinct from aluminum service entrance cables, which are still standard) was used briefly in the late 1960s–early 1970s and has connection integrity issues that create fire risk at outlets and switches. CPSC-approved remediation options include pigtailing with copper at all connection points (CO/ALR rated devices) — this is cheaper than full replacement and acceptable to most insurers.

What Requires a Permit

Virtually all electrical work beyond simple device replacement (switching out an outlet or switch for a like-for-like replacement) requires a permit in most jurisdictions. This includes: new circuits, panel work, adding outlets in new locations, and EV charger installation.

Unpermitted electrical work is a serious liability — it can void your homeowner's insurance coverage for related claims, and it's a disclosure obligation that can complicate or derail a home sale. Licensed electricians pull permits as part of the job. If a contractor offers to skip permits to save you money, that's a risk transfer to you, not a savings.

EV Charger Installation

A Level 2 (240V) EV charger requires a dedicated 50-amp circuit from your panel. The total installed cost runs $500–$1,500 depending on panel location relative to the garage, whether the panel has capacity, and local permit requirements.

If your panel doesn't have a free 50-amp slot or sufficient capacity, add $500–$2,000 for panel work. Some homes with 100A service can't support a 50A EV circuit without a panel upgrade.

Smart chargers (Wi-Fi, scheduling, energy monitoring) add $200–$600 to the equipment cost but pay back in off-peak charging flexibility.

Aluminum Service Entrance vs. Branch Wiring

A point of frequent confusion: the large cables running from your meter to your main panel are service entrance conductors and are commonly aluminum even in modern construction — this is normal, code-compliant, and not a safety concern. The concern with aluminum is in branch circuit wiring (the smaller wires running to outlets, switches, and fixtures). These are the ones that had connection integrity problems in the 1960s–70s aluminum wiring.

Have an electrician clarify which type you have. The distinction matters significantly for the remediation approach and cost.

How to Evaluate Electrical Bids

Electrical bids should specify: wire gauge for each circuit, panel amperage and brand, permit inclusion, inspection coordination, and warranty on workmanship. Avoid any contractor who offers to complete panel or circuit work without permits.

Get two or three quotes on any job over $1,000. Labor pricing varies meaningfully by market, and so does scope interpretation — what one electrician includes in a "panel upgrade" another might bill separately.
