The cost to run electrical service to a detached shed varies widely based on distance from the main panel, the required amperage, conduit and trenching needs, and local permit rules. Typical projects fall in a broad range, from simple extensions to fully wired, code-compliant setups with outlets, lighting, and a subpanel.
Key factors are distance, amperage, conduit type, and permitting requirements, which together drive both material and labor costs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Electrical Run (materials) | $600 | $2,000 | $6,000 | Includes conduit, cable, meters, and disconnect where required |
| Labor & Install | $500 | $2,500 | $6,000 | Varies by distance and complexity |
| Permits & Inspections | $100 | $500 | $2,000 | Depends on local jurisdiction |
| Trenching & Backfill | $250 | $1,000 | $3,000 | Includes active soil removal |
| Subpanel & Breakers | $350 | $1,200 | $4,000 | With disconnect and mounting |
| Other Materials & Permits | $150 | $800 | $2,500 | Conduit fittings, weatherproof boxes, GFCI/AFCI |
Overview Of Costs
Total project ranges and per-unit estimates help buyers size a shed electrical upgrade quickly. When the shed is within 50 feet of the main panel and only a 120/240V circuit is needed, costs lean toward the lower end. If the distance grows beyond 100 feet, 240V service is typical, and a subpanel or meter disconnect becomes more common, driving the high end.
Assumptions: single-phase 120/240V service, standard rigid or PVC conduit, typical suburban permits, basic weatherproofing, and no extensive landscaping impact. Assumptions: region, specs, labor hours.
Per-unit costs commonly appear as $/ft for conduit and cable, and $/amp for service capacity upgrades. The following covers typical project ranges for a detached shed electrical run in the U.S.

| Warranty & Overhead | $0 | $150 | $600 | Contractor margin and workmanship guarantee |
| Contingency | $0 | $250 | $1,000 | Unforeseen obstacles |
Assumptions: region, specs, labor hours.
What Drives Price
Distance from the main panel is the dominant driver. Short runs under 50 feet with a simple 120V or 240V circuit require less trenching and smaller conduit. Longer runs over 100 feet often demand larger conduit and a dedicated subpanel, increasing both material and labor costs.
Amperage and service type influence price, with 60A or 100A or 125A service requiring different panel and disconnect components. For shed power, many homeowners opt for 60–100 amps to support outlets, lights, a small HVAC, or a workshop machine.
Permits and local codes vary by jurisdiction; some areas require inspections and wiring up to code with AFCI/GFCI protection, which adds to the price.
Ways To Save
Plan ahead by batching electrical work with other exterior projects to reduce mobilization costs. Ask a licensed electrician for a two-stage plan: (1) core feed to the shed, and (2) upgrades or added circuits in a follow-up phase if needed.
Consider off-peak scheduling or requesting written estimates from multiple licensed electricians to compare labor rates.
Regional Price Differences
Costs vary by region due to labor rates, permit fees, and material availability. In the Northeast, trades tend to be higher, while the Midwest may offer mid-range pricing. The West can be higher still in some metro areas, and rural regions often have lower labor costs but longer travel charges.
For context, a 60–100 amp feed with a subpanel can range: Northeast about $2,600-$7,200, Midwest $2,000-$6,000, West $2,800-$7,500. Regional delta: +/- 15–25% versus national averages.
Labor & Installation Time
Labor time correlates with distance, soil type, and trench depth. A typical trench for an above-ground run under 50 feet may take a day; longer or deeper trenches can extend to two or more days. Per-hour rates for licensed electricians generally run $65-$120/hour, with journeymen on the higher end and apprentices contributing at lower rates.
In projects with a subpanel, expect 1–2 additional days for wiring, panel mounting, and testing. Span: data-formula=”labor_hours × hourly_rate”> and includes system testing for faults and code compliance.
Permits, Codes & Rebates
Permits are mandatory in most jurisdictions and add to the upfront cost. Typical permit fees range from $100 to $800, with inspections possibly adding another $100–$500. Some regions offer rebates or credit for energy-efficient upgrades even for outbuildings, though these are less common for simple feeder runs.
Factor in potential service upgrades in the main panel if the shed’s load is substantial. A full electrical upgrade in the main panel can add $1,000–$3,000 to the project, though this is not always required for basic shed power.
