Homeowners typically pay to extend electrical service from the main panel to a detached garage. The price is driven by distance, conduit type, required amperage, trenching or trenchless work, and local permit rules. This article breaks down the cost to run electricity to a detached garage and provides realistic price ranges for common scenarios.
Assumptions: suburban installation, standard 60-amp to 100-amp service, and midwest or southeast labor rates with typical permits.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Run length | $8-$12 per ft | $12-$18 per ft | $18-$28 per ft | One-way distance from main panel to detached garage |
| Conduit type | $1.50-$3.50/ft | $2.50-$5.00/ft | $5.00-$8.00/ft | PVC or metallic conduit; exterior grade |
| Wire gauge and amperage | $300-$900 | $500-$1,800 | $1,800-$4,500 | 60-amp or 100-amp feeders |
| Trenching or boring | $2-$8 per ft | $5-$12 per ft | $12-$20 per ft | Soil and obstacle dependent |
| Digging permits and inspections | $50-$100 | $150-$350 | $400-$700 | Local jurisdiction fees |
| Utility service connection | $0-$300 | $100-$600 | $1,000-$2,000 | Meter socket, service drop, or upgrade fees |
| Labor to install and connect | $25-$60/hr | $45-$90/hr | $100-$150/hr | Journeyman electrician rates vary by region |
Typical Total Price For Underground Or Overhead Conduit
Most projects fall in the range of $2,500 to $8,500 for a 40- to 100-foot run, including permits and labor. A shorter run with a 60-amp feeder and overhead path may land closer to the $2,500-$4,000 range, while a longer, underground installation with a 100-amp feeder and trenching can reach $6,000-$9,000 or more. Expect total costs to cluster around midpoints where distance is moderate and permit processes are routine.
Major Cost Components Of Electrical Run
The quote can be broken into four to six primary parts: conduit and wiring, trenching or boring, permit and inspection, service connection or meter work, labor, and any needed trench restoration. Assumptions: standard 60-amp feeder, steel or PVC conduit, and one-point inspection.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Conduit and wiring | $1.50-$3.50/ft | $2.50-$5.00/ft | $5.00-$8.00/ft | Cost depends on conduit type and outdoor exposure |
| Trenching/boring | $2-$8/ft | $5-$12/ft | $12-$20/ft | Soil hardness and obstacles affect price |
| Permits and inspections | $50-$150 | $150-$350 | $400-$800 | Regional variance |
| Service connection and meter work | $0-$300 | $100-$600 | $1,000-$2,000 | Includes meter socket upgrades if needed |
| Labor | $25-$60/hr | $45-$90/hr | $100-$150/hr | Depends on crew size and region |
| Trench restoration | $50-$200 | $200-$600 | $600-$1,200 | Surface repair and reseeding or concrete |
How Distance, Terrain, And Code Requirements Change Quotes
Distance is the dominant driver: longer runs require more conduit, more wiring, and potentially additional trenching. Rugged terrain, clay soil, or rocky ground increase trenching and sometimes bore costs by 20%–60%. Heightened code requirements for outdoor feeders, weatherproof disconnects, and dedicated grounds add small but steady price bumps.
Regional Price Variations In U.S. Markets
Pricing shifts with labor markets and supply chains. In the Northeast and West Coast, expect higher labor and permit fees, whereas the Midwest and Southeast commonly run a touch lower. Estimate a 5% to 20% delta between regions for the same job scope.
Labor Rates And Project Timeline By Region
Journeyman electricians typically bill $75-$125 per hour in many markets; in high-cost areas rates can exceed $150 per hour. A typical project might take 1-3 days for a 40- to 60-foot run, depending on soil and complexity. Plan for weather delays or utility scheduling windows that can shift timelines by a day or two.
Permits, Inspections, And Utility Fees Decoded
Permits usually cover plan review and field inspection; expect a separate utility connection fee if the service is upgraded. Some utilities require a permit or inspection to verify correct grounding and proper meter placement. Budget a modest cushion for permit processing time.
Efficiency Upgrades And Their Impact On Long-Term Costs
Choosing a larger feeder than needed boosts upfront costs but may improve future flexibility and reduce voltage drop. A 60-amp feeder is common for a basic garage workshop, while a 100-amp feeder supports more outlets and potential EV charging. Initial pricing reflects the chosen amperage, with ongoing electricity costs rising modestly if load increases.
Ways To Reduce The Price Without Sacrificing Safety
Options to conserve costs include consolidating work with a single electrical upgrade, selecting standard conduit and off-the-shelf panels, and scheduling work during off-peak seasons. Bundling trenching with other exterior projects can also lower per-project labor charges. Avoid unnecessary upgrades and prioritize the minimum required feeder and outlet count.
Real-World Quote Scenarios And What They Include
Scenario A: 40 ft run, 60-amp service, overhead path, suburban region. Estimated total: $2,800-$4,200, with $1,200-$2,000 allocated to wiring and conduit and $500-$1,500 to labor. Scenario B: 90 ft underground, 100-amp feeder, trenching, and permit fees in a high-cost market. Estimated total: $9,000-$13,500, with trenching $2,000-$4,500 and labor $3,500-$7,500. Both include permit and utility fees, but material costs swing with amperage and installation method.
Per-Unit And Per-Foot Pricing Snapshot
Typical ranges per foot: conduit and wiring $2.50-$6.00, trenching $5-$15, and labor per hour $45-$140. For a midrange 60-amp underground run of 60 ft, a practical estimate is $4,000-$7,000 including permits and service upgrades. Smaller, above-ground runs toward $2,500-$4,000 are common when trenching isn’t required.
What Drives The Final Quote Most
Distance, soil conditions, and amperage are the top quote drivers. A 60-amp feeder with a 40-ft distance may be half the price of a 100-amp underground run at 120 ft. Local permit complexity and utility coordination can add to or subtract from the bottom line. Always verify service capacity with the utility before finalizing scope.
