Homeowners typically see a range for installing a sub panel in a garage from roughly $1,200 to $4,500, depending on amperage, distance from the main panel, and wiring requirements. The price is driven by panel size, conductor type, labor, and any required permits.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Sub panel & breakers | $120 | $350 | $700 | Includes main breakers and enclosure |
| Materials (wires, conduit) | $100 | $400 | $1,200 | Depends on amperage and distance |
| Labor | $500 | $1,500 | $2,500 | Electrician hourly rates plus crew time |
| Permits & inspections | $50 | $350 | $600 | Local code requirements |
| Permits, code upgrades | $0 | $250 | $1,000 | Possible panel and grounding updates |
| Delivery / disposal | $20 | $80 | $200 | Trash disposal of old panel if applicable |
| Misc. / contingency | $50 | $250 | $600 | Overruns, material mistakes |
Assumptions: region, specs, labor hours.
Overview Of Costs
Project range and per-unit estimates: A typical garage sub panel install spans 60A to 100A. For 60A, total project price often falls in the $1,200-$2,500 range. For 100A, expect $2,000-$4,500, depending on distance from the main panel and required upgrades. Per‑unit benchmarks include about $20-$40 per linear foot of feeder wire, and $100-$150 per circuit added.
Assumptions and conditions: The main panel is accessible, the garage has adequate clearance, and no major code upgrades are needed. If a service upgrade or grounding electrode system is required, costs rise accordingly.
Cost Breakdown
The following table presents typical cost components and ranges. The figures assume residential electrical work in a mid-sized U.S. city and include labor, materials, and standard permits.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $120 | $400 | $1,200 | Panel, breakers, feeders |
| Labor | $500 | $1,500 | $2,500 | Electrical contractor rate |
| Permits | $50 | $350 | $600 | Local permit and inspection fees |
| Delivery / disposal | $20 | $80 | $200 | Materials transport and old gear removal |
| Contingency | $50 | $250 | $600 | Unforeseen work |
| Taxes | $5 | $100 | $200 | State/local taxes |
What Drives Price
Key variables include amperage (60A vs 100A), feeder distance, and wire gauge. Shorter runs with 4 AWG copper or 2/0 aluminum feeders cost less than long runs requiring heavier conductors. Another driver is the type of enclosure and whether a new grounding electrode system is needed, which can add $200-$800 in extra materials and labor. The presence of protected routing (through finished spaces) also increases labor time and cost.
Additional factors include existing panel space and accessibility. If the main panel is in a cramped area or requires dismantling cabinetry, expect higher labor charges. If a full indoor to outdoor transition is necessary for the feeder, budget increases accordingly.
Regional Price Differences
Prices vary by region due to labor markets and permit requirements. In the Northeast, expect higher labor and permit fees, while the Midwest can be more cost-competitive. The West Coast often shows elevated material costs due to shipping and availability. For a three-region comparison, 60A installs may range roughly as follows: Northeast $1,700-$3,100, Midwest $1,400-$2,600, West $1,900-$3,200. These deltas illustrate typical regional spread.
Labor & Installation Time
Typical installation time is 1–2 days for a straightforward 60A run, but more complex 100A installations with long feeders or code upgrades can take 2–3 days. Labor cost commonly accounts for 60–70% of the project total. A longer run or difficult routing raises both time and cost. data-formula=”labor_hours × hourly_rate”>
Additional & Hidden Costs
Surprises can include upgrading the main service panel if there is insufficient main disconnect or limited spare spaces. Grounding electrode system upgrades may be required by code in some municipalities. If a permit is required for the work, expect additional inspection fees. Materials like conduit, connectors, and protective plates add up, especially for longer runs or exposed installations.
Real-World Pricing Examples
Three scenario cards illustrate practical expectations. Each scenario includes specs, labor hours, per-unit pricing, and totals. Assumptions: single-family garage, standard 120/240V service, no major code upgrades beyond standard sub panel install.
