Why Garage Sub-Panel Cost Varies in Duluth

Detached garage sub-panel cost is driven primarily by trench length. Every linear foot of buried PVC conduit with #4, #6, or #2 copper or aluminum feeders adds up. A garage 30 feet from the house costs roughly half what a garage 80 feet from the house costs. Sub-panel size matters too: a 60-amp sub is enough for lights, outlets, and a small EV charger; a 100-amp sub adds capacity for welders, woodworking shops, or a heated garage; a 200-amp sub feeds an ADU or large shop. NEC 250.32 requires a separate grounding electrode (ground rod) at the detached building, and a 4-wire feeder — we never use the equipment ground as the neutral.

What Drives the Price

  • Trench length from main panel
  • Sub-panel amperage (60A vs 100A vs 200A)
  • Conduit type (PVC vs EMT)
  • Number of circuits served from sub-panel
