National Baseline & Scope Drivers
Adding a subpanel to feed a garage, basement, workshop, or addition when the main panel is full or distant. National planning range for this job sits between $900 and $3,500.
Key Price Drivers for Subpanel Installation
- Subpanel size and feeder: A 60-amp subpanel needs 6 AWG copper feeder. A 100-amp subpanel needs 2 AWG copper or 1/0 aluminum. The feeder run length drives voltage drop and conductor cost.
- Distance from main panel: A subpanel in the garage on the other side of the same wall is cheapest. A detached garage 100 feet away needs a buried feeder in conduit at significant cost per foot.
- Main panel capacity: The subpanel load counts against the main service. A 200A service can support a 100A subpanel if the calculated load allows. A 100A service may not have room for a large sub.
- Number of circuits needed: A 6-space subpanel covers a small garage. A finished basement workshop may need a 20-space panel. Larger panels cost more but avoid a second subpanel later.
- Detached structure bonding: A subpanel in a detached garage requires its own grounding electrode (ground rod) and a 4-wire feeder. Bonding mistakes here are a common inspection failure.
