Subpanel Installation
Power your garage, ADU, or workshop without a full panel upgrade.
You’re in good hands. Our team will follow up promptly.
A subpanel extends power to a specific part of your property — a detached garage, an ADU, a workshop, a pool equipment area — without requiring you to run every new circuit back through the main panel individually. It’s fed from the main panel through a dedicated power line, then distributes power locally from there.
When a Subpanel Makes More Sense Than a Main Panel Upgrade
If your main panel already has enough spare capacity to feed a subpanel, adding one is often faster and less disruptive than a full main-panel upgrade. We evaluate your existing service capacity first; if it can’t support both the home and the new subpanel’s demand, a Panel Upgrade may need to happen first or alongside it.
Common Subpanel Projects
- Converting a detached garage into a workshop or living space that needs multiple circuits.
- Powering an ADU or guest unit with its own dedicated load center.
- Running power to a pool, spa, or outdoor kitchen area.
- Adding capacity for a home office or studio in a separate structure.
Subpanel Installation Cost
Subpanel installation starts from $1,000 per our current pricing guide, with the final cost depending on the distance from the main panel, whether digging a trench or running protective wire tubing is needed to reach a detached structure, and the subpanel’s size. Permits, when required, start from $150 separately.

Frequently Asked Questions
Do I need a subpanel or a full main panel upgrade?
If your main panel has spare capacity, a subpanel is usually the simpler and less expensive path to powering a detached structure. If it doesn’t, an upgrade may be needed first. We check your actual capacity before recommending either.
How much does a subpanel installation cost?
Subpanel installation starts from $1,000 per our current pricing guide, with distance to the structure and any digging or conduit work affecting the final price.
Can a subpanel power an entire ADU?
Often, yes, depending on the ADU’s size and appliance load. We size the subpanel to the actual planned use rather than a generic default.
Is a permit required for a subpanel?
Yes, in every jurisdiction we serve. We handle the permit application and inspection scheduling.
