Sub Panel Installation in San Mateo, CA
Whether you are converting a garage, building an accessory dwelling unit, or finally wiring the shop behind the house, a sub panel is the clean way to do it. Our electricians design and install sub panels for San Mateo homeowners and small businesses throughout San Mateo County.
Sub Panel Installation services we provide in San Mateo
- Garage and detached workshop sub panels
- ADU and guest house electrical panels

Each sub panel project in San Mateo starts with a load calculation to confirm the main service can support the new panel. We then run a properly sized feeder, install the sub panel with its own breakers, bond and ground it correctly, and label everything. The result is a clean, expandable panel that passes inspection the first time.
We have installed sub panels for garages, ADUs and shops in San Mateo and neighboring Burlingame, Belmont and San Francisco. If your main panel is already full, we can also discuss whether a panel upgrade should be paired with the sub panel so you are not back at capacity next year.
A sub panel makes sense in San Mateo when
- You are building or converting an ADU or garage
- The main panel has no open breaker spaces
- You need several new circuits in one area
- You are adding a shop with 240-volt tools
- Pool or spa equipment needs its own feed
