Electrical Panel Installation for New Circuits, Subpanels and ADUs
Red Electricians installs new and additional electrical panels for homeowners and builders, including subpanels for garages, workshops and accessory dwelling units. Electrical panel installation starts from $600, with a free estimate (starting price; your cost may differ).
Electrical panel installation means something is being added: a new panel, a subpanel out in the garage, a board for a backyard unit. If you are after a bigger replacement for the panel you already have, that is a different job. See all of the electrical services we offer to find the right page, or call and tell us what you have.

Overview
New panel, subpanel or breaker box: when electrical panel installation makes sense
People tend to say “breaker box” or “electrical box” when they call us, and they often say “change out” where we say “install”. Whatever the word, the first thing we want to know is whether a new panel is being added or the old one is being swapped. Installation fits when:
- A garage, workshop, shed or accessory dwelling unit needs its own distribution board.
- A new building, addition or service is being wired and has nothing to connect to yet.
- An existing panel has to move, or a second panel is needed because there is no room left for more circuits.
If you want an existing panel replaced, read about replacing an existing panel instead.
What we do
What a panel installation job can include
Every price in this section: starting price; your cost may differ.
Subpanel for a garage, workshop or shed
A feeder from the main panel to a new board, with branch circuits laid out for the tools and lights that will actually be used. Starts from $600 with a free estimate.
Panel for an ADU or detached structure
A distribution board for a backyard or garage unit, placed so the cabinet keeps its working clearance. Read our ADU electrical panel requirements guide before you call.
New-construction and added-service panels
A panel for a new build or addition, set up with the circuits the layout calls for and room to add more later.
Panel relocation and added circuits
Moving a board to a better spot, or adding dedicated circuits where the existing board has no space left.
Commercial, multi-unit and rented properties
Panels for shops, small commercial spaces and rented buildings, where we also need to know who gives us access. See our commercial electrical services.
If something is hot, burnt or has lost power, it is not a planning question. Call us and read about our emergency electrician service.
Pricing
Electrical panel installation cost: starting at $600 and what changes the price
How much does it cost to install an electrical panel? Installation starts from $600 and comes with a free estimate. The price depends on the job itself, so a visit comes before a firm figure.
We can rarely give an honest panel price without seeing the layout. A feeder that runs 20 feet and one that runs 120 feet are very different jobs. That is why the free estimate comes first.
Every price in this section: starting price; your cost may differ.
| Service | Starting price | What changes the final price | Estimate |
|---|---|---|---|
| Electrical panel installation | From $600 | Feeder distance, grounding work, panel rating, number of circuits, relocation, and permit and inspection timing | Free estimate |
| Panel repair (existing panel stays) | From $99 | Which part is faulty | Quoted on the call |
| Circuit breaker repair | From $79 | The breaker and the circuit it protects | Not free; free estimate applies to breaker replacement only |
Decision guide
New panel, subpanel or replacement panel: which job do you have?
| New or added panel (this page) | Subpanel | Replacing an existing panel | Repairing a panel part | |
|---|---|---|---|---|
| Typical trigger | New building, new service or no room left | Garage, workshop or ADU needs its own board | Old board is worn, unsafe or too small | One part of the panel has failed |
| What is installed | A new panel and its circuits | A board fed from the main panel | A new panel in place of the old one | A repaired or swapped part |
| Estimate | Free | Free | Free | Not free; quoted on the call |
| Page to read | This page | This page | Replacing an existing panel | Panel repair |
Not sure whether the problem is the panel, the breaker or the whole service? That is a common mix-up. A single tripping breaker is a breaker repair question. Tell us what you see and we will point you to the right job.
The visit
From the free estimate visit to inspection: how a panel installation runs
- Call us, or send the form. A form request gets a callback in about 5 minutes.
- Tell us what the panel is for and where it would go. Photos of the space and the existing panel help.
- We find a time that suits you. Same-day service is possible in many cases, and if not, it is usually the next day or within a few days.
- The electrician looks at the site and the layout and reviews the loads the new panel must carry. The estimate is free.
- You approve the plan, and the new panel is installed and every circuit is tested and labeled.
- Where the city requires a permit, the work is arranged around it, and inspections happen before the equipment is used.
Can you send a photo or video instead of a visit? A photo helps us plan, but a technician still needs to see the site before we confirm the work.
Field notes
Field notes: workshop, utility-room and ADU panels
A new detached workshop had no distribution of its own, and the owner wanted separate circuits for tools, extraction and lighting. The load plan called for a feeder and eight branch positions with spare capacity. We installed a feeder-supplied panelboard with the required separation and grounding, and checked the feeder, grounding, protection and every workshop load before handover. The panel was placed so the working area beside the tool storage stayed clear. The relevant reference is NFPA 70 (NEC), 215, 250 and 408.
A new distribution board starts with its loads and access requirements, not an empty wall position.
Our electrician
Our electrician’s advice: provide the workshop equipment list before deciding the circuit layout. Planning spare positions at the start meant the board was not sized only for the first week of use.
A utility-room panel downstream of the service
A new utility-room panel sat downstream of the existing service enclosure, so how the two were bonded mattered. We reviewed the feeder route and the equipment instructions first, and the homeowner learned why a second neutral-to-ground connection could not simply be copied from the service layout. A new enclosure gave a clearly labeled extra distribution point. It did not, by itself, add capacity to the original service.
An ADU board that would have blocked access
The first plan for an accessory dwelling put the cabinet in a compact service space where working access would have been blocked. Because the framing was still open, we moved the board before the walls closed and agreed the inspection order with the designer. The lesson is that layout is worth settling early.

Customer feedback
What customers say about panel work
We have no customer review about a brand-new panel installation that we have not already shown elsewhere, and we will not repeat one. Our Pasadena profile on Google is rated 5.0 from 71 reviews (checked Oct 8, 2026), and many of those reviews talk about panel work and careful labeling. That rating belongs to the Pasadena profile only. Read what our customers say.
Common questions
Questions about installing a panel: free visit, price, permits and timing
Can someone come and estimate a new panel, and is the visit free?
Yes. The estimate for panel installation is free. Call us or send the form and we set a time.
How much does it cost, and can you give me a ballpark?
Installation starts from $600. It is a starting price, and your cost may differ. The feeder length, the panel rating, how many circuits you need and the grounding work all move the number, so we give you a firm figure after the free estimate.
How soon can you come?
Same day in many cases. Otherwise the next day or within a few days. We do not promise a time before we hear about the job.
Do I need a permit, and who handles it?
Permits and inspections are done as the city requires. We will tell you what applies to your job when we plan it.
Can you add a subpanel for a garage, workshop or ADU?
Yes. Send us the equipment list and a photo of the space. See the field notes above for how we planned a workshop board.
Do you do commercial or multi-unit buildings?
Yes. Tell us about the property and who can give us access. See our commercial electrical services.
My insurer or inspector will not accept my panel. What now?
That usually means the old panel has to be replaced, which is a different job from installing a new one. Read about replacing an existing panel.
Does my new panel add capacity to the whole house?
Not by itself. A new board gives you more circuits. It does not make the incoming supply bigger. We explain what your service can carry when we plan the job.
Do you offer a warranty?
Red Electricians offers a standard warranty on its work. Ask your technician for the details when you call.
