Panel Upgrades
in Los Angeles.

Residential electrical panel replacements from 100A to 400A. Siemens panels, full AFCI/GFCI build-out, rigid steel conduit mast, LADBS permitted, LADWP coordinated. Every upgrade backed by a written workmanship warranty.

Why LA Homes Need Bigger Panels.

Most homes in Los Angeles built before 1990 have 100 amp panels. That was enough for the 1985 kitchen with a gas range, a window AC, and a single laundry circuit. It is not enough for a 2026 kitchen with an induction range, a heat pump, an EV charger, and a tankless water heater. The result is tripping breakers, dimming lights, and a panel running hot enough that it shows up on your insurance underwriter’s checklist.

If you’re renovating, adding an EV charger, replacing a Federal Pacific or Zinsco panel, or just trying to bring an older home up to the standard the rest of LA is building to, an electrical service upgrade is the work. We do this every week, in every size, across every neighborhood from Calabasas to Pacific Palisades.

What’s Included in an
Alpha One Panel Upgrade.

Every panel upgrade we install is full-scope. You don’t get a partial install with a list of "extras" billed later. Here’s what’s in the quote:

  • Siemens SN or PN-series panel sized to your actual load (100A, 150A, 200A, 320A, or 400A)
  • Full AFCI and GFCI breaker build-out per NEC 2023 — every bedroom, kitchen, bathroom, garage, and outdoor circuit protected
  • Rigid steel conduit mast riser per LADWP spec where required, with proper drip loops and weatherhead
  • New meter base if existing is undersized or aluminum-clad
  • Bonded grounding electrode system — ground rod or UFER as code requires
  • LADBS permit pulled, paid, and posted before work starts
  • LADWP service drop coordination for service shutoff and reconnect at the higher capacity
  • Full breaker labeling with printed labels (no Sharpie) — every circuit named, every device tracked
  • LADBS final inspection attended on-site by us — we don’t hand you a sticker and disappear
  • Written workmanship warranty covering all installation work

Our Panel Upgrade Process.

  1. Free Site VisitYarden walks the property. Looks at the existing panel, the service drop, the meter, and the surrounding access. Photographs the rating plate. Talks through what you’re trying to add (EV charger, kitchen remodel, ADU, pool). Usually same day if you call before noon.
  2. Written EstimateWe send a clear written quote within 24 hours. Scope, panel model, breakers, mast, permit fee, LADWP coordination fee if applicable, total. No verbal handshakes. No "we’ll figure out the rest as we go."
  3. Permit & ScheduleOnce you approve, we pull the LADBS permit and schedule the LADWP shutoff. Permit usually issues within 3-5 business days for residential. LADWP coordination typically lines up within 2 weeks.
  4. Power-Off DayLADWP cuts the service. We pull the old panel, set the new Siemens, run the rigid steel mast riser if needed, install the new meter base, land the bus, set the breakers, run the grounding. Power back on by end of day for most homes.
  5. Trim & LabelDay two if needed: every breaker labeled with printed type, every circuit traced and named, panel cover set true, conduit run square. The work looks the way it works.
  6. LADBS InspectionInspector arrives, we walk them through. First-pass inspection is the standard. If anything fails (it shouldn’t), the rework is on us.
  7. DocumentationYou get the signed inspection card, the permit close-out, the as-built breaker schedule, and a written workmanship warranty. All of it filed in case you sell, refinance, or call us back in five years.

Panel Upgrade Cost & Timeline.

Starting From
$3,400 + permit fees
Most LA residential panel upgrades range $3,400 to $8,500. Final price depends on amperage, mast/meter work, LADWP coordination, and whether existing service conductors need replacement. Every quote is written, itemized, and good for 30 days.

Typical schedule from your first call to a passed inspection: 10 to 21 days — including the permit cycle and the LADWP coordination window. The actual on-site work is one to two days for most residential installs.

Why Siemens.

We install Siemens panels exclusively because they hold up better than the alternatives. The bus is silver-plated copper. The breaker contact pattern doesn’t loosen under heat cycling the way some other brands do. The wiring layout inside the panel is cleaner, which makes inspection passes the first time and makes future service work fast. And the breakers stay available for decades — you can still buy a Siemens QP breaker today that fits a panel from 1995.

You can install a cheaper panel. We don’t. The savings show up in your bid and disappear five years later when something starts arcing.

Quick response and very professional. Explained the scope of work clearly and price is very reasonable. Even the screw lines have been set up perfectly. Looks very nice.

Frequently Asked Questions

Panel Upgrade FAQs.

How much does a panel upgrade cost in Los Angeles?

Panel upgrades in Los Angeles typically range from $3,400 to $8,500 depending on amperage (100A, 150A, 200A, 320A, or 400A), location of the existing panel, condition of the service mast, and whether LADWP service-drop coordination is required.

Every Alpha One Electric panel upgrade is quoted in writing after a free site visit, and includes the panel, breakers, conduit mast where applicable, full LADBS permit, and inspection.

How long does a panel upgrade take?

Most residential panel upgrades take one to two days from power-off to inspection. Day one is the LADWP service shutoff, panel swap, mast and meter base work, and breaker landing. Day two (when needed) is finish work, labeling, and the LADBS final inspection.

Do I need a permit to upgrade my electrical panel in LA?

Yes. Every electrical panel upgrade in the City of Los Angeles requires a permit through LADBS (Los Angeles Department of Building and Safety). Unpermitted panel work can void homeowner insurance and create disclosure issues at sale.

Alpha One Electric pulls every permit and never installs unpermitted panels.

Will my power be off during the upgrade?

Yes — power is off for most of day one while the new panel is set and the LADWP service drop is reconnected. Most homes are powered back on by end of day. We coordinate the shutoff with LADWP in advance and work efficiently to minimize the outage.

What size panel should I install — 100A, 200A, or 400A?

For most modern Los Angeles homes, 200A is the right answer. Older homes with 100A panels often run out of capacity once you add a heat pump, EV charger, or major kitchen remodel.

Larger luxury homes (4,000+ sq ft, multiple HVAC systems, EV chargers, pool, ADU) usually call for 320A or 400A. We size every panel against your actual loads, not a formula.

Why do you only install Siemens panels?

Siemens SN/PN-series panels have the cleanest internal layout, the most reliable bus and breaker contact in the residential category, and parts that remain available decades after install. Other brands work — but we don’t install them. Premium panels for premium homes.

Does my Federal Pacific or Zinsco panel need to be replaced?

Almost always yes. Federal Pacific Stab-Lok and Zinsco panels have well-documented failure patterns where breakers don’t trip under fault conditions, creating a real fire risk. Most home insurance underwriters now require replacement.

If you have one of these, getting a written quote should be your next call.

Do I need to upgrade my panel before installing an EV charger?

Sometimes. A Level 2 EV charger pulls 40-50 amps. If your panel is already 80%+ loaded — common in homes with central A/C, electric range, and electric dryer — adding a charger circuit may push it over capacity.

We always run a load calculation before installing an EV charger. About 40% of LA EV installs we quote include a panel upgrade.

Will I need to upgrade my service drop with LADWP too?

Often, yes. If you’re going from 100A to 200A or higher, LADWP will need to upgrade the service conductors from the pole or transformer to your meter base.

We coordinate that directly with DWP — you don’t need to make any calls. We schedule it, we meet their crew, we handle the inspection.

Is the panel upgrade work warrantied?

Yes. Every Alpha One Electric panel upgrade comes with a written workmanship warranty. If something fails because of how we installed it, we fix it free. The Siemens panel itself carries a separate manufacturer warranty (typically 10 years on breakers, lifetime on the bus).
