Electrical Panel Upgrades in San Diego, CA
San Diego homeowners and landlords are running up against a hard limit: original panels that were never sized for today's loads. Adding an EV charger, a heat pump, or a rooftop solar system to an older bungalow or multi-family building often exposes a 100A or smaller panel that simply cannot carry the demand. Build Bright Home Solutions delivers service upgrades to 200A and above, subpanel installations, and full electrification-ready capacity planning. Our work is backed by 26 years of industry experience in mechanical, electrical, and building-envelope upgrades across Southern California. Whether you are planning a single upgrade or a full home electrification project, we move quickly, pull the right permits, and leave you with a panel sized for where your home is going, not where it has been.

Electrical Panel Upgrades in San Diego
San Diego's older multi-family stock and craftsman bungalow neighborhoods concentrate a large share of homes with undersized electrical infrastructure. Dense lots create rooftop access constraints that make coordinating a solar-plus-panel upgrade more complex than in newer suburban builds. At the same time, the city's year-round mild climate means EV charging and heat-pump water heaters are practical additions at any point in the calendar, so the demand for panel capacity is constant rather than seasonal. Build Bright serves this market with upgrades designed specifically around electrification readiness, including load calculations that account for future EV and HVAC loads, not just current draw. We operate under California Contractor License 1056740, held by Top Tech Builders Inc., and operate under the authority of a team with 26 years of combined industry experience serving the San Diego Metro region.
Panel capacity is usually the first thing to check here. It decides whether a heat pump or an EV charger is a simple job or a service upgrade.
What that involves
- Service upgrades from existing panels to 200A or 400A main service
- Subpanel installation for detached garages, ADUs, and multi-family units
- Load calculations sized for EV chargers, heat pumps, and solar-ready interconnection
- Coordination with the utility on meter and service entrance work
- Panel replacements in older bungalow and multi-family housing with limited clearance

Electrical Panel Upgrades questions from San Diego
- How do I know if my San Diego home needs a panel upgrade?
- Common signs include breakers that trip when you run multiple appliances, a 100A or smaller main breaker, a fuse box rather than a breaker panel, or a contractor telling you the panel cannot support an EV charger or heat pump. A load calculation during your quote appointment will confirm whether an upgrade is needed.
- What size panel does an EV charger or heat pump require?
- Most Level 2 EV chargers draw 40 to 50 amps continuously, and a heat pump system adds additional load on top of existing circuits. Many older San Diego homes with 100A service do not have enough headroom for both. A 200A upgrade is the most common solution, and some homes with multiple units or planned solar additions move to 400A service.
- Will the work require a permit in San Diego?
- Yes. Electrical service upgrades require a permit from the City of San Diego and a final inspection. Build Bright handles the permit application as part of the project so the work is code-compliant and the installation is documented for future buyers or insurers.
- How long does a panel upgrade typically take?
- Most residential service upgrades are completed in one day once the permit is issued and the utility schedules the meter pull. More complex jobs involving subpanels, trench work, or coordination with the utility on new service entrances can take two to three days. We will give you a timeline at the time of your quote.
- Can Build Bright upgrade a panel in a multi-family building or ADU?
- Yes. We work on multi-family buildings, duplexes, and accessory dwelling units throughout San Diego. Each unit's load requirements and the main service feeding the building are reviewed together so the upgrade handles current and planned loads without oversizing the work.
