Electrical Panel Upgrades for Miramar Homes and Businesses
Miramar is one of San Diego's most active and diverse neighborhoods. Stretching along the Miramar Road corridor between Interstate 15 and Interstate 805, the area encompasses a significant mix of residential communities, light industrial parks, commercial properties, and the Marine Corps Air Station Miramar. That variety creates a broad range of electrical panel needs, from residential upgrades in neighborhoods like Mira Mesa and Scripps Ranch to commercial service changes in the industrial and warehouse districts along Miramar Road and Camino Santa Fe.
Most of the residential housing in the Miramar area was built between the 1970s and the 1990s. Homes from this era were wired for electrical demands that look nothing like the loads a modern household places on a panel today. Central air conditioning, multiple EV chargers, home offices, and whole-home battery storage systems were not part of the calculation when many of these panels were installed, and the gap between what those systems were designed to handle and what homeowners are asking of them continues to grow.
Landers Electric has the experience and licensing to serve both sides of Miramar. Whether you are a homeowner in a 1980s build on the residential side of the neighborhood or a business owner managing an industrial or commercial property along Miramar Road, we handle the full scope of your panel upgrade from initial assessment through final inspection.

Why Miramar Property Owners Are Upgrading Their Electrical Panels
Panel upgrade demand in Miramar is being driven by a consistent set of factors, both in the residential neighborhoods and in the commercial and industrial corridors.
Aging residential panels from the 1970s and 1980s. A large portion of the housing stock in the Miramar area was built during the period when 100-amp panels were standard. These systems are now 40 to 50 years old, and many have never been upgraded. Whether the panel itself has deteriorated or simply lacks the capacity for a modern household, the case for replacement is clear.
Commercial and industrial tenant improvements. The Miramar industrial corridor along Miramar Road, Camino Santa Fe, and Activity Road supports a wide range of businesses, from light manufacturing and distribution to tech and service operations. Tenant improvements, equipment upgrades, and build-outs in this district regularly require electrical service upgrades to support higher power demands and additional circuits.
EV charger installations. Miramar residents are adopting electric vehicles at a strong pace. A Level 2 home charger requires a dedicated 240-volt, 40 to 60-amp circuit. For homes with older or lower-capacity panels, the EV charger installation cannot happen until the panel is upgraded to accommodate the additional load.
Solar and battery storage systems. San Diego's energy costs and abundant sunshine have made residential solar common throughout Miramar and neighboring communities. When a homeowner adds solar panels, a battery backup system, or a whole-home generator, the existing panel often needs to be evaluated and in many cases upgraded before the installation can proceed.
Zinsco and Federal Pacific panels. Both of these panel brands appear in Miramar homes from the 1970s and 1980s, and both carry well-documented safety risks. Zinsco breakers are prone to fusing in the closed position, meaning they may fail to trip during an overload or short circuit. Federal Pacific panels have a similar history of breaker failure. If your home has either of these brands, replacement is strongly recommended regardless of whether you are adding any new electrical load.

Warning Signs That Your Miramar Property Needs a Panel Upgrade
Electrical panels do not always fail dramatically. Often the signs develop gradually and are easy to explain away until they become a safety issue. Here is what to watch for.
Breakers that trip on a regular basis. If you are resetting the same breaker repeatedly, it is not the breaker being overly sensitive. It is the panel telling you that the circuit cannot support the load being placed on it.
Lights that dim or flicker when appliances start. Noticeable voltage drops when the air conditioner, well pump, or refrigerator cycles on point to inadequate service capacity. A properly sized panel should handle multiple simultaneous loads without any visible effect on other circuits.
A warm panel door or a burning smell near the electrical box. Any heat or burning odor associated with your panel requires immediate attention from a licensed electrician. These are not minor issues and should not be monitored over time.
Visible corrosion, rust, or discoloration inside the panel. Scorch marks around breaker terminals or visible corrosion on panel components indicate past overheating events or moisture infiltration, both of which compromise the integrity of the system.
No available breaker space for new circuits. A full panel is a problem. Doubling up circuits with tandem breakers to create space is not a long-term solution and can create safety and code compliance issues.
Your home inspector or insurance provider flagged the panel. A report or notice from an inspector or insurer about your electrical panel is not something to defer indefinitely. It represents an identified risk that puts your property and your coverage at stake.
What Panel Size Does Your Miramar Property Need?
Selecting the right panel size comes down to what you are currently running on the property and what you plan to add. Here is a straightforward breakdown of the most common options.
100-Amp Panel A 100-amp panel may be adequate for a small detached structure with minimal load, but it is insufficient for the primary electrical service of any modern home. If your home still has a 100-amp panel, it should be evaluated for replacement, particularly if you are planning to add any significant load.
200-Amp Panel The 200-amp service panel is the current standard for residential properties throughout San Diego and the right choice for the majority of Miramar homeowners. It supports central HVAC, a full set of kitchen and laundry appliances, home office equipment, outdoor lighting, and a single Level 2 EV charger, with room for future additions. Most residential upgrade projects in Miramar result in a 200-amp installation.
400-Amp Panel or Dual-Meter Configuration For larger homes, properties with significant electrical demands, or commercial and light industrial applications, a 400-amp service or a dual-meter setup may be the appropriate solution. This configuration is also relevant for homeowners who plan to fully electrify, adding a heat pump system, multiple EV chargers, and battery storage at the same time.
If you are not sure which size applies to your property, a quick conversation about your current setup and plans will usually provide a clear answer. 📞 Call us at (760) 690-7517 and we will size it for you at no charge.

How Much Does a Panel Upgrade Cost in Miramar?
Panel upgrade costs in Miramar vary depending on the type of service feeding the property and the specific requirements of the installation. The two primary configurations are overhead service and underground service.
Overhead Service An overhead service is fed by lines running above the property to a service drop attached to the building. This is the more straightforward configuration to upgrade. Typical cost range: $3,500 to $6,000 for a standard 200-amp upgrade.
Underground Service An underground service is fed through buried conduit, often from a pad-mounted transformer on or near the property. Underground upgrades involve more coordination, including SDG&E planner visits, conduit installation, and trench inspections, and they cost more as a result. Typical cost range: $7,000 to $20,000 or more, depending on trench length, site conditions, and whether any utility infrastructure needs to be relocated.
Additional factors that affect the total cost include:
Whether the panel location or meter height is changing
Grounding system updates needed to meet current NEC code requirements
Repairs to stucco, siding, or exterior finishes after installation
City of San Diego permit fees
Whether a subpanel is being added to serve a detached structure or additional circuits

The Panel Upgrade Process in Miramar, San Diego
Upgrading an electrical panel in Miramar requires coordination between Landers Electric, the City of San Diego Building Department, and SDG&E. Here is exactly what the process looks like from start to finish.
Step 1: Site Assessment and Written Quote
The project begins with an assessment of your current electrical system, including the panel, service entrance, and service type. We evaluate your existing load and any planned additions, then provide a written quote that covers every aspect of the work before anything is scheduled.
Step 2: SDG&E Work Order
Before installation can begin, a work order must be submitted to SDG&E authorizing the service change. For overhead service upgrades, this is largely an administrative process. For underground service projects, it initiates a planner visit in which an SDG&E representative comes to the property and produces a written work order specifying the conduit path, trench requirements, and any utility-side infrastructure work that may be needed. Landers Electric submits all paperwork and manages all follow-up with SDG&E on your behalf.
Step 3: City of San Diego Permit
All electrical panel installations in the City of San Diego require a building permit. Skipping the permit process is not an option that any responsible contractor should offer, and it is not something Landers Electric does. A permitted installation is inspected by the city and confirmed to meet current code, which protects the property owner against liability, ensures insurance coverage is not compromised, and simplifies any future sale of the property. We handle the permit application and all inspection scheduling.
Step 4: Underground Work (Where Applicable)
For underground-fed properties, additional steps are required before the panel installation can proceed. We coordinate with SDG&E's trench inspection team to confirm the conduit route and installation requirements, then perform the excavation and conduit installation according to those specifications. The trench inspection process involves multiple SDG&E site visits, and the utility's own crew handles the conduit section connecting to their equipment. Once the underground work is approved, the trench is backfilled and any affected surfaces are restored.
Step 5: Panel Removal and Installation
On installation day, SDG&E de-energizes the service. The old panel is removed and the new panel is installed, including a new grounding and bonding system per current NEC requirements. For overhead service properties, a new weatherhead and riser are installed as part of this step. Following installation, the city inspector reviews the work for code compliance. Once approved, SDG&E restores power.
Step 6: Final Walk-Through and Circuit Labeling
Before we leave the job, every circuit in the new panel is labeled and tested. We walk you through the completed installation, confirm everything is functioning correctly, and answer any questions about your new system. The project is not considered complete until the city inspection is passed and the installation is verified.
✅ Landers Electric manages every step from permit to final inspection. You do not need to coordinate with the city or the utility company. We handle all of it.
Panel Upgrades for Commercial and Industrial Properties in Miramar
The Miramar industrial and commercial corridor has a distinct set of electrical needs compared to residential properties, and Landers Electric is equipped to handle them. Businesses along Miramar Road, Camino Santa Fe, Activity Road, and the surrounding industrial parks regularly require service upgrades as part of tenant improvements, equipment additions, or build-outs.
Common commercial panel upgrade scenarios in the Miramar area include:
Tenant improvement projects that require additional circuits, higher amperage service, or a reconfigured panel to support new equipment or a different layout within an existing industrial or commercial space.
Service upgrades for manufacturing and warehouse operations where equipment additions exceed the capacity of the existing electrical service.
New business occupancies moving into older buildings where the existing panel does not meet current code or does not have adequate capacity for the intended use.
Three-phase service installations for businesses that operate equipment requiring three-phase power, which is common in light industrial and manufacturing environments.
Landers Electric works directly with business owners, property managers, and general contractors on commercial panel projects throughout the Miramar corridor. 📞 Contact us at (760) 690-7517 to discuss your commercial project.
EV Charger Installation and Panel Upgrades in Miramar
One of the most common reasons Miramar homeowners call Landers Electric is that they have purchased an electric vehicle and discovered that their existing panel cannot support a Level 2 charger. A Level 2 EV charger requires a dedicated 240-volt circuit with a 40 to 60-amp breaker, and older panels in the Miramar area frequently do not have the available capacity or breaker space to accommodate it without a panel upgrade first.
In many cases, we can combine the panel upgrade and the EV charger installation into a single project, completing both under one permit and one inspection. This approach saves time, reduces overall cost, and eliminates the need to schedule and coordinate two separate jobs.

Frequently Asked Questions: Panel Upgrades in Miramar, San Diego
Who issues the permit for a panel upgrade in Miramar? Miramar falls within the City of San Diego, so all electrical panel permits are issued by the City of San Diego Development Services Department. Landers Electric pulls all required permits and schedules all inspections as part of every panel upgrade project.
How long does a panel upgrade take from start to finish in Miramar? The physical installation is typically completed in one day. The full process, including the SDG&E work order, permit approval, and city inspection, generally takes four to eight weeks from the initial quote to final sign-off. Underground service projects may take longer due to the additional inspection steps involved. We keep you updated throughout.
My home was built in the early 1980s. Should I have my panel inspected? Yes. Homes in Miramar built during the 1970s and 1980s are more likely to have panels that are undersized for current demands, outdated in design, or from brands with known safety issues such as Zinsco or Federal Pacific. Even if you are not experiencing obvious problems, a panel assessment is a worthwhile step for a home of that age.
Can you upgrade the panel for my commercial space in the Miramar industrial corridor? Yes. Landers Electric handles commercial panel upgrades and service changes throughout the Miramar area, including properties in the industrial parks along Miramar Road, Camino Santa Fe, and Activity Road. We work directly with property managers, tenants, and general contractors on commercial projects.
Do I need to notify my tenant or prepare for a power outage during the upgrade? Yes. Your property will be without power for several hours on installation day while the old panel is removed and the new one is installed. We give you a clear timeline in advance so you can make any necessary preparations.
Can I combine a subpanel installation with the main panel upgrade? Yes, and in most cases it makes sense to do so. If you want to add a subpanel to a garage, an ADU, or another structure on the property, combining that work with the main panel upgrade is more cost-effective than scheduling it as a separate job later.
Are you licensed and insured to work in the City of San Diego? Yes. Landers Electric holds California C-10 Electrical Contractor License Number 1089091, verifiable through the Contractors State License Board. We carry full general liability insurance and are fully authorized to pull permits and perform electrical work throughout the City of San Diego, including the Miramar area.
