Electrical Panel Upgrade for an EV Charger in Mira Mesa?
Many electric vehicle (EV) chargers require a dedicated 40 to 60 amp breaker. If your current electrical panel does not have the capacity or available space, you may need a panel upgrade before installing a charger. This is one of the most common reasons Mira Mesa homeowners call us for panel replacements.
Mira Mesa is home to a large number of tech and biotech professionals who commute to nearby job centers including Qualcomm, MCAS Miramar, Sorrento Valley, and UTC. Electric vehicle adoption among this demographic is strong and growing quickly. If you have recently purchased an EV or are planning to, a Level 2 EV charger requires a dedicated 40 to 60 amp circuit. Most of Mira Mesa's 1970s to 1990s era homes were built long before EV chargers existed, and the original panels in these homes often do not have the spare capacity to support one without an upgrade.
When it comes to EV chargers, our experience shows that a hardwired unit is more reliable and safer than a plug-in model. Hardwiring reduces outlet wear and ensures the charger operates at its full capacity without interruptions.
For homeowners ready to move forward, here is the EV charger we recommend based on reliability and ease of installation:

Do You Need an Electrical Panel Upgrade in Mira Mesa?
Below are a few reasons you might need an electrical panel upgrade or replacement.
Breakers keep tripping
Melted bus bar from a faulty circuit
Burning smell coming from the electrical panel
Electrical panel is physically deteriorating rust, corrosion, or visible damage
More amperage is needed for added loads such as an electric vehicle charger, oven, fireplace, heat pump, or mini-split system
An older Zinsco or Federal Pacific (Stab-Lok) panel that is known to be a fire and safety hazard
A home inspection ahead of a sale or refinance that flagged the electrical panel as a concern
Adding an ADU to your Mira Mesa property very common in this neighborhood given San Diego's expanded ADU allowances
These are a few of the many reasons you might be thinking about upgrading your electrical panel. Below are some photos of electrical panels that were in desperate need of an upgrade.
The electrical panel and wiring in these photos were in really bad shape. CLICK HERE for more information on electrical wiring.
Is There an Advantage to Upgrading Your Electrical Panel in Mira Mesa?
In short, yes.
Many Mira Mesa homeowners put their money into the updates that are easy to see a remodeled kitchen, fresh paint, new flooring, updated bathrooms. Those are all smart investments in a neighborhood where single-family home values have climbed steadily into the $900,000 to $1.1 million range.
One thing that gets overlooked far too often, though, is the backbone of the entire electrical system.
The backbone consists of all the wires and materials you cannot see. The electrical panel is the main component of all of it.
It is not pretty. It is not going to impress your guests or make your home look modern and up to date. But a properly sized, code-compliant electrical panel is what ensures that all the new light fixtures, smart switches, ceiling fans, EV chargers, and other components you install continue to operate safely and without interruption for many years to come.
Here is what makes Mira Mesa particularly relevant right now. The average home in Mira Mesa was built in 1984. Nearly all of the residential housing stock in this neighborhood was developed between 1970 and 1999. That means the vast majority of Mira Mesa homes are now 25 to 50 years old and many of them are still running on the original 100-amp panels they were built with.
Those panels were designed for a very different world. They were never intended to support an EV charger, a modern heat pump system, a home office with heavy power demands, or an ADU. If you are trying to run today's electrical loads through a 40-year-old 100-amp panel, you are pushing that system well beyond what it was built for.
An upgrade gives you the capacity, safety, and long-term reliability your home needs and it protects the value of your investment when it comes time to sell.

What Size Electrical Panel Do You Need in Mira Mesa?
Electrical panels are sized in amps. Which panel you choose will depend on your electrical needs today and your plans for the future.
Below is a breakdown of the most common electrical panel options and why you might choose one over another. This is not a comprehensive list, but it will help give you a clear idea of which panel is right for your Mira Mesa home.
125 Amp Electrical Panel Upgrade or Replacement
You are not adding any electrical load and simply want to replace your existing electrical panel. Your 100 or 125-amp panel is damaged and needs replacement, but no new loads are being added. You have an underground service and do not have the budget for a full 200-amp upgrade at this time
200 Amp Electrical Panel Upgrade or Replacement: The Most Common Upgrade in Mira Mesa
You are not adding any electrical load today, but have plans to in the future. You are looking to add one or two electrical appliances and one electric vehicle charger. You are installing a larger capacity photovoltaic (solar) system. This is the current industry standard for residential properties and the right choice for the vast majority of Mira Mesa single-family homes and townhomes
400 Amp Electrical Panel Upgrade or Replacement
You need a 400-amp replacement for an existing oversized service. You are installing two electric vehicle chargers and have many other high-demand electric appliances in the home. You are looking to fully electrify your home, replacing all gas appliances with electric alternatives. You are building or converting an ADU and need significantly more electrical capacity on the property. You are pairing a large solar array with a whole-home battery storage system
Not sure what size panel is right for your Mira Mesa home?
Most homeowners do not want to run load calculations and you should not have to. CALL: (760) 690-7517 or Text Us anytime, and we will size it correctly for you over the phone. No pressure, no guesswork.
How Much Does an Electrical Panel Upgrade Cost in Mira Mesa, CA?
The cost of upgrading your electrical panel can vary widely depending on your service type and the specific requirements of your installation.
Below are the two most typical cost ranges for properties in Mira Mesa and the greater San Diego area.
Overhead Service (power lines run above your property with a service drop connecting to the weatherhead above your roof) $3,500 to $5,500
Underground Service (no overhead power lines, panel is fed underground from a ground-mounted transformer) $7,000 to $20,000
Underground service upgrades cost significantly more because they require SDG&E coordination, a formal trench inspector pre-meet, conduit excavation, and multiple inspections before the work is complete. While many of Mira Mesa's older single-family homes have overhead service, some properties and newer developments in the area have underground utility feeds.
Additional cost factors include panel amperage (200A vs. 400A), whether stucco or exterior siding repairs are needed after the installation, and permit fees paid to the City of San Diego Development Services Department.
We provide honest, itemized pricing upfront. No hidden fees and no surprises at the end of the job.
A Warning About Unlicensed Electrical Contractors in Mira Mesa
Before we get into the process, this needs to be said.
Many so-called electricians will quote you a much lower price and tell you it is not necessary to wait for SDG&E to process your service change request or to pull a permit through the City of San Diego.
If you run into one of these unprofessional scam artists, send them down the road.
In California, performing an electrical panel upgrade without a permit is illegal. It voids your homeowner's insurance, creates personal liability for you if anything goes wrong, and causes serious complications when you go to sell your home. The City of San Diego requires an electrical permit for all electrical work, including panel upgrades, under San Diego Municipal Code Section 129. A permit can only be issued to a licensed California State Contractor authorized to perform electrical installations.
Any legitimate, licensed electrical contractor knows exactly how to handle the permit process. If someone is telling you a permit is not worth it or is not required, they are cutting corners, and you will be the one left dealing with the consequences.
Always verify your contractor's license before signing anything: CSLB License Lookup
The Mira Mesa Electrical Panel Upgrade Process -- Step by Step
Now that we have covered the key questions, it is time to walk through exactly what to expect from the day you call us to the day your new panel passes final inspection.
One important thing to understand about Mira Mesa: Mira Mesa is a community within the City of San Diego; it is not a separate incorporated city. This means all electrical permits are issued by the City of San Diego Development Services Department (DSD), not a standalone Mira Mesa building department. Permits are submitted online through the City of San Diego DSD portal.
SDG&E is the utility provider for Mira Mesa. All service change requests, trench inspections, and disconnect/reconnect coordination go through SDG&E. We handle all permit applications and SDG&E coordination on your behalf from start to finish.
Below is an outline of the full electrical panel upgrade process. You can click any link to jump to that section.
Request a Service Change From San Diego Gas and Electric (SDG&E)
Waiting Period -- SDG&E Assigns a Planner
Apply For an Electrical Permit Through the City of San Diego Development Services Department
Schedule a Pre-Meet With the SDG&E Trench Inspector (Underground Service Only)
Dig the Trench and Install Conduit (Underground Service Only)
Trench Inspection and Backfill (Underground Service Only)
Schedule the Disconnect/Reconnect With SDG&E
SDG&E Power Disconnection
Install the Grounding and Bonding System
Electrical Panel Removal and Installation
Repair Stucco or Siding
Pass the City of San Diego Final Inspection
Are you ready?
Here we go!
Step 1: Request a Service Change From San Diego Gas and Electric (SDG&E)
To get your Mira Mesa panel upgrade started, you must first submit a service change request to San Diego Gas and Electric (SDG&E) -- the utility provider for Mira Mesa and all of San Diego County.
This request notifies SDG&E that a service change is planned at your property and kicks off their internal review and planning process. Without this step, SDG&E will not be prepared to disconnect and reconnect your service on installation day.
Here are the steps:
Go to SDG&E's work order request form website. Fill out all the necessary information for your installation. Review all the forms and click submit.
This paperwork is included in the cost of your panel upgrade when you hire Landers Electric. We submit it on your behalf and follow up directly with SDG&E so you do not have to manage any of it.
Step 2: Waiting Period -- SDG&E Assigns a Planner
Once the work order has been submitted, the waiting period begins. How long you wait depends on SDG&E's current workload and the complexity of your service configuration.
After the waiting period, your project is assigned to an SDG&E planner. This planner will come out to your Mira Mesa property, assess the installation area, and design the job.
Once complete, the planner will email a detailed report called a work order, with all the requirements for your panel upgrade. This includes:
Panel location, Conduit size, Required clearances, Meter height, Trenching route and depth (for underground service only)
Once the work order is received from SDG&E, it is time to apply for the permit.
Step 3: Apply For an Electrical Permit Through the City of San Diego Development Services Department
After receiving the SDG&E work order, the next step is to pull an electrical permit through the City of San Diego.
A PERMIT IS ALWAYS REQUIRED when upgrading an electrical panel in Mira Mesa.
Many so-called electricians will quote you a lower price and tell you it is not necessary to wait for SDG&E to process your request or to pull a city permit.
If you run into one of those contractors, send them down the road.
All electrical permits in Mira Mesa are issued by the City of San Diego Development Services Department (DSD). Permit applications are submitted online through the City of San Diego DSD portal. All new permit applications must be submitted online. The City of San Diego DSD public counters are open Monday through Thursday from 7 a.m. to 4 p.m. and Friday from 10 a.m. to 4 p.m. for in-person appointments, but for most electrical panel upgrade permits, online submission is the standard process.
We handle the entire permit application on your behalf. You do not need to navigate any of this yourself.
Not sure how permits work in Mira Mesa? CALL: (760) 690-7517 or Text Us anytime. We pull all required permits and handle every piece of paperwork for you.
Step 4: Schedule a Pre-Meet With the SDG&E Trench Inspector (Underground Service Only)
Steps 4, 5, and 6 apply only to underground electrical services.
Before we go any further, it is important to understand the difference between overhead and underground electrical services.
An overhead electrical service is easy to identify. Walk outside and look up. If you see power lines above your home with one set of wires running to the conduit above your electrical panel, you have an overhead service.
An underground electrical service has no overhead power lines. If you look around your property and see green ground-mounted SDG&E transformers on or near the lot, that is a strong sign you have an underground service.
Now back to Step 4.
After receiving the SDG&E work order and pulling the city permit, the next step for an underground service is to schedule a pre-meet with an SDG&E trench inspector. Their job is to ensure the new underground conduit is installed according to SDG&E's standards.
This meeting helps both the homeowner and the electrical contractor understand exactly what is required for the underground portion of the installation, so it is completed the first time correctly.
It is important to call Dig Alert (811) before scheduling this meeting. The work area must be marked with white paint before Dig Alert's arrival. You will not be able to schedule the trench inspector meeting without a Dig Alert reference number. We coordinate all of this for you.
Step 5: Dig the Trench and Install Conduit (Underground Service Only)
Once the SDG&E trench inspector has provided all the necessary directions for the new underground conduit, construction can begin.
The trench is excavated, and approximately 90 percent of the conduit is installed. The final 10 percent of the section that enters into SDG&E's handhole or transformer vault cannot be installed by the electrical contractor. That portion is completed by a utility contractor after the trench is inspected a second time by the trench inspector.
Step 6: Trench Inspection and Backfill (Underground Service Only)
As stated in Step 5, once the conduit has been 90 percent installed, the SDG&E trench inspector must be contacted a second time to approve the installation of the last 10 percent of conduit entering the utility handhole or transformer.
Once that inspection is passed, the SDG&E service coordinator is called to schedule a crew to come out and complete the final conduit installation.
After SDG&E finishes its portion, the electrical contractor is cleared to backfill the trench and repair any driveway, sidewalk, or landscaping that was removed during excavation.
Once all repairs are complete, the trench inspector must be called one last time to approve a final inspection on the underground work. Once that inspection is approved, the panel upgrade can continue to Step 7.
Step 7: Schedule the Disconnect/Reconnect With SDG&E
Steps 4 through 6 were strictly for underground electrical services. Steps 7 through 12 apply to both overhead and underground services.
This step is scheduling what is called a disconnect/reconnect. The disconnect/reconnect is the date SDG&E will de-energize your service so the old panel can be safely removed and the new one installed. This is the main installation day.
The disconnect/reconnect is scheduled through your assigned SDG&E service coordinator. Once the date is confirmed, the City of San Diego Development Services Department is notified so a city inspector can be scheduled to come out to your property on the same day.
Step 8: SDG&E Power Disconnection
Step 8 brings us to the day of the actual electrical panel upgrade.
Early in the morning, an SDG&E crew arrives at your Mira Mesa property to disconnect power at the utility source. This is the only safe way to remove an existing panel, and it is the only way we work.
It is important to remember that approximately three days before the scheduled disconnection date, Dig Alert (811) should be called to re-mark all existing underground utilities in the work area, including gas, water, AT&T, Cox Cable, and others.
Step 9: Install the Grounding and Bonding System
The National Electrical Code requires proper grounding and bonding for all new electrical panel installations.
This includes two ground rods, a cold water pipe bond, and an electrical panel connection.
Some electrical contractors prefer to install the ground rods before the utility power disconnection day because a large pneumatic jackhammer is needed to drive both rods 8 feet into the ground. Planning this step keeps the installation day running efficiently.
Once the ground rods are in place, an unbroken solid copper ground wire sized according to the National Electrical Code must connect both ground rods, the cold water pipe, and the electrical panel.
Proper grounding is required by code and is what protects your home and family in the event of an electrical fault. If you would rather leave this step to a licensed professional, CALL: (760) 690-7517 or Text Us anytime and we will get right back to you.
Step 10: Electrical Panel Removal and Installation
THIS STEP CAN ONLY BE COMPLETED ONCE SDG&E HAS DISCONNECTED THE POWER AT THE UTILITY SOURCE.
Once the power has been disconnected at its origination point, the old panel is carefully removed, and the new panel is installed.
If you have an overhead electrical service, a new riser and weatherhead will be installed at least 24 inches above the roofline for utility connection.
After the installation, a City of San Diego Development Services Department inspector visits the site to verify that the installation is in compliance with the National Electrical Code. If the inspection is passed, the city inspector notifies SDG&E, and power is restored to your home the same day.
Step 11: Repair Stucco or Siding
Removing an electrical panel requires cutting into the exterior stucco or siding of the home.
Once the panel is installed and the inspection is on the calendar, the affected area is patched, waterproofed, and textured to match the surrounding exterior as closely as possible. Most Mira Mesa homes have stucco exteriors, so this is a routine part of every panel upgrade we complete in the area.
Repairs must be completed and the affected area must be painted before a final inspection can be passed.
We handle this repair as part of the job so your home is left clean and weather-tight.
Step 12: Pass the City of San Diego Final Inspection
The final inspection is the last milestone in the electrical panel upgrade process.
A City of San Diego Development Services Department inspector reviews the entire completed installation the panel, grounding system, conductor labeling, stucco repair, and waterproofing to verify compliance with the NEC, CEC, and all applicable City of San Diego requirements.
Remember that stucco or siding repairs and waterproofing must be completed, and the affected area must be painted before the final inspection can be passed.
Once the final inspection is approved, the electrical panel upgrade is complete, and your power is permanently restored under your new electrical service.
When you hire Landers Electric, we stay on the job until the city inspection is passed and your power is safely restored. CALL: (760) 690-7517 or Text Us anytime and we will get right back to you.
Frequently Asked Questions About Electrical Panel Upgrades in Mira Mesa, CA
What are the signs that I need an electrical panel upgrade?
Common signs include flickering lights, frequently tripping breakers, a burning smell coming from the panel, or a panel that is physically deteriorating. If you are planning to add an EV charger, a new HVAC system, an ADU, or any other high-demand appliance or load, those are also strong reasons to evaluate your current panel capacity. If your home was built in the 1970s, 1980s, or 1990s and still has the original panel, it is worth having it assessed.
What is the average cost of an electrical panel upgrade in Mira Mesa?
In the San Diego area, a standard overhead service panel upgrade typically costs between $3,500 and $5,500. An underground service upgrade is more extensive and typically ranges from $7,000 to $20,000, depending on the scope, panel amperage, and site conditions. Contact us for a specific quote for your Mira Mesa property.
Who issues electrical permits in Mira Mesa?
Mira Mesa is a community within the City of San Diego, not a separate incorporated city. All electrical permits are issued by the City of San Diego Development Services Department (DSD). Permits are submitted online through the City of San Diego DSD portal. Landers Electric handles all permit applications on your behalf from start to finish.
How long does an electrical panel upgrade take in Mira Mesa?
The physical installation is typically completed in a single day. The full process, including the SDG&E work order, waiting period, city permit, and all required inspections, can take several weeks from start to finish, depending on SDG&E's current processing times and whether your service is overhead or underground.
Is a 100-amp panel enough for my Mira Mesa home?
For most modern homes in Mira Mesa, a 100-amp panel is no longer sufficient. A 200-amp panel is now the industry standard and handles modern appliances, air conditioning, and EV chargers without issue. Given that most Mira Mesa homes were built between 1970 and 1999, many properties are still running on original 100-amp services that were never designed for today's electrical demands.
Can I do a panel upgrade myself?
No. An electrical panel upgrade is extremely technical and dangerous work involving high-voltage power. Under San Diego Municipal Code Section 129, electrical permits can only be issued to a licensed California State Contractor. Attempting this work without a license means no permit, no inspection, and no legal or insurance protection for you as the homeowner.
What is the most common reason for a failed inspection in Mira Mesa?
Failed inspections are most often caused by improper wiring, incorrect grounding, or work that does not follow the current National Electrical Code. Using a licensed and experienced electrical contractor significantly reduces the risk of a failed inspection.
Who do I contact for an electrical panel upgrade in Mira Mesa?
Contact Landers Electric at (760) 690-7517 or visit landerselectric.net. We will assess your situation, give you an honest quote, and handle the entire process from the first SDG&E work order to the final city inspection.
