If you love your Eichler, you probably love it for the same reasons I do: clean lines, indoor-outdoor living, and a design that still feels intentional decades later.
The one thing that rarely ages as gracefully is the electrical system, especially if you are adding an EV, remodeling a kitchen, or switching appliances from gas to electric.
The good news is that a smart upgrade plan can protect the architecture while giving you the capacity and safety features a modern home needs.
If you want a helpful overview of how utility coordination can work for panel upgrades, PG&E publishes a homeowner-friendly guide you can skim before you start calling contractors, like this electrical panel upgrade roadmap.
If you are comparing charging options, the U.S. DOT EV charging basics page is a simple reference on what Level 2 charging actually means in practice.
In this guide, I will walk you through why Eichler electrical systems often need upgrades, how to spot overload risks, what size service many homeowners move toward, and how to plan an EV charger without turning your remodel into a patchwork of compromises.
Why Eichler Electrical Systems Often Need Upgrades
Eichlers were built for a different era of electrical demand. Back then, homes typically had fewer large appliances running at once, and they definitely were not supporting EV charging, induction cooking, heat pumps, or a home office setup in every room. Many Eichlers still have older panels, limited circuit capacity, and wiring pathways that were never meant for frequent retrofits.
Here is what tends to push an Eichler over the edge today:
- More simultaneous load: EV charging plus cooking plus HVAC can stack quickly.
- Older service sizes: Many homes started with smaller service and fewer breaker spaces.
- Safety gaps: Missing grounding, outdated breakers, and older receptacles can raise risk.
- Architecture-driven constraints: Open beam ceilings and slab construction make routing new wiring harder than in a conventional attic home.
Before you pick an EV charger or start a remodel, ask for an electrical assessment that includes (1) panel condition, (2) service size, (3) available breaker space, and (4) a plan for routing new circuits that respects the home’s design.
Signs Your Eichler May Be Overloaded
Some warning signs are subtle, and others are “stop and call someone today” urgent. If you are experiencing any of the items below, treat them as a prompt to get a licensed electrician involved.
Common overload or failing connection signs include:
- Lights flickering or dimming when a major appliance turns on
- Breakers tripping repeatedly, especially when nothing “new” has changed
- Warm outlets or switch plates (they should not feel hot)
- Buzzing or crackling near the panel or a receptacle
- Burning smell or discoloration around outlets, switches, or breakers
- Outdated breakers that do not reset cleanly or feel loose
- Insufficient amperage for planned upgrades, like EV charging or a kitchen remodel
If you notice a burning smell, visible scorching, or persistent buzzing, shut off the affected circuit and get professional help immediately. Those are not “wait and see” issues.
How Much Electrical Service Do You Need for Modern Loads
For many Eichler owners, the service size question comes up fast: do you stay at 100 amps, or move to 200 amps? The right answer depends on your actual loads, not a rule of thumb, and a proper load calculation is the clean way to decide.
A practical way to think about it:
- 100 amp service can be workable if you have modest electrical appliances, no EV charging, and no major electrification plans.
- 200 amp service is commonly pursued when you add a Level 2 EV charger, electrify major appliances, add HVAC equipment, or expand living space.
- Load management systems can sometimes help if you want EV charging without a full service upgrade right away, but they still require careful design.
A simple planning checklist you can use before the electrician visit
- List every major appliance you have now and what you want to add (EV charger, induction range, heat pump, dryer, hot tub, workshop tools).
- Note whether you plan a remodel in the next 12 to 24 months.
- Decide whether you want “future capacity” for a second EV or bigger equipment later.
If you are planning a remodel that changes appliance locations, this is also the moment to align your electrical plan with the design.
For example, if you are redesigning a kitchen layout, you will want circuit planning to match the appliance package and lighting plan.
If it helps to visualize the scope of kitchen changes that can drive electrical needs, here is a useful reference page on San Jose kitchen remodeling that shows how quickly a modern kitchen spec can expand the electrical plan.
Panel Upgrades for EV Charging
Most homeowners looking at an electrical upgrade are doing it for one reason: they want Level 2 charging at home. Level 2 charging typically uses a 208/240V circuit and can range widely in amperage depending on the charger and the vehicle.
Here is the part that surprises people: EV charging is typically treated as a continuous load, which affects how the circuit is sized. In plain terms, that means the breaker and wiring are commonly sized above the charger’s listed current.
What the EV charger usually needs
- A dedicated circuit for the EV charging equipment
- A breaker and wiring sized appropriately for the charger output
- A placement plan that keeps cord runs clean and safe
- Weather protection if the charger is outdoors or in a carport
Two common examples homeowners understand quickly
- A 32 amp charger often aligns with a 40 amp circuit
- A 40 amp charger often aligns with a 50 amp circuit
- A 48 amp charger often aligns with a 60 amp circuit
Actionable guidance: pick your charger based on your car, not the biggest number
Many vehicles have a maximum Level 2 acceptance rate. If your vehicle cannot use 80 amps, installing an 80-amp capable charger may not buy you real-world speed. A right-sized charger paired with a well-designed circuit is often the best value.
If your panel is already near capacity, you have a few paths:
- Panel upgrade with more breaker spaces (and potentially a service upgrade)
- Subpanel strategy if placement and feeder sizing make sense
- Load management that dynamically limits EV charging when the house is using more power
A good electrician will explain which route fits your home, your budget, and your future plans.
Common Eichler Wiring Challenges
Eichlers reward careful planning because the structure is different from most homes. Wiring pathways are not always straightforward, and careless routing can create unnecessary patching or design compromises.
Common challenges include:
- Slab wiring: Many Eichlers have wiring that runs in or near the slab, which limits easy changes.
- Radiant heat interference: If your home has radiant heat in the slab, you need a routing plan that avoids damaging tubing or components.
- Open beam ceilings: There is often no attic, and homeowners understandably do not want surface conduit cutting across a clean ceiling line.
- Access constraints: Fishing wire can be harder, so planning conduit routes through closets, utility chases, or discreet soffits becomes important.
Actionable guidance: design the wiring routes before demolition
If you are remodeling, the best time to run new circuits is when walls are open. A good plan will identify:
- Which walls can be opened without losing signature details
- Where a discreet pathway can carry conduit or cable
- How to minimize visible changes to beams, ceilings, and glass lines
This is where an Eichler-experienced team matters. They know how to get modern performance without turning the home into something it is not.
Grounding, Bonding, and Safety Updates
Even when an Eichler “works fine,” safety standards have evolved. Upgrades are not only about capacity. They are also about reducing shock risk, lowering fire risk, and protecting expensive electronics.
Safety improvements that often come up during an Eichler electrical modernization:
- Grounding upgrades to ensure the electrical system has a proper grounding path
- Bonding corrections so that metal systems in the home are properly bonded where required
- GFCI protection in locations like kitchens, garages, outdoors, and other wet or exposed areas
- AFCI protection in many living areas to reduce certain arc-fault fire risks
- Whole-home surge protection at the panel to protect sensitive equipment and appliances
If you are doing a kitchen remodel, GFCI and AFCI planning becomes especially important because modern kitchens have more circuits and more high-powered appliances than older layouts. This is another reason it helps to coordinate the kitchen plan and the electrical plan together, rather than treating wiring as a last step.
Where to Place EV Chargers in Eichler Garages and Carports
Many Eichlers have carports rather than fully enclosed garages, so EV placement requires extra consideration. The goal is a setup that is safe, weather-appropriate, and convenient to use every day.
EV charger placement checklist
- Mount the charger where the cord reaches the charge port without stretching across walk paths.
- Avoid mounting where the cord crosses a doorway or where it becomes a trip hazard.
- If outdoors or in a carport, choose weather-rated equipment and plan conduit routes that are protected and visually clean.
- Consider the vehicle orientation. Some charge ports are front-left, some rear-right, and it matters.
- Plan for lighting so you can plug in safely at night.
- Think ahead: if you expect a second EV, plan conduit and panel capacity now.
A clean install often uses a simple conduit path along a structural edge, a utility wall, or a discreet side of the carport rather than running wiring across open beams.
Coordinating Electrical Upgrades With an Eichler Remodel
Electrical upgrades are most cost-effective and least disruptive when they are coordinated with the remodel scope. The biggest mistakes I see are (1) choosing finishes before planning circuits, and (2) adding appliances late and discovering the panel cannot support them.
If you are remodeling, consider planning the electrical system around:
- A lighting plan that matches the mid-century aesthetic (layered lighting instead of a few harsh overhead fixtures)
- Kitchen appliance circuits for induction ranges, wall ovens, microwaves, and dedicated countertop circuits
- Bathroom upgrades that may require new circuits for heated floors or higher-powered ventilation
- Exterior needs like landscape lighting, outdoor outlets, and future heat pump equipment

Permits, Inspections, and Code Compliance in the Bay Area
In the Bay Area, electrical work is not just a technical exercise. It is also a permitting and inspection process. Panel upgrades, service upgrades, and new EV circuits commonly require permits, and service changes can require utility coordination.
What to expect:
- Electrical permit through your city or county building department
- Plan review in some jurisdictions, especially if the scope is large
- Inspection after rough work and at final, depending on scope
- Utility coordination for service upgrades or meter work, when needed
- Scheduling reality: timelines can depend on inspector availability and utility scheduling
If you are upgrading service, the utility may need to evaluate whether the infrastructure serving your home can handle the new load. That is why it helps to understand the steps early. Homeowners often find it useful to read the utility’s published guidance before kicking off a major service change.
Cost Factors: What Drives the Price of an Eichler Electrical Upgrade
Every Eichler is a little different, and pricing reflects the constraints and the scope. The same “panel upgrade” can mean very different work depending on whether you are also rewiring, adding EV charging, or relocating equipment.
Cost drivers often include:
- Service upgrade scope (staying the same vs increasing service size)
- Panel location and relocation needs (moving a panel can add significant labor and patching)
- Number of new circuits (kitchen and EV charging add quickly)
- Wiring access difficulty (open beam ceilings and slab constraints can increase labor)
- Trenching or conduit runs for detached routes or carport installations
- Drywall, plaster, or finish restoration after running new wiring
- Upgraded safety devices like GFCI, AFCI, and surge protection
- Permits and inspection requirements that vary by jurisdiction
A homeowner-friendly way to budget: ask for a scope that separates “must do for safety,” “must do for EV charging,” and “nice to do for future-proofing.” That breakdown helps you make decisions without feeling pressured.
Choosing the Right Contractor for Eichler Electrical Work
Eichler electrical upgrades are not the moment for guesswork. You want licensed professionals who understand both code compliance and the realities of Eichler construction.
What to look for
- A licensed electrician who pulls permits and is comfortable with inspections
- Experience with mid century homes and routing constraints
- A willingness to explain the load calculation and circuit plan in plain language
- Clear options, not one take-it-or-leave-it approach
- Coordination skills if your electrical work is tied to a remodel timeline
Questions you can ask that reveal experience fast
- “How will you route the EV conduit in a way that stays visually clean?”
- “What is your plan to avoid issues with slab radiant heat if it is present?”
- “If we remodel the kitchen later, how should we future-proof circuits now?”
- “Can you provide a scope that separates safety, capacity, and convenience upgrades?”
If your project includes a kitchen remodel, this is also a good time to align your appliance plan, lighting plan, and circuit plan so everything is designed as a single system.

Make Your Eichler Ready for EVs and the Next 20 Years of Power Demand
A thoughtful electrical upgrade lets you keep what makes your Eichler special while living comfortably with modern power demands. The goal is not to overbuild. It is to right-size your service, modernize safety features, and plan wiring routes that respect the architecture. If you are adding EV charging, remodeling a kitchen, or electrifying appliances, the best outcome comes from planning early, permitting properly, and working with professionals who understand Eichler constraints.
Quick takeaway
- Start with an electrical assessment that includes service size, panel condition, and routing strategy.
- Treat EV charging as a system decision, not just a charger purchase.
- Coordinate electrical work with remodel timing to reduce patching and change orders.
- Upgrade safety protections like GFCI, AFCI, grounding, and surge protection as part of modernization.
- Choose a contractor who can explain options clearly and has experience with mid century construction realities.
