Sunnyvale Electrician for Eichler Retrofits and Panel Upgrades
Eichler built Sunnyvale first.
Eichler built Sunnyvale first.
Sunnyvale homes, panels, and service upgrades
Eichler built Sunnyvale first. We rewire it now. Sunnyvale is where Joseph Eichler built first (Manor I in 1949) and roughly 1,100 Eichlers still stand across 16 tracts, the second-largest concentration in California. We retrofit them around the architecture: slab-on-grade radiant heat, glass curtain walls, original Zinsco panels. Panel upgrades, FPE and Zinsco replacement, EV chargers, and heat-pump-ready service for the rest of the city too, all on PG&E delivery and SVCE generation.
Quick answer
Cali Rollin Electric is a C-10 electrical contractor, #1144031, working throughout Sunnyvale. Three things anchor the work here. First, this is the birthplace of the Eichler: Joseph Eichler's first development, Manor I, broke ground in 1949, and roughly 1,100 Eichlers survive across 16 tracts, the second-largest concentration in California. They are slab-on-grade with radiant-heat piping cast into the concrete, so drilling the slab without a plan can puncture it, and original service is 100A. Second, FPE Stab-Lok, Zinsco, and Pushmatic panels across the 1950s to 1970s tract belt, where some insurers may flag these panels or request replacement. Third, PG&E delivery with SVCE generation: Sunnyvale is not a municipal-utility city like Palo Alto or Santa Clara. A 100A to 200A upgrade is quoted after a site and load review. Permits go through the One-Stop Permit Center at 456 W. Olive Ave. via E-OneStop, and the city carries no fire hazard severity zone, so nothing here needs fire-hardening scope.Call (408) 614-4451Free assessmentC-10 #1144031.

The city where the Eichler began
Sunnyvale is the city where the Eichler began. Joseph Eichler's first development, Manor I, broke ground here in 1949, and the first architect-designed Eichlers, by Robert Anshen, followed in Manor II in 1950. Roughly 1,100 remain today across 16 tracts: Manor I and II, Fairbrae and the Fairbrae Addition, Fairwood and the Fairwood Addition, and the rest of the citywide footprint. That mid-century housing legacy shapes nearly every panel and service call we run here.
What changes the job inside a Sunnyvale Eichler
The original service was never sized for a Level 2 EV charger, a heat pump, an induction range, and a smart panel running at once, so modern electrification typically requires a panel upgrade before a single new circuit lands. Copper or wrought-iron radiant piping runs through the concrete slab, and drilling without a precise plan can puncture it, which is an expensive failure. There is no crawl space and no attic clearance: low-pitch or flat roofs and exposed-rafter ceilings leave no concealment routes, and tongue-and-groove plank ceilings double as the finished interior, so there is no hidden-run option. Original panels are predominantly Zinsco or Sylvania-Zinsco, which is both a safety concern and a capacity ceiling. Every Sunnyvale Eichler retrofit therefore starts the same way: a service-capacity assessment, a load calculation against the owner's electrification roadmap, and a routing plan that respects the slab, the ceiling, and the glass. When the roadmap is long and the wall space is not, a SPAN load center moves more of the load management into the panel itself, which suits a house with nowhere to hide a subpanel.
The post-war tract belt has its own panel problem
FPE Stab-Lok, Zinsco and Sylvania-Zinsco, and Pushmatic panels are common across the 1950s to 1970s tract housing in Cherry Chase, Lakewood Village, Sunny Manor, Raynor, and Ponderosa. Some insurers may flag FPE and Zinsco panels or request replacement; requirements vary by carrier and property. We scope all three anchors at the on-site assessment. If a Cherry Chase home needs a panel upgrade for a heat pump, a Zinsco swap is overdue from the insurer's letter, and an EV-ready 240V circuit is on the wish list, one trip and one permit handles the whole sequence.
PG&E delivers. SVCE generates. Not a municipal utility.
Electricity is delivered by PG&E over PG&E poles and wires, but the generation supplier is Silicon Valley Clean Energy, and Sunnyvale has been an SVCE founding-member jurisdiction since the April 2017 phase-in. GreenStart, the default tier, is 100% carbon-free. That split matters on a service job: the disconnect and reconnect go through PG&E, while the electrification rebates run through SVCE. We know which calls go where, and we make them.
Permits, E-OneStop, and one quirk to plan around
Permits run through the City of Sunnyvale One-Stop Permit Center at 456 W. Olive Ave., 2nd floor, with everything flowing through the E-OneStop portal that relaunched on Accela in August 2024. Review timing depends on the scope, corrections, and the City's current workload. The Sunnyvale-specific quirk: an EV charger on an existing panel can be permitted online over the counter, while an EV charger that needs a new panel requires an in-person appointment. We plan around that instead of finding it at submission.

Sunnyvale Panel Upgrade
100A to 200A service upgrades on Sunnyvale's 1950s to 1970s tract housing and Eichler stock. PG&E disconnect and reconnect coordinated by our team. EV-ready, heat-pump-ready, insurance-compliant. Required permits coordinated.
FPE and Zinsco Replacement
Insurance-driven panel replacement for Federal Pacific Stab-Lok, Zinsco / Sylvania-Zinsco, and Pushmatic, common across Cherry Chase, Lakewood Village, Sunny Manor, Raynor, Ponderosa, and the original Eichler tracts.
EV Charger Installation
Level 2 on a dedicated 240V circuit: Tesla, Rivian, Ford, ChargePoint, Emporia, and every other major brand. One Sunnyvale quirk to plan around: a charger on an existing panel permits as online over-the-counter, while a charger needing a new panel requires an in-person appointment.
Aluminum Wiring Remediation
Aluminum branch wiring turns up across the post-war tract belt alongside the panel-era finds. Correct terminations at every connection point are the entire job, and we read what is actually in the walls before quoting a scope.
Knob-and-Tube Replacement in Sunnyvale
Pre-1940 housing concentrated in the Heritage District around Murphy Avenue, roughly 69 documented historic homes where pre-1940 wiring is the rule rather than the exception. Rewires documented so an insurer can clear the file.
ADU Electrical
Sunnyvale is a high-volume ADU city under its certified Housing Element. Separate meter or subpanel, 240V EV pre-wire, and frequently a main service upgrade, because the existing service rarely has room for a second dwelling.
Battery Storage Installation
Residential battery storage for grid-outage continuity, with PG&E SGIP as the main upfront incentive. Sunnyvale is not in a fire-zone tier, so the general-market SGIP amount is modest and worth checking before you scope the project.
Pre-Sale Electrical Clearance
Inspection, deficiency report, and repair for real estate transactions. In the Heritage District and the Eichler tracts these regularly surface original panels and ungrounded circuits an insurer may flag during a transaction.
Emergency Electrical, Sunnyvale
Panel failures, burning smell, tripped mains, dead circuits. Call to confirm current emergency availability, whether it is an original Zinsco panel arcing in Sunnyvale Manor or an FPE Stab-Lok failure in Cherry Chase.

What shapes your electrical quote
Equipment condition, service capacity, wiring routes, access, planned loads, and finish restoration determine the scope. A panel replacement is different from a service upgrade or meter relocation.
We confirm any site-visit or diagnostic charge before scheduling. Your written proposal identifies the work, permit and utility responsibilities, exclusions, and a lump-sum price before you approve it.
Permits & utilities
PG&E delivers. SVCE generates. Not a municipal utility.

Permits, E-OneStop, and one quirk to plan around
Permits run through the City of Sunnyvale One-Stop Permit Center at 456 W. Olive Ave., 2nd floor, with everything flowing through the E-OneStop portal that relaunched on Accela in August 2024. Review timing depends on the scope, corrections, and the City's current workload.

We plan around that instead of finding it at submission.
Rebates & incentives
Sunnyvale programs worth checking before you buy
Because PG&E handles delivery and SVCE handles generation, incentives from both can apply, and Sunnyvale adds a city supplement on the heat pump side. Several federal residential energy credits have expired, so the programs below are the ones worth checking today. Rebate program rules, caps, and eligibility change without notice. Cali Rollin Electric does not administer these programs and cannot guarantee any specific rebate amount. Always confirm current terms on the program's official page before applying.
SVCE Home Rebates (core plus add-ons)
Silicon Valley Clean Energy's residential rebate portal: heat pump HVAC, heat pump water heater, induction range, and panel-upgrade rebates for SVCE customers, and Sunnyvale is a founding-member jurisdiction. The same application also covers the electrical work that makes those appliances possible, main-panel upgrades and dedicated-circuit prewiring, stacked into one submission.
Open program page ↗
Sunnyvale city rebate (heat pump HVAC supplement)
Sunnyvale's city supplement for heat pump HVAC stacks on top of the SVCE Home Rebates application with no separate steps: the single SVCE application handles both. The city supplement runs on a limited, first-come budget, so treat it as a bonus on top of the base SVCE rebate rather than a guaranteed amount.
Open program page ↗
PG&E Residential EV Charging Rebate
PG&E's rebate for a permitted residential Level 2 EV charger: a standard tier open to eligible EV and plug-in hybrid owners, plus an income-qualified Rebate Plus tier that can also help cover a panel upgrade. Funded by California's Low Carbon Fuel Standard rather than ratepayer dollars, and it can stack with the SVCE EV programs where eligible.

SVCE EV rebate
An income-qualified rebate for used or new EV and plug-in hybrid purchases. Eligibility and any vehicle price limits are set by SVCE, so confirm current terms on the SVCE site before you count on it.
Open program page ↗
PG&E SGIP (battery storage)
The Self-Generation Incentive Program for residential battery storage. The general-market tier is modest, and the larger equity-tier incentives are reserved for income-qualified households or homes in a high-fire-risk area. Sunnyvale is not in a fire-zone tier, so ask what tier your project qualifies for before counting on a specific amount.

California Energy Smart Homes
A statewide incentive for whole-building all-electric single-family projects: heat pump HVAC and heat-pump water heating together, with a panel-upgrade bonus riding on the full conversion rather than a per-measure rebate. 2026 funding is currently fully subscribed, so new applications are waitlisted.

Working across Sunnyvale.
From the Heritage District to the Eichler tracts
Six neighborhoods, three eras, and one consistent question: what is the service, and what is on the panel door. The answer changes the whole scope.
Sunnyvale Manor I and II
1949 and 1950, the original Eichler tracts
Joseph Eichler's first real-estate development. Manor I (1949) predates the architect-designed Eichler look; Manor II (1950) is where Robert Anshen established the post-and-beam, atrium, glass-wall canon the rest of the portfolio inherited. These are the homes that started everything, and they still need every Eichler-retrofit consideration today.
Fairbrae
Eichler tract, 1958 to 1961, roughly 78 original homes plus the Addition
Anchored by the member-owned Fairbrae Swim and Tennis Club. Slab-on-grade construction with copper or wrought-iron radiant piping in the slab, original 100A service, and original Zinsco panels. Almost every modern electrification project here starts with a panel upgrade.
Fairwood
Eichler tract, 1961 to 1962, roughly 215 homes
Near South Wolfe Road in the Birdland area. Claude Oakland-designed Eichlers with the classic post-and-beam, atrium-plan, slab-on-grade signature. EV charger upgrades almost always require a panel upgrade, because the original 100A service was never sized for modern load.
Cherry Chase
94087, roughly 2,500 homes, 1950s to 1960s
The premium-tier Sunnyvale tract, an Eichler-and-ranch mix served by Cupertino Union School District, which is part of what drives the price premium. FPE Stab-Lok and Zinsco panels are still common here, and the 1950s and 60s service entrances are not sized for a modern electrified load.
Heritage District
Pre-WWII downtown core, roughly 69 documented historic homes
Around Murphy Avenue, bounded roughly by El Camino to the south, Mathilda west, Central Expressway north, and Fair Oaks east. The oldest documented housing stock in the city, with the highest concentration of knob-and-tube remnants and ungrounded circuits. Insurance and pre-sale clearance work is common here.
Birdland
North Sunnyvale, bird-themed streets
Flamingo, Kingfisher, and the surrounding streets, adjacent to the Fairwood Eichler tract. A mix of mid-century tract housing and Eichler-adjacent homes, with FPE and Zinsco panels still common through the area.
