Charging and panel work for single-family homes, ADUs and the neighborhoods growing along SR-522.
In Kenmore, WA, most of our calls come down to two projects: EV charger installation and the electrical panel upgrades that support it. The charger adds load; the panel decides whether that load fits.
ADUs and middle housing keep growing along SR-522 and Downtown Kenmore, so a charger here might serve a main house, a carport, or a backyard rental.
A Level 2 charger draws on a 240-volt circuit, and the panel behind that circuit decides how fast an evening charge actually goes, the U.S. Department of Energy's benchmark. Kenmore installs start with the load calculation, then place the unit where the car actually parks, garage bay or carport post.
The Tesla Wall Connector installation we perform includes breaker sizing, mounting, and output configuration, with the unit's automatic load management keeping the panel balanced. That flexibility helps where a charger shares capacity with an ADU's kitchen or laundry, a pairing increasingly common around Kenmore now.
A 240V EV charger outlet installation gives you a dedicated receptacle on its own breaker, wired for the run and ready for any compatible plug-in charger. It also keeps sharing simple when two vehicles take turns in one carport and unplugging needs to stay quick.
Kenmore properties mix attached garages, carports, and shared parking, so outdoor-rated equipment comes up often. We specify weatherproof enclosures and conduit for exposed runs, keep cords off walkways, and label the new circuit at the panel so the setup stays clear for the next owner.
Crowded breakers or a panel with a poor service history point toward replacement. Our electrical panel upgrades swap old equipment for a modern enclosure with clean labeling and spare space, which is what a new charging circuit wants to find.
Many Kenmore houses run on 100 amp service, which fills fast once an EV charger, a heat pump, and an ADU share one building. Moving to 200 amps creates headroom, and the load calculation tells whether that step is needed.
When the constraint sits between the street and the panel, an electrical service upgrade covers the meter base, the service conductors, and grounding, along with the panel itself. PSE serves Kenmore's homes, so we time the change with the utility.
An ADU or detached studio usually makes more sense with a subpanel installation than with a larger main panel alone. A feeder panel near the new space keeps circuits short and organized and preserves spare main-panel room for the charger.
Kenmore is a city in transition, and that shapes electrical work. Single-family homes still anchor the streets, but ADU and middle-housing development keeps growing along SR-522 and around Downtown Kenmore, often behind the same meter as the main house.
Charger placement gets decided case by case here. A garage might serve the main house while a carport or shared pad serves the ADU, and each spot implies a different wire route. Capacity questions follow the same pattern: add a rental kitchen, a heat pump, and a 240-volt charger to a decades-old service, and the headroom disappears quickly. We walk the property, read the panel schedule, and lay out options in plain terms. The aim is a setup that fits how the property lives today, with room for what comes next.
The utility picture is straightforward. Electricity and Natural Gas are provided by Puget Sound Energy, according to the City of Kenmore's utilities page, while Northshore Utility District handles water and sewer rather than electricity, a distinction worth knowing when coordination calls begin. Confirm your providers by address before work is scheduled, and check the bill if the name is unclear. Electrical permits for these addresses are obtained through Washington State L&I's electrical permit and inspection system, whose inspectors work from the 2023 National Electrical Code, and we file the permit and book the inspection as part of the job.
Planning numbers for the most common projects here, drawn from current Seattle-Everett market data. Charging hardware and the state permit fee are separate lines, and these ranges are not quotes - the written estimate after the on-site load assessment is the number that matters. See the full pricing table.
| Service | Typical range* |
|---|---|
| Level 2 EV charger installation, dedicated circuit | $800-$1,500 |
| Complex charger runs and detached garages | $1,500-$3,500+ |
| Electrical panel replacement, like-for-like | $4,000-$9,000 |
| 100 amp to 200 amp panel upgrade | $4,000-$9,000 |
Every project opens with a whole-home load calculation, because EV charging counts as a continuous load under the National Electrical Code. The math tells us whether your panel carries the charger as-is, whether load management solves it, or whether an upgrade is the honest answer, before any money is spent.
Credentials are easy to confirm here: the crew works under licensed, bonded and insured Washington State electrical contractor credentials, documented any hour at Washington L&I's VerifySALI contractor lookup. We also file the electrical permit for Kenmore addresses and handle posting and inspection scheduling ourselves.
Calls reach a person at any hour, which matters when a panel problem and a morning commute collide. Estimates arrive in writing with scope, equipment, and sequence spelled out, so Kenmore homeowners can compare proposals line by line and know exactly what was priced before anyone lifts a tool.
It depends on three things: the capacity your panel can spare, the distance from panel to parking spot, and whether the charger is hardwired or plug-in. Projects that upgrade the panel or serve an ADU cost more. Typical single-charger installations run $800 to $1,500 for the circuit work, with the charger priced separately, and complex runs or panel work extending the total. Pricing follows the site visit.
Not automatically. Some ADU owners share the main house's charger, while rentals with off-street parking often justify a separate circuit. The deciding factor is whether the panel and feeder can carry the extra continuous load, which a load calculation settles.
Usually not. A load calculation decides, and many homes support Level 2 charging with load management or a reduced breaker setting. If the service runs tight, we show the numbers. Our EV charger load management guide covers the middle path.
Electrical permits for Kenmore addresses are issued through Washington State L&I rather than a city counter, covering charger circuits, panel replacements, and service upgrades. We file before work starts, keep the permit posted on site, and schedule the inspection after.
Home charging should fit the way your property works, from a two-car garage to a carport pad. Start with the load calculation and the rest follows.
