Electrical Panel Upgrade in Seattle, WA
Most electrical panel upgrades in Seattle run $2,200 to $4,500 installed, depending on panel size and service capacity. SPS Pro Services handles upgrades throughout Seattle and King County, with most jobs scheduled within a week and completed in a single day by licensed electricians familiar with older city wiring.


A large share of Seattle homes date back to the 1920s through the 1950s, especially in neighborhoods like Wallingford, Ballard, and Ravenna. Many still run on original 60-amp fuse panels or early 100-amp breaker panels that were never built for modern loads like EV chargers, heat pumps, or induction ranges. Upgrading to a 150 or 200-amp panel brings these homes up to current code and gives you room to add circuits without overloading the system.
What's different about electrical panel upgrade in Seattle
Seattle homes have their own quirks, and after years of visits here we know them well.
Seattle City Light requires a service disconnect and reconnect for most panel upgrades, and SPS Pro Services coordinates that scheduling directly so homeowners aren't stuck waiting on hold with the utility.
A number of pre-1970 Seattle homes still have Federal Pacific Stab-Lok or Zinsco panels, both known for breakers that fail to trip during overloads, which is a common reason insurance companies flag a home during underwriting.
Winter electric heat use and space heater load spikes are harder on undersized older panels, and a 60-amp fuse box in a Seattle bungalow often can't handle a heat pump addition without an upgrade first.

Electrical Panel Upgrade in Seattle — FAQ
Do I need a permit for a panel upgrade in Seattle?
Yes. The City of Seattle requires an electrical permit for any panel upgrade, and the finished work has to pass inspection by a city electrical inspector before it's approved. SPS Pro Services pulls the permit and schedules the inspection as part of the job, so you don't have to deal with the paperwork.
How long does a panel upgrade take on an older Seattle home?
Most upgrades take one full day, though homes in areas like Ballard or Ravenna with knob-and-tube remnants or undersized subpanels sometimes need extra time to bring branch circuits up to code. Your electrician will flag any of that during the initial inspection, not after work starts.
Will Seattle City Light shut off my power during the upgrade?
Yes, a short disconnect is required so the main service can be safely worked on. SPS Pro Services schedules this directly with Seattle City Light and times the work to keep the outage as short as possible, usually just a few hours.
My home has a Federal Pacific or Zinsco panel — is that a bigger job?
Not necessarily bigger, but it's a priority. These panels, common in Seattle homes built before 1970, are known for breakers that don't trip properly during a fault. Replacement is straightforward and is one of the more common calls we get from Wallingford and Ballard homeowners after a home inspection flags it.
