Electrical panel upgrade in Hillsboro, OR
Most of Hillsboro is newer than people expect, so the panel work here often means adding capacity for EV charging and heat pumps rather than rescuing old wiring. The historic core is the exception.

Hillsboro grew up with the Silicon Forest, and its housing shows it. Much of the city is newer subdivision stock around Orenco Station, South Hillsboro, and Tanasbourne, with only a small slice of genuinely old homes in the downtown historic core. That flips the usual panel conversation: instead of hazard replacement, the common need here is headroom, a service that can take on a Level 2 EV charger, a heat pump, or a shop subpanel without tripping.
When a code-era home does run short on capacity, an electrical panel upgrade or a well-placed subpanel is the clean fix. In the older core, where undersized services and aging equipment do turn up, the upgrade plays its more traditional role.
What the upgrade involves
A panel upgrade replaces your existing service with a higher-capacity panel, typically 200 amps, with new breakers and grounding to current code. On a newer Hillsboro home, we first check whether you actually need a full upgrade or whether a subpanel and a couple of dedicated circuits will carry the new load. We run the math before we recommend anything.
If you are in the downtown core and your home predates the growth boom, we read the service and equipment honestly and lay out whether replacement is warranted.
Cost and what moves it
Panel upgrades across the metro run between $2,500 and $7,500. A newer Hillsboro home with easy access and a modern meter base tends to sit lower in that band; an older-core service that needs entrance or grounding work sits higher. We quote from what we actually see. Our panel upgrade cost guide explains each factor in detail.
Permitting inside the City of Hillsboro
Hillsboro runs a delegated electrical program: the city issues the residential electrical permit and performs its own inspections through its permitting center, rather than deferring to Washington County or the state. We pull the city permit and a city inspector signs off, so your upgrade is on record and code-compliant.
New-build service, and your utility
Most Hillsboro homes near Orenco Station, South Hillsboro, and Tanasbourne were built with underground service rather than an overhead drop, so the meter and the main panel usually sit on an exterior wall with the feed coming up from a pad or vault. That is generally cleaner to work on than a 1920s roof mast, but it does not automatically mean spare capacity. A builder sizes a panel for the house it sold, not the heat pump, charger, and shop you add years later, so we still open it, read the loads, and check for open slots before we call it ready.
Hillsboro's electricity comes from Portland General Electric across the city, so if an upgrade means a heavier service, the meter disconnect and reconnect are arranged with PGE and timed to the city inspection. In the older downtown core, where some homes still run overhead services and smaller panels, that coordination looks more like it does in an older city. Either way, scheduling the utility around the work is part of what we handle.
Hillsboro panel upgrade questions, answered
My home near Orenco is newer. Do I even need a panel upgrade for an EV charger?
Often not. Many of Hillsboro's post-2000 homes were built with enough panel capacity to add a dedicated Level 2 charger circuit without a full upgrade. We check the panel and the loads you already run, then tell you honestly whether a straight circuit will do or whether adding capacity is worth it. Either way you get a clear quote first.
Can a panel upgrade add a subpanel for my garage or shop at the same time?
Yes, and in Hillsboro's newer homes that's a common pairing. If you're upgrading the main service anyway, adding a subpanel for a garage, shop, or ADU while the panel is open is efficient. We size the subpanel and feeder against your total load and permit it with the main work through the city.
Does Washington County handle my Hillsboro panel permit?
No. Hillsboro runs its own delegated electrical program, so the permit and inspection go through the City of Hillsboro's permitting center, not the county or state, for work inside city limits. We handle that filing and the city inspection as part of the job.
My Hillsboro home has underground service. Does that make a panel upgrade easier?
Often, yes. Most of Hillsboro's newer subdivisions were built with underground service, so the meter and panel sit on an exterior wall and there is no aging roof mast to rebuild, which can keep the job cleaner and the outage shorter. It does not guarantee spare capacity, though, so we still run a load calculation. Your power comes from PGE, and we coordinate any service disconnect with the utility and the city inspection.
