Gresham grew up in a hurry. The area was first settled in 1851 as Powell's Valley, but the population barely moved until the 1960s, then roughly tripled every decade, from about 3,944 residents in 1960 to 68,234 in the 1990 Census. Today Gresham is the fourth-most populous city in Oregon, with 114,247 people at the 2020 census, and it serves as the economic center for eastern Multnomah County. What that growth curve tells an electrician is simple: most of Gresham's housing went up during the 1960s-through-1990s suburban boom, with a smaller, older core in the Historic Southeast neighborhood.
That era mix drives most of our calls. A large share of Gresham homes are roughly 35 to 65 years old, right in the window where original 100- to 125-amp service panels, mid-century service equipment, and older breaker brands are common and often near the end of their useful life. Homes from that stretch can carry panel types that insurers and inspectors now flag, including Zinsco and Federal Pacific equipment. Nobody publishes a Gresham-specific count, so we treat it honestly: these issues are typical of homes of this era, and the only way to know what's in your panel is to open it and look. A meaningful share of homes were also built in the 2000s and 2010s, and with the MAX Blue Line running through the city, a lot of Gresham households are commuters, which makes Level 2 EV charger installs common in the newer subdivisions.
The part homeowners don't realize until mid-project: in much of Oregon, permits default to the county or state, but the City of Gresham Building Division issues residential electrical permits and performs the inspections itself. Its permit forms are titled "Electrical Permit Application Gresham/East Multnomah County," meaning the program serves the city plus unincorporated East Multnomah County. Under Oregon law, in most cases the licensed electrical contractor, not the homeowner, pulls the permit. Gresham inspects daily between 8:30 am and 3:30 pm and offers a same-day inspection when the request is in before 6:30 am, so we can often keep a job moving.
