Electricians in Herriman, Utah
John Stocking planted them in the 1850s. Everything else out here has changed — the Butterfield Settlement became a town of 1,523, then a city of 55,000, and the alfalfa on the bench became Rosecrest. We wire all of it: the century-old parcels off Main Street, the 1998 Rose Creek builds, and the panels going in above Blackridge this month.
Section One
In the spring of 1851, four men — Henry Harriman, Thomas Jefferson Butterfield, John Jay Stocking, and Robert Cowan Petty — moved onto the ground under the Oquirrh Mountains that we now call Herriman. They didn't come blind. Butterfield had found a stream running out of a canyon on the west side, and the growing conditions there beat what the group had been working in West Jordan. For a while the place carried his name: Butterfield Settlement. The canyon still does.
Fort Herriman went up in 1854 or 1855 — the records disagree — as protection against the Native people whose land this was. At its gate, John Stocking planted two black locust trees. They are still alive. In 1858, with Johnston's Army approaching, the settlers pulled out; they were back the same year. The townsite was surveyed afterward and named Herriman, in honor of Henry Harriman, with a spelling that drifted a letter along the way and never drifted back.
For nearly a century and a half, Herriman was farms. Then, in the span of one generation, it became the fourteenth-largest city in Utah.
1851 – 2020The turn came in the late 1990s. Rose Creek Estates broke ground on the first true subdivision in 1998, and residents who could see what was coming petitioned to control it themselves — Herriman incorporated as a town on June 1, 1999. Rosecrest, the land developer owned by Sorenson Companies, drove the large-scale residential build-out that followed. In 2007 a lawsuit cleared the way for Herriman to annex roughly 4,000 acres from neighboring Bluffdale, which opened more housing ground and pushed the population past the threshold to be reclassified from a town into a city.
The numbers tell it plainly: 1,523 residents in 2000, and 55,144 at the 2020 census. Herriman today is a third-class city in the Salt Lake City metro — master-planned, densely suburban, and pressed right up against the mountains, with trailheads and reservoirs a few minutes from most driveways.
Section Two
No record we've found pins the exact date the first wire was energized in Herriman, and we'd rather say that than invent a year. What the record does give us is a floor: the 1879 rock building in the old settlement was lit by kerosene lamp. So as of 1879, this was a lamp-oil town.
The likely path in is geography. Herriman sits at the mouth of Butterfield Canyon, and over that ridge is Bingham Canyon — a mining district that needed enormous amounts of power decades before any farm did, and that pulled transmission and generation onto the west side of the valley to get it. Rural service in the unincorporated Salt Lake County settlements generally followed the utility build-out of the 1910s and 1920s, with the more remote farmsteads picking up service in the New Deal rural-electrification years. Herriman, a small agricultural community of a few hundred people, would have been wired in that same long tail — not first, and not last.
Today the answer is simple. Rocky Mountain Power, the PacifiCorp division that serves most of the Wasatch Front, is the electric utility for Herriman. Natural gas is Dominion Energy. City-side, Herriman handles streetlighting and the permitting that any service change, panel swap, or new circuit runs through — and because so much of the housing stock went up inside a twenty-year window, permit-era matters more here than it does in most Utah cities.
That's the practical takeaway. In a town where the buildings range from 1870s stone to a townhome finished last quarter, the wiring behind the drywall isn't one story. It's about five of them.
Section Three
Herriman didn't grow gradually, so its electrical problems don't average out. They cluster hard by era. Here's what we actually find, sorted by when the house went up.
The handful of surviving farmhouses, outbuildings, and stone structures near old Herriman have been added onto for a hundred years, usually without a plan. We open these up and find 60-amp fuse services feeding a 2020s kitchen, ungrounded two-prong receptacles on cloth-jacketed conductors, and shop or barn feeders buried at whatever depth someone had a trench for.
The fix is rarely "replace everything." It's a proper 200-amp service, grounding and bonding brought to current code, and a phased rewire of the circuits that carry real load.
Watch for: ungrounded circuits · fuse panels · undersized outbuilding feedsThese are the homes that turned Herriman into a town, and they're now old enough to need attention. Builder-grade 150-amp panels, unfinished basements that got finished by an owner without a permit, and no AFCI protection anywhere except where a later remodel forced it. Nearly all of them were built before anyone imagined a car charging in the garage.
Add a Level 2 EV charger, a hot tub, and a heat pump to a 150-amp service and you are out of room — that's the single most common call we take from this era.
Watch for: maxed 150A service · unpermitted basement circuits · no AFCIVolume construction on a schedule. The wiring is generally to code but installed fast: loose neutrals in backstabbed devices, can lights buried in insulation, and garage subpanels sized for exactly the load on the day of inspection and nothing more. Multi-family and townhome stacks in this range share walls, which means a nuisance trip is often somebody else's appliance.
Watch for: backstabbed devices · tight subpanels · shared-wall troubleshootingNewer homes bring newer work: rooftop solar interconnection and load calculations, battery backup, EV circuits run correctly the first time, smart panels, and low-voltage that the builder either roughed in badly or skipped. On the highest bench lots, we also deal with long service runs and detached-garage feeds.
Watch for: solar & battery interconnect · load calcs · long feeder runsHerriman sits at roughly 5,000 feet against a mountain front, and the canyon winds that come down out of Butterfield are hard on overhead service drops, weatherheads, and anything mounted outside. High-altitude UV cooks meter-base gaskets and outdoor conduit faster than it does down in the valley. The dry, alkaline west-bench soil is unkind to ground rods. And after the fire seasons this bench has had, exterior electrical condition is not a cosmetic issue.
Surge protection at the panel is worth more here than most places — end of a long distribution run, exposed terrain, summer storms off the Oquirrhs.
Watch for: weatherhead damage · UV-degraded conduit · corroded grounding · surge eventsSection Four
