Salt Lake County vs Tooele County.

Home values

The gap here is wide and it runs exactly the way you would expect. Salt Lake County's median home value is ~$525,700 against ~$431,600 in Tooele, and unlike some county comparisons the medians and the maps agree: Tooele is the cheaper county almost everywhere inside it. The distance from the jobs is the discount. Every mile west around the Oquirrhs is a mile farther from the airport and the offices, and the price comes down to match.

In Salt Lake County the money runs east to west. The bench under the Wasatch, from Cottonwood Heights and Holladay down through Sandy to Draper, carries the highest values in the county, and the valley floor and the west side, West Valley City, Kearns, and Magna, carry the lowest. A buyer set on staying in Salt Lake County for less shops the west side, and the price pages show what that looks like street by street: West Valley City under $500K, Magna under $400K, and Kearns under $400K.

In Tooele County the money runs with the water and the view. Tooele city and Grantsville sit on the valley floor at the base of the Oquirrhs and the Stansbury Mountains, and the newer, larger homes out in Erda and up against the foothills run higher than the older grid in town. Even at the top of the county's range, though, the same money buys more house and more lot than it does in Salt Lake County. The price pages show it: Tooele under $500K, Grantsville under $550K, and Grantsville under $450K.

The practical version, for the same monthly budget: Salt Lake County gets you a smaller, older place close to the jobs, and Tooele County gets you a newer, bigger one with a drive attached. Neither is the bargain and neither is the splurge; they are two honest answers to the same money. The cost-of-living guide lays the whole state out by region, and the affordability calculator turns either county's median into a number you can shop with.

Taxes, county by county

Property tax is nearly a wash. Utah taxes a primary residence on 55 percent of its market value, and the certified rate at each county seat lands at about the same place: ~0.6% effective on a primary home in Salt Lake City and ~0.6% effective on a primary home in Tooele. What moves the bill is the city and the school district inside the county, a new school bond or a special service area, not the county line itself. Check the exact rate for any address on the county assessor's site before you commit.

Sales tax is where the county line actually shows. The combined rate at the register is ~8.45% in Salt Lake City against ~7.00% in Tooele, because Salt Lake City stacks city, transit, and venue levies on top of the state and county base. On a household that spends a few thousand a month on taxable goods it adds up over a year, though it is a rounding error next to the housing gap.

The trade behind the price

What the higher Salt Lake County price buys is proximity. The airport is inside the county, the three TRAX lines and FrontRunner let a household lean on one car, and the biggest employers, Intermountain Health, the University of Utah, the state, and Delta, are all here. The commute is a drive across a valley, not a drive between valleys, and that is most of what you are paying for.

What the lower Tooele County price buys is room. The county has ~6,941 sq mi of land, and while the vast majority is desert and military range, the buildable strip at the near end is still filling in, so new construction is a live option in a way it is not in a full Salt Lake valley. If a new house and a shop or some acreage matter, start with new construction in Tooele, Grantsville, and Grantsville horse property, and weigh the extra square footage against the miles you will drive to reach a Salt Lake job. If open country is the whole point, the rural-living guide is worth a read before you buy on a well and a septic tank.

Elevation and seasons

On weather, the two counties are close cousins. Salt Lake City sits at ~4,300 ft, valley floor and Tooele at ~4,900 ft, valley floor, a few hundred feet apart, and both get four full seasons: a July high around ~93 °F in Salt Lake and ~92 °F in Tooele, January lows in the low twenties, and valley snow that comes and goes while the mountains hold it for months. Tooele runs a touch drier, sitting in the rain shadow of the Oquirrhs with the west desert beyond it. None of that should decide anything.

What matters more than the county is elevation. In both, the higher you climb toward the mountains the cooler the summer nights and the better the view. On the Salt Lake side that is the Wasatch bench in Sandy, Cottonwood Heights, and Draper; in Tooele it is the foothills under the Oquirrhs and the Stansbury range above Tooele city and Grantsville. Shop by elevation before you shop by county if a cooler night and a long view are what you are after.

Water, air, and the valley floor

Both valleys get the winter inversion, the lid of cold air that traps haze on the valley floor for days at a time in December and January. Salt Lake's is the one that makes the news, because the valley is bigger and the haze sits over more than a million people, but Tooele Valley catches its own when the same still, cold weather settles in. The bench and the foothills sit above the lid more often than not, which is part of why higher ground costs more. The Local has an honest read on the valley in winter and the lid that sits on it that applies on both sides of the Oquirrhs.

The Great Salt Lake ties the two counties together and worries both. Salt Lake County meets it on the northwest, and Tooele County wraps its south shore out past Stansbury Island; the lake has been near record lows for years, and the dust off its exposed bed is part of the air picture for everyone downwind. The Local's Great Salt Lake page explains why the whole region watches the water line, and Stansbury Island is the quiet Tooele-side way to stand on its shore.

Public land and the map

Here is the biggest physical difference between the two, and it hides in one row of the table. Salt Lake County is 73% private and 21% federal; Tooele County is 11% private and 79% federal. Almost four out of five acres in Tooele are federal ground, most of it Bureau of Land Management desert, the Tooele Army Depot, and the Dugway Proving Ground, which is why the county's towns stop where they stop and the map west of them is nearly empty. It is also why the weekend country is enormous: the Bonneville Salt Flats and the Onaqui wild horses are Tooele's backyard.

Salt Lake County's federal share is much smaller, but it is concentrated where it counts, the Wasatch canyons on the east side. Big and Little Cottonwood hold four ski areas and the most heavily used trailheads in the state, about twenty minutes from the bench. Tooele has no ski area and no state park at all; what it has instead is room, the Stansbury Mountains, and a desert that runs on past the horizon. If the biggest ski canyons in the state need to be a short drive away, that is Salt Lake County. If walking out onto empty public land in every direction is the point, that is Tooele.

School districts

Salt Lake County runs five districts: Salt Lake City, Granite, Jordan, Canyons, Murray. The lines follow the cities closely, and the two big ones, Granite across the center of the valley and Jordan across the southwest, each serve more than a dozen cities, so the city guide is usually the fastest way to learn which district an address falls in. Tooele County is far simpler: Tooele County School District covers the whole county, town and desert alike. I do not rate schools, on this page or anywhere on the site. I name the district, link the city guide, and leave the judgment to you and the district's own published data.

Colleges and universities

On higher education the two are not in the same weight class. Salt Lake County has the University of Utah, the state's flagship and its largest research hospital, along with Salt Lake Community College's campuses across the valley and Westminster University on the east bench. Tooele County has a Utah State University regional campus in Tooele and Tooele Technical College, enough for a two-year start or a trade close to home, with the four-year campuses a drive east.

Hospitals and the airport

Salt Lake County holds the medical center of the whole Intermountain West: Intermountain Medical Center, University of Utah Hospital, Primary Children's, St. Mark's, LDS Hospital, Riverton, Alta View, Jordan Valley, Lone Peak. If a specialist matters to your move, there is a real chance that specialist is in Salt Lake County no matter where you live. Tooele County has Mountain West Medical Center (Tooele) for routine and emergency care, which covers the everyday, but for anything specialized a Tooele household drives east to the Salt Lake hospitals.

The airport is entirely a Salt Lake County asset. Salt Lake City International sits inside the county, a Delta hub with direct flights most places, and it is closer to Tooele than to a lot of the Salt Lake suburbs, about forty minutes out I-80. Tooele County has no commercial airport of its own. For a frequent flyer that nearby hub is a genuine mark in Tooele's favor, one of the few big-city conveniences the drive west does not cost you.
