Salt Lake County vs Davis County.

Home values

The county medians are close, closer than the reputations suggest: ~$505,500 in Davis against ~$525,700 in Salt Lake County. The surprise is the direction. Davis is the cheaper county even though it carries the higher household income of the two, ~$110,900 against ~$97,500, because Salt Lake County holds the bench premium and the pull of the metro, and Davis is the bedroom county to the north. The medians are close enough that the map inside each county matters far more than the county line.

In Salt Lake County the money runs east to west. The bench under the Wasatch, from Millcreek through Cottonwood Heights and Sandy down to Draper, carries the highest values in the county, and the valley floor and the west side, West Valley City, Kearns, Magna, and much of West Jordan, carry the lowest. A buyer holding the budget under half a million shops west of I-15 or north of downtown, and the price pages show what that looks like street by street: West Valley City under $500K, West Jordan under $500K, and Salt Lake City under $500K.

In Davis the money runs from the south bench out to the west side. The established, higher-priced streets are the south bench cities closest to Salt Lake, Bountiful, Centerville, and Kaysville, nearly filled in and trading on location. The newer, larger homes are out west toward Syracuse and Clearfield, where the West Davis Highway opened the county's last farm ground to building. Layton is the biggest market and sits in the middle of the range. The price pages show what a budget buys: Layton under $600K, Bountiful under $650K, and Kaysville under $700K.

The practical version, for the same monthly budget: Salt Lake County gets you the shorter reach to everything and an older house closer to it, and Davis gets you a slightly lower price, a bigger or newer house on the west side, and a shorter drive to the airport. Neither is the bargain. 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. Both seats land at about ~0.6% effective on a primary home. Utah taxes a primary residence on 55 percent of its market value, and the certified rate that reaches your bill is set by the city and the school district, not the county, so a suburb with a new school bond can run higher than its neighbor while the county line means nothing.

Sales tax is where a gap shows. The combined rate at the register is ~8.45% in Salt Lake City against ~7.25% in Farmington, more than a point apart, because Salt Lake City stacks city, transit, and venue levies on top of the state and county base. Suburbs on both sides sit lower than the capital. On a household that spends a few thousand a month on taxable goods, a point adds up over a year, though it is nowhere near the size of a housing payment. Check the exact rate for any address on the county assessor's site before you commit.

The trade behind the price

What the Davis side buys is a settled county and a short leash to the city. Every Davis city is a quick drive or a FrontRunner stop from Salt Lake and its airport, the household incomes are the highest of the two counties, and the whole county runs on one school district, with mature yards and established streets. What it does not buy is a new house in the heart of town, because Davis is nearly out of edges. New construction is mostly a west-side story now, out toward Syracuse, Layton, and Clearfield.

What the Salt Lake price buys is the metro itself. The airport is in the county, ten minutes from downtown; TRAX and FrontRunner make one car per household realistic in a way it is not in most of Davis; and the biggest employers in the state, Intermountain Health, the University of Utah, the state, and Delta, are all inside the line, so the commute is a valley commute. New homes here are mostly infill and townhomes rather than fresh subdivisions, so compare Salt Lake City townhomes and Herriman new construction on the southwest corner, the one part of the county still building whole neighborhoods, with what Davis is putting up out west.

Elevation and seasons

On weather these two counties are almost the same place. Salt Lake City sits at ~4,300 ft, valley floor and Farmington at ~4,300 ft, valley bench below the Wasatch, both get four full seasons, a July high around ~93 °F in Salt Lake and ~91 °F in Davis, January lows near ~23 °F and ~20 °F, and valley snow that comes and goes while the mountains above hold it for months. They feel the same storms within the same hour. None of that should decide anything between them.

What matters more than the county is the bench. In both, the higher you climb toward the Wasatch, the cooler the summer nights, the more snow lands on the driveway, and the better the view. The Salt Lake bench cities, Millcreek up through Cottonwood Heights and Sandy, and the Davis bench above Bountiful and Centerville, all sit noticeably above the valley floor, and a buyer who cares about that should shop by elevation before county.

Water, air, and the valley floor

Both valleys get the winter inversion, the lid of cold air that traps haze on the 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, and the south end of Davis shares the same basin air. The bench sits above the lid more often than the flats do, which is part of why bench streets cost more. The Local has an honest read on the valley in winter and the lid that sits on it that applies to both counties.

The water is the same body seen from two angles. Both counties front the Great Salt Lake, Salt Lake County at its northwest corner and Davis along its whole west edge, and the lake has been near record lows for years, so its exposed bed and the dust off it are part of the air picture on both sides. Davis gets the better front-row seat: Antelope Island is a Davis state park, and Farmington Bay behind the west-side cities fills with eagles in winter and shorebirds in spring. The Local's Great Salt Lake page explains why the whole valley watches the water level.

Public land and the map

Here is the biggest difference on the map, and it hides in the land rows of the table. Salt Lake County is 73% private and 21% federal, while Davis is only 25% private and 11% federal. That low private share in Davis looks like a mountain county's scarcity but is not: the reason so little of Davis is private is that the Great Salt Lake and Antelope Island, both state and sovereign land and water, fill a large share of the county, not a national forest locking up building ground.

The mountains are where the two counties part for good. Salt Lake County's federal share is concentrated in the Wasatch canyons on the east side, and Big and Little Cottonwood hold four ski areas and the most heavily used trailheads in the state, twenty minutes from the bench. Davis has canyon mouths and trailheads at the top of its bench, walked in the Davis canyons page, but no ski area of its own at all. If the ski canyons are why you are moving to Utah, that is Salt Lake, and Davis is the county you drive out of on a powder morning.

School districts

Salt Lake County runs five districts: Salt Lake City, Granite, Jordan, Canyons, Murray. The lines follow the cities closely enough that the city guide usually tells you the district, and the two big ones, Granite across the center of the valley and Jordan across the southwest, each serve more than a dozen cities. Davis runs one, Davis School District, a single system covering all fifteen cities, which makes the county unusually simple on this front. 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; the guides for Salt Lake City and Layton and the rest tell you which district an address falls in.

Colleges and universities

Salt Lake County is the bigger county for higher education: University of Utah, Salt Lake Community College, Westminster University, with the University of Utah the state's flagship and its biggest research campus. Davis reaches across the county line for its own, Weber State University Davis Campus (Layton), Davis Technical College (Kaysville), so a degree is close without leaving the county, and Weber State's main campus is a short drive north into Ogden. Between them the north Wasatch Front is well covered for a state this size.

Hospitals and the airport

Salt Lake County has 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 the specialist is in Salt Lake County no matter which county you live in. Davis has full local care of its own, Lakeview Hospital (Bountiful), Intermountain Layton Hospital, Holy Cross Hospital Davis (Layton), so routine and emergency care is close everywhere in the county, and for a rare specialty a Davis household is a short drive south to the big Salt Lake centers.

The airport is simple, and it is one of Davis's quiet advantages. Salt Lake City International is inside Salt Lake County, ten minutes from downtown and a Delta hub with direct flights most places, and from Davis it is close behind, ~25 min from Farmington. Davis has no airport of its own, but it does not need one: the hub is a short freeway or FrontRunner run away, which is one of the reasons the south end of Davis holds the price it does.
