Cost to Build a House in Wasatch County, Utah
Building a house in Wasatch County, Utah costs about $184/sq ft in 2026 — roughly $323,840–$412,160 for a 2,000 sq ft mid-range home (construction only, land excluded). 786 single-family homes were permitted here in 2025, and the typical existing home is worth $972,087.
That is the Utah statewide rate: no public source measures construction cost county by county, so we don't invent a local premium. What does differ by county is measured below.
How much building happens in Wasatch County
Single-family homes permitted each year, 2000–2025. 2025 is highlighted; the 2008–2011 crash years are darker.
Wasatch County is building more homes now than at any point before the 2008 crash — a genuinely expanding market, which usually means an established pool of builders and subdivision lots, but also competition for crews.

Build or buy in Wasatch County?
Unusually, building a median-size new home in Wasatch County costs about $392,057 less than buying the typical existing one. That gap is narrower than the Utah average of +5.2%, because existing homes here are pricier than in much of the state — which makes Wasatch County one of the stronger cases for building in Utah.
The two sides are not the same product: the build is brand new at the median new-home size for the West, the existing home is typically older and smaller. Lot cost uses Utah's average land share, and local lot prices can be well above or below it. Full Utah build-vs-buy comparison

What builders declared on Wasatch County permits (2025)
The average declared valuation was $927,446 per home, against our $368,000 estimate for a 2,000 sq ft mid-range build. The two measure different things: builders declare a valuation for permit-fee purposes, which routinely understates finished cost, and permits cover homes of every size and finish level. We show both because quoting only the flattering one would be dishonest.

What land adds on top

This is a statewide figure. Lots inside Wasatch County's built-up areas will run above it and rural parcels below, so treat it as an order of magnitude rather than a budget line.
