Cost to Build a House in Duchesne County, Utah
Building a house in Duchesne 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). 123 single-family homes were permitted here in 2025, and the typical existing home is worth $378,727.
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 Duchesne County
Single-family homes permitted each year, 2000–2025. 2025 is highlighted; the 2008–2011 crash years are darker.
Duchesne County is building 38% fewer homes than it did before the crash, up from a low of 39 in 2016. A thinner builder market can mean fewer bids and longer waits for specialist trades.

Build or buy in Duchesne County?
Building a median-size new home in Duchesne County costs about $201,303 more than buying the typical existing one. That gap is wider than the Utah average of +5.2%, because existing homes here are cheaper than elsewhere in the state.
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 Duchesne County permits (2025)
The average declared valuation was $312,107 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 Duchesne 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.
