Building a house in Utah typically costs about $180 to $280 per square foot for a basic builder-grade home and $280 to $600 per square foot for a custom home, or roughly $400,000 to $900,000 in total, not counting land and site preparation (HomeGuide, 2026). Lot conditions, size, design complexity and finish level move the number more than anything else.
Cost per square foot in Utah
| Build type | Typical cost per sq ft | What drives it |
|---|---|---|

Land and site costs
Land is priced separately. HomeGuide puts Utah land at roughly $20,000 to $40,000+ per acre on average, with lots around Salt Lake City and Park City often far higher and view lots able to exceed $300,000 per acre. On top of the lot itself, budget for:
- Site prep and excavation: about $1,500 to $10,000 on a typical lot; sloped bench lots can run much higher once retaining walls are involved.
- Utilities: hookup and connection fees when water and sewer are at the street, or a well and septic system on rural land.
- Survey: a new-construction survey is typically a few hundred to a couple thousand dollars.
Five things that move your number the most
- The lot. Slope, soils and utility access can swing site costs by tens of thousands of dollars before the house starts.
- Size and shape. A simple rectangle with a straightforward roof costs less per square foot than a footprint with many corners and roof planes.
- Basement. Common in Utah and usually the cheapest square footage you can add, but it adds excavation and foundation cost.
- Finish level. Cabinets, counters, flooring and fixtures account for the widest cost range in the whole build.
- City and HOA requirements. Impact fees, design standards and required materials vary by city and subdivision.
