Zoning & Permits
Utah requires residential building permits at the city or county level. Most jurisdictions have adopted the 2021 International Residential Code (IRC) with local amendments. Always check with your local building department for site-specific requirements.
Off-Grid & Rural Builds
For rural builds, septic permits are required through your local health department. Well drilling requires notification to the Utah Division of Water Rights, which oversees groundwater appropriation and well construction standards statewide.
Energy Code & Weatherization
Utah follows the 2021 International Energy Conservation Code (IECC) as the statewide minimum standard. Requirements address insulation, HVAC efficiency, and building envelope standards for high-desert and mountain climates. Local enforcement varies by jurisdiction.
Local Zoning Tools
Zoning and land use in Utah vary by municipality and county. The Utah land use and zoning laws provides mapping tools, and you can access local ordinances through your city or county planning department for site-specific zoning rules.

If you're unsure about your parcel's status—whether it requires septic approval, falls under specific zoning restrictions, or needs water rights documentation—contact your local building department or county planning office directly. In Utah, cities like Salt Lake City, Provo, St. George, and rural counties across the state all enforce different rules. The resources above are a great place to start.
