Is it legal here?

Zoning
Box Elder County zones land outside its towns and publishes its zoning map. Our free lookup shows the district for any address.
Building code
Utah has a mandatory statewide building code: new homes must meet the 2021 International Residential Code with Utah's amendments, and no county can opt out. Your county or city building department issues the permit and does the inspections; the state does not.
Rainwater
Allowed with limits. Check the state's rules before you size a tank.
Composting toilets
Allowed with a permit and an approved unit.
Water rights
Water belongs to whoever claimed it first. A new well or pond may need a state permit, and a creek may already be claimed.
