Davis County handles building permits only for unincorporated areas, while incorporated cities like Layton and Bountiful maintain their own independent building and planning departments. The county enforces specific hillside and sensitive lands ordinances for development in the foothills of the Wasatch Range.
How this fits with the state
The state authority here is Utah Division of Professional Licensing. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
