Read this before you act on anything below. This is my researched starting point for Daggett County, UT, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesDaggett County, UT

Zoning & raw-land occupancy

RestrictedDaggett County has an active countywide zoning ordinance administered by the Planning & Zoning Commission; raw-land camping as a permanent residence isn't an established allowed use, and occupancy of any structure requires a certificate of occupancy. source

Dwellings, tiny homes & RVs

RestrictedThe county's accessory-building ordinance defines and restricts 'habitation' in agricultural accessory buildings, and RVs/mobile homes need a building permit before setup. Claims that tiny homes need lots meeting utility standards are not confirmed against official ordinance text. source

Building permits & codes

RestrictedCounty code section 8-3-4 requires a permit for nearly all construction, alteration, or setup of structures (small exemption for ag buildings and accessory buildings under 200 sq ft); occupying a structure without a certificate of occupancy is a misdemeanor per the county. source

Septic & composting toilets

RestrictedTri-County Health Department permits septic (OWTS) installation, repair, and use in Daggett County; new/alternative wastewater technologies must first be approved by the Utah Department of Environmental Quality before local permitting is possible. source

Greywater reuse

Unclear - verifyNo Daggett County or Tri-County Health page specifically addresses greywater; it appears to default to Utah's statewide R317-401 permit rule through the local health department. Confirm directly with Tri-County Health.

Rainwater harvesting

Generally allowedNo Daggett County ordinance restricting rainwater harvesting was found; it appears to follow Utah's statewide rainwater collection law. source

Private wells & water rights

RestrictedWells fall under the state Division of Water Rights process, but Daggett County requires a well-water approval letter from Tri-County Health Department as part of the building permit application. source

Living disconnected from utilities

RestrictedIn unincorporated Daggett County, an approved private well and septic can substitute for utility hookups, but a certificate of occupancy is still required; in the Dutch John Planning District, municipal water and sewer connection is mandatory, so full disconnection isn't allowed there.
