Read this before you act on anything below. This is my researched starting point for Utah 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 rulesUtah County, UT

Zoning & raw-land occupancy

RestrictedUtah County Planning & Zoning administers a countywide Land Use Ordinance for unincorporated areas; temporary uses like raw-land camping need an application, and cities within the county set their own separate zoning. source

Dwellings, tiny homes & RVs

RestrictedRVs and similar structures are treated as temporary uses requiring a permit in unincorporated county land; county-specific size/duration standards for tiny homes were not confirmed, so the state baseline classification applies unless Planning & Zoning says otherwise. source

Building permits & codes

RestrictedUtah County Building Division enforces the State Construction Code for unincorporated areas and requires permits before construction or system work; properties inside cities follow that city's code instead. source

Septic & composting toilets

RestrictedUtah County Health Department's Environmental Health division administers onsite wastewater permitting under the state R317-4 rule; specific tank/setback numbers and composting toilet rules were not confirmed, so ask them directly. source

Greywater reuse

Unclear - verifyNo Utah County-specific greywater page was found; it's presumed to run through the Health Department under the state R317-401 framework, but this is not confirmed, so confirm with Environmental Health.

Rainwater harvesting

Unclear - verifyNo Utah County ordinance on rainwater collection was found; this appears governed entirely by the state rule (Utah Code 73-3-1.5) with no county overlay confirmed.

Private wells & water rights

Unclear - verifyWells and water rights are handled by the state Division of Water Rights; Utah County wastewater applications may require a well permit or water-supply letter, but no county-specific well ordinance was confirmed.

Living disconnected from utilities

Unclear - verifyNo Utah County ordinance explicitly requiring or prohibiting full utility disconnection was found; occupancy approval seems tied to septic/well sign-off rather than grid hookup, but this is not explicitly confirmed.
