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

Zoning & raw-land occupancy

RestrictedJuab County has a countywide Land Use Code enforced by a Planning Commission and Zoning Administrator, with historically large minimum lot/acreage requirements (20 to 160 acres depending on zone) for a single home on unincorporated land. Incorporated towns like Nephi may layer additional ordinances on top. source

Dwellings, tiny homes & RVs

Unclear - verifyNo Juab County-specific rule on tiny homes, yurts, or RVs as dwellings was found; this likely defaults to the general state approach where RVs aren't treated as permanent dwellings. Confirm directly with the county Planning & Zoning Department.

Building permits & codes

RestrictedJuab County's building permit application requires verification of zoning, acreage/frontage, an approved water source, and a wastewater permit before a Building Permit Fee and the state's 1% fee are charged and a permit issued. source

Septic & composting toilets

Unclear - verifyThe county's building permit form confirms a wastewater permit is required before building, but no dedicated Juab County or health district septic page was found. Ask the Juab County Planning office which health authority administers septic permits locally. source

Greywater reuse

Unclear - verifyNo Juab County-specific greywater rule was found; this likely defaults to Utah's statewide greywater permitting process through a local health department, but that has not been confirmed for Juab County specifically.

Rainwater harvesting

Unclear - verifyNo Juab County-specific rainwater rule was found; Utah state law generally allows rainwater collection, with registration requirements varying by volume, but Juab County's own stance is not confirmed.

Private wells & water rights

RestrictedWell drilling and water rights statewide, including in Juab County, are regulated by the Utah Division of Water Rights and State Engineer's office; Juab County's building permit also requires proof of an approved water source before building. source

Living disconnected from utilities

Unclear - verifyNo explicit Juab County policy on off-grid electricity or full utility disconnection was found, but the county's building permit requirements for verified water and a wastewater permit suggest occupancy approval depends on those two items regardless of grid-power status. source
