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

Zoning & raw-land occupancy

Varies locallyCache County has 19 incorporated municipalities, each with its own zoning and land use rules, so what's allowed on raw land depends heavily on which city or unincorporated area you're in. In unincorporated areas, Cache County's Title 17 zoning code governs and requires a Zoning Clearance before building, but no clear countywide rule on tents, yurts, or living in an RV on raw land was found, so that point is not confirmed and worth a direct call to Planning and Zoning. source

Dwellings, tiny homes & RVs

RestrictedCache County's zoning code defines and regulates manufactured/factory-built housing, and those units have to meet zoning district standards. Whether RVs or tiny homes on wheels can be used as a permanent or temporary dwelling isn't spelled out clearly in Cache County's own code, so I'd confirm directly with the county's Planning and Zoning office before counting on it. source

Building permits & codes

RestrictedA permit is required for new homes, additions, sheds over 200 square feet, shops, garages, and commercial construction, and you need an approved Zoning Clearance and Site Plan before a building permit is issued. Cache County only issues permits for unincorporated land, since each incorporated city runs its own building department, and since January 2022 unincorporated construction also needs a Pre-Occupancy Checklist signed off by Public Works and the Fire District before you can move in. source

Septic & composting toilets

RestrictedThe Bear River Health Department handles septic permitting for Cache, Box Elder, and Rich counties, and any new or altered septic system needs a permit based on soil conditions, site plan, and a percolation test. Composting toilets aren't specifically addressed in the Cache County sources I found, so whether they're accepted as an alternative is not confirmed, this would default to the state's general septic rules unless the health department says otherwise. source

Greywater reuse

RestrictedI couldn't find a Cache County or Bear River Health Department page specifically addressing greywater permitting, so it appears the county just defers to the state rule under Utah Admin. Code R317-401. Whether the health department has its own additional greywater procedures beyond that state baseline is not confirmed, so check with Bear River Health Department directly.

Rainwater harvesting

Generally allowedThere's no Cache County ordinance found that restricts or changes the state's rainwater harvesting allowance under Utah Code 73-3-1.5, so the county appears to simply follow the statewide rule with no extra local permitting layer.

Private wells & water rights

RestrictedWell drilling permits and water rights filings in Cache County go through the state, via the Utah Division of Water Rights (State Engineer), not through any county office. The Cache Water District handles long-term water planning and conservation policy for the county but isn't the permitting authority for an individual well.

Living disconnected from utilities

Unclear - verifyCache County's Pre-Occupancy Checklist and Certificate of Occupancy process, run through Public Works and the Fire District, suggest all permit conditions must be met before you can occupy a structure, but whether that specifically forces a grid utility or sewer hookup versus accepting an approved well and septic system in lieu of hookup is not confirmed in the sources I reviewed. I'd call the Cache County Building Department directly to get a straight answer before planning a fully off-grid setup. source
