Off-Grid Living in Box Elder County, Utah

I've been digging into what off-grid living actually looks like in Box Elder County, Utah, and the short version is: it's doable, but you're dealing with layered rules from the county, the state, and (if you're in a town) the municipality too. Here's what I found.

Jurisdiction matters a lot here. This brief covers unincorporated Box Elder County, governed by the county's Land Use Management & Development Code. If you're inside Brigham City, Tremonton, Plain City, or another incorporated town, that town's own zoning and building code takes over and can be quite different (Plain City, for instance, has its own explicit RV-occupancy limits).

Zoning and raw land. Box Elder County has countywide zoning in unincorporated areas, administered by Community Development (Planning & Zoning). That means simply parking a yurt or tent on raw land isn't a default-legal option like it might be in a county with no zoning at all; it falls under zone-specific rules you'd need to check with the county directly.

Dwellings, tiny homes, and RVs. The county appears to handle these case by case: a foundation-built tiny home gets treated as a standard dwelling under the state construction code, while a wheeled tiny home or RV is generally treated as an RV, subject to zoning allowances and utility hookups. Incorporated towns can set their own stricter RV-occupancy caps, so if you're in a town, ask that town's office.

Building permits. The county's Chief Building Official enforces the state construction code. I found that permit processing runs 7 to 10 business days once documents are complete, and inspections need 24-hour notice. Permits also get tied to lot conformity, so a "restricted lot" designation can block a permit until zoning issues are cleared.

Septic. This one is handled by the Bear River Health Department (BRHD), not the county directly. A septic permit is required before you build, alter, or repair a system anywhere sewer isn't available, and BRHD reviews soil and site conditions. Composting toilets aren't addressed anywhere I could find, so treat that as an open question for BRHD.

Greywater and rainwater. I couldn't find a Box Elder County or BRHD-specific greywater rule, so the state's general framework likely applies, but confirm with BRHD. Rainwater harvesting looks fine under the state statute, with no added county restriction I could locate.

Wells and water rights. This is the trickiest piece. Box Elder County sits mostly in Water Right Area 29, which the Utah Division of Water Rights has restricted at times, including a period when new groundwater appropriations beyond a small single-family allowance were closed. Expect real scrutiny here; talk to the Division's regional office before assuming you can just drill.

Utilities. I found no standalone off-grid living ordinance, but practically speaking, occupancy sign-off tends to require an approved water source and septic system, so full utility disconnection isn't clearly addressed either way.
