Off-Grid Living in Weber County, Utah

If you're eyeing unincorporated Weber County, Utah for an off-grid setup, here's what I've found digging through official sources, plus a fair warning: this brief only covers unincorporated county land. If your parcel sits inside Ogden, Roy, Farr West, Harrisville, North Ogden, Plain City or any other incorporated city, that city's own zoning code governs, not the county's, so check with the city first.

Zoning. Weber County Planning Division administers countywide zoning for unincorporated areas, split into agricultural, residential, commercial and manufacturing zones. I could not confirm a general right to live in a tent or yurt on raw land outside an approved dwelling; it's handled zone by zone, so call Planning before you buy or move onto vacant land.

Dwellings, tiny homes, RVs. The county's ordinance defines a "dwelling unit" around sleeping, eating, cooking and sanitation facilities, and treats RVs and campgrounds as a separate use category (there's specific language for a Forest Campground Ordinance covering RV/tent campgrounds). I found no countywide rule allowing an RV as a full-time permanent residence on an ordinary lot, unlike some neighboring counties. Confirm directly with Planning if that's your plan.

Building permits. Weber County has adopted Utah's state construction codes (Utah Code Title 15A) by ordinance, and the Weber County Building Inspection Division handles plan review and inspections for unincorporated parcels. Applications go through the county's online portal.

Septic. This is handled not by the county directly but by the Weber-Morgan Health Department, which has adopted the state's Underground Wastewater Systems Rule (R317-5) with its own local amendments. Health department staff do the site and soil evaluation; percolation testing is done by an independent party after that. Composting toilets aren't addressed separately in what I found, so ask the health department how they're treated.

Greywater. No Weber County specific greywater ordinance turned up. It looks like the county defaults to the state's R317-401 rule, administered by the same Weber-Morgan Health Department. Whether they layer on anything extra locally isn't confirmed, so ask them directly.

Rainwater harvesting. No county rule restricts the state's rainwater collection allowance under Utah Code 73-3-1.5. This one looks straightforwardly permitted, inherited from the state.

Wells. Well permitting runs through Weber-Morgan Health Department alongside septic, though actual well construction still needs approval from the state Division of Water Rights, the state's baseline authority. A neighboring county sharing this same health department lists separate phone lines for septic vs. well permits, which suggests Weber County parcels are handled the same way, though I couldn't independently confirm that on a Weber County page.

Utilities. I found no blanket county policy requiring grid hookups for occupancy. Interestingly, the county's own density formula for subdivisions adjusts lot size upward when the health department says there's no sanitary sewer or culinary water, which tells me the county does plan around off-grid situations for density purposes. But a direct statement on occupancy permits and utility hookups is not confirmed, so this stays an open question for Planning or Building Inspection.

Bottom line: Weber County leans on the state for water and building codes but adds its own layer of zoning and health department review. Nothing here should be treated as legal advice, always verify with the named office before you commit to a piece of land.
