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

Zoning & raw-land occupancy

Varies locallyUnincorporated Weber County is zoned agricultural, residential, commercial, and manufacturing with rules set zone-by-zone by the Weber County Planning Division, and it's not confirmed whether living in a tent or yurt on raw land is generally allowed outside an approved dwelling. If your parcel is inside a city like Ogden or Roy, county rules don't apply and you'd need that city's zoning code instead. source

Dwellings, tiny homes & RVs

RestrictedWeber County's code defines a dwelling unit by its sleeping, eating, cooking and sanitation facilities, and treats RVs and campgrounds as a separate use category from dwellings, including a specific Forest Campground Ordinance for RV/tent camping in resort zones. Whether you can legally live full-time in an RV or tiny home on an ordinary residential or ag lot outside a recognized campground is not confirmed in the county's official materials, so I'd call Weber County Planning before counting on it. source

Building permits & codes

RestrictedWeber County adopts the state construction codes under Utah Code Title 15A and enforces them through its own Building Inspection Division for unincorporated areas, with plan review, field inspections, and permit applications required through the county's online portal. There's no off-grid exemption noted, so any dwelling you build will go through the normal county permitting and inspection process. source

Septic & composting toilets

RestrictedSeptic systems in unincorporated Weber County are permitted through the Weber-Morgan Health Department, which has adopted the state's Underground Wastewater Systems Rule (R317-5) with its own local amendments, and requires a site and soil evaluation plus percolation testing before approval. Composting toilets aren't addressed as a distinct county allowance in the sources found, so confirm any composting-toilet plan with that same health department. source

Greywater reuse

RestrictedNo Weber County specific greywater ordinance turned up in the research, so the county appears to simply follow the state's greywater rule (R317-401), administered by the Weber-Morgan Health Department, the same office that handles septic. It's not confirmed whether that health department layers on any extra local standards, so ask them directly before installing a greywater system. source

Rainwater harvesting

Generally allowedNo Weber County ordinance was found that restricts or modifies Utah's statewide rainwater collection law (Utah Code 73-3-1.5), so the county appears to simply follow the state baseline allowing rainwater harvesting.

Private wells & water rights

RestrictedWell permitting for Weber County runs through the Weber-Morgan Health Department alongside septic permitting, on top of the standard state approval needed from the Utah Division of Water Rights for well construction. A neighboring county sharing this same health department confirms its dual septic/well role, though a Weber County-specific page stating this wasn't independently found, so it's worth confirming directly with the health department. source

Living disconnected from utilities

Unclear - verifyI couldn't find an official Weber County statement on whether an occupancy permit requires grid water, sewer, or electric hookups versus relying on an approved well and septic alone. The county's density rules do acknowledge lack of sanitary sewer or culinary water as a factor in lot-size calculations, which suggests off-grid setups are contemplated, but you'll want to ask Weber County Planning directly about occupancy requirements. source
