Off-Grid Living in Bingham County, Idaho
Bingham County has real zoning and building enforcement at the county level, but septic and well permitting are handled by the regional health district and the state, not the county itself. RVs can't serve as a primary dwelling, and a building permit requires proof of a septic solution even for otherwise off-grid homes.
Is it legal to live off-grid in Bingham County, Idaho?
There is no outright ban on living off-grid in Bingham County, Idaho - it is legal but regulated. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are generally allowed. Plan around septic/wastewater (generally allowed) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Bingham County before you buy land or build.

I've been digging into what it actually takes to live off-grid in Bingham County, Idaho, and the short version is: this isn't a "no rules" rural county. Bingham County has an adopted comprehensive plan and a real zoning ordinance (Title 10), enforced by the Bingham County Planning and Zoning Commission, so before you buy raw land here, check which zoning district it sits in and whether it's inside an incorporated city's "area of city impact" (Title 9), which can layer on extra rules.
On dwellings: county code is explicit that a "primary dwelling" can be a mobile or manufactured home, but an RV does not count as a permanent residence. Manufactured/mobile homes go through the Building Official for permitting and inspection under Title 8, and any structural modifications need sign-off from a State of Idaho certified engineer or architect. I could not confirm from any official county source whether a foundation-built tiny home (the kind built to IRC Appendix Q) would be accepted as a permanent residence here, so that's a direct question for Planning & Zoning before you build.
Building permits themselves are handled locally by the county's Building & Construction Division, which enforces state-adopted codes (Idaho Code Title 39, Chapter 43, and IDAPA 07.03.03) alongside county ordinance. Notably, the building permit checklist requires either a septic permit or a "will-serve letter" for sewage disposal before a permit is issued, meaning you can't get a building permit without a wastewater plan even if you're going off-grid for power and water.
Septic itself is not handled by the county at all, it's Southeastern Idaho Public Health, the regional health district, following state DEQ rules. Homeowners can self-install standard or basic alternative septic systems, which is good news for DIY-minded folks. Greywater isn't separately addressed; it falls under that same health district septic authority. Rainwater harvesting has no county ordinance I could find either way, so state water law through the Idaho Department of Water Resources (IDWR) is the default framework.
Wells are entirely state-administered: the county's own permit page just points residents straight to IDWR. There's no standalone "off-grid utilities" ban that I found, but the septic/will-serve requirement functionally forces a wastewater solution regardless of your electrical setup.
Bottom line: zoning and building are local (county), septic and wells are essentially state/regional programs the county defers to. Always confirm the specifics for your parcel directly with the offices below before you commit to land or a build plan.

Planning a build in Bingham County
The rules above decide what you may build. The numbers below decide what you will have to build, and they come from this place rather than from a national average.
Solar: size for the worst month, not the average
Bingham County averages 5.2 peak sun hours a day across the year, but its worst month averages 2.3. That is a drop of about 55 percent. An array sized on the annual figure will therefore come up short in the worst month by roughly that much, in the season when lights, pumps, and heating fans all run hardest.
Put another way, meeting the same daily load in the worst month here takes about 2.2 times the array that the annual average implies, or a generator and the fuel budget to run it. Neither is wrong; what is wrong is discovering the gap in the first winter. The solar calculator runs this arithmetic against your own load list, and lesson four covers building that list before buying panels.
Heat: 7,145 heating degree days
That is a genuinely cold heating season, where losing heat for a few days in winter risks the plumbing and the building itself. Heating demand at this level dwarfs everything electrical in the house, which is why almost nobody here heats with electricity from a battery bank.
As a rough order of magnitude, a small, reasonably insulated cabin heated mainly with wood in a climate like this tends to burn in the region of 6.0 cords a season, with the real figure swinging widely on insulation, house size, and how you burn. Treat that as a bracket for planning your woodshed rather than a promise, split and stack a season ahead, and check with a moisture meter before burning. The firewood calculator and heat-loss calculator narrow it down from your own building.
Water: what the roof would actually catch
Bingham County receives about 11.3 inches of precipitation a year. A 1,000 square foot roof here would shed on the order of 5,979 gallons a year at a realistic 85 percent collection efficiency, before any losses to first-flush diversion, evaporation, or overflow in a heavy storm.
The annual total is the easy part. What sizes a cistern is the longest dry stretch, because catchment is seasonal almost everywhere and a tank that covers the average year can still run empty in August. Check the local rules too: rainwater harvesting is regulated in some states even where it is broadly allowed. The rainwater calculator works from your own roof and rainfall pattern, and lesson three covers why water is chosen before power.
Distance is part of the plan
Measured straight line from the center of Bingham County: the nearest hospital is about 0.9 miles away (Bingham Memorial Hospital), the nearest supermarket is about 0.5 miles away (Kesler's). Road miles will be longer, and in winter longer again.
The hospital distance sets what your first aid kit and your medical plan have to cover in the gap, and it is the number to think about before anyone in the household depends on refrigerated medication or mains-powered equipment.
Confirming this for your own parcel
On this page 4 of the eight topics are recorded as unclear or as varying within Bingham County: zoning, greywater, rainwater harvesting, mandatory utility connection. Those are the calls to make first, because they are the ones where a general answer cannot be trusted for a specific parcel. Ask for the answer in writing where the office will give it, and note the name and the date where it will not.
Where a topic is recorded as settled here (what counts as a dwelling, building permits and codes, septic and sewage, wells and water rights), the source is cited further down this page. Sources go stale, ordinances get amended, and this site logs corrections publicly rather than editing them away, so if you find something here that no longer matches the county, the corrections page is how to say so.
Before any of those calls, walk the parcel with the land walk checklist and take the questions for the county with you. The parcel check pulls flood, wetland, slope, and access data for a specific parcel and shows its sources, which is a good way to arrive at the office with the questions already framed. Lesson two is the wider version of this list.

Not as a primary dwelling under county code, which specifically defines the primary dwelling as excluding RVs. Check with Bingham County Planning and Zoning about temporary occupancy rules while building.
Does Bingham County require me to hook up to septic before building a house?
The county's building permit checklist requires a septic permit or a will-serve letter before issuing a building permit, but septic itself is permitted through Southeastern Idaho Public Health, not the county directly.
Who do I call about drilling a well?
The county has no well ordinance of its own and points residents to the Idaho Department of Water Resources, which handles well permitting and water rights statewide.
Is rainwater harvesting regulated in Bingham County?
No county-specific rule was found for rainwater collection; it would fall under Idaho's general state water law framework administered by IDWR.
