Off-Grid Living in Washakie County, Wyoming
Washakie County, Wyoming has a light zoning framework but no countywide building code and no delegated septic permitting, so several off-grid rules default straight to the State of Wyoming or DEQ rather than the county. Confirm zoning with the county Planner, septic with DEQ, and wells with the State Engineer before you build.
Is it legal to live off-grid in Washakie County, Wyoming?
There is no outright ban on living off-grid in Washakie County, Wyoming - it is generally possible. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is generally allowed, and building permits are not clearly documented online, so confirm it locally. Plan around septic/wastewater (restricted) and disconnecting from utilities (set locally and vary by area). Because these rules are set locally, confirm the specifics with Washakie County before you buy land or build.

If you're eyeing raw land in Washakie County, Wyoming for an off-grid setup, here's what my research turned up. The short version: this is a lightly regulated county, but "lightly regulated" doesn't mean "unregulated," and some of what you'd expect the county to handle actually falls back to the State of Wyoming or to DEQ instead.
Zoning and land use run through the Washakie County Planner's office, which administers the county's Subdivision and Development Regulation. That said, a Wyoming County Commissioners Association survey lists Washakie as having no countywide building program, so the zoning picture for unincorporated land is more of a light framework than a comprehensive code. I'd call the Planner directly before you buy or build.
Dwellings, tiny homes, and RVs appear to be permitted with minimal regulation in unincorporated parts of the county, based on the Planner and Assessor's offices confirming that permits route through Planning & Zoning. I didn't find a county source specifically addressing tiny homes, so confirm your plans with the county. If you're inside Worland or Ten Sleep town limits, those towns may have their own residential codes layered on top.
Building permits and codes: Washakie County itself hasn't adopted a countywide building code. Under Wyoming law, that generally means the State Fire Marshal holds default enforcement authority for fire, building, and electrical safety where local governments haven't taken it over. I haven't independently verified the State Fire Marshal's current role here this session, so confirm directly.
Septic systems are the trickiest part. Washakie is not one of the counties DEQ lists as having delegated small-wastewater permitting authority (that list includes Campbell, Carbon, Niobrara, Platte, and Weston). So septic permitting for Washakie likely runs through the DEQ District Engineer under statewide Water Quality Rules, not the county. Confirm the exact permitting path with DEQ or the county before installing anything.
Greywater and rainwater harvesting: I found no county-specific rules on either, so these appear to default to the state baseline, which doesn't restrict typical residential rainwater collection or greywater reuse under DEQ's general framework.
Private wells are entirely a state matter. Wyoming has required a State Engineer permit for groundwater wells, including stock and domestic wells, since 1969. The county's role is limited to recording the well at the Clerk's office alongside the State Engineer's filing. Local aquifer yields vary quite a bit depending on formation, so a local well driller's input is worth getting.
Living off-grid without utility hookups doesn't appear to be prohibited by any county ordinance I could find. Wyoming statute waives the licensed-electrician requirement for owner-installed wiring on your own property (not for resale), though a state electrical permit is generally still required.
Bottom line: Washakie County keeps its own footprint small, but that pushes more of the real authority to the State of Wyoming, especially for wells, septic, and electrical work. Call before you build.

Planning a build in Washakie 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
Washakie County averages 5.5 peak sun hours a day across the year, but its worst month averages 3.8. That is a drop of about 32 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 1.5 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: 8,449 heating degree days
That is a severe heating season, where the building envelope matters more than any appliance you can buy. 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 7.0 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
Washakie County receives about 11.2 inches of precipitation a year. A 1,000 square foot roof here would shed on the order of 5,910 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 Washakie County: the nearest fire station is about 3.0 miles away (Fort Washakie Fire Station), the nearest hospital is about 17.0 miles away (SageWest Health Care - Lander), the nearest supermarket is about 3.7 miles away (Hines General Store). Road miles will be longer, and in winter longer again.
The fire distance is worth noting before you buy rather than at renewal: insurers commonly rate rural property partly on how far it is from a responding station and from a water source, and some decline off-grid or owner-built structures outright. Ask an agent who writes rural policies what they would need to see, while the answer can still change what you build. Lesson eleven covers the insurance and financing side.
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 3 of the eight topics are recorded as unclear or as varying within Washakie County: zoning, building permits and codes, 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, septic and sewage, greywater, rainwater harvesting, 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.

FAQ
Common questions about off-grid living in Washakie County
Is it legal to live off-grid in Washakie County, Wyoming?
There is no outright ban on living off-grid in Washakie County, Wyoming - it is generally possible. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is generally allowed, and building permits are not clearly documented online, so confirm it locally. Plan around septic/wastewater (restricted) and disconnecting from utilities (set locally and vary by area). Because these rules are set locally, confirm the specifics with Washakie County before you buy land or build.
Does Washakie County have its own building code?
No. Research indicates the county has not adopted a countywide building code, which generally means the Wyoming State Fire Marshal holds default enforcement authority for building, fire, and electrical safety where local governments haven't taken it over. Confirm directly with the State Fire Marshal's office.
Can I install a septic system on my own in Washakie County?
You'll need a permit, but Washakie isn't listed among the counties DEQ has delegated septic permitting authority to, so the permit likely comes from the DEQ District Engineer rather than the county. Check with DEQ or the county before you dig.
Do I need a permit to drill a well?
Yes. Wyoming has required a State Engineer permit for all groundwater wells, including domestic and stock wells, since 1969. The county Clerk's office also records the well filing.
Are tiny homes and RVs allowed as permanent residences in unincorporated Washakie County?
It appears so, with minimal regulation, based on the county Planner and Assessor's offices, though this isn't confirmed by a source specific to tiny homes. If you're inside Worland or Ten Sleep town limits, check the town's own code.
