Off-Grid Living in Washakie County, Wyoming

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.
