Read this before you act on anything below. This is my researched starting point for Converse County, WY, 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 rulesConverse County, WY

Zoning & raw-land occupancy

Varies locallyConverse County's Planning & Zoning Commission regulates subdivision of land (4-acre minimum lot size in unincorporated areas) but this is not a general use-zoning code for existing parcels. Land within Douglas, Glenrock, Rolling Hills, or Lost Springs falls under that town's own zoning instead. source

Dwellings, tiny homes & RVs

Unclear - verifyConverse County is often described by outside sources as a 'no-code' county with few restrictions on tiny homes, mobile homes, or RVs as dwellings, but I could not confirm this on an official county document. Check the county's Permits & Regulations page or call directly before relying on it. source

Building permits & codes

Unclear - verifyThe county's official Permits & Regulations page is the right portal for building permit rules, but its specific content on countywide building codes was not confirmed in this research. Wyoming does require a state electrical permit for wiring work regardless of county. source

Septic & composting toilets

RestrictedWyoming DEQ runs the statewide small-wastewater permitting program under state statute, but in Converse County DEQ only handles commercial systems, so residential septic permitting is managed locally by the county. Contact the county to find the specific local office handling this. source

Greywater reuse

Generally allowedNo Converse County ordinance on greywater was found. Wyoming DEQ allows greywater reuse for irrigation or toilet flushing under a permit-by-rule mechanism statewide, and no county deviation was found. source

Rainwater harvesting

Generally allowedNo Converse County or Wyoming state prohibition on rainwater harvesting was found in this research.

Private wells & water rights

RestrictedWell construction is regulated by the Wyoming State Engineer's Office statewide, including Converse County. You must file an Application for Permit to Appropriate Ground Water before construction, and both drilling and pump installation must be done by state-licensed contractors. source

Living disconnected from utilities

Generally allowedNo Converse County ordinance requiring hookup to electric, gas, or municipal water/sewer was found for unincorporated land, so off-grid power setups appear permitted under the state baseline. Check any subdivision covenants specific to your parcel, since those can impose their own requirements. source
