Off-Grid Living in Yuma County, Colorado

I've been digging into what off-grid living actually looks like in Yuma County, Colorado, and the short version is: it's a rural, agriculture-first county that regulates land use through a countywide Land Use Code rather than a mapped zoning ordinance, and a lot of the heavy lifting (septic, wells) is delegated to other agencies. Here's what I found, dimension by dimension.

Zoning. Yuma County doesn't zone in the traditional sense. Instead, its Land Use Code requires a Land Use Permit for most "land use changes," and an Activity Notice for any building you put up, home, barn, garage, grain bin, you name it. The state's 35-acre subdivision threshold applies here too, but Yuma County has carved out its own exemption letting divisions creating 20 or fewer lots skip the subdivision process even if the lots are under 35 acres. Confirm your specific parcel with the county's Land Use Department before you plan anything.

Dwellings, tiny homes, RVs. The county's code specifically addresses older mobile homes (pre-1976) and multiple dwelling units on large parcels, but I could not confirm any specific rule on tiny-homes-on-wheels or RVs as full-time residences in unincorporated Yuma County. Ask the Land Use Department directly.

Building permits. I did not find evidence of a dedicated county building code department. New construction seems to run through the Land Use Office's Activity Notice process instead of a classic building-permit-and-inspection regime. Confirm code edition and inspection expectations with that office.

Septic. This one's clear: the Northeast Colorado Health Department (NCHD) issues Onsite Wastewater Treatment System (OWTS) permits for Yuma County under state Regulation 43. Landowners can self-install (one system per year) without a contractor license, subject to NCHD inspection. Composting toilets as a septic alternative are not specifically addressed, so I'd call NCHD before going that route.

Greywater and rainwater. I found no Yuma-County-specific programs for either. Both default to Colorado's statewide baseline, greywater reuse requires a county to opt into a CDPHE-consistent program (unconfirmed whether Yuma has), and rainwater collection is limited to the state's small-scale allowance tied to prior appropriation water rights.

Wells. State-permitted through the Colorado Division of Water Resources, and Yuma County layers on three active groundwater management districts (Sandhills, Arikaree Basin, and Central Yuma County) that a well applicant needs to coordinate with locally, on top of the state's exempt-well subdivision process.

Utilities. I found no county mandate forcing rural parcels to hook up to grid power or municipal water/sewer. Off-grid solar, wind, and hauled water look legally viable in unincorporated areas, though incorporated towns like Yuma, Wray, or Eckley may have their own municipal rules I haven't confirmed.

Bottom line: Yuma County is workable for off-grid living, but nearly every dimension routes through a different authority, county Land Use, NCHD for septic, and the state for wells, so plan on multiple phone calls before you break ground.
