Off-Grid Living in Deschutes County, Oregon

Deschutes County, Oregon is a place where off-grid living is genuinely possible, but it's not a legal free-for-all. I want to be upfront: this brief covers unincorporated county land only. If your parcel is inside Bend, Redmond, Sisters, or La Pine city limits, you're under different rules entirely and need to check with that city directly.

Zoning. Deschutes County has countywide zoning administered by its Community Development Department (CDD), so there's no "no zoning" loophole here. The rural residential zones where off-grid-style living is realistically pursued are MUA-10, RR-10, SR 2.5, UAR-10, and WTZ. Farm and forest resource zones are much more restrictive and generally limit new dwellings to farm/forest-related use under state exception rules. Which zone your land sits in matters a lot, and CDD can tell you.

Dwellings, tiny homes, RVs. The county opted into Oregon's SB 1013 program allowing RVs as rental dwellings in rural residential zones, but that program requires you already have a primary residence on the property, at least two acres (five in South County), and the RV within 100 feet of that primary dwelling, with sewage, water, and power provided to the pad. It is not a general right to live full-time in a standalone RV or tiny home as your only dwelling. Separately, the county permits rural Accessory Dwelling Units in these same zones. I did not find a standalone "tiny home" ordinance.

Building permits. The county issues permits under Oregon's adopted building codes. I found no evidence of a blanket off-grid exemption, so assume standard permitting applies to any habitable structure.

Septic. Where there's no public sewer, Deschutes County's Onsite Wastewater (Environmental Soils) Division, working under state DEQ rules, requires an approved septic system for any plumbing fixture. The county adds its own siting standards, including groundwater separation requirements, and in South County, DEQ works with the county to determine nitrogen-reducing treatment on a site-by-site basis. Composting toilet policy specifically wasn't confirmed, so ask the Onsite Wastewater office directly.

Greywater and rainwater. I couldn't confirm a county-specific rule for either. Both likely default to Oregon's statewide programs (DEQ for greywater, exemption from water-rights permitting for roof-catchment rainwater), but confirm with the county and DEQ before building a system.

Wells. Well construction is a state (OWRD) permitting matter, but Deschutes County sits inside the Deschutes Groundwater Mitigation Program area, meaning new permitted groundwater uses may require mitigation. Typical exempt domestic wells for a single home aren't subject to that mitigation process, but confirm your specific situation with OWRD.

Utilities. No blanket grid-hookup mandate was found, but the septic/building permit requirements above function as a practical constraint on any off-grid setup.
