Off-Grid Living in Jackson County, Oregon

Jackson County, Oregon is one of the more workable places in the state for off-grid-minded living, mostly because it has real countywide zoning and a dedicated local Watermaster, but it's not a free-for-all. Here's what I found researching the county's own pages plus state sources.

Zoning is administered by Jackson County itself through its Land Development Ordinance, not just deference to state minimums. Rural Residential (RR-5) zoning, for example, sets a 5-acre minimum for new parcels, and density runs one dwelling per that minimum (so a 10-acre RR-5 parcel could support two dwellings). Farm and forest resource zones are tighter, with dwelling siting governed by state law as implemented in the county's LDO. Always check your specific parcel's zone with the county Planning Division before assuming what you can build.

Dwellings, tiny homes, and RVs: The county's Building Division handles Oregon's structural, mechanical, plumbing, electrical, and manufactured-dwelling codes, and any dwelling needs a permit. A guest house or accessory unit counts as a second dwelling for zoning purposes, so your lot needs to be large enough under the zone's rules. I could not confirm whether Jackson County has opted into Oregon's SB 1013 program allowing RVs as permanent rental dwellings, so ask Development Services directly if that's your plan.

Building permits are required for constructing, enlarging, altering, or moving one- or two-family dwellings, administered locally by the county's Building Division under state code. Contact Development Services before you start any project.

Septic: here's a real quirk. Unlike most Oregon counties, Jackson County residents apply directly to the state DEQ (Medford office) for septic permits and inspections, not to a county health department. Composting toilets fall under that same DEQ onsite wastewater framework; there's no separate county ordinance I could find.

Greywater and rainwater both appear to inherit the state baseline. I found no Jackson County-specific ordinance for either. It's reasonable to guess DEQ handles greywater permitting locally since it already handles septic here, but that's not confirmed at the county level. Rooftop rainwater collection is generally allowed under Oregon's state exemption, with no added county restriction found.

Wells and water rights: Jackson County actually has its own OWRD field office, the District 13 Watermaster, that handles well inspections and water-rights questions locally, in cooperation with the county. Domestic wells still need a water-use exemption under Oregon law since all water is publicly owned. The county's Health & Human Services department also recommends private well owners test for bacteria a few times a year and nitrates annually, since there's no mandated water-quality monitoring for the roughly 30,000 residential wells in the county.

Living off-grid/disconnected from utilities: I found no outright countywide ban. The practical gatekeepers are the building permit process and DEQ's septic authorization, both of which typically expect an approved water source and wastewater plan before occupancy is signed off.
