Off-Grid Living in Douglas County, Oregon

Douglas County, Oregon is one of the more manageable places to try off-grid living in the state, but "off-grid" here doesn't mean "off the radar." The county has full countywide zoning through its Land Use and Development Ordinance (LUDO), a county Building Department, and its own onsite wastewater (septic) permitting shop running under a DEQ contract. That's actually a plus for research purposes, since it means you're dealing with one consistent county authority for most things rather than being bounced between DEQ regional offices.

Zoning and raw land. Douglas County has had zoning since 1960 and subdivision rules since 1955, both required by Oregon state statute. The LUDO breaks the county into zones (forest, farm, rural residential, etc.), each with its own minimum parcel size and allowed uses. I can't give you a single countywide acreage minimum here, it varies chapter by chapter, so pull your specific tax lot's zone from the Planning Department before you buy or build.

Dwellings, tiny homes, RVs. This is where Douglas County gets stricter than some rural counties. If you park an RV and live in it 90 days or more in a calendar year, the county treats it like a manufactured home, subject to the same land use and building code rules. There are hardship-dwelling and mining-claim exceptions, but those are narrow. Manufactured dwellings need to meet the statewide building code plus planning and building department sign-off. I couldn't confirm specific tiny-home (site-built vs. park model) or ADU rules from an official county source, so ask Planning directly.

Building permits. The county Building Division issues and inspects all permits for unincorporated Douglas County, and requires registered contractors. Fees follow the state's Oregon Building Codes Division fee schedule plus a state surcharge, I'm not going to guess at numbers, check with the Division. Some incorporated towns, like Drain, actually contract with the county for this rather than running their own building department.

Septic. DEQ owns the statewide onsite wastewater program, but in Douglas County (as in 33 of Oregon's 36 counties) that authority is delegated to the county's own Onsite Services office within Planning. You'll need a site evaluation by a county sanitarian before you can get a construction-installation permit. Composting toilets aren't addressed specifically at the county level as far as I found, state OAR rules likely apply, but confirm with Onsite Services.

Greywater and rainwater. No county-specific rules turned up for either. Both appear to fall under Oregon's standard state programs (DEQ's tiered greywater permits, and building/plumbing code for rainwater catchment) without additional county layers.

Wells. No separate county well ordinance found. The state's Water Resources Department handles well construction and water rights; the county's building permit process just puts the burden on you to locate and disclose existing wells and utilities before you dig or build.

Off-grid living generally. You can live disconnected from municipal utilities, but your building permit application will still need an approved wastewater method signed off by the county's Onsite Services office before it's finalized. That's the real gatekeeper here more than any grid-connection rule.
