Off-Grid Living in Wasco County, Oregon
Wasco County allows off-grid living, but zoning rules split between the standard county LUDO and a separate National Scenic Area LUDO depending on parcel location, and RVs/wheeled tiny homes are not permitted as permanent dwellings. Septic, wells, and building permits follow state programs (DEQ, OWRD, Oregon Building Codes Division) administered locally, so confirming which rules apply to your specific parcel with Wasco County Planning is the essential first step.
Is it legal to live off-grid in Wasco County, Oregon?
There is no outright ban on living off-grid in Wasco County, Oregon - it is legal but regulated. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are generally allowed. Plan around septic/wastewater (generally allowed) and disconnecting from utilities (generally allowed). Because these rules are set locally, confirm the specifics with Wasco County before you buy land or build.

I've been digging into what it actually takes to live off-grid in Wasco County, Oregon, and the short version is: it's doable, but you're dealing with two layers of rules that don't always overlap cleanly, plus a state agency backstop for building codes.
Zoning is countywide here, which isn't true everywhere in Oregon. The Wasco County Planning Division administers a Land Use and Development Ordinance (LUDO) built around the Oregon Statewide Planning Goals and the 1983 Comprehensive Plan. But if your land sits inside the Columbia River Gorge National Scenic Area, a separate NSA-LUDO and state/federal Gorge Management Plan rules apply instead. So step one, always, is figuring out which set of rules covers your specific parcel, and that's a Planning Division question, not a guess.
Dwellings: stick-built homes don't have county minimum size requirements as far as I could confirm, which is good news for small-footprint builds. RVs and tiny homes on a chassis, though, are classified and regulated as RVs, not permanent dwellings, according to county planning staff. If your off-grid plan involves a wheeled tiny home as a full-time residence, that's a real friction point worth calling Planning about before you commit.
Building permits run through a slightly unusual arrangement: the Oregon Building Codes Division (a state agency) actually administers the building code program for Wasco County directly, but Wasco County Planning still signs off on zoning and floodplain approval before that structural permit gets finalized. RV and manufactured home placements go through their own distinct permit track.
Septic: permitted, but administered through North Central Public Health District under Oregon DEQ's statewide onsite wastewater rules. An Environmental Health Specialist inspects and approves. I couldn't confirm any composting-toilet-specific county rule, so that's a call-and-ask situation.
Greywater and rainwater harvesting: I found no Wasco-specific rules for either, so they appear to follow Oregon's statewide DEQ baseline (for greywater) and state water-rights exemptions (for rainwater catchment), with local plumbing code potentially touching cistern setups.
Wells: state-regulated through Oregon Water Resources Department District 3, whose watermaster covers Wasco, Hood River, and Sherman counties. Worth flagging: local reporting suggests real groundwater decline concerns around Mosier, The Dalles, and Dufur, including a Critical Ground Water Area near The Dalles, so don't assume drilling a new well is a rubber stamp.
Utilities: nothing bans disconnecting from the grid outright, but you'll still need an approved wastewater solution to get building permits finalized.
Bottom line: no single office covers everything here, so plan on calls to both Planning and Building Codes, plus the health district for septic.

FAQ
Common questions about off-grid living in Wasco County
Is it legal to live off-grid in Wasco County, Oregon?
There is no outright ban on living off-grid in Wasco County, Oregon - it is legal but regulated. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are generally allowed. Plan around septic/wastewater (generally allowed) and disconnecting from utilities (generally allowed). Because these rules are set locally, confirm the specifics with Wasco County before you buy land or build.
Can I put a tiny house on wheels on my land in Wasco County and live in it full-time?
Based on county planning staff guidance, tiny homes on a chassis with an axle are classified as RVs in Wasco County and aren't permitted for permanent, full-time residency. Stick-built small homes don't appear to have a county minimum size requirement, so that's often a more workable route, but confirm both points directly with the Wasco County Planning Division.
Does living inside the Columbia River Gorge National Scenic Area change the rules?
Yes. Land inside the National Scenic Area is governed by a separate NSA-LUDO plus state and federal Gorge Management Plan rules, instead of the standard countywide LUDO. Check with Wasco County Planning to find out which set applies to your parcel.
Who actually issues my building permit, the county or the state?
The Oregon Building Codes Division, a state agency, administers the building permit program on behalf of Wasco County, but county Planning still has to sign off on zoning and floodplain approval as part of the process.
Are there special rules for composting toilets or greywater systems?
I could not confirm any Wasco County specific rules for composting toilets. Greywater appears to follow Oregon DEQ's statewide permitting tiers, administered locally by North Central Public Health District. Ask them directly for specifics.
Is it hard to get a well permit in Wasco County?
Well construction is regulated by the state through Oregon Water Resources Department District 3, but local reporting has flagged real groundwater decline concerns in parts of the county, including near The Dalles. It's worth checking current conditions with the OWRD watermaster before assuming a straightforward approval.
