Off-Grid Living in Linn County, Oregon

Linn County, Oregon runs its own countywide Planning & Building Department, so most of what governs off-grid living here is set at the county level, layered on top of Oregon state statutes and administrative rules. I want to be upfront: I'm a researcher, not a lawyer, and I haven't built anything here myself. Confirm details with the offices below before you buy land or break ground.

Zoning. Linn County has countywide zoning, not a patchwork of city rules, administered by the Planning & Building Department. There are Rural Residential zones (RR-1, RR-2½, RR-5, RR-10) plus Farm/Forest and Rural Resource zones, each with its own dwelling rules. Simply parking on raw land and living there isn't a separate legal category, you have to go through whatever dwelling-approval path applies to your specific zone.

Dwellings, tiny homes, RVs. The county's own permit forms treat RVs and mobile/manufactured homes as restricted, temporary-use categories. There's a Temporary Storage of Mobile Home form, a Temporary Use of a Recreational Vehicle form, and a Temporary Hardship Permit, which tells me full-time RV or mobile-home living isn't allowed outright, it needs a specific approval. Whether Linn County has opted into Oregon's SB 1013 program allowing RVs as rental dwellings isn't confirmed, so ask Planning & Building directly.

Building permits. Required, issued by Linn County under state code (Oregon's Epermitting/BuildingPermits.Oregon.gov system). Locally, the county's own checklist makes clear that sanitation (septic) and site plan approvals must happen before a building permit can be issued, so start with a sanitarian early to avoid delays.

Septic and composting toilets. Linn County Environmental Health issues septic site approvals, permits, and inspections, under Oregon's statewide OAR 340-71/340-73 rules. Anyone other than the property owner doing the install must be DEQ-licensed and bonded. Composting toilets as a stand-alone system (no septic) aren't addressed on the county's pages I found, so treat that as unconfirmed and ask Environmental Health.

Greywater. No Linn County-specific greywater page turned up. This likely defers to Oregon DEQ's statewide tiered greywater permit program, administered locally through the same Environmental Health septic office, but that's not confirmed.

Rainwater. No county restriction found on rooftop collection; Oregon's general state exemption for rooftop catchment likely applies, though any county-specific plumbing code wrinkles are not confirmed.

Wells. Private domestic wells are regulated at the state level by the Oregon Water Resources Department, with well construction overseen by the District 2 Watermaster covering Linn and Lane counties. The county Health Department's drinking water role only covers public water systems (restaurants, campgrounds, subdivisions), not individual private wells.

Off-grid utilities generally. Living without grid power or municipal hookups isn't banned by Linn County, but a legal dwelling still needs an approved septic system and water source before a building permit is issued, so "no utilities" doesn't mean "no permits."
