Read this before you act on anything below. This is my researched starting point for Klamath County, OR, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesKlamath County, OR

Zoning & raw-land occupancy
RestrictedKlamath County Planning Division administers countywide zoning through its Land Development Code; in Rural Residential zones a dwelling is the primary use and most other structures are accessory, except one 100 sq ft non-habitable building like a pump house. This is a county rule, not a state one. source
Dwellings, tiny homes & RVs
RestrictedThe county requires dwellings to meet the Oregon Residential Specialty Code, with the smallest compliant home around 300 sq ft per the county's FAQ; living in an RV long-term is treated as camping (21 days per 6 months) unless you hold a Temporary Use Permit tied to an active dwelling building permit. source
Building permits & codes
RestrictedKlamath County's Building Division enforces Oregon's statewide building, energy, and safety codes, and adds flood-plain elevation requirements verified by the Planning Department where applicable. source
Septic & composting toilets
RestrictedAll wastewater-producing fixtures must connect to an approved septic system per county Onsite rules and Oregon DEQ standards, starting with a site evaluation; whether composting toilets alone satisfy the county is not confirmed, so ask the Onsite office directly. source
Greywater reuse
Unclear - verifyNo county-specific greywater ordinance was found; the county's onsite wastewater rules seem to fold greywater into the standard septic-connection requirement, but whether the county processes Oregon DEQ's separate greywater permit tier locally is not confirmed, ask the Onsite office.
Rainwater harvesting
Unclear - verifyNo Klamath County ordinance on rooftop rainwater collection was found in official sources; not confirmed whether county building or plumbing code adds any permitting for household-use storage tanks.
Private wells & water rights
RestrictedNew domestic wells must meet Oregon Water Resources Department (state) construction standards, and the Klamath Falls OWRD Watermaster's Office oversees local regulation amid significant, well-documented groundwater decline in the basin. source
Living disconnected from utilities
RestrictedKlamath County allows off-grid living in principle but funnels everyone through the standard dwelling and building-permit process; there is no separate exemption for a small off-grid cabin, and unpermitted bare-land living is treated as camping. source
