Unincorporated Harney County, Oregon requires building permits for covered residential work, and the Harney County Planning Department administers the program1. County zoning governs only portions of the unincorporated area, and the cities of Burns and Hines run their own zoning23. Septic permits come from Harney County Onsite Sanitation under Oregon's DEQ program4.

Do you need a building permit in Harney County, Oregon?
Yes. Harney County requires a building permit to construct, enlarge, alter, repair or move a covered residential building or structure5. The statewide residential code covers construction, reconstruction and repair of one- and two-family dwellings and townhouses13. A narrow exemption may cover a detached, nonhabitable, one-story accessory structure under 200 square feet and under 15 feet from the floor to the average roof height, but separate electrical, plumbing or mechanical permits may still apply5. Qualifying agricultural buildings can be exempt from the structural specialty code, but that exemption does not cover a dwelling or erase electrical, plumbing and mechanical permit requirements14. Confirm the project category with the Harney County Building Program before ordering materials.
Who handles Harney County building permits and inspections?
The Harney County Planning Department administers building permits, while the county's Building Program is the practical starting point for applications and inspections1. Oregon places responsibility for obtaining necessary permits on the person doing the work, whether that person is a contractor or homeowner5. Online homeowner applications may be available through Oregon ePermitting, but participation is voluntary and each participating jurisdiction decides which permits it sells online15. Permit fees also depend on the work: Oregon's methods differ for structural, electrical, plumbing and mechanical permits, and local departmental fees may be added16. Once work begins, the permit holder must request required inspections and may not cover work or advance beyond an inspection point without approval17. Inside Burns and Hines, ask the city about zoning approval first3.
Does Harney County have zoning?
Yes, but Harney County's zoning ordinance governs only portions of the unincorporated area, and zoning inside the incorporated cities of Burns and Hines is set by those cities, not the county23. Septic permits, by contrast, stay with Harney County Onsite Sanitation18. In an R-1 zone, no new lot may be smaller than 5 acres or the size DEQ requires for septic approval, whichever is larger19. Farm-related land divisions use a 160-acre standard in EFRU-1 and an 80-acre standard in EFRU-2, while nonfarm divisions and statutory exceptions face additional review910. Dividing land or developing multiple residential lots also requires county subdivision or partition review20. District details matter: the R-1 zone generally requires a 20-foot property-line setback, while reviewed rural-center provisions require 20 feet from property lines and 100 feet from a stream or lake high-water line2122. The reviewed Rural Service Center–Andrews and materially repeated rural-center provisions cap all buildings at 60% of lot area; that percentage is not a countywide rule23. Land-use applications, including dwelling, partition, variance and conditional use requests, go on one consolidated county Land Use Permit Application24. Ask the Planning Department for the parcel's exact district, mapped overlays and applicable exceptions before laying out a house or splitting land.
How do septic permits work in Harney County?
Harney County Onsite Sanitation locally administers septic services under Oregon's DEQ onsite wastewater program418. A construction permit covers a new septic system as well as alterations or repairs, and an undeveloped site that has never received septic approval needs a site evaluation25. An affirmative Land Use Compatibility Statement is required before a construction permit for new construction or an alteration can issue25. Treat the evaluation as an early purchase contingency: only about 3% of Harney County soils are mapped without severe limitations for a conventional drain field26. Pressure-distribution, sand-filter and alternative-treatment systems have required inspection lists, although the onsite agent may waive certain inspections27. For property inside a city limit, urban growth boundary or sanitary district, Harney County states that new construction or repairs require signed Land Use Compatibility and Sewer Availability forms from January 1, 202628. Where public sewer is not legally and physically available, an onsite system still must meet usable-space, setback, capacity, soil and water-table requirements29. A composting toilet does not remove the need for approved handling of other household wastewater30.
Can you live in an RV or tiny home in Harney County?
In the portions of unincorporated Harney County governed by county zoning, an RV cannot serve as a permanent residential structure unless it is in a permitted RV park or receives land-use approval7. During construction of an approved dwelling, temporary RV occupancy requires written authorization from the Planning Director; occupancy beyond 30 days without that authorization is out of compliance7. Harney County does not issue building permits for an RV, and an RV may not be permanently connected to a septic system7. In the R-2 zone, a tiny home used as a dwelling is generally limited to 180 days or nights in a year and 180 consecutive days; an approved caretaker dwelling is excepted12. We could not confirm a countywide tiny-home rule or general minimum dwelling floor area; the ordinance's 8-by-32-foot minimum applies only to its defined pre-1962 residential-trailer category31. Ask the Planning Department to classify the unit and confirm the parcel's zone before buying.
What are the steps to build a home in Harney County?
- Ask the Harney County Planning Department to confirm the parcel's zoning designation, dwelling eligibility, setbacks and required land-use review322122.
- Secure a septic site evaluation and land-use compatibility approval through Harney County Onsite Sanitation before fixing the house location25.
- Resolve the water source; groundwater use and owner-performed well construction may require separate state applications, permits and bonding11.
- Submit residential plans and specialty-permit applications through the Harney County building program15.
- Request inspections at each permitted stage, and do not conceal work before approval17.
- Obtain the certificate of occupancy before living in a new dwelling unless the building official issues a temporary certificate33.
What should you check before buying land in Harney County?
Start with legal buildability, not acreage alone: confirm zoning, dwelling eligibility and the district's land-division rules with the Planning Department3220. Make septic feasibility a contract contingency because only about 3% of county soils are mapped without severe limits for a conventional drain field26. Verify water quantity and water rights independently; a landowner who personally constructs or alters a supply well can face a $550 permit fee, a $10,000 bond and a 6-month permit term11. Harney County averages about 12.6 inches of precipitation annually, and severe drought occurs in about 41.2% of years, so do not assume a parcel has dependable domestic or livestock water3435. Also check surveyed access and road jurisdiction: new connections to arterials and collectors are restricted near intersections36. In a mapped special flood hazard area, a county floodplain development permit is required before construction, and new homes must have the lowest floor one foot above base flood elevation where that elevation is available37. About 73.3% of the county is federal land, making legal access across neighboring ownership especially worth verifying38.
Watch-outs
- Harney County's owner-builder exemption is limited to specified structural-code subjects and does not eliminate the building permit8.
- In county-zoned unincorporated areas, an RV occupied during construction needs written authorization from the Planning Director, and an RV may not be permanently connected to a septic system7.
- A conditional use may exceed its zone's height limit up to 75 feet only by adding 5 feet to each required yard for every 5 feet or fraction of added height above 35 feet39.
