Building permits, zoning and land rules 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 townhouses⁸. 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 requirements⁶. Confirm the project category with the Harney County Building Program before ordering materials.

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 online⁹. Permit fees also depend on the work: Oregon's methods differ for structural, electrical, plumbing and mechanical permits, and local departmental fees may be added¹⁰. Once work begins, the permit holder must request required inspections and may not cover work or advance beyond an inspection point without approval¹¹. Inside Burns and Hines, ask the city about zoning approval first³.

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 county^2,3. Septic permits, by contrast, stay with Harney County Onsite Sanitation¹². In an R-1 zone, no new lot may be smaller than 5 acres or the size DEQ requires for septic approval, whichever is larger². 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 review². Dividing land or developing multiple residential lots also requires county subdivision or partition review³. 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 line². 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 rule². Land-use applications, including dwelling, partition, variance and conditional use requests, go on one consolidated county Land Use Permit Application³. Ask the Planning Department for the parcel's exact district, mapped overlays and applicable exceptions before laying out a house or splitting land.

Harney County Onsite Sanitation locally administers septic services under Oregon's DEQ onsite wastewater program^4,12. 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 evaluation¹³. An affirmative Land Use Compatibility Statement is required before a construction permit for new construction or an alteration can issue¹³. Treat the evaluation as an early purchase contingency: only about 3% of Harney County soils are mapped without severe limitations for a conventional drain field¹⁴. Pressure-distribution, sand-filter and alternative-treatment systems have required inspection lists, although the onsite agent may waive certain inspections¹². 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, 2026¹². Where public sewer is not legally and physically available, an onsite system still must meet usable-space, setback, capacity, soil and water-table requirements¹³. A composting toilet does not remove the need for approved handling of other household wastewater¹⁵.

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 approval². 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 compliance². Harney County does not issue building permits for an RV, and an RV may not be permanently connected to a septic system². 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 excepted². 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 category². Ask the Planning Department to classify the unit and confirm the parcel's zone before buying.

1. Ask the Harney County Planning Department to confirm the parcel's zoning designation, dwelling eligibility, setbacks and required land-use review^2,3.

1. Secure a septic site evaluation and land-use compatibility approval through Harney County Onsite Sanitation before fixing the house location¹³.

1. Resolve the water source; groundwater use and owner-performed well construction may require separate state applications, permits and bonding⁷.

1. Submit residential plans and specialty-permit applications through the Harney County building program^1,5.

1. Request inspections at each permitted stage, and do not conceal work before approval¹¹.

1. Obtain the certificate of occupancy before living in a new dwelling unless the building official issues a temporary certificate¹¹.

Start with legal buildability, not acreage alone: confirm zoning, dwelling eligibility and the district's land-division rules with the Planning Department³. Make septic feasibility a contract contingency because only about 3% of county soils are mapped without severe limits for a conventional drain field¹⁴. 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 term⁷. 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 water¹⁴. Also check surveyed access and road jurisdiction: new connections to arterials and collectors are restricted near intersections². 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 available². About 73.3% of the county is federal land, making legal access across neighboring ownership especially worth verifying¹⁴.
