Barndominium Builders in Umatilla County, Oregon
Umatilla County covers about 3,200 square miles of wheat land, irrigated farms and Blue Mountain foothills, with twelve incorporated cities spread across it. Out here a barndominium is usually a working building first: a shop or equipment bay with the house under the same roofline, set on a farm, a grazing parcel or a rural residential lot. We design and build those, and we also supply barndominium kits for owners who want to put up the shell with their own crew. One thing is unusual about this county. There is no county building department; on most rural land the permit, plan review and inspections come from the state Building Codes Division's field office in Pendleton, and county planning clears the zoning first. The county's public health department handles septic. If your parcel sits near a city, check whether it falls inside that city's urban growth area, because Pendleton and Hermiston run their own planning rules there. A pole barn home is a natural fit on open ground where a clear span matters more than a narrow footprint. Tell us the tax lot through the survey, and we will check the zone, the flood map and the septic route before a plan is drawn; we can then take it through permitting and a turnkey build.

Pole Barn Homes near Umatilla County
A pole barn home sets its frame on posts and trusses (the engineering term is post-frame), which often suits a simple, wide layout with a shop bay under the same roof. Whether it fits your parcel comes down to the zoning and the site, set out below.
Permits, Zoning and Septic in Umatilla County
In Oregon the land-use answer often comes before the building answer. Here is who decides each part in Umatilla County, taken from the office or document that publishes it. Rules change, so check them again against your parcel before anything is drawn.
Oregon Building Codes Division, Pendleton field office
The Building Codes Division provides building department services for Umatilla County and several small cities, among them Athena, Milton-Freewater and Stanfield, with staff in its Pendleton field office handling plan review, permits and inspections. Plans are submitted after local planning and DEQ-program approvals. Cities with their own building departments, such as Hermiston, permit separately.

Umatilla County Planning Division (Community Development)
The county Planning Division handles zoning permits and land use requests for unincorporated land, and a pre-application meeting is required for land use requests. Most rural land is farm, grazing or forest zoning; a house there needs county approval under the state farm or forest dwelling tests before the state structural permit can be issued.

Umatilla County Public Health (UCO Health) onsite program, acting for DEQ
UCO Health, the county public health department, issues septic permits for homes not served by public sewer and inspects the systems it permits. It runs the local onsite program acting for DEQ, starting with a site evaluation packet that tests whether the parcel suits a new system.

- County zones for rural land
- The 2025 Umatilla County Development Code sets out Exclusive Farm Use, Grazing/Farm, Non-Resource, three Rural Residential zones (RR-2, RR-4 and RR-10), Multiple Use Forest, Forest Residential and Mountain Residential zones, among others (table of contents, read 26 September 2026).
- Floodplain development permit
- The county planning division says a County Floodplain Development Permit is required for properties within the flood hazard area. Its current Flood Insurance Study, effective 3 September 2010, brought the county and its incorporated cities onto one set of flood maps (read 26 September 2026).
- Land use sign-off before septic
- The Planning Division says a Land Use Compatibility Statement starts the review for a new septic system or a repair, and approval is also needed to reconnect to an existing system or to raise its waste flow by increasing the occupancy of a house or building (read 26 September 2026).

Building on land near Umatilla County
Check three maps before you buy. The zoning map comes first: on Exclusive Farm Use or Grazing/Farm land a house has to qualify under state tests, and a non-farm home can end the land's farm tax deferral, while the rural residential zones allow a home far more simply. The flood map comes next, since river bottoms along the Umatilla and its tributaries carry floodplain permits. Third, the soils: the septic site evaluation decides where the drainfield and replacement area go, which often fixes the house site. Water is the last check: a domestic well is normally exempt from a water right in Oregon, yet it still has to be drilled by a well constructor licensed by the state and logged with the Water Resources Department, and parts of this irrigated county have groundwater questions worth raising with that department early.
