Barndominium kits, pole barn homes and turnkey builds in Oregon

Nine ways to get a barndominium out of your head and onto your land in Oregon, from a barndominium kit you put up yourself to a finished pole barn or steel home we hand you the keys to.

Barndominium Kits

Barndominium kits and shell kits for Oregon land, sized to the snow, wind and seismic values the state's design hub gives for your exact site.

Custom Plans

Custom barndominium plans drawn for Oregon's residential code, your site's snow and seismic values, and the energy chapter a steel shell must meet.

Pole Barn Homes

Pole barn homes and pole barn home kits for Oregon land, built as dwellings under the state residential code, not as farm buildings.

Shouses

Shop houses in Oregon: a working shop and a home under one roof, planned around your zoning, septic and the residential code from the first sketch.

Metal Homes

Metal building homes in Oregon, finished as real houses: insulated to the state energy chapter, detailed for wet winters, and hardened for wildfire.

Steel Construction

Red-iron steel frames and metal building shells erected across Oregon, sized to your site's snow, wind and seismic values and built to live in.

Turnkey Builds

Turnkey barndominiums in Oregon, from the land-use question on raw land to the final inspection, and the order every approval has to come in.

Site Preparation

Barndominium site preparation in Oregon: the land-use check, septic site evaluation and well location first, then clearing, drive, pad and drainage.

Permitting & Approvals

Barndominium permits in Oregon, in the right order: county land-use approval, the DEQ septic evaluation, then the building permit under the state code.

Barndominium floor plans

Start from one of our barndominium floor plans and change it, or have a plan drawn from scratch around your land, your shop and the way you live. Either way the plan is fitted to the parcel: where the septic and well can go, which way the lot drains, and what the county setbacks allow.

Cost guide

How much does it cost to build a barndominium in Oregon?

We do not publish a price list, because on an Oregon barndominium the land moves the number more than the floor plan does: the driveway, the pad, how far power has to run, a well and a septic system, and what the planning and building offices ask for. The cost guide sets out published third-party cost data, every figure with its source, and walks through what pushes a build to the top or bottom of the range.

How a build runs

Land to keys, in four stages

In Oregon, barndominium projects go wrong early, at zoning, septic and site checks, long before anyone pours concrete. Here is the order we work in and why.

Start your plans

Start the survey. We take your program, the rooms, the shop bay, how you actually want to live in it, and start a floor plan drawn for your land rather than pulled off a shelf, whether you bring a sketch, a saved layout or a blank sheet. This is where most of the useful decisions get made.

That is how a build runs. Step one is a plan drawn for your land, and that starts with the survey.

Start the survey

Building a barndominium in Oregon

Four things shape an Oregon build before anyone pours concrete, and the first of them is whether the land allows a home at all.

Land use comes first

In Oregon the first question is not the floor plan but whether the parcel allows a house at all. Inside an urban growth boundary land is planned for urban use; outside it, county zoning (farm, forest or rural residential) decides whether a house is allowed, and most exclusive farm use land only allows a dwelling that qualifies under state tests. We check the zoning with the county planning department before anything is designed.

Are barndominiums legal in Oregon?

One statewide code

Oregon homes are built to the Oregon Residential Specialty Code, one statewide code that cities and counties may not change on their own. Inside city limits the city building department issues the permit; in most unincorporated areas it is the county. The state Local Building Department Directory shows which office serves your address, and we draw the plans to what that office will review.

How we handle permitting

Wet west, snowy and dry east

West of the Cascades a build is planned around rain: drainage, the pad, moisture control and how the envelope sheds water. East of them it is snow, cold and wildfire exposure. There is no single Oregon snow or wind figure: the Building Codes Division publishes snow, wind, seismic and frost-depth values for each site through its Oregon Design Criteria Hub, and the frame is sized to the values for yours.

Pole barn homes

Septic and well on rural land

Off city sewer and water, the parcel needs a septic system and usually a well. A septic system needs a site evaluation and a permit from the Department of Environmental Quality or the county acting for it. A household well can usually be drilled without a water right, but it must be built by a licensed well constructor and recorded with the Water Resources Department. We check both early, because the septic site evaluation can decide where the house goes.

Barndominium builders across Oregon

Looking for barndominium builders near you? We build in seven regions of Oregon, from the Willamette Valley and the Rogue Valley to Central Oregon, the coast and the east side. Inside the cities most land is already built out, so most of our work is on rural and edge-of-town parcels in the counties around them. Zoning, building permits and septic approvals sit with different offices from one county to the next, so every project starts with the parcel.

Building in Oregon: common questions

16 questions we get asked most often about building in Oregon. If yours is not on the list, ask it directly.

Start the survey
Do you build barndominiums across Oregon?
Yes. Oregon Barndominium Builders builds barndominiums, pole barn homes and metal building homes on private land across Oregon: Portland, Gresham, Hillsboro, Beaverton and Oregon City in the Portland metro; Salem, Albany, Corvallis, Lebanon and McMinnville in the mid-Willamette Valley; Eugene and Springfield in Lane County; Bend, Redmond and Prineville in Central Oregon; Medford, Grants Pass, Ashland, Roseburg and Klamath Falls in Southern Oregon; Coos Bay, Astoria and Lincoln County on the coast; and Hood River, The Dalles, Pendleton, Hermiston and La Grande in the Columbia Gorge and Eastern Oregon. See the areas we serve, or start the survey with your parcel.
Do you build on land I already own?
Yes, and that is most of the work: rural acreage, family land and edge-of-town lots. We check what the zoning allows, walk the property with you, check access for concrete trucks and delivery equipment, and work out where power, water and a septic system can go. If you have not bought land yet, look at the zoning with us before you close on it: in Oregon, whether a parcel allows a new home is a question to answer before the purchase, not after. Tell us where it is in the survey.
Do you sell barndominium kits in Oregon, or only full builds?
Both. You can buy a barndominium kit and put it up yourself or with your own crew, buy a dried-in shell and finish the inside yourself, or hand us the whole project from bare land to keys as a turnkey build. Oregon lets owners build on their own property without a contractor licence, which is what makes a kit a real option; plumbing, electrical and HVAC still go to licensed trade contractors. Most people know which fits once they have looked honestly at their time, their budget and who they have available to build. Tell us which way you are leaning in the survey.
What is the difference between a barndominium, a pole barn home and a metal building home?
Barndominium describes what the building is: a home, usually open-plan and often with a shop or garage bay under the same roof. A pole barn home is built on a wood frame of large posts, spaced wide apart, that carry the roof and wall loads, with girts and purlins running between them. A metal building home is framed in steel instead. Inside, any of them is finished like a conventional house. We build both pole barn and steel-frame barndominiums.
How much does it cost to build a barndominium in Oregon?
We do not publish a price list, because on a barndominium the land moves the number more than the floor plan does: the driveway, the pad, how far power has to run, whether the parcel needs a well and a septic system, and what the county and building department ask for. Our barndominium cost guide sets out published third-party cost data with its sources. One Oregon difference: the state has no general sales tax, so kit materials bought in Oregon carry no sales tax, though some building permits include a construction excise tax. For a number against your own parcel, start the survey and we will put a written quote in front of you before anything is ordered.
Is a barndominium cheaper to build than a traditional house?
Sometimes, but not automatically. A pole barn or metal building shell spans wide without interior load-bearing walls, but a barndominium is finished inside like any house, and insulation, drywall, cabinets, flooring, plumbing, electrical and HVAC cost much the same whatever frame they sit in. The land work (driveway, pad, power, well and septic) often decides the comparison. Our barndominium vs. house cost guide sets the two side by side with cited data.
What is included in a barndominium kit, and what does it leave out?
A kit is typically the structural shell: the frame, roof and wall panels, trim and fasteners, and the doors the package names. The slab, site work, delivery and erection, insulation, and the whole interior finish usually sit outside it, so the kit price is only part of what the finished home costs. Ask exactly what a kit quote covers before comparing two. Our barndominium kits page and the cost guide walk through the line items.
Can I build a barndominium on farm or forest land in Oregon?
Sometimes, and it is the first thing to check. In Oregon, whether you can put a house on farm or forest land is decided by county land-use rules before any building permit. Most exclusive farm use (EFU) land only allows a dwelling that qualifies under state tests (ORS 215.203, 215.283, 215.284), forest zones allow a dwelling only where the parcel passes tests set in state law (ORS 215.750), and building a non-farm home on farm-deferred land ends the deferral and can bring up to ten years of back taxes (ORS 308A.113, 308A.703). An existing barn or shop cannot simply be lived in: a dwelling needs its own land-use approval and residential permit. Inside an urban growth boundary land is planned for urban use; outside it, county zoning (farm, forest or rural residential) decides whether a house is allowed. Check the zoning with the county planning department before you buy. Are barndominiums legal in Oregon? covers the detail.
Do I need a building permit for a barndominium in Oregon?
Yes. A barndominium is a dwelling, so Oregon's agricultural-building exemption does not apply to it (ORS 455.315), and it is built to the Oregon Residential Specialty Code (ORSC), one statewide code that cities and counties may not change on their own (ORS 455.040). The current ORSC (2023) is based on the 2021 International Residential Code; the state expects a 2026 edition based on the 2024 IRC from October 2026 (Oregon Administrative Rules, chapter 918, division 480). Inside city limits the city building department issues the permit; in most unincorporated areas it is the county, and the state Local Building Department Directory shows which office serves your address. Before that, the county planning department confirms the zoning allows the house, and a septic system needs its own permit. We handle that sequence as part of permitting.
Who approves the septic system and the well?
A septic system needs a site evaluation and a permit from the Oregon Department of Environmental Quality (DEQ) or the county acting for DEQ (ORS 454.655, 454.725); in Jackson and Josephine counties that is DEQ's Medford office. A household well can usually be drilled without a water right, because Oregon exempts domestic use up to 15,000 gallons a day (ORS 537.545), but it must be built by a licensed well constructor and recorded with the Water Resources Department. We do not design or install septic systems or drill wells. Both are checked early, because the septic site evaluation can decide where the house goes. See site preparation.
Can you plan a barndominium for Oregon rain, snow and wildfire country?
Yes, and it depends which side of the Cascades you are on. West of them the design conversation is about rain: drainage, the height of the pad, moisture control and how the envelope sheds water. East of them it is snow, cold and wildfire exposure: roof pitch, and the materials and clearances around the house. There is no single Oregon snow or wind figure: snow, wind, seismic and frost-depth design values are set for each site, and the Building Codes Division publishes them in its Oregon Design Criteria Hub. Oregon's statewide wildfire hazard map was repealed in 2025, and the wildfire construction standards in the residential code (section R327) apply only where your city or county has adopted them.
Can you build a shop house, with living space and a shop under one roof?
Yes. A shop house, or shouse, puts a working shop or equipment bay and the living space under one roof, and it is one of the most common reasons people choose a barndominium. The shop door size, the ceiling height in the bay and how the living space is separated from it are the decisions that shape the plan. If you might add a bay or a wing later, say so at the start: sizing the slab, leaving a gable end clear and running enough electrical capacity now makes that far simpler.
Can I finance a barndominium like a normal house?
Often, but not with every lender. Some treat a barndominium as ordinary residential construction; others are less familiar with it, and the appraisal is where that tends to show. We can provide the plans, specifications and cost breakdown a lender asks for during approval and the construction draw process. Our barndominium financing guide walks through the options.
Do I need an architect to draw barndominium plans in Oregon?
Not for a single-family home. Oregon law lets someone who is not an architect prepare the drawings for a single-family residential dwelling or a farm building (ORS 671.030(2)(b)), so the plan set for your custom plans is drawn by our design team. The structural design of a steel or pole barn frame comes from the frame manufacturer's registered professional engineer.
Who handles plumbing, electrical and HVAC?
Licensed trade contractors handle plumbing, electrical and HVAC. On a turnkey build we schedule that work as part of the project, so you deal with one point of contact from the first drawing to the final walkthrough rather than a chain of separate contractors.
How do I get started?
Start the survey. It asks where the land is, what you want to build, roughly how big, how you want to buy it (kit, shell or turnkey) and when. That is enough for us to come back with the questions that matter for your parcel, starting with what its zoning allows. There is no charge for that conversation.
