Barndominium Builders in Lebanon, Oregon

Lebanon, Oregon is a South Santiam River town in Linn County, ringed by the grass-seed fields of the valley floor to the west and the Cascade foothills rising to the east. That mix is why people ask us about barndominiums here: a family can find a town lot with room for a shop, or look just outside the limits for acreage. Inside the city, Lebanon's own Building Division handles the structural, plumbing and mechanical permits and the inspections, and the Lebanon Development Code decides what a lot allows. Land in the urban growth area that has not been annexed is a different story: it still sits under Linn County's jurisdiction and county zoning until the city annexes it. Our barndominium kits give an owner-builder the steel or pole frame, the roof and the wall package to raise with their own crew, while a turnkey build covers the project from site work to final inspection. For open country beyond the growth boundary, the Linn County page explains the farm and forest zones and who approves a home there. Tell us where the parcel is and what you want under the roof, and we will check the zone, the creek setbacks and the slope first.

Barndominium Kits and Plans for Lebanon

The parcel decides the budget more than the floor area does, so each option is priced against your land rather than a rate card.

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 near Lebanon

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 Lebanon

In Oregon the land-use answer often comes before the building answer. Here is who decides each part in Lebanon, taken from the office or document that publishes it. Rules change, so check them again against your parcel before anything is drawn.

Who issues the building permitCity building program

City of Lebanon Building Division (Development Services Department)

Lebanon's Building Division issues all building, mechanical and plumbing permits in the city and does the plan reviews and inspections for residential projects, including manufactured home placements. Electrical permits inside the city limits come from Linn County, not the city. Unannexed land around Lebanon is permitted through the county.

Who decides the land useInside an urban growth boundary

City of Lebanon Planning Division (Lebanon Development Code); Linn County for unannexed land

Before annexation, land inside Lebanon's urban growth boundary (the code calls it the Urban Growth Area) carries a city Comprehensive Plan designation but remains under Linn County's jurisdiction with a county zone. Annexation transfers jurisdiction to the city and assigns the matching city zone; annexed land cannot keep its county designation.

Sewer or septicPublic sewer

City of Lebanon (sanitary sewer facility plan, Development Code Chapter 16.16)

Lebanon's code requires adequate sanitary sewer and water service to be made available to each new development, built to the city's sewer and water facility plans, and says no development may occur unless required public or private facilities are in place or guaranteed.

River and creek setbacks: Lebanon's Riparian Protection Overlay Zone applies along the South Santiam River, Oak Creek and Cheadle Lake, measured upland from top of bank: 75 feet on the South Santiam and 50 feet on Oak Creek and Cheadle Lake (Development Code Chapter 16.11).
Steep slopes and floodplain overlays: The same chapter sets a Steep Slope Development Overlay for slopes of 15 percent or more, to limit earth movement and erosion, and a Flood Plain Overlay Zone for special flood hazard areas. Where an overlay and the base zone conflict, the more restrictive standard applies.
Grass seed country around town: Linn County's Land Use Element (revised 15 April 2025) says grass seed is the county's primary crop and that nearly 25 percent of county land is designated Agricultural Resource, with forest resource land dominating the Cascade foothills to the east.

Building on land near Lebanon

Walk the creek lines before you choose a building spot. Along the South Santiam, Oak Creek and Cheadle Lake a riparian buffer keeps the house and shop well back from the bank, and parts of town sit in the mapped flood hazard area as well. East toward the foothills, slopes of 15 percent or steeper bring extra review for grading and erosion. If the lot is in the growth area but not yet annexed, the county still zones it, so city services and city zoning are not automatic. Beyond the boundary, the surrounding farm ground is mostly zoned for agriculture, and a new home there needs county land-use approval first. Our site preparation crew can plan the pad and drainage once the zoning is settled.

Building in Lebanon: questions

Start the survey

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

It depends heavily on the parcel. A town lot with sewer at the street costs less to prepare than a rural site that needs a well, a septic system and a long gravel drive, and a sloped or creekside lot adds grading and setback work. The shell itself varies with span, height and finish level. For published cost ranges and what drives them, see the barndominium cost guide.

Do I need a building permit for a barndominium in Lebanon?

Yes. Inside the city limits the Lebanon Building Division issues the building, plumbing and mechanical permits and inspects the work, while the electrical permit comes from Linn County. A barndominium used as a home is a dwelling and is permitted as one. Land that is still unannexed is handled by the county instead.

Can I build a pole barn home on land just outside Lebanon?

Possibly, but zoning decides first. Unannexed land in the growth area keeps county zoning until the city annexes it, and farther out most ground is farm or forest zoned, where a new house must qualify under state and county rules. Once a dwelling is allowed, a pole barn home is a practical way to get a wide shop bay and living space under one roof.

Does annexation or zoning change what I can build near Lebanon?

Yes. When the city annexes land, jurisdiction moves from Linn County to Lebanon and the parcel gets the city zone that matches the Comprehensive Plan map; it cannot keep its county zone. That city zone then sets the setbacks, lot rules and uses for your barndominium.
