Boardman sits on the Columbia River in Morrow County. Irrigated farmland, Port of Morrow traffic, strong wind, and summer heat all shape a building site here. It’s a long way from our factory, so we take on modular ADUs and small homes here by arrangement. First we check the route, staging space, utilities, and local requirements. The distance means more planning up front. Even so, a residential lot with a clear route and room to stage works well as a long-haul modular set.
Our Oregon ADU rules guide covers the statewide rules inside urban growth boundaries. Size caps, rural acreage rules, and setbacks (how far a building sits from the property lines) come from Boardman or Morrow County. They set local siting and fees, and we check them for your parcel.
Wasco County’s 900 sq ft / two-acre rural ADU numbers don’t apply to a Boardman city lot. Don’t assume them for Morrow County either without checking Morrow’s ordinance. Portland’s 800 sq ft cap doesn’t apply here.
Boardman city limits or Morrow County
You work with the City of Boardman or Morrow County on zoning, building codes, utility connections, site prep, and inspections. The first question is which one has your lot. In-town lots near the river and the highway are usually city. Irrigated ground, industrial-adjacent parcels, and land on county roads are often Morrow County, even when the owners shop in Boardman.
Oregon’s ADU mandate applies inside UGBs in qualifying cities. Boardman’s population and code details still need a local check, including whether your zone is residential at all. Port-industrial and commercial land generally won’t allow an ADU. Rural resource land may not allow a second home the way a city R zone does.
Permits can include WAVE, septic, propane, legal lot, road approach, wetlands, and fire sprinkler. On the Columbia plateau, pay close attention to water, legal lot, road approach, and wind/exposure. Irrigation water doesn’t automatically count as domestic water for a second home.
Neighborhoods, port land, and irrigated ground
ADU projects usually start on Boardman’s in-town residential streets. Those lots have a house, a yard, city utilities, and a zone that lists dwellings. Closer to the Port, the data-center and industrial campuses, or the interstate interchanges, the land-use rules change.
From I-84, irrigated circles and farm parcels look like plenty of room for a cottage. But acreage doesn’t make a dwelling legal, and a farm dwelling exemption works differently from the ADU statute.
Hermiston is in Umatilla County, The Dalles is in Wasco County, and Madras is in Jefferson County. Their requirements don’t carry over to a project in the City of Boardman or Morrow County.
Columbia River wind affects both the structure and the crane’s load chart. Summer heat on the plateau makes cooling a must. Sandy or irrigated soils change foundation design and how deep utilities get buried. Flood maps along the river and some drainages need to be checked in the first week.
Delivery and access
The trip from our factory in Battle Ground, just north of Portland, usually follows I-84 through the Columbia River Gorge. Wind in the Gorge and on the plateau can delay a wide load, and extreme heat can change the set-day schedule. So wind windows go on the calendar.
We also need room on or next to the property to stage the truck and crane. A narrow farm lane, a soft shoulder, an irrigation pivot, or an overhead line is much easier to solve when we see it early.
The last two miles might be a city street, a county road, or an irrigated shoulder next to a pivot. We ask for three access photos: overhead lines in the wind, the pivot’s swing, and any soft shoulder. If you can’t get those photos, we start from the taxlot.
Our first job is confirming that the home can reach the site and be set safely. That’s what “by arrangement” means here. We do a full site review before anyone spends money on plans or reserves a factory slot. We price the longer haul after we confirm the site, access, and route.
Modular, not HUD or an RV
Eastern Oregon has plenty of manufactured homes and destination trailers. Wolf builds Oregon modular homes to residential code, with a state insignia, a permanent foundation, and a local installation permit. A Boardman ADU or cottage we set is a permanent dwelling. Park models and HUD-labeled homes are a different category. Tiny homes, ADUs, and small primary homes all come from the same factory as long as they’re dwellings.
HUD manufactured homes are still common in Morrow County. If the city’s only practical path for your parcel is a manufactured-home installation, we’ll tell you. In that case you’d work with a manufactured-home dealer instead.
Models worth considering
- Model K (~432 sq ft) for efficient one-bedroom housing for family, a guest, or a workforce rental where the zone allows it.
- Model F (~616 sq ft) when you need two bedrooms.
- Model I (~1,232 sq ft) for a larger household, or a small primary home on a lot that can take the width and the legal size.
A home that’s comfortable year-round
In Boardman, a comfortable small home means planning for afternoon sun, winter wind, and the way people come and go every day. We can talk through window placement, a covered entry, exterior finishes, storage, and where an outdoor sitting area makes sense on the lot.
Standard Wolf packages include a ductless mini-split for heating and cooling. Siting the home for west sun and wind exposure keeps the rooms more comfortable before the equipment even turns on.
If the home is for a parent or another family member, tell us how they live now and what would make daily life easier. If it’s for a local worker or a long-term tenant, we can focus on a practical layout and durable finishes. The goal is a home that feels private without feeling cut off from the main property.
How people use small homes here
Boardman owners ask about homes for family and housing for someone who works at the port or a local plant. Others want guest cottages or smaller primary homes on land they already own. At this distance, long-term housing is usually the clearest fit.
A river view or easy I-84 access doesn’t make short-term lodging legal. A property marketed as a “Columbia River tiny home getaway” still needs zoning, water, access, and short-term rental approval. If rental income is part of the plan, we check the intended use with the local jurisdiction before recommending a home. Noise, truck routes, and industrial easements can also affect how livable a site is, even where a dwelling is allowed.
How a Boardman permit runs
- Research zoning with the city or Morrow County.
- Confirm the structure type (ADU, guest house, hardship dwelling, or primary).
- Plan domestic water, sewer or septic, and power.
- File complete site and installation drawings for a state-inspected modular dwelling.
- Inspect the foundation, set, and utilities, then get occupancy.
Most Boardman lots won’t need a forest-practice review, but many will need solid paperwork for water and access. Review time depends on the city or county queue. An incomplete legal-lot or road-approach file is the usual reason one stalls.
Factory build and set day
Once the city or county issues the permit, the home is built indoors at our factory while the site work gets done in Boardman. That keeps the framing out of the weather. It also lets the foundation, trenching, and utility work happen on the lot at the same time. Once the pad passes inspection, we schedule the haul around the Gorge wind forecast and the summer heat as well as the calendar.
Set day is the day the home is placed on its foundation. The truck needs the staging area we confirmed during site planning. The crane needs a clear swing past any overhead lines and the irrigation pivot. We weather-seal the home the same day. Then we finish the mechanical, plumbing, and electrical tie-ins, with one more day on site if a two-piece plan has to be joined. After that come the inspections, occupancy, keys, and a punch-list walk-through with the crew that set the house.
Water, septic, and power
Domestic water is often the deciding question on a Boardman parcel. In town, the second home usually connects to city water and sewer, and we check lateral lengths and panel capacity. Outside city limits, a well, a septic system, and a road approach may each need their own approval as part of the Morrow County file. We want to know which of those you already have before we recommend a model. A lot that works on paper can stall on water.
What affects the project cost
The model sets the starting home price, and we price the rest after we’ve seen the property. Long-distance delivery, foundations in sandy or irrigated soil, water service, and wind-related installation details can all change the total project cost. We also confirm SDCs and connection fees with the city or county. See our financing page if you plan to use a lender.
What an evaluation covers
Send the address, the taxlot if you have it, photos of the access and the proposed pad, utility status, and who will live there.
The free property evaluation is our first look at zoning, setbacks, and what’s generally allowed. For Boardman, that covers:
- City of Boardman versus Morrow County, and whether the zone allows this type of dwelling.
- Legal lot status.
- The intended use: family, workforce rental, or something the zone doesn’t allow.
As the project moves forward, we check the site itself:
- Domestic water (not just irrigation), sewer versus septic, and electrical capacity.
- The I-84 / Gorge delivery window, wind, last-mile access, and staging.
- The road approach.
- Whether a K, F, or I can be both permitted and physically set after the haul.
Punch-list and warranty work are planned trips to eastern Oregon by the same crews who built and set the home. That’s why we only take projects at this range that we’re confident we can support.
If you already own the parcel, send the taxlot. If you’re buying irrigated ground and hoping a cottage will just drop in, make the evaluation part of your due diligence before closing. Morrow County surprises after closing are expensive.
Send the address. If the lot can take a Wolf model, we’ll tell you and price the haul. If it can’t, you’ll know before you commit to a factory slot.
