Cascade Mountains

Mountain cabins, ADUs, and small homes in the Cascades

We build in Leavenworth, Lake Chelan, Cle Elum, and the Methow on the Washington side, around Mt. Hood, Hood River, and Bend in Oregon, and in the Gorge and Mt. Adams country in between. We file the permit with the city or county, build your home in our factory in Battle Ground, just north of Portland, and bring it over the pass or up the Columbia. Before we talk floor plans on a mountain lot, we look at snow load, wildfire rules, water, and winter access, because those tend to decide what you can build.

Where Wolf works

In Washington and Oregon, Wolf employees handle your project from property review and permits through construction, site work, delivery, and installation. Some projects require third-party services, such as surveys or septic design and installation, depending on the property and jurisdiction. Beyond Washington and Oregon, local contractors complete site work and utility connections.

Getting there

How the home gets to the mountains

Every Wolf home leaves the factory as an oversize load on a state transport permit. Whether we go over a pass or up the Columbia depends on which side of the range you’re on.

Along the Columbia

SR 14 and I-84 follow the river through the Gorge at low elevation, and from there US 97 heads north or south. That gets us to the east side without crossing the Cascade crest.

White Salmon, Trout Lake, Goldendale, Ellensburg, Wenatchee, Chelan, the Methow, Bend

Over the passes

I-90 over Snoqualmie, US 2 over Stevens, and US 26 over Mt. Hood are the direct routes. A winter storm can close a pass or hold oversize loads, so we schedule mountain sets around the weather.

Cle Elum, Roslyn, Leavenworth, Government Camp

West-side valleys

Foothill towns are a short drive up a river valley from I-5. Getting onto the lot is usually the hard part: steep driveways, tight turns, and tall timber.

Area by area

Who permits your mountain lot

Most mountain towns are small cities with their own code, and the cabins and resort communities around them go to the county. Find your area below, then open the town page or county guide for the full rules.

Columbia Gorge and Mt. Adams

Skamania and Klickitat counties, WA

Stevenson, North Bonneville, Carson, Underwood, White Salmon, Bingen, Husum, Trout Lake, Goldendale, Centerville

Permits:: Stevenson, North Bonneville, White Salmon, Bingen, and Goldendale review their own permits; Carson, Underwood, Trout Lake, and other unincorporated land go to the county
Delivery:: SR 14 east along the Columbia. This is the closest mountain country to our factory.

A lot of land along the river is inside the Columbia River Gorge National Scenic Area, which adds its own review on top of the county’s, so that’s the first thing we check. Wind and steep grades affect both the delivery and the foundation. We’ve set a Model E in Carson and another near Centerville with Mt. Adams right on the horizon.

Mt. Hood and Hood River

Clackamas and Hood River counties, OR

Welches, Brightwood, Zigzag, Rhododendron, Government Camp, Hood River, Odell, Parkdale

Permits:: The US 26 mountain communities are unincorporated and go to Clackamas County; the City of Hood River reviews in-town lots, and the upper valley goes to Hood River County
Delivery:: US 26 up the mountain from Sandy, or I-84 through the Gorge to Hood River. We time US 26 deliveries around the weather.

A rural Clackamas County ADU can be up to 900 square feet, has to sit within 100 feet of the main house, and can’t be a short-term rental. Government Camp gets a lot more snow than Welches, so we design the structure for your lot’s elevation. Keep in mind that a driveway that’s fine in August can be impassable in January.

Bend, Sisters, and Central Oregon

Deschutes County, OR

Bend, Sisters, Redmond, La Pine, Sunriver, Tumalo, Terrebonne

Permits:: Bend, Sisters, Redmond, and La Pine review their own permits; rural land goes to Deschutes County
Delivery:: US 97 south from the Columbia at Biggs, or US 26 over Mt. Hood through Madras.

A rural Deschutes County ADU needs at least 2 acres (5 acres in parts of south county) and can be up to 900 square feet. Neither the ADU nor the main house can be a vacation rental. You can’t build a rural ADU in the unincorporated communities of Sunriver, Tumalo, or Terrebonne. The county also wants a septic site evaluation before the land-use application, plus written sign-off from the fire district on your access.

Cle Elum, Roslyn, and the Kittitas Valley

Kittitas County, WA

Cle Elum, Roslyn, South Cle Elum, Ronald, Easton, Ellensburg, Thorp

Permits:: Cle Elum, Roslyn, South Cle Elum, and Ellensburg review their own permits; Ronald, Easton, Thorp, and rural land go to Kittitas County
Delivery:: I-90 over Snoqualmie Pass, or US 97 north from the Columbia without crossing the crest.

On rural Kittitas County land, you need at least 3 acres for an ADU, you get one per lot, and it can be up to 1,500 square feet. Having a well on the property doesn’t prove you have a legal water supply for a second home, so we ask for your water and septic records early. At the east end of the pass, snow and wind affect both the roof design and the set.

Leavenworth, Wenatchee, and Lake Chelan

Chelan County, WA

Leavenworth, Cashmere, Wenatchee, Entiat, Chelan, Manson, Plain

Permits:: Leavenworth, Cashmere, Wenatchee, Entiat, and Chelan review their own permits; Manson, Plain, and rural land go to Chelan County
Delivery:: US 97 north through Ellensburg and over Blewett Pass, or US 2 over Stevens Pass.

A Chelan County mailing address doesn’t tell you who issues the permit, so the first thing we do is figure that out. Lake Chelan lots can fall under shoreline rules, and plenty of hillside and canyon lots have wildfire or critical-area notes that change where the home can go. We’ve set a Model E in Chelan and a Model J right on the lake in Manson.

Methow Valley

Okanogan County, WA

Winthrop, Twisp, Mazama, Carlton

Permits:: Winthrop and Twisp review their own permits; Mazama, Carlton, and rural land go to Okanogan County
Delivery:: US 97 up the Columbia to Pateros, then SR 153 up the valley. The North Cascades Highway (SR 20) closes for the winter, so we come in from the south.

The Methow is the farthest mountain valley we cover here. Wildfire, wells, and septic are the first things we look at on a Methow lot. We’ve set a Model J in Winthrop.

Washington ADU laws

West-side foothills: Mt. Baker, Skykomish, and White Pass

Whatcom, Snohomish, and Lewis counties, WA

Acme, Deming, Glacier, Maple Falls, Index, Gold Bar, Sultan, Sunset Falls, Packwood, Randle

Permits:: Sultan, Gold Bar, and Index review their own permits; Acme, Glacier, Sunset Falls, Packwood, and Randle go to the county
Delivery:: I-5 north to SR 9 or SR 542 for Mt. Baker, US 2 up the Skykomish, or US 12 east to Packwood.

On the west side, mountain lots get heavy rain and deep timber. Steep driveways, big trees, river flooding, and well and septic capacity are what usually come up. We’ve set a Model J near Acme and a Model E at Sunset Falls on the Skykomish.

Mountain lots

What a mountain lot adds to the evaluation

You can put a Wolf home on a mountain lot, but expect a few reviews you wouldn’t get in the valley. Here’s what we check on every mountain address.

Snow load

Snow loads go up fast as you gain elevation. A lot at Government Camp, Snoqualmie Pass, or Leavenworth needs a lot more roof capacity than one down in the valley, so we design the structure for your address.

Wildfire

East-side pine and grass country has real fire risk. Counties can require the fire district to sign off on your access, plus defensible space and ignition-resistant materials. Deschutes County won’t approve a rural ADU without that sign-off.

Water and septic

Most mountain lots are on a well and septic. A well on the property doesn’t prove you have a legal water supply for a second home, and some counties, Deschutes among them, want the septic evaluation before the land-use application.

Winter access

Expect the county to look at your driveway grade, turnaround, snow plowing, and fire-truck access. We deliver once the pad is ready and the roads are passable.

Cabin, ADU, or vacation rental

What the county will call your mountain cabin

Rural mountain counties keep ADUs on a short leash, and Clackamas and Deschutes counties don’t allow vacation rentals in rural ADUs at all. Which rules you’re under depends on what’s already on your land and how you plan to use the home.

A cabin behind the house is usually an ADU

If there’s already a house on the land and the cabin has a kitchen and bath, plan on an ADU permit and its limits. That’s 900 square feet on rural land in Clackamas and Deschutes counties, and 1,500 square feet on 3 or more acres in rural Kittitas County.

On vacant land, it’s the main cabin

If your mountain parcel is empty, a small Wolf home is usually permitted as the main house. The ADU caps don’t apply, and you can still add a bigger house later if the land allows it.

Vacation rentals need their own approval

Rural Clackamas County ADUs can’t be short-term rentals, and on rural Deschutes County land neither the ADU nor the house can be. Resort towns have their own rules. Make sure you have a rental path before you budget for nightly income.

Models

Plans that suit a mountain lot

Rural ADU caps in the mountains run 900 to 1,500 square feet, and narrower homes are easier to get up a steep driveway, so most people start with our smaller plans. The prices below are for the home only. We quote mountain delivery and site work after we’ve looked at your lot.

Keep the details you like as you browse. Local rules, the buildable area and the delivery route need review before we recommend a layout for your property.

Model K — 432 sq ft

A one-bedroom cabin or ADU in a 12×36 plan, from $85,500 for the home. It’s the easiest plan to get up a steep driveway, and it fits well under the 900-square-foot rural caps.

Model E / F — 616 sq ft

Two bedrooms in a 14×44 plan, from $97,500 for the home. We’ve set it in Chelan, Carson, Centerville, and Sunset Falls.

Model J — 828 sq ft

Two bedrooms and two baths with vaulted ceilings, from $156,500 for the home. This is the mountain house we set in Winthrop, Manson, and Acme.

Property evaluation

What we check first on a mountain lot

The free evaluation starts with your address. In the mountains, these are the questions we answer before we talk about finishes.

Who issues your permit: the city, or the county if you’re in Manson, Plain, Trout Lake, Government Camp, Sunriver, or another unincorporated community
What kind of home it is (ADU or main house) and which acreage and size rules apply
The snow load and wind we have to design for at your elevation
Wildfire rules, defensible space, and whether the fire district will sign off on your access
Your legal water supply, your well, and your septic capacity
Our route over the pass or up the Columbia, your driveway grade, and winter access

Mountain jobs have some costs a lot near our factory doesn’t: longer transport, oversize-load permits, crew travel, and often a well, septic work, a long driveway, or extra roof engineering for snow. You’ll see each of those as its own line in the proposal. See cost and financing.

Questions

Mountain cabin and ADU questions

Do you build cabins and ADUs in the Cascades?

Yes, on both sides of the range in Washington and Oregon. We build your home in our factory, file the permit with the city or county, and deliver and set it. We’ve built in Chelan, Manson, Winthrop, Carson, Centerville, Acme, and Sunset Falls. The best place to start is a free property evaluation.

Can a Wolf home handle mountain snow?

We design the structure for the snow load at your address. Snow loads climb quickly with elevation, so a lot at Government Camp or Snoqualmie Pass gets a different design than one in the valley. We confirm the design load for your site during the evaluation.

Can I use a mountain ADU as a vacation rental?

Often not. Rural ADUs in Clackamas County can’t be short-term rentals, and on rural Deschutes County land neither the ADU nor the main house can be a vacation rental. Resort towns like Leavenworth and Cle Elum have their own rental rules. Make sure the rental path is clear before you count on nightly income. There’s more on vacation rental ADUs.

How big can a rural ADU be in the mountains?

That depends on the county. Rural ADUs can be up to 900 square feet in Clackamas and Deschutes counties and 1,500 square feet in Kittitas County. Kittitas and Deschutes also have minimum parcel sizes (3 acres and 2 acres). Cities set their own limits. Inside Washington urban growth areas, the statewide ADU law (HB 1337) applies too.

Is a mountain cabin an ADU?

If there’s already a house on the lot and the cabin has a kitchen and bath, it’s usually an ADU, with the ADU size cap and rental limits that come with it. On vacant land, that same cabin is often permitted as your main home, and then the ADU caps don’t apply. We’ll confirm which way your parcel goes.

Can you deliver in winter?

Sometimes. A storm can close a pass or hold oversize loads, and the North Cascades Highway closes for the season. For the east side, we can often run along the Columbia and up US 97 instead of going over a pass. We schedule the set once your pad is ready and the route is open.

How much more does a mountain project cost?

The home costs the same. The site work costs more: longer transport, oversize-load permits, crew travel, and often a well, septic work, a long driveway, or extra roof engineering for snow. Our published installation baseline covers sites within 20 miles of the factory, so we quote mountain delivery and setup after we’ve looked at your site. The cost page has the baseline.

Who permits my lot: the city or the county?

If you’re inside a city like Leavenworth, Chelan, Cle Elum, Hood River, or Bend, the city does. Manson, Plain, Trout Lake, Government Camp, Welches, Sunriver, Mazama, and the other unincorporated communities go to the county. Either way, Washington L&I or Oregon’s Building Codes Division approves the factory-built home.
