Oregon Coast

ADUs, beach cottages, and small homes on the Oregon coast

We build from Astoria and Cannon Beach down through Tillamook, Lincoln City, Newport, and Florence to Coos Bay. 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 Coast Range. Before we talk floor plans on a coast lot, we look up the tsunami and flood maps, the ADU size cap, and the rental rules, 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 crosses the Coast Range

Every Wolf home leaves the factory as an oversize load on an Oregon transport permit. Which highway we take over the Coast Range depends on where your town sits on US 101.

North coast

US 30 and US 26 are the shortest runs from our factory to the ocean.

Astoria, Seaside, Cannon Beach, Manzanita, Tillamook

Central coast

OR 18, US 20, and OR 34 all cross the Coast Range with curves and grades we have to plan an oversize load around. The transport permit spells out the exact route.

Lincoln City, Depoe Bay, Newport, Waldport, Yachats

South coast

OR 126, OR 38, and OR 42 come over from I-5. These are our longest deliveries, so we quote transport after we’ve looked at your site.

Florence, Reedsport, Coos Bay, Bandon, Brookings

The highway is usually the easy part. The last few blocks are where it gets tight: narrow beach-town streets, power lines, shore pines, and summer traffic. We drive the route to your lot during the evaluation.

County by county

Who permits your coast town

Most coast towns have their own city code, and the unincorporated beach communities go to the county. Find your county below, then open the town page or county guide for the full rules.

Clatsop County — north coast

Astoria, Warrenton, Gearhart, Seaside, Cannon Beach, Arch Cape

Permits:: Each city has its own code and permit counter; Arch Cape and other unincorporated lots go to Clatsop County
Delivery:: US 30 along the Columbia to Astoria, or US 26 over the Coast Range to Seaside and Cannon Beach. This is the closest stretch of coast to our factory.

Astoria, Warrenton, Gearhart, Seaside, and Cannon Beach each have their own ADU rules, so we start with the city. Out on rural county land, a detached ADU can be up to 900 square feet, and you’ll record a covenant saying it won’t be used as a vacation rental. In Astoria it’s usually the hillside that drives the foundation design. In Seaside and Gearhart, it’s the sand and the drainage.

Tillamook County

Manzanita, Nehalem, Wheeler, Rockaway Beach, Garibaldi, Bay City, Tillamook, Oceanside, Netarts, Pacific City, Neskowin

Permits:: The incorporated towns review their own permits; Oceanside, Netarts, Pacific City, and Neskowin are unincorporated and go to Tillamook County
Delivery:: OR 6 over the Wilson River pass to Tillamook, or US 26 to US 101 south for the north Tillamook beach towns.

Under the county code, an ADU can’t be bigger than 800 square feet or 75% of the main house, whichever is smaller, and you can’t rent it out as transient lodging. Pacific City and Neskowin don’t have a city hall, so the county reviews those lots. In the Tillamook valley we look hard at river flooding, and in the beach towns we look at the dunes.

Lincoln County — central coast

Lincoln City, Depoe Bay, Newport, Waldport, Yachats, Gleneden Beach, Otter Rock, Seal Rock

Permits:: Each city reviews its own permits; the Lincoln City, Newport, and Toledo growth boundaries use city code, and unincorporated lots go to Lincoln County
Delivery:: OR 18 to Lincoln City, US 20 to Newport, or OR 34 to Waldport.

Where the county’s own rules apply, an ADU can’t be bigger than 800 square feet or 75% of the main house, whichever is smaller. Short-term rentals need their own county license, and those licenses are capped by area with a waitlist. Getting an ADU permit doesn’t get you a rental license. We’ve built here before, including a Model I in Newport and a vacation home in Yachats.

Florence and the Lane County coast

Florence, Dunes City, Heceta Beach

Permits:: City of Florence or Dunes City inside their limits; unincorporated coast lots go to Lane County
Delivery:: OR 126 west from Eugene.

Florence sits on the Siuslaw at the north end of the Oregon Dunes, and building on dune sand takes a different foundation than a lot in the valley. On rural Lane County land zoned Rural Residential, an ADU can be up to 900 square feet, and you’ll record a covenant saying it won’t be a vacation rental.

Reedsport and the Douglas County coast

Reedsport, Winchester Bay, Gardiner

Permits:: City of Reedsport inside city limits; Winchester Bay and Gardiner go to Douglas County
Delivery:: OR 38 along the Umpqua from I-5.

Reedsport sits at the mouth of the Umpqua, so we pull the flood map on every lot before anything else. City permits start with a planning review, and county lots follow the county’s rural rules.

Coos Bay and the south coast

Coos Bay, North Bend, Bandon, Lakeside, Charleston

Permits:: Coos Bay, North Bend, Bandon, and Lakeside have their own codes; unincorporated lots go to Coos County
Delivery:: OR 42 from I-5 near Roseburg, or US 101 south from Reedsport.

Inside city growth boundaries, Oregon law requires cities of more than 2,500 people to allow ADUs. Outside them, you can only build a rural ADU if the county has adopted a program for it, so we check your zone before we talk plans. It’s a long haul from the factory, and we quote delivery after we’ve seen the site.

Oregon ADU rules

Curry County — far south coast

Port Orford, Gold Beach, Brookings

Permits:: Each city has its own code; unincorporated lots go to Curry County
Delivery:: US 101 south from Coos Bay. This is our longest delivery on the Oregon coast.

We take Curry County projects one at a time. Down here, the distance, the drive down US 101, and getting onto your lot affect the price as much as the house does.

Oregon ADU rules

Coastal lots

What a coast lot adds to the evaluation

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

Tsunami zones, dunes, and bluffs

A lot of the developed coast is in a mapped tsunami zone, and oceanfront lots fall under Oregon’s beach and dune rules (Goal 18). Dune and bluff lots often need a geologic hazard report before you can get a permit. We pull the state tsunami map and any local overlay for your address.

Flood zones

The bays and river mouths (Tillamook Bay, the Nehalem, the Siuslaw, the Umpqua, and Coos Bay) have FEMA flood zones. If your lot is in one, the flood map can set how high the floor sits and what kind of foundation you need.

Wind and salt air

Lots right on the ocean take a lot more wind, and the foundation and tie-downs have to be designed for it. If your home will face the salt air, ask us about the optional Coastal Package for extra protection.

Septic and water

Plenty of unincorporated coast lots run on septic and small water districts. Your septic system has to handle another home, and sandy soil or high groundwater can limit where the drain field goes.

Cottage, ADU, or vacation rental

What the county will call your beach cottage

Coast counties keep a close eye on vacation rentals, and several of their rules single out ADUs. Which rules you’re under depends on what’s already on your lot and how you plan to use the home.

A cottage behind the house is usually an ADU

If there’s already a house on the lot and the cottage has a kitchen and bath, plan on an ADU permit and the size cap that comes with it. That’s 800 square feet or less under the Tillamook and Lincoln county codes, and 900 square feet for rural ADUs in Clatsop and Lane counties.

On a vacant lot, it's the main home

If your beach lot 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 lot allows it.

Vacation rentals need their own approval

Tillamook County doesn’t allow transient lodging in ADUs. Rural ADUs in Clatsop and Lane counties come with a no-vacation-rental covenant, and Lincoln County caps rental licenses. Make sure you have a rental path before you budget for nightly income.

Vacation and getaway homes Vacation rental ADUs Long-term rental ADUs

On the coast

Wolf homes already on the Oregon coast

We’ve set homes from Seaside down to Florence, including Model Es in Neskowin, Rockaway Beach, and Florence, a Model F in Tillamook, and a Model I in Newport.

Navy Wolf Model E home with white trim and a long wood deck in Neskowin, Oregon — Model E, Neskowin

Bright blue Wolf Model F home with a yellow door, wood accent panel, and a covered entry in Tillamook, Oregon — Model F, Tillamook

Red Wolf Model I home with a covered front porch and wood railings among evergreens in Newport, Oregon — Model I, Newport

Vacation home in Yachats

An investor put a 616-square-foot Model E on the coast as a vacation rental, then used it as the template for more small units.

Vacation home in Long Beach, Washington

Just across the Columbia from Astoria. The owner planned to camp in an RV and chose a Wolf home instead.

Models

Plans that suit a coast lot

Beach lots tend to be narrow, and coast ADU caps run 800 to 900 square feet, so most people start with our smaller plans. The prices below are for the home only. We quote coast 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 beach cottage or ADU in a 12×36 plan, from $85,500 for the home. It fits under the 800-square-foot county caps with room to spare.

Model E / F — 616 sq ft

Two bedrooms in a 14×44 plan, from $97,500 for the home. We’ve set this one in Neskowin, Rockaway Beach, Florence, and Yachats.

Model I — 1,232 sq ft

Three bedrooms and two baths, from $178,500 for the home. A full-size main house, like the Newport home in the photos.

Property evaluation

What we check first on a coast lot

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

Who issues your permit: the city, or the county if you’re in Pacific City, Neskowin, Oceanside, Arch Cape, or another unincorporated town
What kind of home it is (ADU or main house) and which size cap applies
Tsunami, beach and dune, bluff, and flood maps for your address
Your septic capacity or sewer, and your water district or well
Our route over the Coast Range, the oversize-load permit, and the last turns off US 101
Getting onto the lot: street width, power lines, trees, summer parking, and room for the crane

Coast jobs have some costs a lot near our factory doesn’t: longer transport, oversize-load permits, crew travel, and sometimes a raised foundation or a geologic report. You’ll see each of those as its own line in the proposal. See cost and financing.

Questions

Oregon coast ADU and cottage questions

Do you build ADUs and cottages on the Oregon coast?

Yes. We build your home in our factory, file the permit with the city or county, and bring it over the Coast Range. We’ve built on the coast in Florence, Neskowin, Newport, Rockaway Beach, Seaside, Tillamook, and Yachats. The best place to start is a free property evaluation.

Can I use a coast ADU as a vacation rental?

Usually not. Tillamook County doesn’t allow transient lodging in an ADU. Rural ADUs in Clatsop and Lane counties come with a recorded covenant against vacation use. Lincoln County caps short-term rental licenses and keeps a waitlist. And Oregon law lets cities regulate vacation use of ADUs on their own terms. Unless your parcel has a clear rental path, plan the ADU for family or a long-term tenant. There’s more on vacation rental ADUs.

How big can an ADU be on the Oregon coast?

That depends on who permits your lot. Under the county codes, Tillamook and Lincoln counties cap an ADU at 800 square feet or 75% of the main house, whichever is smaller. Rural ADUs in Clatsop and Lane counties can be up to 900 square feet. Cities set their own limits. Model K (432 sq ft) and Model E (616 sq ft) fit under every one of those caps.

Is a beach 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 a vacant lot, 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 build in a tsunami zone or on a dune?

Often, yes, but we need to check the lot first. We look at the state tsunami map, Oregon’s beach and dune rules, the FEMA flood map, and any local hazard overlay. Oceanfront, dune, and bluff lots often need a geologic report, and in a flood zone the map can set your floor height and foundation.

How much more does a coast project cost?

The home costs the same. The site work costs more: transport over the Coast Range, oversize-load permits, crew travel, and sometimes a raised foundation, a geologic report, or septic work. Our published installation baseline covers sites within 20 miles of the factory, so we quote coast 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, the city does. Pacific City, Neskowin, Oceanside, Netarts, Arch Cape, Gleneden Beach, and the other unincorporated communities go to the county. In Lincoln County, the Lincoln City, Newport, and Toledo growth boundaries use city code even outside city limits. Either way, Oregon’s Building Codes Division approves the factory-built home.

What about salt air?

Every Wolf home is built to the Oregon residential code for Northwest weather. If your lot gets salt spray and ocean wind, ask about the optional Coastal Package for extra marine-weather protection.
