Washington Coast

ADUs, beach cabins, and small homes on the Washington coast

We build from the Long Beach Peninsula and Willapa Bay up through Westport, Ocean Shores, and the north beaches to Sequim, Port Angeles, and Port Townsend. We file the permit with the city or county, build your home in our factory in Battle Ground, in Southwest Washington, and deliver and set it. On a coast lot, we start with the septic system, the tsunami and shoreline maps, and the county’s 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 gets to the coast

Every Wolf home leaves the factory as an oversize load on a Washington transport permit. The route we take depends on which stretch of coast you’re on.

Along the Columbia

SR 4 follows the river west from Longview to US 101. It’s the shortest trip from our factory to the ocean.

Ilwaco, Long Beach, Ocean Park, Chinook

Through the Chehalis valley

We take US 12 west to Aberdeen, then SR 105 or SR 109 out to the beach towns. The trickiest part is usually the sandy lots and narrow beach roads at the end.

Westport, Grayland, Ocean Shores, Pacific Beach, Moclips

Around Hood Canal

We reach the north Olympic Peninsula on US 101 up Hood Canal, or on SR 104 across the Hood Canal Bridge. These are our longest runs, so we quote them after we’ve looked at your site.

Port Townsend, Sequim, Port Angeles, Forks

The highway is usually the easy part. The last stretch is where it gets tight: sandy beach roads, power lines, shore pines, and summer traffic. We drive the route to your lot during the evaluation.

Area by area

Who permits your coast town

Most coast towns are small cities with their own code, and the beach communities in between go to the county. Find your area below, then open the town page or county guide for the full rules.

Long Beach Peninsula and Willapa Bay

Pacific County

Ilwaco, Seaview, Long Beach, Ocean Park, Nahcotta, Oysterville, Chinook, Raymond, South Bend, Tokeland

Permits:: Long Beach, Ilwaco, Raymond, and South Bend review their own permits; Seaview, Ocean Park, and the rest of the peninsula go to Pacific County
Delivery:: I-5 to Longview, then SR 4 along the Columbia to US 101. This is the closest stretch of coast to our factory.

On unincorporated Pacific County land, an ADU can be up to 1,200 square feet, and the permit goes through a Type I administrative review with no public notice. If you have a house and an ADU on the same lot, only one of them can be licensed as a vacation rental. The peninsula is open sand, so we spend our time on wind, drainage, and septic. We’ve built a Model J and a Model F in Long Beach and a tiny home in Ocean Park.

Grays Harbor and the north beaches

Grays Harbor County

Westport, Grayland, Aberdeen, Hoquiam, Cosmopolis, Ocean Shores, Ocean City, Copalis Beach, Pacific Beach, Moclips, Seabrook

Permits:: Aberdeen, Hoquiam, Cosmopolis, Westport, and Ocean Shores review their own permits; Grayland, the north beaches, and other unincorporated land go to Grays Harbor County Planning
Delivery:: I-5 to US 12 at Grand Mound, west to Aberdeen, then SR 105 to Westport and Grayland or SR 109 to Ocean Shores and the north beaches.

Your mailing address won’t tell you who issues the permit here, so we look it up from the parcel. On rural county land, septic and well limits are usually the sticking point: you have to show the lot can support a second home before a cottage makes sense. Ocean Shores and Westport lots are flat and sandy. Aberdeen and Hoquiam bring river flooding and hillside streets.

Sequim, Port Angeles, and the north Olympic Peninsula

Clallam County

Sequim, Port Angeles, Joyce, Forks, Clallam Bay, Sekiu, Carlsborg, Agnew

Permits:: Sequim, Port Angeles, and Forks review their own permits; Carlsborg, Agnew, Joyce, and other unincorporated land go to Clallam County
Delivery:: I-5 to Olympia, then US 101 north along Hood Canal, or across the Hood Canal Bridge on SR 104.

Outside urban growth areas, a detached ADU in Clallam County generally needs at least 1.5 acres. It can’t be bigger than 1,250 square feet or 50% of the main house, whichever is smaller, though units of 400 square feet or less are exempt from that size rule. You can rent the house or the ADU as a vacation rental, but not both. We’ve set a Model K and a Model E in Port Angeles and a Model E in Sequim.

Port Townsend and east Jefferson County

Jefferson County

Port Townsend, Port Hadlock, Irondale, Chimacum, Nordland, Quilcene, Brinnon

Permits:: City of Port Townsend inside city limits; Port Hadlock, Chimacum, Marrowstone Island, and the Hood Canal towns go to Jefferson County
Delivery:: US 101 up Hood Canal, then SR 104 and SR 19 or SR 20 into Port Townsend.

Jefferson County caps an ADU at 1,250 square feet of gross floor area. In the Port Townsend and Irondale/Port Hadlock urban growth areas you can have up to two ADUs per lot, and how close you are to sewer can decide eligibility. Short-term rentals get registered separately. We built a Model E vacation home in Port Townsend.

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 inland. Here’s what we check on every coast address.

Tsunami zones and dunes

The Long Beach Peninsula, Ocean Shores, and Westport are low and sandy, and a lot of that ground is in a mapped tsunami zone. Dune lots can mean extra review. We pull the state tsunami map and the local code for your address.

Shoreline and flood

If you’re near the ocean, Willapa Bay, Grays Harbor, or the Strait, your lot may fall under Washington’s Shoreline Management Act. The Chehalis and Willapa bottoms have FEMA flood zones. Either one can move where the home sits or change the foundation.

Wind and salt air

Open ocean lots get hit with strong winter wind, and the foundation and tie-downs have to be built for it. If your home will face the salt spray, ask us about the optional Coastal Package.

Septic and water

Most rural coast lots are on septic, and many are on wells or small water systems. The county has to sign off that your system can take another home before the permit moves forward.

Cabin, ADU, or vacation rental

What the county will call your beach cabin

Pacific and Clallam counties allow a vacation rental on a lot with an ADU, but only one of the two homes can be rented that way. Which rules you’re under depends on what’s already on your lot 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 lot and the cabin has a kitchen and bath, plan on an ADU permit and its size cap. That’s 1,200 square feet in Pacific County and 1,250 square feet in Jefferson and Clallam counties. Clallam also caps a detached ADU at half the size of the main house.

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.

One vacation rental per lot

In Pacific and Clallam counties, if you have a house and an ADU, only one of them can be a vacation rental. Jefferson County registers rentals separately, and the cities have their own rules.

On the coast

Wolf homes already on the Washington coast

We’ve set homes from the Long Beach Peninsula up to the Strait, including a Model J and a Model F in Long Beach, tiny homes in Ocean Park, Model Es in Sequim, Port Angeles, and Port Townsend, and a Model K in Port Angeles.

Cream Wolf Model J home with a covered porch and white railings under tall evergreens in Long Beach, Washington — Model J, Long Beach

Sage green Wolf Model E home with a wood deck and steps in front of tall firs in Sequim, Washington — Model E, Sequim

Navy Wolf Model E home with a red front door, wood accent corner, and cedar steps in Port Angeles, Washington — Model E, Port Angeles

Tiny homes in Ocean Park

A one-bedroom beach cabin with a covered porch on a raw coastal lot, built to work as a family getaway or a rental.

Vacation home in Long Beach

The owner bought a Long Beach lot for vacations and didn’t want to rough it in an RV, so they put a Wolf home on it.

Models

Plans that suit a coast lot

Our smaller plans fit the county ADU caps and the narrow beach lots. On a vacant lot, a bigger plan can be your main house. 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 cabin or ADU in a 12×36 plan, from $85,500 for the home. We set one in Port Angeles, and it fits under every county cap on this page.

Model E / F — 616 sq ft

Two bedrooms in a 14×44 plan, from $97,500 for the home. We’ve set it in Sequim, Port Angeles, Port Townsend, and Long Beach.

Model J — 828 sq ft

Two bedrooms and two baths with a covered porch, from $156,500 for the home. A full-time beach house, like the Long Beach 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 Seaview, Ocean Park, Grayland, the north beaches, or Port Hadlock
What kind of home it is (ADU or main house) and which size cap and acreage rule apply
Tsunami, shoreline, dune, and flood maps for your address
Your septic capacity, and your well or water system
Our delivery route, the oversize-load permit, and the last turns off US 101
Getting onto the lot: sandy roads, 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 septic work, a raised foundation, or a shoreline review. You’ll see each of those as its own line in the proposal. See cost and financing.

Questions

Washington coast ADU and cabin questions

Do you build ADUs and cabins on the Washington coast?

Yes. We build your home in our factory, file the permit with the city or county, and deliver and set it. We’ve built in Long Beach, Ocean Park, Sequim, Port Angeles, and Port Townsend. The best place to start is a free property evaluation.

Can a coast ADU be a vacation rental?

Sometimes, with limits. On a Pacific County lot with a house and an ADU, only one of the two can be licensed as a vacation rental. In Clallam County, you can rent the house or the ADU that way, but not both. Jefferson County registers short-term rentals separately, and the coast cities have their own rules. Make sure the rental path is clear before you count on nightly income. There’s more on vacation rental ADUs.

How big can an ADU be on the Washington coast?

That depends on who permits your lot. Pacific County allows up to 1,200 square feet. Clallam County limits a detached ADU to 1,250 square feet or 50% of the main house, whichever is smaller, and outside urban growth areas the lot generally needs 1.5 acres. Jefferson County caps an ADU at 1,250 square feet. Grays Harbor County and the cities set their own standards. Inside urban growth areas, Washington’s statewide ADU law (HB 1337) applies too.

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 near the shoreline?

Often, yes, but we need to check the lot first. We look at the state tsunami map, the FEMA flood map, and whether your lot falls under the Shoreline Management Act or a dune or critical-area overlay. Any of those can set where the home sits and what the foundation looks like.

How much more does a coast project cost?

The home costs the same. The site work costs more: longer transport, oversize-load permits, crew travel, and sometimes septic work, a raised foundation, or a shoreline review. 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 Long Beach, Ilwaco, Raymond, South Bend, Aberdeen, Hoquiam, Westport, Ocean Shores, Sequim, Port Angeles, Forks, or Port Townsend, the city does. Seaview, Ocean Park, Grayland, the north beaches, Port Hadlock, and the other unincorporated communities go to the county. Either way, Washington L&I approves the factory-built home.

What about salt air?

Every Wolf home is built to the Washington 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.
