Barndominium Builders in Kitsap County, Washington

Kitsap County is almost all peninsula: forested acreage, small farms and waterfront between Puget Sound and Hood Canal, with Bremerton, Port Orchard, Poulsbo and Bainbridge Island as its cities. Outside them, rural residential land commonly comes in five-acre parcels, which suits a barndominium with a covered shop, a boat or RV bay, or room for animals beside the living space. Kitsap County's Department of Community Development issues building permits for the unincorporated county, but on a well-and-septic parcel the Kitsap Public Health District reviews the septic design and the proposed water supply before that permit can be issued. The whole county sits in WRIA 15, where a new home on a new permit-exempt well carries a withdrawal limit and a fee. Our crews put up complete homes on peninsula acreage, and owners who would rather raise the frame themselves can buy barndominium kits from us instead. A custom plan is where most Kitsap projects begin, because the drainfield, its reserve area and the well radius all compete for the same cleared ground. For a lot inside Bremerton, the City's own permit office applies. Tell us which parcel you are looking at, and we will read its zone, the health district steps and the water situation with you before you make an offer.

Barndominium Kits and Pole Barn Homes in Kitsap County

A kit suits an owner who wants to raise the shell with their own crew. A pole barn home sets its frame on posts and trusses (the engineering term is post-frame construction) and suits a wide, simple layout with a shop bay under the same roof; a metal building home uses a bolted steel frame. Which one fits your parcel comes down to the zoning, the site and the design values the local building office publishes, covered below.

Building a Barndominium in Kitsap County: Permits, Zoning, Septic and Water

On rural land the zoning, septic and water answers often come before the building answer. Here is who decides each part in Kitsap County, 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 permit County building department

Kitsap County Department of Community Development (Permit Services)

For unincorporated land, Community Development accepts permit applications online only, through its Permit Application Portal, with fees, reviews and approved documents handled in a separate Online Permit Center. Several county divisions review each permit, and a new home needs a final inspection and occupancy approval. Cities inside the county, such as Bremerton, Port Orchard, Poulsbo and Bainbridge Island, issue their own permits.

Who decides the land use Rural and resource zones

Kitsap County Department of Community Development (zoning, Title 17)

County comprehensive plans set rural densities under the Growth Management Act, and the zoning code applies them parcel by parcel. Kitsap's Rural Residential zone allows one dwelling unit per five acres and is meant for low-density homes and farming consistent with rural character, on land relatively free of sensitive areas and with limited public services.

Sewer or septic Septic: local health jurisdiction

Kitsap Public Health District

For a new system, a licensed septic designer submits a Building Site Application to the health district, proposing the system and describing the water supply. Only after the district approves it does the owner get the building permit; a certified installer then obtains the installation permit, and occupancy follows approval of the new system.

Where the water comes from Private well

Proof of an adequate water supply comes before the permit. WRIA 15 covers the entire Kitsap Peninsula, and a new home on a new permit-exempt well in WRIA 15 is limited to an annual average of 950 gallons per day, pays a $500 fee with the building permit, and has the limit recorded on the title.

New well requirements
Kitsap Public Health inspects a well site before drilling and again during it, and approves the water supply only with the well log, a pump test showing at least five gallons per minute per residential connection, a bacteria test and a chemical test for iron, manganese, nitrate, chloride and conductivity, which the district calls the Kitsap 5.

Building on land near Kitsap County

Start with the zone and the soils. The Rural Residential zone's one-home-per-five-acres density decides whether a parcel can be divided, and the health district's septic review decides where the house can sit, because the drainfield and its reserve area must stay clear of buildings and parking. Much of the peninsula is wooded and cut by small streams draining to Puget Sound or Hood Canal, so clearing, driveway grades and the location of streams shape the site plan. Waterfront parcels add shoreline rules within 200 feet of the water. Budget time for the well: inspection, drilling, a pump test and water tests all come before the permit. For city lots on sewer, see Bremerton.

Building in Kitsap County: questions

Start the survey
How much does it cost to build a barndominium in Kitsap County?
On rural Kitsap land the site work can rival the shell: clearing timber, a long driveway, a new well with its testing, and a septic system designed for the soils. Waterfront or sloped parcels add more. We price against the actual parcel after a site visit. Sourced per-square-foot ranges and the main cost drivers are in our barndominium cost guide.
Do I need a building permit for a barndominium in Kitsap County?
Yes. A barndominium used as a home is permitted as a single-family residence. On unincorporated land, Kitsap County Community Development issues it through its online portal, and on a septic parcel the Kitsap Public Health District must approve the Building Site Application first. Inside Bremerton, Port Orchard, Poulsbo or Bainbridge Island, the city issues it. We manage the sequence through our permitting service.
Can I put a barndominium on five acres in Kitsap County?
Usually, if the parcel is zoned Rural Residential and the soils pass the septic evaluation. That zone allows one home per five acres and permits farming alongside it, which suits a pole barn home with stalls or an equipment bay. Other rural and resource zones have their own densities, so we check the county's zoning map for the parcel first.
What does the WRIA 15 well limit mean for a new home?
If the home will use a new permit-exempt well, the County collects a $500 fee with the building permit and records a withdrawal limit on the title, averaging 950 gallons per day in WRIA 15. Ecology's plan reads that as household use plus limited non-commercial lawn and garden watering. A parcel that can connect to a public water system avoids it.
