Barndominium Builders in Spokane Valley, Washington

Spokane Valley is its own city, incorporated separately from Spokane, with its own Permit Center, zoning code and comprehensive plan, so a parcel here never runs through Spokane's permit office. Most of the city is built out in subdivisions and commercial corridors, and the City is planning for thousands more housing units by 2046, which means a full-size barndominium with a shop bay usually needs one of the larger residential lots rather than a typical house lot. Buyers who want five acres or more generally end up in unincorporated Spokane County, where rural zoning and private wells take over. Inside the city, a pole barn home or a steel-framed living quarters is permitted like any new single-family house, with a site plan, construction plans and a copy of the sewer permit. Barndominium kits make sense if you plan to erect the shell yourself; if you would rather hand over the whole job, our turnkey builds cover site work through final inspection. Send us the parcel number and we will check its zoning, floodplain status and sewer availability before any drawings start.

Pole Barn Homes in Spokane Valley

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 Spokane Valley: 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 Spokane Valley, 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 City building department

City of Spokane Valley Permit Center

The City of Spokane Valley Permit Center issues residential building permits inside city limits, including new single-family homes and new garages or pole buildings. A new home application needs a site plan, construction plans and a copy of the sewer permit. Spokane Valley is a separate city from Spokane, so the City of Spokane's permit office does not handle land here.

Who decides the land use Inside an urban growth area

City of Spokane Valley Planning and Zoning Division

The City's Planning and Zoning Division administers Spokane Valley's zoning ordinance and subdivision code and maintains its comprehensive plan. The plan now being updated must accommodate 128,313 residents and 16,661 new housing units by 2046, so land inside the city is planned for growth rather than acreage living.

Sewer or septic Public sewer

Spokane County (sewer permits); Spokane Regional Health District for on-site systems

Spokane Valley's sewer is a Spokane County utility, and the City's permit checklist asks for a copy of the County sewer permit with the building application. Where no sewer reaches a lot, Spokane Regional Health District's Liquid Waste program permits and inspects the on-site septic system, working with local building and planning departments.

Where the water comes from Public water system

Local water and irrigation districts (varies by address)

The City does not run a water utility. Water in Spokane Valley comes from independent districts, and the property's location decides which one serves it; the City points owners to the County's map of water district service areas. All of the regional water purveyors belong to the Spokane Aquifer Joint Board. A lot beyond a district's mains would need its own well.

Pole buildings need engineered drawings
The City of Spokane Valley's residential permit checklist says that if the proposed construction is a pole building, engineered drawings are required, and one set must carry an original signature and stamp. Garages and pole buildings need a permit here just as a new house does.

Floodplain permit
Spokane Valley takes part in the National Flood Insurance Program and regulates floodplain development under chapter 21.30 of its municipal code. Any development on a parcel inside a FEMA special flood hazard area requires a separate Floodplain Permit from the City.

Building on land near Spokane Valley

Start with the utilities, because in Spokane Valley they are split among several providers. Confirm which water district serves the parcel and whether the County sewer line reaches it, since the building permit application needs the sewer permit in hand. Then check the FEMA flood map, as land in a special flood hazard area adds a floodplain permit. A post-frame or steel building of real size usually fits only the larger residential lots, and the pole-building rule means paying for stamped engineering. Slopes of 30 percent or more are treated as geologically hazardous under the City's critical areas rules. Outside the urban growth area, Spokane County says minimum lot sizes generally run 5 acres or larger, so for acreage, a private well and room for a big shop, look at unincorporated Spokane County instead.

Building in Spokane Valley: questions

Start the survey
How much does it cost to build a barndominium in Spokane Valley?
The building is only part of it. In Spokane Valley the site adds its own line items: the County sewer connection, stamped engineering if the frame is a pole building, any floodplain work, and the district's water hookup. Each of those depends on the exact parcel, so a real number comes after we see it. For sourced per-square-foot ranges and the main cost drivers, read our barndominium cost guide.
Do I need a building permit for a barndominium in Spokane Valley?
Yes. The City of Spokane Valley Permit Center issues the permit for any new single-family home, and it lists new garages and pole buildings among the projects that need one too. Spokane Valley is not part of the City of Spokane, so the application goes to the Spokane Valley Permit Center, not to Spokane's. Our permitting service gathers the permit paperwork, including the sewer forms.
Is there acreage for a barndominium in Spokane Valley?
Not much. The city is mostly subdivisions and commercial corridors on public sewer, and its comprehensive plan is aimed at adding housing units rather than rural lots. Owners who want several acres, horses or a large detached shop usually buy in unincorporated Spokane County, where rural zoning, a private well and a septic system are the norm.
Who supplies water to a new home in Spokane Valley?
It depends on the address. The City has no water utility of its own; independent water and irrigation districts serve different parts of the valley, and the City sends owners to the County map of their service areas. Before buying, confirm the district, its connection requirements and whether a main reaches the lot.
