Barndominium kits

Barndominium kits in Idaho: kit, shell or turnkey

Most people who look for a barndominium in Idaho start with a kit. A barndominium kit is the structural package: an engineered steel or pole barn (post-frame) frame, the roof and wall panels, trim, fasteners and the doors the package names. It is delivered to your land and put up on a slab or foundation there. You can buy the kit and build it yourself, have us put it up to a dried-in shell, or have us build the whole home.

Prefab, modular and manufactured are words people use for the same idea, but they are not the same thing. A kit is prefabricated in the sense that its parts are cut and made in a factory, but the house is assembled and finished on your land. A modular home arrives as finished boxes built in a factory, and a manufactured home is built whole in a factory to the federal HUD code and set on site. What we sell and build are kits and site-built barndominiums; the barndominium kits page sets out what each option includes and what it leaves out.

The engineered frame, roof and wall panels, trim, fasteners and the doors the package names, delivered to your land for you or your own crew to put up.

Dried-in shell

We pour the slab and put the kit up to a weather-tight shell, and you finish the inside yourself or with your own trades.

Turnkey build

The whole project from bare land to keys: site work, slab, shell and finished interior, with one point of contact throughout.

Pole barn homes and kits

A pole barn home is a house built on a pole barn frame: large posts set wide apart carry the roof, so the inside is open to lay out however you like, with room for a shop bay or equipment under the same roof. Pole building, pole barn and post-frame all describe the same way of framing. We supply pole barn home kits and build pole barn homes to the shell or to the keys, with the frame sized to the snow load set for your site by the local building official or the engineer on the project.

Barndominium floor plans

Start from one of our barndominium floor plans and change it, or have a plan drawn from scratch around your land, your shop and the way you live. Either way the plan is fitted to the parcel: where the septic system and well can go, which way the lot drains, and what the county setbacks allow.

Thinking small? A small barndominium is often the fastest route onto your land, and the size-for-budget guide walks through how the footprint and the budget trade against each other.

Cost guide

How much does it cost to build a barndominium in Idaho?

We do not publish a price list, because on an Idaho barndominium the land moves the number more than the floor plan does: the driveway, the pad, how far power has to run, a well and a septic system, the snow load the frame is sized for, and what the planning and building offices ask for. The cost guide sets out published third-party cost data, every figure with its source, with a calculator built on those same cited ranges, and walks through what pushes a build to the top or bottom of the range.

How a build runs

Land to keys, in four stages

In Idaho, barndominium projects go wrong early, at zoning, septic, water and site checks, long before anyone pours concrete. Here is the order we work in and why.

Start your plans

Start the survey. We take your program, the rooms, the shop bay, how you actually want to live in it, and start a floor plan drawn for your land rather than pulled off a shelf, whether you bring a sketch, a saved layout or a blank sheet. This is where most of the useful decisions get made.

That is how a build runs. Step one is a plan drawn for your land, and that starts with the survey.

Building a barndominium in Idaho

Four things shape an Idaho build before anyone pours concrete, and the first of them is which office, if any, reviews and inspects the house where your land is.

Who issues the permit

Idaho homes are built to the Idaho Residential Code, but Idaho leaves enforcement to cities and counties: one that issues building permits must use the state-adopted codes, and some rural counties do not run a residential building-permit program at all. Where there is none, there is no local building permit or inspection, but electrical, plumbing and HVAC work still needs permits and inspections, and zoning, septic and well rules still apply. We confirm which case your parcel is in first.

How we handle permitting

Snow load is set for your site

Idaho snow loads vary sharply with elevation. The University of Idaho's Ground Snow Loads for Idaho study is the common reference, but the design snow load for your lot is set by the local building official or the engineer on the project, and frost depth is set locally too. The frame is sized to the figures for your site, which is why a kit is quoted for the address it is going to.

Pole barn homes

Septic and well on rural land

Off city sewer and water, the parcel needs a septic system and usually a well. Every septic system in Idaho needs an installation permit, and site evaluations, permits and inspections are handled by the public health district for your county. A single-home well does not need a water-right permit in most of Idaho, but it does need a drilling permit from the Department of Water Resources and a licensed well driller. We check both early, because the septic site can decide where the house goes.

Site preparation

Zoning, water and the land

Every Idaho county zones its unincorporated land, even where it does not issue building permits, so zoning decides whether a home is allowed on the parcel. In irrigated country, ditches and canals carry a legal right-of-way: you cannot build, fence or landscape in it without the ditch owner's written permission. We check both before the house is sited.

Are barndominiums legal in Idaho?

Barndominium builders across Idaho

Looking for barndominium builders near you? We build in seven regions of Idaho, from Boise and the Treasure Valley to the Magic Valley, Pocatello, Idaho Falls and the Panhandle. Inside Boise, Meridian, Nampa and the other larger cities most land is already subdivided, so most of our work is on rural and edge-of-town parcels in the counties around them. Zoning, building permits and septic approvals sit with different offices from one county to the next, so every project starts with the parcel.

Building in Idaho: common questions

18 questions we get asked most often about building in Idaho. If yours is not on the list, ask it directly.

Start the survey
Do you build barndominiums across Idaho?
Yes. Idaho Barndominium Builders builds barndominiums, pole barn homes and metal building homes on private land across Idaho: Boise, Meridian, Nampa, Caldwell, Eagle, Kuna, Star, Middleton and Emmett in the Treasure Valley; Mountain Home and McCall in Southwest Idaho; Coeur d'Alene, Post Falls, Hayden, Rathdrum and Sandpoint in the Panhandle; Lewiston and Moscow in North-Central Idaho; Twin Falls, Jerome, Burley and Hailey in the Magic Valley; Pocatello, Chubbuck and Blackfoot in Southeast Idaho; and Idaho Falls, Ammon, Rexburg and Rigby in Eastern Idaho, along with the rural counties around them. See the areas we serve, or start the survey with your parcel.
Do you build on land I already own?
Yes, and that is most of the work: rural acreage, family land and edge-of-town lots. We check what the zoning allows, walk the property with you, check access for concrete trucks and delivery equipment, and work out where power, water and a septic system can go. If you have not bought land yet, look at it with us before you close: whether the county allows a new home there, where a septic system can go and how water reaches the parcel are questions to answer before the purchase, not after. Tell us where it is in the survey.
Do you sell barndominium kits in Idaho, or only full builds?
Both. You can buy a barndominium kit and put it up yourself or with your own crew, buy a dried-in shell and finish the inside yourself, or hand us the whole project from bare land to keys as a turnkey build. Plumbing, electrical and HVAC go to licensed trade contractors whichever route you take. Most people know which fits once they have looked honestly at their time, their budget and who they have available to build. Tell us which way you are leaning in the survey.
Are barndominium kits the same as modular, prefab or manufactured homes?
No, though the words get used for the same idea. A barndominium kit is a package of engineered frame, roof and wall panels, trim and doors that is delivered to your land and put up on a slab or foundation there; its parts are made in a factory, so it is prefab in that sense, but the house is assembled and finished on site. A modular home arrives as finished sections built in a factory. A manufactured home is built whole in a factory to the federal HUD code and set on site. What we sell and build are kits and site-built barndominiums. The barndominium kits page sets out what a kit includes and what it leaves out.
What is the difference between a barndominium, a pole barn home and a metal building home?
Barndominium describes what the building is: a home, usually open-plan and often with a shop or garage bay under the same roof. A pole barn home (the engineering term is post-frame) is built on a wood frame of large posts, spaced wide apart, that carry the roof and wall loads, with girts and purlins running between them. A metal building home is framed in steel instead. Inside, any of them is finished like a conventional house. We build both pole barn and steel-frame barndominiums.
How much does it cost to build a barndominium in Idaho?
We do not publish a price list, because on a barndominium the land moves the number more than the floor plan does: the driveway, the pad, how far power has to run, whether the parcel needs a well and a septic system, the snow load the frame has to carry, and what the county and building department ask for. Our barndominium cost guide sets out published third-party cost data with its sources, and its calculator uses only those cited ranges. For a number against your own parcel, start the survey and we will put a written quote in front of you before anything is ordered.
Is a barndominium cheaper to build than a traditional house?
Sometimes, but not automatically. A pole barn or metal building shell spans wide without interior load-bearing walls, but a barndominium is finished inside like any house, and insulation, drywall, cabinets, flooring, plumbing, electrical and HVAC cost much the same whatever frame they sit in. The land work (driveway, pad, power, well and septic) often decides the comparison. Our barndominium vs. house cost guide sets the two side by side with cited data.
Do I need a building permit for a barndominium in Idaho?
It depends on where the land is. Idaho's residential building code is the Idaho Residential Code, the 2018 International Residential Code as adopted and amended by the Idaho Building Code Board. Idaho leaves enforcement to cities and counties: a city or county that issues building permits must use the state-adopted codes (Idaho Code §39-4116), and building there without its permit is unlawful. Some rural counties do not run a residential building-permit program at all. Where a county has no building program, there is no local building permit or building inspection, but electrical, plumbing and HVAC work still needs permits and inspections, and zoning, septic and well rules still apply. The state Division of Occupational and Professional Licenses (DOPL) handles those trade permits where no local program does; it does not act as the building department for private homes. Ask the county planning and zoning office, or the city inside city limits, whether it issues residential building permits before you buy land. We work through that sequence as part of permitting.
Can a barndominium be built as an agricultural building to avoid the code?
No. Idaho exempts barns and other agricultural buildings from the building code, but the exemption expressly excludes any space used for living, sleeping or cooking (Idaho Code §39-4116(5)). A barndominium is a home, so it is built and permitted as a house, even when a shop or equipment bay shares the roof. Are barndominiums legal in Idaho? covers the detail.
Who approves the septic system and the well?
Every septic system in Idaho needs an installation permit. Site evaluations, permits and inspections are handled by the public health district for your county, under the Department of Environmental Quality's septic rules (IDAPA 58.01.03), and the system is installed by an installer holding a state installer permit. A single-home well does not need a water-right permit in most of Idaho (Idaho Code §42-227), but it does need a drilling permit from the Idaho Department of Water Resources before construction and a licensed well driller (Idaho Code §42-235). New subdivisions of five or more lots in some ground-water management areas are treated differently, so check if you are buying into one. We do not design or install septic systems or drill wells; we check both early, because the septic site evaluation can decide where the house goes. See site preparation.
How much snow does a barndominium roof have to carry in Idaho?
There is no single Idaho figure. Idaho snow loads vary sharply with elevation. The University of Idaho's Ground Snow Loads for Idaho study is the common reference, but the design snow load for your lot is set by the local building official or the engineer on the project, and frost depth and other design criteria are set locally too. The frame of a pole barn home or a steel building is sized to the figures for your site, and insulation and window requirements follow the Idaho Energy Conservation Code, based on the 2018 IECC, for your climate zone.
What should I check on rural land before I buy it?
Start with zoning: every Idaho county zones its unincorporated land, even where it does not issue building permits, so the county planning and zoning office can tell you whether a home is allowed on the parcel. Then look for water on the ground. Irrigation ditches and canals carry a legal right-of-way, and you cannot build, fence or landscape in it without the ditch owner's written permission (Idaho Code §42-1102). Idaho's right-to-farm law protects established farms from nuisance claims by new neighbours, so a working farm next door stays one. Where the septic system and well can go, access, and how far power has to run finish the picture. Tell us about the parcel in the survey.
How do I check a barndominium builder in Idaho?
Idaho requires construction contractors to register with the Idaho Contractors Board, part of the Division of Occupational and Professional Licenses (Idaho Code §54-5204); Idaho registers contractors rather than licensing them. Before you sign, you can check a builder's registration on DOPL's license search. On residential contracts over $2,000, Idaho law requires the general contractor to give you a written disclosure of your rights, including lien waivers, proof of insurance and the option of a surety bond (Idaho Code §45-525). An owner building on their own residential property is exempt from registration, which is one reason a kit is a real option for owner-builders.
Can I build a small barndominium?
Yes. A small barndominium, a single-storey home with or without a shop bay, is often the quickest way onto your land, and the same kit, shell or turnkey options apply. The permits, septic system, well and site work do not shrink in proportion to the floor area, so the cost per square foot of a small home tends to run higher than a large one. Our size-for-budget guide and the floor plans show how the footprint and the budget trade off.
Can you build a shop house, with living space and a shop under one roof?
Yes. A shop house, or shouse, puts a working shop or equipment bay and the living space under one roof, and it is one of the most common reasons people choose a barndominium. The shop door size, the ceiling height in the bay and how the living space is separated from it are the decisions that shape the plan. If you might add a bay or a wing later, say so at the start: sizing the slab, leaving a gable end clear and running enough electrical capacity now makes that far simpler.
Can I finance a barndominium like a normal house?
Often, but not with every lender. Some treat a barndominium as ordinary residential construction; others are less familiar with it, and the appraisal is where that tends to show. We can provide the plans, specifications and cost breakdown a lender asks for during approval and the construction draw process. Our barndominium financing guide walks through the options.
Who handles plumbing, electrical and HVAC?
Licensed trade contractors handle plumbing, electrical and HVAC. On a turnkey build we schedule that work as part of the project, so you deal with one point of contact from the first drawing to the final walkthrough rather than a chain of separate contractors.
How do I get started?
Start the survey. It asks where the land is, what you want to build, roughly how big, how you want to buy it (kit, shell or turnkey) and when. That is enough for us to come back with the questions that matter for your parcel, starting with what its zoning allows. There is no charge for that conversation.
