Kit homes are pre-cut, engineered house packages that ship to your lot and get built on a permanent foundation, just like a site-built house. The honest answer to “what are kit homes?” is that they’re a head start, not a finished house in a box. You get the framing, the shell, and the stamped plans as a labeled kit; you still handle the foundation, the trades, and the finish work. No sales pitch here, just the information you need to decide if a kit home fits your project in Idaho or Washington.
Below we’ll walk through what’s in the package, what kit homes cost, how the build runs, and how they stack up against modular and manufactured homes.
What are kit homes, really?
A kit home is a complete set of pre-cut, numbered building components that arrive together with engineered, stamped plans. Think of it like a large set of Lego pieces for a house: the parts are cut to fit, labeled, and sequenced so the crew isn’t measuring and cutting framing on site. That’s the core difference between kit homes and a traditional stick-built house, where the lumber shows up as raw material and gets cut piece by piece.
It helps to be clear about what a kit does and doesn’t include, because “kit homes” gets used loosely online. If you want the full breakdown, our guide on what a kit home is covers the package in detail. The short version: the kit is the shell and the structure, and you build it on a foundation you’ve already prepared.
What’s in the package (and what you still buy)
A typical kit home package covers the parts that are hard to get right on site: the framing, the exterior shell, the roof system, windows and exterior doors, and the engineered plans. What it usually doesn’t include is everything that has to connect to your specific lot and local code.
Here’s the honest split for most kit homes:
-
In the kit: pre-cut framing, exterior sheathing and siding, roofing components, exterior windows and doors, and stamped structural plans.
-
On your list: the foundation, site prep, plumbing, electrical, HVAC, insulation, drywall, flooring, cabinets, and final finishes.
The trades work is where local code matters most, so it’s handled by licensed pros to match Idaho or Washington requirements. If you’re weighing how much of this you can take on yourself, that’s a real question with a real answer, and it depends on your skills and your permit.
How much do kit homes cost?
The most common confusion with kit homes is treating the kit price as the finished-home price. They’re not the same number. The kit covers the shell and the structure. The finished cost adds your foundation, the trades, the finishes, and the site work, which vary by lot.
Because those add-ons depend on your specific site, we won’t quote a single figure here. What matters is reading a quote correctly: know what the kit covers, then price the rest separately so two quotes are comparable. Our breakdown of the total cost of a kit home walks through what’s inside a typical package price and what sits outside it.
How the build works
The sequence for kit homes looks a lot like any custom build, with one big shortcut: the parts are pre-cut, so framing goes faster and with fewer errors. Here’s the usual order:
-
Site prep and foundation. Your lot gets cleared and a foundation is poured before the kit arrives.
-
Delivery. The kit shows up as labeled, weatherproof packages, sequenced for the build.
-
Framing and shell. The pre-cut components go up quickly because nothing needs to be measured and cut from scratch.
-
Trades. Plumbing, electrical, and HVAC get roughed in, then insulation and drywall follow.
-
Finishes. Flooring, cabinets, fixtures, and paint bring it to move-in ready.
Are kit homes good quality?
Yes, when they’re built to code with quality components. The pre-cut approach doesn’t lower quality; if anything, factory-cut parts are more consistent than framing cut by hand on a windy job site. The insulation and windows in a kit home meet the same local energy code as a new stick-built house, so a well-built kit home performs like any new construction. The finished result is a permanent home on a foundation, not a temporary structure.
Kit homes vs. modular and manufactured homes
These three get mixed up constantly, and they finance and permit differently, so the distinction matters.
-
Kit homes: pre-cut parts shipped flat, built on-site on a permanent foundation. Permitted and financed like a site-built house.
-
Modular homes: built in finished sections at a factory, then trucked in and set on a foundation.
-
Manufactured homes: built entirely in a factory to a federal HUD code, often on a steel chassis, and financed differently.

Kit homes in Idaho and Washington
Kit homes fit the Inland Northwest well. They handle the local climate and snow loads when engineered for it, and they permit like any site-built home in the region. If you’re building around Spokane, Coeur d’Alene, Post Falls, or Boise, the local rules and process are worth reading up on before you buy. We cover the specifics in kit homes in Idaho and kit homes in Washington state.
FAQ
Are kit homes cheaper than a traditional house?
Often, but the savings come from specific places: less framing labor, less waste, and a faster build, not from cutting corners on materials. The kit price is lower than a comparable custom shell, and the finished cost still depends on your foundation, trades, and finishes.
Can I build a kit home myself?
You can take on some of it, especially the parts that don’t need a license, but plumbing, electrical, and HVAC go to licensed trades to meet code. Most owner-builders handle the general coordination and some finish work and hire out the rest.
How long does it take to build a kit home?
The shell goes up fast because the parts are pre-cut, but the full timeline depends on your foundation, trades, and finish schedule. It’s quicker than a fully custom stick-built house, though it’s still a real construction project, not an overnight job.
Do kit homes hold their value?
A kit home is a permanent home on a foundation, so it’s appraised and sold like any site-built house in the same area. Its value tracks the local market, not the fact that it started as a kit.
The bottom line
Kit homes give you a faster, more predictable path to a permanent house by shipping the shell as pre-cut, engineered parts. You still need a lot, a foundation, and the trades, but you skip a lot of the measuring, cutting, and waste of a traditional build.
