Shop Houses (Shouses) in Idaho

A shouse, or shop house, puts a working shop and a home under one roof: a heated bay for the truck, the camper, the tractor or the business, with the living space beside it or above it. We design and build shop houses in Idaho on steel or pole barn frames. Because the building contains a dwelling, the whole of it is treated as a house under the Idaho residential code wherever a city or county runs a building program, and the shop has to be separated from the living space the way the code requires for any attached garage.

Where a Shop House Fits on Idaho Land

Shop houses make the most sense where there is room for them: acreage in the rural parts of Ada and Canyon counties, the farm ground of the Magic Valley, the upper Snake River plain and the timbered parcels of the Panhandle. On a subdivision lot inside a city, covenants and zoning often limit building size, height, door placement or metal siding, so check the plat and the zoning code before you fall for a 60-foot shop.

Two Idaho details shape the plan. The first is winter: a heated shop with a floor drain, and a mudroom between shop and house, earn their keep every day of a long winter. The second is water on the land. Much of the Treasure Valley and Magic Valley is crossed by irrigation ditches and laterals, and state law says no one may put a road, fence, utility line or structure in a ditch right-of-way without the written permission of the ditch's owner or operator. A big shop and its apron need to sit clear of them.

If the shop will run a business, with employees or customers, ask the planning office early. A hobby shop with a home is one question; a home business with traffic is another, and the zoning code decides whether that use is allowed where you are building.

Shouses: how the work runs

Four stages, in this order. The sequence matters more than it looks: settling the zoning, the septic site evaluation, the snow load and the building permit before anything is fabricated is what keeps an Idaho build from stalling.

1

Zoning and use of the shop

Start with the parcel's zoning, any subdivision covenants, and what the shop will be used for. The county or city planning office decides whether a large accessory building, a home business or a second structure is allowed where you are building.

2

Layout and separation

Bay sizes, door heights, the living space and where the two meet. The wall, floor or ceiling between shop and house has to meet the residential code's separation requirements, and the plan places it so the separation does not fight the layout.

3

Frame, shell and services

A steel or pole barn frame sized to the snow load for your site, then the shell, insulation and services. The shop may need its own heat, a floor drain or a larger electrical service, all installed by licensed trade contractors.

4

Inspection and finish

Where a building department serves the land it inspects the whole building under the residential code, shop included. Finishes in the living space, and the shop floor, drains and lighting in the bays, complete it.

A heated shop is worth more in an Idaho winter

Idaho's climate swings hard between seasons, with cold winters and, at higher elevations in the north and centre, up to four times the snow of the southern plains. A shop you can work in through January, a floor drain for the meltwater off the truck, and a mudroom that keeps the snow out of the house are the details owners tell us they would not do without.

Where we deliver shouses

In Idaho the line that matters is usually a city limit. Inside one, the city zones the land and, where it runs a building program, issues the permit. Outside one, the county zones the land and, if it runs a building program, permits and inspects the house. What changes from place to place is the zoning, the snow load and frost depth the local building department sets, which of the seven public health districts evaluates and permits the septic system, and whether irrigation ditches cross the parcel.

What actually decides the price

Square footage is the number everyone leads with, and it is rarely the one that moves a barndominium budget. These four do.

  • Shop door size and count

    A 14-foot or 16-foot overhead door for a camper or equipment needs a framed opening that changes the wall design, and a door in a gable end changes the end frame. More and bigger doors move the price more than floor area does.

  • Heated or cold shop

    A heated shop needs the same insulated envelope as the house, a vapour retarder and a heat source. A cold shop is cheaper to build but still needs the code-required separation from the living space.

  • Span and snow load

    A column-free shop floor under a heavy snow load needs deeper rafters or trusses. The building department sets the ground snow load for your site, and the wider the shop, the more it matters.

  • Floor, drains and slab

    A thicker slab for heavy equipment, trench or floor drains and in-floor heat are common shop-house upgrades. Where a floor drain goes, and where its water ends up, needs settling with the building department before the slab is poured.

Shouses in Idaho: common questions

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

What is a shouse?
A shop house: one building with a working shop and a home under the same roof. The shop might hold vehicles, a camper, equipment or a business; the living space sits beside or above it. In Idaho the whole building is a dwelling once it contains a place to live, sleep or cook.
Does the shop part of a shop house need to meet the residential code?
Where your city or county runs a building program, the whole building is permitted and inspected as a dwelling under the Idaho residential code, shop included. The code also requires a separation between the shop and the living space, like any attached garage.
Can I run a business out of the shop?
It depends on the zoning where you are building. Many rural and residential zones allow some home occupations and limit others, especially those with employees, customers or signs. Ask the county or city planning office before you design the shop around a business.
How big can a shop house be in a subdivision?
That is set by the zoning code and often by subdivision covenants, which can limit building size, height, siding materials and where large doors may face. Check both before buying the lot or drawing the plan.
Steel or pole barn frame for a shop house?
Both work. A steel frame suits very wide, column-free shop bays and tall doors. A pole barn frame is often cheaper on moderate spans. The snow load for your site sizes either one.
Can the living space be above the shop?
Yes, and it saves footprint, but it makes the separation between shop and house a floor-ceiling assembly, adds stairs and puts bedrooms over the working space. A side-by-side layout with a mudroom between is simpler to build.
What about irrigation ditches on my land?
Many Idaho parcels are crossed by irrigation ditches and laterals. State law bars any structure, fence, road or utility line in a ditch right-of-way without the written permission of the ditch's owner or operator, so we locate them before siting the shop and its apron.
What does a shop house cost?
We do not publish prices, because the shop doors, span, snow load and how much of the building is heated move the number more than square footage. Our cost guide gives sourced finished-cost figures, and the survey is the way to get a figure for your building.
