Custom Shop Builds in Teton Valley + Jackson Hole — Fixed-Price by a 20-Year Builder
If you own a lot in Driggs, Victor, Alta, or across the pass in Jackson and you want a real shop, not a metal kit dropped on gravel, this is the page. SwagerBuilds LLC is a 4th-generation Rigby builder running fixed-price contracts, no allowances, and a JobTread client portal so you can see the budget and schedule in real time. Twenty years of general contracting in this valley. I build detached shops, pole barns, RV storage, and shops with living quarters upstairs. If you already have a lot picked out, or you’re still deciding between a shop-first or house-first build, start here.
Shops need engineered stamps. Ours are already on speed dial.
Foundation, roof — especially in Teton snow-load country where 100+ psf is real — every shop needs a structural engineer stamp. After 20 years, we’ve got a network of engineers who take our calls first. That means stamps on schedule, revised calcs in days when the reviewer red-lines something, and no scrambling to find someone new mid-permit.
Types of Shops We Build
Detached Shop
Standalone workshop, home business space, or hobby shop on its own footprint. Common footprint in the valley is 30×40 up to 50×80. Concrete slab, insulation package, and door count are the three levers that move the price. If you want it wired for a lift, welder, or 240V compressor, we spec that in the contract, not on a change order later.
Pole Barn / Post-Frame Shop
Post-frame construction is the cost-efficient path when you need large clear spans and don’t need a fully finished interior. Good for equipment storage, ag use, and cold-storage barns. You can still insulate and heat later. I build post-frame with real engineered trusses and proper concrete piers, not screw-in ground anchors.
RV Shop / Toy Barn
14-foot doors minimum for a Class A motorhome, 16-foot if you want a fifth-wheel with the AC on top. Common Jackson use case: boat, side-by-sides, snowmobiles, and a truck under one roof. If you want a wash bay with a drain, that’s a permit conversation we handle upfront.
Shop with Living Quarters
Main-floor shop with an apartment or ADU upstairs. Popular for out-of-state owners building the shop first while the main house is in design, or for a family member, caretaker, or rental. Teton County ID and Teton County WY handle this differently. I walk you through the variance path on the site walk.
Heated / Insulated Shop
If you’re using the shop November through April, in-floor radiant is the answer. Spray foam or batt+rigid on the walls, closed-cell in the roof. I’ve built shops here where the owner runs a single small boiler and holds 55 degrees all winter for under $200 a month in propane. Slab prep matters more than the boiler.
Shop with Loft or Mezzanine
Extra square footage without extending the footprint. Good for office space, gear storage, or a guest bunk area that doesn’t trigger full ADU permit review. Loft height and stair egress are code items we lock in before you sign the fixed-price contract.
What This Costs
Straight answer: real range depends on site work, finish level, door count, insulation package, and permit path. Your Teton Valley lot with clean access and existing power is a different number than a Jackson hillside lot with a 400-foot driveway and a well. On your /start/ intake, you get a fixed-price quote in 5-10 days. No allowances. No “TBD” line items. No calls two months in about “the concrete came in higher than we thought.”
If you want a rough gut-check before intake, we’ve seen recent TV+Jackson shops land in a wide per-square-foot range depending on whether it’s a bare post-frame or a fully-finished heated shop with living quarters upstairs. [VERIFY WITH BRYCE — specific $/sf range to publish]
The contract you sign is the price you pay. If something changes, it’s because you asked for it, and you see the impact in the JobTread portal before you approve.
Why a 20-Year GC
Twenty years of building in Teton Valley and across the pass in Jackson means I know which subs show up when it’s 12 degrees and pouring, and which ones ghost you in November. I know the Teton County ID building department by first name and I know the Teton County WY permit tempo well enough to schedule around it. Snow load on the Idaho side runs high, higher yet on the Wyoming side above the valley floor, and the trusses get engineered accordingly, not copy-pasted from a Utah plan set.
Cold-weather concrete is its own thing. Frost walls, insulated blankets, heated slabs, mix design in November. Get it wrong and you’re chipping out a slab in April. Mountain-lot site work means real geotech, real drainage, and a driveway that survives runoff. Twenty years means I’ve made the mistakes on my own dime already so you don’t pay for them on yours.
The concrete under a great shop matters. For shop foundations, flatwork, epoxy floors, and stamped-concrete aprons, we partner with Skinner Custom Concrete — Zach Skinner’s crew installs foam monoslab foundations that shave weeks off shop-build timelines vs. a traditional stem-wall dig, and their epoxy garage floors are built for Idaho winters. Same regional coverage: Teton Valley, Jackson Hole, Rigby, Rexburg, Idaho Falls, and Island Park.
The Fixed-Price Process
Every SwagerBuilds shop follows the same path. You start on /start/ with a short intake, a few lot photos, and rough scope. I do a site walk, usually within a week if you’re in TV or Jackson. From there I write a fixed-price contract with the full scope line-itemed. No allowances hidden in the fine print. Once you sign, you get JobTread portal access, budget, schedule, weekly updates, photo logs, and every change order visible in one place. Weekly video or phone check-ins if you’re remote. Final walk, punch, done.

Remote-Owner Friendly
Roughly half of the shops I build are for owners who don’t live here full time. Salt Lake, Denver, the Bay Area, Seattle. The JobTread portal was built for exactly this. You see the budget line items, the current schedule, the photo log from Tuesday’s pour, and every change order in one dashboard, from your phone. I do weekly video walks so you’re not guessing. Selections, subs, inspections, all managed from here. You show up for the final walk and it looks like the renderings.

Where We Build
- Driggs, ID — home base for most Teton Valley shop and ADU work
- Victor, ID — south valley builds, common for owners commuting over the pass
- Alta, WY — the Wyoming side of the valley, Teton County WY permit path
- Tetonia, ID — north valley, larger ag lots, common pole barn territory
- Jackson, WY — over Teton Pass, heavier permit tempo, plan for a longer runway
- Wilson, WY — west of Jackson, tight lot access on some parcels
- Teton Village, WY — resort-adjacent, HOA and design review usually in play
- Rigby, ID — hometown work is allowed, this is where my family has built for four generations
- Rexburg, ID — same, hometown work welcome, and most jobs bridge to a TV or Jackson build
FAQ
How long does it take to build a 40×60 detached shop in Teton Valley?
From signed contract to keys, plan on 4-6 months for a standard 40×60 detached shop with a concrete slab, insulation, two overhead doors, and basic electrical. That assumes permits move at normal tempo (Teton County ID is currently 4-8 weeks depending on scope) and we start dirt in a workable weather window. Winter starts can add a month for frost work. If you’re adding living quarters upstairs or a wash bay, add 6-10 weeks. The fixed-price contract you sign has the actual schedule locked in.
Do I need a variance for a shop-with-living in Teton County ID?
Sometimes yes, sometimes no. It depends on your zoning district, lot size, and whether the living portion qualifies as an ADU under current Teton County ID code. On the site walk I flag the permit path and, if a variance is needed, we build the timeline around the hearing schedule. Teton County WY (Jackson side) has a different set of rules. Either way, you get the honest answer on the site walk, not after you’ve signed.
What snow load do you build to?
Teton Valley floor is typically 70-80 psf ground snow load, which converts to a specific roof design load through the structural engineer. Higher elevations, up in Alta or above the valley floor in Jackson, can go significantly higher. I don’t guess. Every shop I build gets stamped truss engineering for your specific parcel. If somebody quotes you a shop without pulling site-specific snow numbers, that’s a red flag.
Do you handle the concrete slab or is that separate?
Included. The slab, the frost walls, the site prep to get there, all in the fixed-price contract. I don’t do the “shop kit here, find your own concrete guy” split. That’s how you end up with a slab that doesn’t match the anchor bolt layout and a $12k change order in month two. One contract, one price, one point of accountability.
Can I finance the shop separately from a home build?
Yes. Plenty of clients finance the shop on a construction loan or cash-pay it, then build the main house on a separate loan a year or two later. I’ve worked with most of the local and regional lenders that do rural construction lending in ID and WY. On the intake, tell me which lender you’re talking to and I’ll tell you what they usually need from me for the draw schedule.
What’s the difference between a pole barn and a stick-frame shop?
Pole barn (post-frame) uses engineered posts embedded in concrete piers with trusses spanning between them. Fewer pieces, faster to dry-in, cheaper per square foot for large open spans. Stick-frame is conventional 2×6 wall framing on a foundation, easier to fully insulate and finish, better for shop-with-living or heavily finished interiors. If your goal is 60 feet of clear span with no interior walls, post-frame. If your goal is a heated finished shop with an apartment upstairs, stick-frame usually wins.
Do you build across the state line in Jackson?
Yes. Roughly a third of my current backlog is in Teton County WY. Jackson permits move slower than the Idaho side and design review is usually in play, so I build that into the schedule from day one. The fixed-price contract, the JobTread portal, the process, all the same on both sides of the pass.
