Custom Home Builder in Jackson Hole, Wyoming

Teton Valley builder serving Jackson Hole. Mountain modern, traditional ranch, alpine and trophy custom homes across Teton County, WY. Idaho + Wyoming licensed, 20-year builder.

I’m Bryce Swager — 20-year Rigby, Idaho custom home builder, serving the Jackson Hole side of the Tetons for years now. If you’re a Jackson Hole landowner (or shopping for a lot) and looking for a custom home builder who understands both sides of the pass, you’re in the right place. Our shop is based in Rigby, Idaho — 30 to 45 minutes from most Jackson job sites depending on route — with a licensed Wyoming footprint on the Teton County side. Teton Valley builder serving Jackson Hole is how most clients describe the working relationship.

The Jackson Hole custom home market in 2026

Jackson Hole (Teton County, Wyoming) is one of the most constrained luxury custom home markets in the American West. The county limits growth by ordinance and geography: 97% of Teton County WY is federal land — Grand Teton National Park, Bridger-Teton National Forest, National Elk Refuge, and the John D. Rockefeller Jr. Memorial Parkway. That leaves roughly 3% of the county available for private development, and buyers with high budgets chasing thin inventory.

The visual language of new custom construction here is dominated by mountain modern (steel, glass, board-form concrete, standing seam metal, timber accents), traditional Jackson Hole ranch, and — in the alpine subdivisions — Alpine-inspired cabin builds. Jackson-side work sits at the top of what we build, and trophy projects there are quoted per project.

Why a Teton Valley builder for a Jackson Hole custom home

  • Lower overhead. Jackson-side builders carry Jackson-side rent, Jackson-side wages, and Jackson-side insurance. Every one of those costs gets rolled into their per-hour rate and their GC fee. Our shop overhead is Rigby, Idaho — which meaningfully compresses the total-cost delta on equivalent scope and finish.
  • Sub bench in both states. Wyoming doesn’t have a state general contractor license, but we hold what Teton County WY requires and pull from a vetted subcontractor pool that includes Wyoming-registered plumbers, electricians, HVAC, roofers, and mechanical trades. We’re not asking Idaho subs to figure out Jackson code on the fly.
  • Real Teton experience. Snow load, wildland-urban interface fire code, wildlife setbacks, HOA and TVAC design guidelines — we’ve navigated all of these on active jobs.
  • Owner accessible. On every Jackson Hole custom home we build, I’m on site regularly and directly reachable by the client. Not a project manager two layers removed.
  • Design-first. We don’t quote custom Jackson-side homes before design is done. Fixed construction contract prices land only after a signed design agreement.

The Jackson Hole custom home process

1. Discovery + design agreement (weeks 1–16)

Before you’re committed to construction, we walk the lot with you, review any existing survey/soils/design work, and sign a design agreement that locks scope, delivers a preliminary construction budget in the schematic phase, and reserves your build slot on our calendar. Jackson lots have real quirks — wetland setbacks, elk migration corridors, wildland-urban interface (WUI) fire code overlays, HOA restrictions — that can add hundreds of thousands to the build if they surprise you at permit review instead of at design.

2. Design coordination (parallel with design agreement)

Most Jackson Hole clients bring their own residential designer or licensed Wyoming architect to the project. We coordinate closely with them on constructability, budget alignment, and value engineering as the drawings develop. If you don’t have a designer, we can recommend Wyoming and Idaho residential designers we’ve worked with successfully.

3. Permit + HOA/design review

Teton County, WY building permits go through the county’s SmartGov online portal, and new residential construction requires a scheduled submission week through the permit tech — you don’t just walk in and drop plans. Teton County adopted the 2024 IRC and IBC on 2/1/2025 for all permits submitted from that point forward. Homes over 2,500 SF trigger the Energy Mitigation Program per the 2026 fee schedule: $4/SF between 2,501–5,000 SF and $8/SF above 5,000 SF, with credits for PV, super-insulated envelopes, and passive design. In subdivisions with an architectural review committee (Shooting Star, Granite Ridge, 3 Creek Ranch, Crescent H Ranch, Indian Springs Ranch, Snake River Sporting Club, and others), plans also go through committee review before or in parallel with county submission. Full details are on the Teton County WY Building Division page.

4. Site work + foundation

Jackson-area soils vary from good river-bottom gravel to challenging clay and glacial till. Every custom foundation gets an engineered footing design based on the soils report. On concrete-heavy foundations and architectural flatwork we frequently partner with Skinner Customs for board-form and specialty concrete work.

5. Framing, envelope, mechanical

Snow load in most of Teton County WY runs 80–100 psf for ground snow load depending on elevation and location, driving heavier trusses, deeper roof structure, and — in exposed subdivisions — additional seismic and wind bracing. Teton County WY design criteria per the county Design Criteria page also specify Wind 105 mph, Seismic Design Category D, frost depth 34 inches, winter design temperature -30°F, and Climate Zone 7/8 requiring R-60 ceilings and R-20+5 walls. Envelope gets triple-pane, thermally broken windows and standing-seam metal roofing on nearly every custom.

6. Interior finish + closeout

Full-custom Jackson homes typically run 20–24 months foundation-to-CO because of winter shutdowns and finish complexity. We hold to the schedule with weekly client-facing updates through the JobTread project portal.

2026 construction cost for a Jackson Hole custom home

New custom home construction on the Jackson side runs $1,000 per square foot and up — construction cost, interior living space, with trophy Village and Wilson-adjacent builds quoted per project. Worked project budgets and the build-vs-buy math are in the 2026 Jackson Hole cost guide. The same specification costs materially more on the Jackson side, driven by:

  • Higher land, tighter design review committees, and layered HOA design guidelines
  • Teton County WY Energy Mitigation Program fees on homes over 2,500 SF
  • A smaller labor pool that commands a premium
  • Winter/snow logistics and staging premium
  • Higher snow load structural cost

How far up it goes depends on the finishes and fixtures you choose, and that’s your call to make. Once design and selections are set, your price is fixed.

interior living space — IECC definition

Conditioned SF means enclosed heated living space per the International Energy Conservation Code. It excludes unheated garage, unfinished basement, and unheated attic. It includes heated garage or heated basement when they are part of the conditioned envelope.

Estimate only. The figures on this page are for early planning. SwagerBuilds fixes a project price only after a signed design agreement locks scope, finishes, and site conditions. See custom home design services for how the design agreement phase works.

All-in project cost (land improvements, soft costs, design fee, contingency, financing carry) typically adds another 35–50% on top of construction cost. Land is separate and drives project total independently — Jackson-side lots that make sense for a custom home routinely run $1.5M to $8M+ before you break ground, and premium ski-in / trophy parcels push well above that.

Sample Jackson Hole project types we build

Mountain modern

Steel and glass exteriors, board-form concrete, wide expanses of triple-pane glass, standing seam metal, timber accents. Open great room, wide-plank site-finished hardwood, chef’s kitchen with commercial-grade appliance package. Snowmelt driveway and entry walk. Typical spec: 4,500–6,000 SF conditioned, 4–5 bed, 4.5–6 bath, 3-car garage with dedicated ski/gear room.

Traditional Jackson ranch

Stone and timber exterior, cedar-shake or standing seam roof, deep covered porches, oversized great room with double-sided fireplace. Traditional trim package, painted white oak or knotty alder millwork. Typical spec: 4,000–5,500 SF conditioned, 4–5 bed, single-level or main-level primary.

Ski cabin / alpine custom

Compact footprint (2,500–4,000 SF conditioned), premium finish, engineered for high snow load and quick close/open transitions if used as a second home. Bunk room, ski room with boot dryers, hot tub, exterior gas fire pit.

Luxury / trophy custom

6,000–12,000+ SF conditioned, guest wing or separate guest cabin, wine room, indoor sport court or lap pool option, full elevator, home theater, whole-home automation, imported stone and millwork, secondary caretaker/staff quarters. These builds are quoted per project through a signed design agreement.

Jackson Hole subdivisions and communities we work in and near

Coverage areas and subdivisions we work in and near across Teton County WY: Teton Village, Wilson, 3 Creek Ranch, Crescent H Ranch, Shooting Star, Granite Ridge, Indian Springs Ranch, Melody Ranch, Rafter J, John Dodge, Solitude, Skyline Ranch, and unincorporated Teton County parcels. Also comfortable working in the Town of Jackson within permit and zoning restrictions. See our dedicated pages for Teton Village and Alta WY.

What Jackson clients underestimate every time

  • Design review committee timelines. Some subdivision committees meet monthly. If your submission misses the deadline, add 4–6 weeks to your schedule.
  • Wildlife and wetland setbacks. Elk migration corridors, wetland buffers, and riparian setbacks can consume 30–50% of a raw lot’s buildable envelope. Get a professional site analysis before you close on land.
  • WUI fire code compliance. Wildland-Urban Interface overlays add ignition-resistant siding, spark-arrestor chimneys, 30-ft defensible space, and other requirements. See the county’s WUI Information for Contractors page for the specifics.
  • Snow load structure. Trusses, roof framing, and structural connections are meaningfully more expensive at 80–100 psf ground snow load than at typical Idaho valley loads. Budget accordingly.
  • Energy Mitigation Program cost. On any home over 2,500 SF, the EMP fee lands during permit and can total tens of thousands. Design credits (PV, super-insulated envelope, passive design) can offset it — build them into the plan from day one.

Teton County WY permit fees — the actual 2026 math

Teton County WY calculates building permit fees off the current ICC Building Valuation Data, multiplied by tiered coefficients: 0.006 for 1–2,500 SF, 0.009 for 2,501–5,000 SF, and 0.012 for anything over 5,000 SF. Plan review runs 65% of the total building permit fee. Planning review is $125 plus $60 per 1,000 SF over 5,000 SF. Minimum permit fee is $305. All of it comes from the Teton County WY 2026 Fee Schedule.

Then the Energy Mitigation Program stacks on top: $4/SF of conditioned space for 2,501–5,000 SF homes, and $10,000 + $8/SF for anything over 5,000 SF. Credits offset it — $5,000 per kW of installed PV, $8,000 for a super-insulated R-60/R-28 envelope, $8,000 for passive solar design, $8,000 for ductless zoned primary heat, $1,500 for an HRV — and I design them in when they pencil. Non-essential elements are additive and non-refundable: heated exterior hardscape $10/SF, pools $10/SF, solid-fuel decorative devices $5,000 (one-fireplace exception), ponds with pumps $150/hp.

The Land Development Regulations layer sits on top of the building permit and drives its own fee stack that owners routinely underestimate. From the same 2026 schedule: Sketch Plan $3,060, Development Plan $3,060, Conditional Use Permit $3,060, Special Use Permit $3,060, Zoning Map Amendment $2,225, PUD $6,115, LDR Text Amendment $1,985, Variance $1,835, Basic Use Permit $660, Subdivision Plat $1,000 plus technical review. If your parcel is inside the Scenic Preserve, a stewardship fee of $16,150 applies. Grading and erosion control adds $700 at plan level or $400 at statement level. Septic starts at $250 for the first bedroom plus $100 per additional bedroom (county permit fee page). None of these are optional. I map them into the fixed construction contract number, so what you sign is what you pay.

Jackson Hole custom home FAQ

Do you build custom homes in Jackson Hole, Wyoming?

Yes. SwagerBuilds crosses Teton Pass for Jackson, Wilson, Teton Village, and Alta projects and handles the entire Teton County WY permitting process, including LDR, scenic overlay, and HOA design review.

Do I need a different contractor for a cross-state build?

No. I hold Idaho contractor registration (RCE) and Teton County WY contractor registration, and I run the same crew, subs, and JobTread schedule on both sides of the pass.

How much more does it cost to build in Jackson Hole than in Teton Valley, Idaho?

The same specification costs materially more on the Jackson side — stricter design review, the Energy Mitigation Program, a tighter labor pool, and heavier snow-load structure drive the delta. Trophy Village and Wilson-adjacent builds are priced case-by-case above the entry points, always through a signed design agreement.

What is the timeline for a Jackson Hole custom home?

Plan on 20–24 months foundation-to-CO for a full custom, plus the design agreement phase up front. Jackson timelines run longer than Teton Valley because of scenic and overlay review, committee schedules, winter shutdowns, and trade lead times.
