The short version: Teewinot, often searched as Tewinot, is an acreage subdivision north of Driggs along Mt. Moran, Mt. Owen, Middle Teton, and Grand Teton roads, with big Teton views and a short drive to Grand Targhee. Lots run on wells and septic, the roads are private and maintained by the owners association, and every visible exterior structure goes through the association’s architectural committee.

Association details below come from the Teewinot Owners Association’s own website; confirm current rules before you buy or build.

What Teewinot is

• Location. Unincorporated Teton County, Idaho, north of Driggs, with lots along Mt. Moran Road, Mt. Owen Road, Middle Teton Road, and Grand Teton Road.
• Lots. Rural acreage. Past listings show lots around an acre and a half with Teton views, power to the lot line, and a well and septic needed.
• Build-out. The association reports 57 percent of lots built or under construction as of 2026.
• Owners association. The Teewinot Owners Association has a volunteer board, recorded CC&Rs, and bylaws updated in late 2025.

How the owners association affects your build

• Architectural review. Any visible exterior structure, from the house to a garage, shed, deck, or fence, needs architectural control committee review before it goes up.
• Construction fee. $1,500 for new construction to cover road wear. Damage beyond that is billed to the builder.
• Dues. $500 per lot per year for 2025 and 2026.
• Roads. Private roads graded and plowed by a contractor the association hires. Heavy construction traffic in spring breakup is exactly what that $1,500 fee exists for.
• Short-term rentals. Rules and a code of conduct are in place, including a maximum of three people per bedroom.

A finished Teewinot build: the Arbogast home

The Arbogast home sits on Mt. Moran Road in Teewinot. It’s a full-scope SwagerBuilds custom home with a floor-to-ceiling stone fireplace and alder cabinetry built in our Rigby shop. The foundation went in before the fall freeze, the shell was framed and dried in ahead of heavy snow, and interior trades ran through the winter. The owners followed the build from out of state through daily photo logs and approved every change order in writing from their phones. See the Arbogast home →

Rural lot realities to plan for

1. Well and septic. Get a perc test and a realistic well depth before you close. Together they commonly add $25,000 to $45,000 or more.
2. Water rights and irrigation. Surface water rights belong to the subdivision collectively, and the association reports irrigation water is typically used up by mid-August. Landscape plans should assume dry late summers.
3. Power. Confirm where power sits at the lot line and budget the run to the house.
4. Winter access. A contractor plows the private roads, but a winter build still needs a plan for driveway plowing, staging, and deliveries.
5. Snow and wind. Open acreage north of town catches wind and drifting. Roofs need stamped engineering for the site; Teton County, Idaho’s prescriptive roof snow loads start at 85 psf.
6. Growth nearby. The association has been tracking proposed development near 2500 North and a City of Driggs annexation proposal that was tabled. Worth knowing when you think about views and traffic over time.

What a Teewinot build costs

SwagerBuilds custom home construction in Teton Valley starts at $400 per square foot of conditioned space and goes up from there. A 2,500 SF home at that entry point runs about $1M in construction cost and roughly $1.35M all-in once site work, permits, design, contingency, and financing carry are counted. The construction price gets fixed once design and selections are locked in a signed design agreement.

A rural Teewinot lot adds the line items an in-town lot does not: well and septic, a longer driveway and site work, the power run, the $1,500 association construction fee, and annual dues. Site work, septic, well, and driveway on a Teton Valley acreage lot commonly run $80,000 to $250,000 depending on the parcel, and that belongs in the budget before the house does. Compare quotes on the same basis with cost per square foot to build in Teton Valley.

Design agreement 12–16 weeks, including architectural committee review. Teton County, Idaho permitting about 2–3 months. Then 10–16 months of construction.
