The honest read
Building in Star Valley.
Alpine to Afton: who reviews your house, what the land asks of it, and what I'd check before you buy.
Star Valley is an easier place to build than Jackson. If you expect a simpler process, you're right.
Building can cost less here too. Build for the long run anyway: the savings belong in the price, not in the details that keep out water, wind and snow.
There are builders here doing good work. Find the one who has built at the level and scale of your house, and go see what they've finished.
I live in Alpine and have worked with the town's permit office myself. For the other towns and the county, I've gone by each office's current forms, checked 30 October 2026. I check them again every spring.
The first question on any parcel
Town or county: who reviews your house
Alpine, Star Valley Ranch, Thayne and Afton are incorporated and run their own reviews. Etna, Freedom, Bedford, Auburn, Grover, Smoot and the land between are unincorporated Lincoln County.
| Where the lot is | Who reviews the house | What is checked | Submittal to permit |
|---|---|---|---|
| Alpine | The Planning & Zoning Commission reviews the site plan; the Building Official reviews the plans. | 2021 codes. The town inspects. | About four weeks. |
| Star Valley Ranch | The association's architectural committee first, then the town. | 2021 codes, an engineer's stamp on every house, twelve town inspections. | Four weeks to two months, by plat. |
| Thayne | Town Council and Planning & Zoning, at the monthly meeting. | 2021 codes. | About four weeks, if the packet is in two weeks before the meeting. |
| Afton | The Building Official and Zoning Administrator. | The latest adopted IRC and IBC. A surveyor certifies where the foundation sits. | Up to 30 days. |
| The county | Lincoln County Office of Planning and Development, in Afton. | Zoning, setbacks, access and septic. No plan review and no inspections. | Two to three weeks. |
Inside a town, someone checks the house. In the county, nobody does unless you hire them, and the county's own packet says so.
Residential permits
Office by office
For a single-family house. Commercial work follows other rules in every one of these offices.
Alpine
- Apply through the town's online permit system by the 15th of the month. The commission reviews the site plan; the Building Official reviews the plans and inspects.
- A single-family house in R1 skips Design Review. Only R2 and up, multi-unit and commercial work go to the Design Review Committee.
- Three sets of the site plan, architectural and engineered drawings, plus one digital set. The site plan shows access, finish grade, every utility, setbacks, parking, drainage and calculated snow storage.
- The fee is the ICC building valuation × 0.010, covering site plan review, plan review and town inspections. Water and sewer connection fees are paid in full before the permit issues.
- Septic permits go to Wyoming DEQ in Lander. Electrical goes through the state.
- An application is good for 90 days. Once it is accepted, the town has 30 days to put it on the commission's agenda.
Star Valley Ranch
- Two approvals, association first: the Star Valley Ranch Association's Certificate of Conformity, then the town's building permit. Neither replaces the other, and the town does not enforce the covenants. Start the association packet once the plot plan, plans and colors are settled, and have the town submittal ready behind it.
- The association's packet: an improvement request, the owner's signed certification, a materials form with color samples for siding, trim, doors and roofing, a dimensioned plot plan, one set of plans and a front-yard landscaping plan. There is no fee, and the committee's clock starts when the packet is complete.
- Its rules: no manufactured homes, new materials only, colors approved before you paint. One house, a garage and one outbuilding; anything over 200 sf needs its own certificate, and every shed sits inside the setbacks.
- The town permit is $500 plus $1 per sf of the footprint of the house and attached garage, 7–10 business days after a complete application. Every new house needs a full structural set stamped by a Wyoming engineer.
- Twelve town inspections, and a Wyoming surveyor's Certificate of Placement before the foundation is poured. Corner pins exposed and flagged on a 3-ft post; wooden stakes alone are refused.
- A water tap is $7,500 inside town limits. The septic permit is $350.
Minimum house size and setbacks come from the covenants of the plat the lot is in. Every plat allows one house and a garage for up to three cars. If the committee has not acted within the listed days of a complete submittal, approval is deemed given.
| Plats | Minimum floor area | Front | Rear | Side | Committee has |
|---|---|---|---|---|---|
| 1 & 2, 3, 5 & 6, 7 & 8, 9 & 10, 20 Prater Canyon Estates | 750 sf | 30 ft | 10 ft | 10 ft | 15 days |
| 12, 13 & 14, 15 & 16 | 750 sf | 30 ft | 30 ft | 10 ft | 45 days |
| 4, 11 & 22, 17 & 18, 21 | 900 sf | 30 ft | 30 ft | 12 ft, 30 ft on the golf course | 45 days |
Thayne
- Reviewed at the monthly Town Council and Planning & Zoning meeting. A complete packet has to arrive two weeks before, or it waits a month.
- The 2021 codes. A site plan on 11×17 with setbacks, the surveyor's lot dimensions, every building with its exact perimeter (propane tanks and yard hydrants included), utilities, easements, landscaping, snow storage and parking. Elevations, floor plan, wall sections, the deed and site photos.
- Where there is an association, its written approval goes in the packet, so it comes first here too.
- Every contractor and subcontractor needs a Thayne business license.
- A water impact fee of $6,800 for a 1-inch tap and a sewer impact fee of $7,300, plus $500 to connect each, paid before the tap.
Afton
- Any new house over 600 sf needs a permit, with a $100 application fee. Incomplete applications are refused; a complete one takes up to 30 days.
- A roof snow load of 80 lb/sf, non-reducible. Seismic D-2, 80 mph wind.
- Every lot corner found and staked. Before the foundation is placed, a licensed surveyor certifies the forms match the approved site plan, or work stops for the town to review.
- Drawings stamped by a Wyoming engineer, or the owner signs to accept the liability.
- R1 lots are 13,500 sf minimum, with 35% lot coverage and a 35 ft height limit.
Unincorporated Lincoln County
- A Residential Use Permit from the Office of Planning and Development in Afton. It covers zoning, setbacks, access and septic. It does not cover the building.
- No plan review and no inspections. The county recommends building to IRC 2006 or newer and hiring a certified inspector for six inspections: plan review, footing, foundation, rough-in, insulation and final.
- Checked for completeness within 7 days, decided within 14. Work has to start within two years.
- Setbacks of 10 ft at the sides and rear, 15 ft in front or 20 ft with parking in front. 150 ft from the Salt River's high-water line in the floodplain, 50 ft from other streams.
- A perc test and a county septic permit. The tank sits 50 ft and the drainfield 100 ft from any well, the neighbor's included.
- A driveway no steeper than 6% for its first 150 ft.
- The county does not check covenants, so a county permit can conflict with an association's rules.
What I look at
The land, the water and the build
- Covenants and associations
- Alpine Meadows and Star Valley Ranch are the associations to know. Reviews here are usually short, and you hear quickly what they want changed. Very few associations are professionally managed, so sometimes you have to ask the neighbors and your agent who the contact is, then work with that person directly so nothing surprises you later.
- Water and septic
- Groundwater depth varies, but unless you're in a river bottom, perc tests are generally favorable. If you can tap a town system, do it: owning and maintaining a well and septic system costs more over time. Irrigation rights depend on the property and the rights that come with it. Understand them during due diligence, and bring in a real estate attorney if they're unclear.
- Snow, slope, flood and fire
Lincoln County has no wildland-urban interface standards yet, but houses are getting harder to insure regardless, and insurers are wary of hillside building, wildfire and runoff. I take a practical approach to wildfire and to how the climate shapes the house. The view might be to the north, but no one wants to sit on a north-facing deck in the cold of the evening.
The county recommends roof snow loads of 50–100 lb/sf by zone and foundations 36–42 inches deep. Afton requires 80. A lot in a floodplain or wetland needs its own county permit.
- Who checks the work
- Keep the architect on for regular site observation, and hire an independent inspector for higher-end and more complicated work. Even on small houses, things get missed. A second set of eyes is what keeps the house sound for the long run, and in the county it may be the only set.
- How long it takes
- Most owners can expect 12–18 months from buying the land to moving in, depending on the size and scale of the house. Larger, more complex houses take more design, engineering and construction: 18–36 months from purchase to completion.
Before you buy in Star Valley
Eight questions to ask here that you wouldn't in Jackson
- Who reviews this lot: a town, the county, or a town and an association? In Star Valley Ranch, which plat is it in?
- Can it tap a town water and sewer system, or will it need a well and septic? Is there room to keep them the required distance apart?
- Has anyone run a perc test here, and is the lot in a river bottom?
- Is there a current survey? On a sloped lot, is a geotechnical report worth having before closing?
- What irrigation rights come with the property, and are they written down?
- Who is the association's contact, and what do its covenants require: minimum size, setbacks, colors, outbuildings?
- Can you insure a house here? Ask an insurer about wildfire and slope before you buy.
- Which builders here have built at the level you want, and when can they start?
Twenty years of designing houses for how people live in the mountains.
That experience makes the process shorter and the decisions clearer.
