Building permits, zoning and land rules in Teton County, Wyoming

#11 of 23 in Wyoming

Teton County, Wyoming requires a building permit for new structures and many additions or alterations in unincorporated areas, with narrow exceptions for qualifying agricultural and small non-habitable accessory buildings1. County zoning applies to unincorporated parcels, while the Town of Jackson is a different jurisdiction with different regulations2,3. Septic permits come from the county, and the county's land development regulations prohibit using a camping trailer or RV as residential living quarters4,5.

Do you need a building permit in Teton County, Wyoming?

Yes, in unincorporated Teton County.

Yes, in unincorporated Teton County. The county requires a building permit for new structures and listed work such as additions, porches, certain retaining walls, roof or window replacements, exterior doors, interior remodels, and elevated decks1. Qualifying agriculture-related buildings are excepted only when they house farm implements, feed, or livestock, are under 600 square feet, and have no more than two sides; a planning review may still be necessary1. Small non-habitable accessory structures also have a limited exception under the county's stated conditions1.

Applications submitted on or after February 1, 2025 must use the 2024 IRC and IBC editions8. The county's building-code adoption lists the 2024 International Building Code9. Plan review adds a fee equal to 65% of the building permit fee10. Permit holders must request inspections when work is ready, and inspections must occur at least every 180 days to keep a permit active8.

Who issues Teton County building permits, and how do you reach them?

The Teton County Planning & Building Department handles county building permits through its Building Division at 200 S Willow Street in Jackson.

The Teton County Planning & Building Department handles county building permits through its Building Division at 200 S Willow Street in Jackson8. Call 307-733-7030 for permit-process questions, submit the application through the county online portal, and request inspections online or by telephone8. New residential, commercial, and small miscellaneous projects require scheduled submission weeks, while trade permits do not3.

Planning applications are digital through the SmartGov portal3. For allowed uses, setbacks, height limits, and planning approvals, contact Teton County Planning at 307-733-3959 or planneroftheday@tetoncountywy.gov11. County and municipal jurisdictions have different regulations, so use the parcel's jurisdiction rather than its mailing address to choose the correct office3.

Does Teton County have zoning?

Yes, in unincorporated Teton County.

Yes, in unincorporated Teton County. The Teton County Land Development Regulations establish urban, suburban, rural, conservation, special-purpose, and overlay zoning classifications for unincorporated Teton County2. County and municipal jurisdictions have different regulations3.

A parcel's district, proposed use, and recorded plat matter because building-height restrictions depend on zoning and sometimes use, while a subdivision plat may add restrictions3. Natural-resource setbacks include 150 feet from rivers, 100 feet from perennial or intermittent streams and natural lakes or ponds, 30 feet from ephemeral streams, and 50 feet from wetlands3. We could not confirm countywide numeric rules for minimum dwelling size, minimum lot size, or lot coverage; ask the Planner of the Day for a parcel determination before design begins11.

How do septic permits work in Teton County?

Teton County administers small wastewater facilities under authority delegated by the Wyoming Department of Environmental Quality, and the county rules may not be less stringent than corresponding state regulations.

Teton County administers small wastewater facilities under authority delegated by the Wyoming Department of Environmental Quality, and the county rules may not be less stringent than corresponding state regulations4. A county permit is required before constructing, installing, or modifying a small wastewater facility, apart from the stated initial emergency-response exception4. Contact Engineering at 307-733-3317 or engineering@tetoncountywy.gov before fixing the house location or system design12.

Only 3.4% of mapped county soils are rated without severe limitations for a conventional septic drain field, so test wastewater feasibility early rather than assuming acreage guarantees a workable conventional system13. Privies or outhouses may not be built within the 100-year floodplain, and the design engineer must certify that an installed small wastewater system conforms to the approved design before or with the Sanitarian's final inspection14. We could not confirm every off-grid sanitation alternative that qualifies; ask Engineering about the proposed system and parcel12.

Can you live in an RV or tiny home on land in Teton County?

No for an RV, with one exception.

No for an RV, with one exception. The Teton County Land Development Regulations prohibit using a camping trailer or RV as residential living quarters, except for temporary use of a trailer in conjunction with an active building permit for a residential structure5. A camping trailer in use must be parked in an authorized campground, though the county does not stop you from storing it on your property when not in use, as long as outside-storage standards are met5.

We could not confirm a countywide rule on tiny-home occupancy in unincorporated Teton County; ask the Planner of the Day how the parcel's zoning district, proposed use, wastewater plan, and recorded plat affect it11. A small dwelling is still within the county's building-permit framework, and the confirmed accessory-structure exception covers only non-habitable structures1. Constructing, installing, or modifying a small wastewater facility also requires a septic permit from the county4. Short-term rentals are limited in unincorporated Teton County: rentals under 31 days are prohibited except in listed locations3.

Building a home in Teton County: what are the steps?

Confirm whether the parcel is in unincorporated Teton County or a municipality, because the jurisdictions use different regulations.

  1. Confirm whether the parcel is in unincorporated Teton County or a municipality, because the jurisdictions use different regulations3.
  2. Ask Planning to identify the zoning district, allowed use, setbacks, district-specific height limits, plat restrictions, and required applications2,3.
  3. Resolve the wastewater design with Teton County Engineering and obtain the required permit before installation or modification4.
  4. Obtain an approved Wyoming groundwater permit before drilling a private well; domestic and stock applications carry a $50 filing fee6.
  5. File digital planning applications and the building application through SmartGov, scheduling a submission week when the project type requires one3,8.
  6. If access connects to a county road, obtain the no-charge Road Access Permit15.
  7. Request inspections online or by telephone when work is ready and keep them within 180 days of one another while the permit remains active8.

What should you check before buying land in Teton County?

Start with jurisdiction, zoning, the recorded plat, legal access, water, wastewater feasibility, and mapped floodplain.

Start with jurisdiction, zoning, the recorded plat, legal access, water, wastewater feasibility, and mapped floodplain. County zoning regulates unincorporated land, municipal regulations differ, and subdivision or platting is regulated through the county Land Development Regulations2,3. For parcels of 35 acres or more covered by Wyoming's large-parcel rule, binding and recordable access and utility easements must generally be at least 40 feet wide to a public road unless properly waived16.

Ask Floodplain Management about permit requirements if mapping places a building site in a floodplain17. A driveway from a county road requires a county Road Access Permit15. Septic deserves special attention because only 3.4% of mapped soils avoid a severe conventional-drain-field limitation13. The effective property-tax rate is about 0.4%, and the median annual property-tax bill is $5,46213.

Watch-outs

  • Do not plan to live in an RV while you build unless an active residential building permit is in place; the county prohibits RVs as residential living quarters otherwise5.
  • Do not apply municipal rules to an unincorporated Teton County parcel; county and municipal jurisdictions have different regulations3.
  • Natural-resource buffers can move a building envelope substantially: confirmed county setbacks reach 150 feet from rivers and 50 feet from wetlands3.
  • A private well needs an approved Wyoming groundwater permit before drilling begins6.
  • The agricultural building exception is narrow, and qualifying buildings may still need planning review1.
  • Wyoming does not require a statewide general-contractor license for an owner working on a primary residence, but county approvals still apply and we could not confirm a separate county owner-builder exemption7,8.
