Teton County, Idaho Building Permits: Timeline, Requirements, and What to Expect
Permitting is where most Teton Valley building projects lose time. Not because the requirements are unreasonable, but because they are sequential. Several approvals have to happen before the building permit application can even be approved, and homeowners who do not know that find out after they have already submitted.
Here is the actual process, including how long it takes.
Two very different answers depending on where your parcel sits:
Jurisdiction Typical permit timeline
Unincorporated Teton County 2 to 4 months after a complete application is submitted
Inside Driggs, Victor, or Tetonia city limits 3 to 5 weeks
A note on these numbers: these timelines are our estimates based on what we have seen on our own projects, not published figures from the county or the cities. Actual review times vary throughout the year depending on the workload at each building department, so treat them as a planning range rather than a guarantee.
Read the county row carefully: after a complete application is submitted. That clock does not start when you decide to build. It starts once your engineered plans, your septic permit, your grading permit, and every other prerequisite are already in hand.
Which is why the real timeline is longer than the permit timeline, and why the sequence below matters more than the calendar.

How long does it actually take?
On every project, we begin with the Grading and Erosion Control (GEC) permit and the septic permit. Both are prerequisites for the building permit application, and both take time that runs in parallel with design if you start them early enough.
The septic permit in particular requires an onsite evaluation with dug test holes, which means it depends on ground conditions and on the health district's schedule, neither of which you control. Starting it late is the most common way a project loses a month for no reason.

Start these two first
This determines everything else, and it is not always obvious from an address.
Check the parcel on the Teton County GIS zoning map, then confirm with staff. Building to the wrong jurisdiction's standards is an expensive correction.
- Unincorporated Teton County: Teton County Building Department, 150 Courthouse Drive #107, Driggs
- Inside Driggs city limits: City of Driggs Planning and Building
- Inside Victor city limits: City of Victor
- Inside Tetonia city limits: City of Tetonia
- Area of City Impact: this one catches people. A parcel just outside city limits can still fall within a city's Area of Impact, which means it is subject to that city's zoning ordinance but administered by Teton County. Driggs and the County updated the Area of City Impact ordinance effective December 2024.

First: which jurisdiction are you in?
For an unincorporated county parcel, here is what goes in with the application:
- The application itself, completed in full, with any non-applicable sections marked as such. Incomplete applications get returned.
- Design Standards Checklist, signed, from the county Forms page.
- Plans stamped by an Idaho-licensed structural engineer. Not optional. Building height must be shown from grade to the highest ridge point.
- Site plan showing all existing and proposed structures, the driveway, and well and septic locations, with measurements to each property line. Critically: the same site plan must be used for the Grading and Erosion Control permit, the building permit, and the septic permit. Change it in one place and you resubmit everywhere.
- Proof of ownership, warranty deed or quit claim deed. If an LLC owns the parcel, documentation of your signing authority.
- Letter of authorization if someone other than the owner is signing.
- Septic or sewer permit. If you are not on Driggs or Victor water and sewer, you need a septic permit from Eastern Idaho Public Health before building permit approval. If you are in a subdivision served by city sewer, you need a connection agreement with the city instead. For remodels adding a bedroom or bathroom, you need Permission to Connect to an Existing System from EIPH.
- Energy analysis. Either a REScheck report from energycodes.gov, or the prescriptive method form included in the permit application.
- Grading and Erosion Control (GEC) permit. Approval from the County Public Works Director is required before any land-disturbing activity unless specifically exempted. This surprises people who assume they can start clearing while the permit is under review.
- Wildlife Habitat Analysis. If your parcel falls within any Natural Resource Overlay on the county GIS map, you may need a full or abbreviated WHA. If your lot was platted for natural resources or has established building envelopes, include that in your narrative.
- Scenic Corridor, floodplain, wetlands, or Road and Bridge approval. If any apply to your property, those approvals come first and get submitted with the application.
- Owner acknowledgments, a set of jobsite requirements you initial, covering permit posting, sanitation facilities, debris removal, and inspections.
The Teton County residential submittal checklist
Worth reading before you initial:
- Name, address, and permit must be posted clearly on the site
- A port-a-potty or sanitation access is required on all job sites
- A dumpster is required, or construction debris removed weekly. No burning without a permit from the Teton County Fire District.
- Address posting per Teton County Title 13
- Occupying the structure before final inspections can subject you to fines under Title 6
Jobsite requirements you are agreeing to
This trips up owner-builders in particular. Before you can call for a final county inspection, you need:
Three separate agencies, in order. Scheduling them back to back without gaps is a meaningful part of what a general contractor does for you.
- Final inspections from the State Division of Building Safety electrical and plumbing inspectors
- Final inspection and approval of the septic system from Eastern Idaho Public Health, required before Certificate of Occupancy
- Then the county final inspection

The inspection sequence at the end
Teton Valley jurisdictions adopt the International Codes as adopted by the Idaho Division of Building Safety. Snow load is the design factor that most distinguishes building here. Structural engineering in Teton Valley starts at a minimum ground snow load of 85 psf on the valley floor, and that requirement increases as elevation increases. It drives roof framing, truss design, and structural engineering throughout the house, so a home in the foothills or up a canyon will be engineered to a higher number than one on the valley floor.
Confirm the current adopted code edition and the required snow load for your specific site with your jurisdiction at the start of design. Engineering to the wrong number means a redesign.

Building codes and snow load
Driggs adds the Land Development Code on top of building code: zoning standards for setbacks and height, building type and architectural design requirements, special districts including floodplain, Design Review, airport, and Tributary PUD overlays, use provisions, and site development standards covering access, parking, landscaping, screening, and outdoor lighting. Driggs also has a dark-sky outdoor lighting ordinance that applies to residential exterior lighting.
If your project falls in the Design Review Overlay, that is a separate application and review process before building permit. Plan for it in your schedule.
Victor and Tetonia have their own ordinances and application processes. Confirm requirements directly with each city.

City-specific layers
In order of how often we see them:
- Unfinished plans. An application submitted against drawings that are not actually done is the single biggest source of lost time. The county reviews what you give them, and gaps come back as corrections.
- Change orders during review. Revise the design after submittal and you restart parts of the review, sometimes across multiple offices.
- Geotechnical analysis. If the county engineer requests a geotech report on your site, that is an added study with its own turnaround. It is not required on every project, but when it comes up late it is expensive in schedule.
- Site plan changes after submittal. One change means resubmitting to every office using that plan.
- Starting septic too late. It is a prerequisite, and it requires a site evaluation with dug test holes.
- Land disturbance before the GEC permit. Avoidable and costly.
- Discovering an overlay late, whether Natural Resource, Scenic Corridor, floodplain, or Design Review, after design is complete.
The most common causes of delay
How long does a building permit take in Teton County, Idaho?
In our experience, roughly 2 to 4 months for unincorporated county parcels once a complete application is submitted. Inside Driggs, Victor, or Tetonia city limits it is closer to 3 to 5 weeks. These are our estimates, and review times vary throughout the year with building department workloads.
Who issues building permits in Teton County, Idaho?
The Teton County Building Department for unincorporated parcels, or the City of Driggs, Victor, or Tetonia for parcels inside city limits. Parcels in an Area of City Impact follow city zoning but are administered by the county.
Do I need a septic permit before my building permit?
Yes, if you are not connected to Driggs or Victor city sewer. The septic permit from Eastern Idaho Public Health must be obtained before building permit approval.
Can I start site work before my permit is issued?
Not without a Grading and Erosion Control permit approved by the County Public Works Director. Land-disturbing activity before that approval can result in enforcement.
What is the ground snow load in Teton Valley?
A minimum of 85 psf on the valley floor, and the requirement increases as elevation increases. Confirm the figure for your specific site with the building department before finalizing design.
What is the fastest way to get through permitting?
Finish your plans completely before submitting, and start the septic and grading permits early, in parallel with design rather than after it.
