Do you need a permit to stain or re-chink a log home?

Restaining a log home feels like painting, and in much of the valley the codes treat it that way. None of the published permit lists names chinking. Replacing a rotted log is structural work. Which rules apply depends on who has authority over the parcel, and in Jackson Hole and Teton Valley that can be any of five offices in two states.

Teton County, Wyoming and the City of Driggs both list exterior painting and similar finish work as not needing a building permit. Log replacement or structural rot repair may need a permit anywhere.

Step 1: Find out which office has the parcel

"Jackson Hole" is the name of the valley, not a jurisdiction. On the Wyoming side, a property is either inside Town of Jackson limits or under Teton County, Wyoming. On the Idaho side, it's inside Driggs or Victor city limits or under Teton County, Idaho. The two Teton Counties are separate counties in separate states, with separate codes.

Teton County, Wyoming

The county's 2024 Building Codes Resolution took effect February 1, 2025. It applies to "all of the unincorporated lands within Teton County," and it adopts the 2024 International Building Code, International Residential Code, and related codes.

Table 1 in the resolution, "When Permits Are Required," gives a direct answer. It lists "Painting, Papering or Similar Finish Work-Exterior or Interior" under no permit required. It also lists repair or replacement of exterior siding as no permit required, while replacing a roof or adding an exterior window does need one.

The table comes with a caveat in its own text: "This Table is a Permit Requirement Guideline ONLY, and does not take precedence over the Teton County Land Use Regulations or the International Codes as adopted by Teton County." The county's web page adds that a Miscellaneous Permit may be needed for minimal projects, and that a Planning Review may be needed for setbacks even without a building permit. For code and zoning questions, the county lists 307-733-3959.

Staining a log wall fits the finish-work line. Cutting out and replacing a log, or repairing rot that reaches into a structural member, doesn't appear in the table as finish work. Call the county before that work starts.

Town of Jackson

The Town's residential permit page lists permits for new homes, larger decks, accessory structures, retaining walls, and residential alterations, repairs, and additions. Inside Town limits, call the Building Department at 307-733-0440 ext. 1352 before work that goes beyond cleaning and refinishing.

The Town has adopted the 2024 International Residential Code and the 2021 International Energy Conservation Code. Its design criteria rate weathering "Severe," a rating that sets requirements for concrete and masonry.

City of Driggs

The Driggs planning FAQ is direct. It exempts "Painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work" from a building permit. It also says building permits are required for "any construction, addition, alteration, repair, relocation, demolition." So restaining falls under exempt finish work, and replacing a log is a repair that likely needs a permit. Plumbing and electrical permits in Driggs come from the State of Idaho, not the city.

City of Victor and Teton County, Idaho

Neither the City of Victor's building page nor the Teton County, Idaho building regulations page addresses painting or finish work. Don't assume an exemption. Call Victor Planning & Building at 208-274-7082, or the county building department at 208-776-8171. Victor's page notes that plumbing and electrical inspections are handled through the State of Idaho.

Wildland-urban interface rules (Wyoming side)

Since January 1, 2025, every private parcel in the Town of Jackson and Teton County, Wyoming has been inside the mapped wildland-urban interface and subject to review under the 2024 International Wildland-Urban Interface Code. The county's contractor page says re-roofs and interior-only projects don't need a WUI permit. Jackson Hole Fire/EMS issues WUI permits.

Neither the county's WUI page nor the Town's permit page says whether restaining or re-chinking an existing log wall triggers WUI review. Replacing logs or siding can raise WUI questions, so ask Jackson Hole Fire/EMS before that kind of work.

Historic properties in Jackson

The Jackson Historic Register is voluntary. Listing "always requires the consent of the landowner," and the Town can't designate a property without permission. A listed property needs a Certificate of Appropriateness for "any significant change, addition, repositioning, or relocation," and the Town's Historic Preservation Design Guidelines apply. The Town's page doesn't say refinishing needs a certificate. If your home is listed and you plan to change materials or color, ask the Town first.

Who has to hold a license

Permit rules and contractor rules connect. In unincorporated Teton County, Wyoming, a contractor doing work that requires a permit must hold a Town of Jackson contractor license. The hiring guide covers that rule, Idaho's registration law, and the exemptions.

A checklist before work starts

1. Confirm which office has your parcel.
2. Describe the scope to that office in plain words: "restain the exterior," "replace chinking," "replace two rotted logs."
3. Ask whether a building permit, a Miscellaneous Permit, or a planning review applies.
4. On the Wyoming side, ask Jackson Hole Fire/EMS about WUI if any logs or siding are being replaced.
5. Check HOA rules and any historic listing.
6. Write down who you spoke to and the date.

Rules change, and the offices above have the final word. To plan the timing once permits are clear, see the staining season guide, or send a request describing the house.
