If you pull up the zoning on a parcel north of the Frenchtown interchange this fall, what does it actually tell you about what can be built next door?
You'll get a clear answer on paper. On May 28, 2026, the Missoula County commissioners approved citizen-proposed zoning on about 400 acres north of Interstate 90 in Frenchtown. The county's minutes record it as Citizen Zoning District #47, the Frenchtown Interchange Zoning District. That map now sits on top of two open questions. One could put a large commercial use on the ground while the zoning stays in place. The other could replace the zoning altogether within about two years. A buyer weighing acreage out here is reading a document whose meaning is still being decided.
Three Densities on One Map
The district has three parts, and the split matters for anyone comparing parcels inside it. According to Montana Free Press, the zoning breaks down like this:
| Portion of the district | What the zoning allows |
|---|---|
| Most of the roughly 400 acres | One house per 5 acres |
| About 14 acres around existing development in the middle of the area | One house per acre |
| 7 acres along Belker Lane and Frenchtown Frontage Road | Light industrial use |
For a buyer, the five-acre rule is the headline. It holds most of the land to a rural density near an interstate exit, where a growth policy would normally steer commercial building. Some landowners objected during the hearings because the zoning wouldn't let them develop commercial businesses or professional offices on their own property. The same rule that protects one owner's view and quiet takes development options away from the owner next door. Those two parcels can sit side by side on the same map.
A District Drawn Around One Site
The density table tells you what the zoning says. Why it was drawn tells you how settled it is. Montana Free Press reported that the zoning was proposed in part to block a planned Town Pump travel plaza, on a site just east of Frenchtown High School that the new rules wouldn't allow. The petition came from Keeping Frenchtown, a community nonprofit. After the vote, the group said in a statement that "our community's water supply, the safety of our children, and the quality of life on our roads are at the heart of this effort."
The project behind all this is substantial. At the meeting, Town Pump's construction and development manager described a 25,700-square-foot convenience store with showers for truckers and travelers, a casino with a pending beer and wine license, and 57 overnight parking spaces for trucks and RVs. That's according to Montana Free Press. The Missoulian described the building permit Town Pump submitted as covering a 30,000-square-foot store with roughly 50 overnight truck spots. It also reported that the company owns roughly 35 acres in the Frenchtown area.
The debate on the dais shows how thin the planning ground under this district is. Town Pump's chief legal counsel, Dan Manson, argued that the growth policy calls for commercial development near the interstate. Montana Free Press quoted him saying the zoning was "tailored to stop a project." County planner Jennie Dixon acknowledged the age of the area's growth plan and said there are no newer documents to guide decisions. The Missoula County Planning and Zoning Commission voted 4-2 to recommend approval. Clerk/Recorder Tyler Gernant, one of the two votes against, called complying with the growth plan from 1975 "virtually impossible." The commissioners then approved the zoning unanimously, and both of the commissioners Montana Free Press quoted said they had reservations.
A district adopted that way, by officials who said they had doubts, is the first sign that this map may not stay as it is.
The Vesting Question Has No Textbook Answer
The new zoning doesn't allow gas stations. Town Pump has argued that it already holds a vested right to its project, meaning rules adopted late in the process can't stop it. That's according to the Missoulian.
What surprises most people is how loosely the law defines that idea. At an April 30, 2026 commission meeting, Deputy County Attorney John Hart told commissioners that vested rights aren't defined in Montana court decisions, in the zoning statutes the legislature has enacted, or in the county's own zoning regulations. The best working definition he could offer came from a legal hornbook. He also said the county's regulations do recognize the concept, and that the planning office has an application form for it.
Based on the Missoulian's account and the county's minutes, the process runs in this order:
- Town Pump filed a completed application asking the county to find that it has a vested right to its development proposal.
- Missoula County zoning officer Karen Hughes makes an administrative decision on that request.
- Her decision can be appealed to the Missoula County Consolidated Land Use Board, and the Missoulian noted that several other options are possible before a final ruling.
- While that plays out, a tolling agreement between the county and Town Pump delays a possible lawsuit over the zoning itself. Without the agreement, Hart said, the company would have had about 60 days after approval to sue.
Hart told commissioners that the eventual decision "will probably not make everybody happy." In a statement to KPAX that the Missoulian quoted, Town Pump said it was "evaluating our rights and options" and hoped to move forward. In the Missoulian's most recent account of the process, the decision still sat with the zoning officer, and an appeal could follow it.
Commissioner Dave Strohmaier put the practical stakes plainly before the vote, as reported by Montana Free Press:
"I will say, be careful what you wish for. I am not going to be the one deciding this, but there will be a process to determine vesting. And I will not at all be surprised if you, in the community, end up with zoning and a Town Pump simultaneously."
In that scenario, a parcel limited to one house per five acres could end up near a large truck stop that the same zoning would ban if it were proposed today.
The Second Clock Runs Into 2027
Even if the vesting question were settled tomorrow, the citizen zoning may have a limited life. Missoula County has started a Comprehensive Plan Update for everything outside Missoula city limits. The county describes it as a two-year process that will likely continue into 2027. The county first adopted a comprehensive plan in 1975. The one in use now dates to 2016, with a substantial amendment in 2019.
Dixon told commissioners that any zoning adopted after the countywide process would supersede the citizen zoning. Strohmaier called the citizen petition route a "pretty poor way" to go about land use planning. He said he supported it because it would likely line up somewhat with the zoning expected to come out of the countywide plan. Commissioner Josh Slotnick said he wouldn't have approved the petition without that planning process on the horizon.
The county is careful about what the plan itself does. It says the comprehensive plan isn't a regulatory tool, and that under Montana law, subdivisions and development can't be denied based on the plan alone. It does provide the path and legal basis for adopting or updating future zoning and subdivision regulations. The plan will also identify locations the county considers appropriate for development and locations it doesn't. For the land north of the interchange, that means the current five-acre rule could be confirmed, loosened or tightened in a process that hasn't finished yet.
Two clocks are running, then. The vesting decision and any appeal will determine whether one large project goes ahead under the old rules. The comprehensive plan will lay the groundwork for whatever zoning the county adopts or updates after it, and that zoning would govern everything else.
Reading a Parcel Near the Interchange This Fall
None of this makes the Frenchtown interchange area a poor place to buy. It means the price of a parcel here partly reflects an outcome nobody knows yet. A buyer who understands that can ask better questions before writing an offer:
- Which of the three density areas on the map does the parcel fall in, and how close is it to the Town Pump site east of Frenchtown High School?
- What does Missoula County's planning office currently show for the vested-rights application, and has a decision or appeal been posted?
- If a lot is priced on its development potential, what does that potential depend on: the citizen zoning as written, or zoning that may follow the comprehensive plan?
- When the county schedules public engagement for the Comprehensive Plan Update, which sessions will cover Frenchtown and the west valley?
On the seller side, the same uncertainty belongs in the conversation from the start. A buyer who has read the Montana Free Press coverage will bring it to the table either way.
This post is general information about public zoning and planning processes, not legal advice. Anyone whose purchase or sale depends on vested rights or future zoning should confirm the details with Missoula County planning staff and a Montana real estate attorney.
