Sean Lewis and his wife own 59 acres on Teepee Ridge Road in Bridger Canyon. In 2021, the Bridger Canyon Property Owners' Association filed a complaint against them with Gallatin County. The issue was their caretaker residence, a permitted structure on their property that neighbors believed was being used as a short-term rental. By late 2023, the county had revoked their conditional use permit entirely. The couple spent three years and tens of thousands of dollars in legal fees before the county issued them a new permit with two variances, just to bring the building back into compliance.
Nothing about their property changed during those three years. What changed was how the county chose to read a zoning document written decades earlier, and what that reading meant for a use nobody had explicitly written down.
That's the part buyers moving into Bridger Canyon often miss. The same 1971 zoning district that keeps this canyon rare, quiet, and expensive is the document that can quietly forbid you from renting the place out.
The Rule Most Buyers Don't Expect
Most people assume zoning works like a list of things you can't do. Bridger Canyon works the opposite way. Its zoning regulation operates as a list of things you're allowed to do, and if a use isn't on that list, the county's position is that it's prohibited everywhere in the district.
Gallatin County states this directly on its own short-term rental guidance page: "If short-term rentals are not mentioned in the specific zoning district regulation, they are not permitted anywhere in that zoning district." The same page notes the contrast that makes Bridger Canyon unusual: in unzoned parts of the county, short-term rentals are allowable from the planning department's perspective because there are no restrictions on use at all.
Bridger Canyon is zoned. Almost the entire district falls under what's called the AE subdistrict, and per the property owners' association's own zoning FAQ, almost everyone in the canyon sits in that AE subdistrict, governed by Chapter 6 of the zoning regulation. Short-term rentals, as a defined use, don't appear in that chapter's list of permitted or conditional uses. Under the county's stated interpretation, that silence is the answer.
This isn't a new reading invented to catch the Lewis family off guard. County officials pointed to language in the regulation that traces back decades: "Going back to at least 1989, there's language in the zoning regulations for Bridger Canyon, that if the use isn't listed, then it's prohibited." The rule was always there. It just hadn't been tested against a case that made it into the local paper until recently.
One Enforcement Action Became Two
The Lewis case wasn't isolated. In a November hearing the same season, the Bridger Canyon Planning and Zoning Commission revoked another Caretaker's Residence conditional use permit on the grounds that its use as a short-term rental contradicted the conditions of approval and did not constitute bona fide caretaking, marking the second similar revocation in the canyon.
That pattern is what pulled Wendy Dickson into the fight. She'd operated a short-term rental in the district since the early 2000s and held a valid tourist home permit from Montana's health department. It wasn't until the Lewis revocation that she understood, by the county's own account, that her business was already out of compliance with the zoning regulation, regardless of her health department paperwork. She called a community meeting at the Bridger Canyon Fire Department's community room to organize a response, which is how a caretaker-residence dispute over one 59-acre parcel became a canyon-wide fight over what "residential" is allowed to mean.
The Fight Moved to Helena, and the Outcome Is Still Unsettled
By the 2025 Montana legislative session, that fight had a bill number, or several. State Senator Greg Hertz introduced Senate Bill 336, which would have classified short-term rentals as a residential, noncommercial use statewide unless a local government explicitly prohibited them, effectively flipping Bridger Canyon's silence rule on its head. Hertz told the committee that if local governments are going to regulate short-term rentals, they first need to be defined, arguing they should be classified as residential because the vast majority sit in residential-zoned areas. The bill cleared its Senate committee, but according to the legislature's own bill tracker, it ultimately died in a House standing committee on May 23, 2025.
A companion effort, House Bill 614, took a different angle entirely. Rather than redefining short-term rentals, it would let counties dissolve individual zoning districts like Bridger Canyon's, provided the district gets folded into a countywide framework. The bill passed its House committee unanimously and then passed the full House 80-19 before heading to the Senate. BCPOA chairman Tom Fiddaman didn't mince words about what that meant for a district his association has represented since 1971: "HB 614 is a slap in the face to the citizens who initiated these districts by referendum," he said, adding that it "says that they can be terminated top-down with almost no due process."
Two more bills, Senate Bill 214 and Senate Bill 146, moved through the same session touching the same nerve, one on short-term rental classification and one on property rights appeals. As of the association's spring 2025 testimony, SB 214 remained without a scheduled hearing. None of this is settled history. It's a live fight over which rulebook a Bridger Canyon buyer will actually be operating under.
Why the Base Area Plays by Different Rules
Not every corner of the canyon carries the same restriction. The Bridger Bowl Base Area operates under its own plan, adopted separately from the general AE subdistrict, and its B4 zone is where the next change is already in motion. A text amendment filed by Bridger Pines would move Recreational Housing and Overnight Accommodations, essentially short-term rental classifications, from the zone's list of conditional uses to its list of permitted uses. If approved, that change means a permit for that use in the B4 zone wouldn't require a public hearing at all, which cuts both ways: fewer hurdles for an owner, less visibility for neighbors.
That distinction matters for anyone comparing a lot near the Bridger Bowl base to a parcel further out on Bridger Canyon Road or up toward Jackson Creek. The zip code is the same. The zoning subdistrict, and therefore what you can legally do with the property, is not.
What Due Diligence Actually Looks Like Here
None of this means Bridger Canyon is off the table for a buyer who wants rental flexibility. It means the due diligence has to go further than a listing description or a portal's "zoned residential" label.
- Confirm which subdistrict the parcel sits in, AE or the Base Area's B4 zone, since the rules genuinely differ between them.
- Ask whether the property already carries a Conditional Use Permit for a caretaker residence or guesthouse, and whether that permit's conditions say anything about occupancy or rental use.
- Check whether a Zone Text Amendment or Administrative Determination is pending for that specific parcel or zone, since both processes exist for adding short-term rentals to a district and either one can change the answer before you close.
- Treat any income projection built on short-term rental revenue as provisional until you've verified the current zoning status in writing, not assumed it from comparable listings elsewhere in the canyon.
The 40-acre minimum lot size that keeps Bridger Canyon rare, a limit built into the original plan specifically to limit population so that the capacity of the two-lane highway is not exceeded, is part of why land here carries a premium in the first place. That same regulatory document is what a buyer needs to read closely before assuming the premium comes with permission to rent it out.
Frequently Asked Questions
Does this rule apply to long-term rentals too? No. The silence-means-prohibition interpretation that county officials have described applies specifically to short-term rental use as defined in the zoning regulation. Long-term residential leasing is a different use category and isn't the subject of the enforcement actions or legislation described here.
If I buy a property with an existing short-term rental history, am I protected? Not automatically. The Lewis case shows that an existing caretaker residence or guesthouse permit doesn't grandfather in a short-term rental use if that use wasn't part of the original approval. Prior operation without a complaint isn't the same as compliance, as Wendy Dickson learned after operating for roughly two decades without incident.
Could the rules change again before I close? Possibly. Between the 2025 legislative session and county-level text amendments already in process for the Base Area, this is one of the more actively contested zoning questions in the Gallatin Valley right now. Verifying the current status at the time of your purchase agreement, not at the time you first toured the property, is the only way to know where things stand.
Bridger Canyon rewards buyers who do their homework before falling for the view.
