Off-Grid Living in Meagher County, Montana

I'll be upfront: Meagher County, Montana is thin on published off-grid-specific rules, so a fair amount of this comes down to state defaults layered under a fairly minimal local government structure. Here's what I found digging into it.

Zoning. Meagher County doesn't appear to have a single, comprehensive countywide zoning ordinance on the books (at least not one I could confirm). Instead, planning runs through the joint Meagher County/White Sulphur Springs Consolidated Planning Board, a 7-member board appointed by the city, the county commissioners, and the local Conservation District. The county has adopted subdivision regulations, and those regulations, plus whatever specific zoning districts the Board has put in place, are likely what govern raw-land use outside city limits. If you're inside White Sulphur Springs itself, that's a separate, more built-out municipal code.

Dwellings, tiny homes, RVs. I couldn't find a Meagher County page addressing tiny homes or RV living directly. That means you're likely defaulting to Montana's state baseline, which uses IRC Appendix Q for foundation-built tiny homes and treats wheeled RVs under separate rules. Confirm current status with the county before assuming anything.

Building permits. This is one of the more interesting findings. Montana lets cities and counties opt into running their own certified building-code enforcement programs, but only a handful of counties (Missoula, Gallatin, and a few others) do. I found no evidence Meagher County runs its own program, which suggests unincorporated parts of the county fall under the state's Building Codes Program (Department of Labor & Industry) rather than a local building department. Montana law also exempts most single-family and duplex homes from state permit requirements, along with private garages and storage buildings, so a lot of small off-grid builds may not need a state permit at all. White Sulphur Springs, inside city limits, has its own separate building code.

Septic. This one's confirmed: Meagher County has a Sanitarian Services function, contracted out to Great West Engineering, that handles septic permits. Questions get routed through the Clerk & Recorder's office. This is the local face of the statewide DEQ/local-health-board septic system, so plan on a permit for any septic install.

Greywater, rainwater, wells. None of these have a Meagher County-specific page that I could find. They almost certainly default to state rules: Montana allows limited in-home greywater reuse without a permit, there's no state law blocking basic rooftop rainwater collection for non-potable use, and private wells fall under the state DNRC's exempt-well framework rather than any county water office.

Utility disconnection. No ordinance requiring hookup to grid power or municipal water/sewer for a private home outside city limits turned up in my research. Any such requirement would most likely come in through subdivision conditions or septic permitting, not a standalone "must connect" rule.

Bottom line: call ahead. This county runs lean, and a lot of what applies to you will be state rules filtered through a small local office.
