Montana FSBO Disclosure Requirements (2026)

Montana's Seller Property Disclosure Statement covers the primary disclosure requirements. Wildfire interface risk, well and septic infrastructure across rural Montana, spring flooding along Montana's rivers, and the right-to-farm agricultural neighbor context are the dominant local disclosure issues.

Montana SPDS Framework

MCA §70-16-701 et seq. requires the Seller Property Disclosure Statement. Sellers deliver to buyers before or at contract. Buyers have 3 business days to rescind after receipt. Montana's form covers structural conditions, well and septic, environmental hazards, flooding, and other material facts.

Wildfire Interface Risk Disclosure

Montana's forests — Douglas fir, lodgepole pine, ponderosa pine, spruce — create extensive WUI zones around western and central Montana communities. Major fire events affecting residential areas:

• 2000 fire season: One of the worst in Montana history, affecting large areas of western Montana
• 2017 fires: Lolo Peak Fire near Missoula, Rice Ridge Fire in Seeley Lake area
• 2021 Dixie Fire (California) context: Increased attention to WUI risk nationwide

Properties near Glacier National Park, the Bitterroot Valley, Flathead Valley, and many Bozeman and Missoula fringe communities are in WUI zones.

Montana SPDS wildfire section: Disclose proximity to wildfire risk areas and any prior fire damage to the property. Montana DNRC maintains wildfire risk maps.

Homeowner's insurance availability and cost in high WUI areas: Some Montana communities near forests have experienced homeowner's insurance availability challenges as carriers reassess wildfire risk. Buyers should be informed of this context.

Well and Septic in Rural Montana

Rural Montana residential properties use private wells and on-site septic almost universally outside municipal service areas. Even within city limits in smaller towns, well and septic may apply.

Well disclosure: Drilled well depth, pump age and type, last water quality test (full mineral panel recommended in Montana — naturally occurring arsenic, uranium, and other minerals are present in some Montana groundwater). Montana DNRC maintains well permit records.

Septic disclosure: Montana DEQ regulates on-site septic. Disclose system type, size, last pump-out, and any inspections. Some Montana septic systems are engineered solutions for challenging terrain (steep slopes, high groundwater, poor percolation soils).

Montana River Spring Flooding

Montana's rivers — Clark Fork, Blackfoot, Bitterroot, Flathead, Missouri, Yellowstone, Gallatin, Madison — typically experience peak flows in May and June during Rocky Mountain snowmelt. Flood zone properties are common in valleys and near river corridors.

FEMA flood maps for Montana: Check msc.fema.gov. Flooding during ownership must be disclosed on the Montana SPDS.

Agricultural Right-to-Farm Context

Montana's right-to-farm statute (MCA §27-1-725) protects agricultural operations from nuisance claims. For properties near active agricultural operations — farms, ranches, feedlots — neighbors cannot successfully sue for agricultural odors, dust, noise, or irrigation operations if the operation predates the residential development.

This is context for buyers, not a disclosure requirement per se. However, if your property is adjacent to an active farm, ranch, or other agricultural operation, disclosing the proximity and Montana's right-to-farm protection is good practice.

Montana No Transfer Tax

Montana has no real estate transfer tax. This is a meaningful cost difference compared to neighboring states and keeps Montana FSBO net proceeds higher than comparable transactions in higher-transfer-tax states.
