Missoula County MT Homes for Sale

Missoula County covers about 2,600 square miles, and the City of Missoula is only a small piece of that. The city is the county seat and the only incorporated city or town in the county. Everywhere else is unincorporated, and the county commissioners provide the local government services. The county and city governments are separate, even though they share a name and work together on some projects.

The unincorporated communities include Lolo, Frenchtown, Seeley Lake, Clinton, Bonner, Milltown, East Missoula, Evaro, Huson, Turah, and the Swan Valley around Condon. Searching “Missoula County” instead of “Missoula” is how buyers see those places, and the answer to whether a home is in the city or the county decides a good deal of what comes next.

Water and sewer are address by address

Unlike the city, the county has no central water or wastewater system. Residents in some areas have formed Rural Special Improvement Districts to run their own. Lolo has one (RSID #901), and the county also lists districts for the El Mar area off Mullan Road, the Lewis and Clark area in Clinton, and the Sunset West area north of the Wye. Members pay for those systems through the special assessments table on the property tax bill, so ask for the tax bill early.

Outside any district, a house needs a well and a septic system, or a connection to the City of Missoula’s sewer. The city treats service as available when a line sits within 200 feet of the parcel boundary, and a parcel with available service has to connect when construction happens.

Permits before a build

The county’s online permit system handles address and approach permits as well as building and zoning permits, among others. The septic permit is separate: it goes through the Health Department and has to be finalized before the other permits can be issued. The Health Department requires groundwater monitoring to begin by April 1 where it applies, and four feet of separation between the drainfield and groundwater. Miss that April date and monitoring can wait until the next seasonal high-water period. Floodplain and shoreline permits are handled in person or by email at the planning office on East Main Street.

Zoning is also uneven. The county has 31 citizen zoning districts, each created at the request of the residents who live there. The county’s zoning map and property information system settle what applies to a specific parcel.

Questions about Missoula County homes

Is Missoula County the same as the City of Missoula?

No. The city is one place inside the county, with its own government. Homes outside city limits rely on the county for services and permits.

Will a home outside the city have city water and sewer?

Some do, through the city’s system or a special district. Others rely on a well and septic system. Check the property tax bill for special assessments, ask whether the home sits inside an RSID, and ask for the permit records on any well or septic system.

What does a new build outside the city need first?

A septic permit or a city sewer connection, because the septic permit has to be finalized before other permits are issued. Groundwater monitoring may be part of it, with a start date of April 1.

Which school district serves a county address?

It depends on the address. Missoula County Public Schools and the outlying districts each cover different areas, so confirm with the district.
