Weather and Building Across the State

Heat

Miles City has the most hot days of all 27 Montana places listed here: about 41 days a year at or above 90°F (NOAA normals, Miles City F Wiley Field, MT station). None of the 27 listed places reach 90°F on 60 or more days a year. For most of the state, heat is a summer-month issue rather than a constant one.

Freezing Nights and Snow

Butte has the most freezing nights of all 27 Montana places listed here: about 220 nights a year at or below 32°F (NOAA normals, Butte Bert Mooney Airport, MT station). All 27 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. Great Falls has the most snowfall of the 6 listed Montana places with this figure: about 66 inches of snow a year (NOAA normals, Great Falls Intl. Airport, MT station). All 6 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.

Rain

Helena, Helena Valley Northwest, Helena Valley Southeast and 1 other listed place share the least precipitation of all 27 Montana places listed here: about 11 inches of precipitation a year (NOAA normals, Helena Regional Airport, MT station). 19 of 27 listed places get under 15 inches a year: firm, dry ground, but wind and dust on open sites, so ask for units to be staked.

New and Older Housing

Belgrade has the highest share of recent housing of the 22 listed Montana places with this figure: 36.2% of housing units built in 2010 or later (ACS 2020–2024). 13 of 22 listed places are above the U.S. share of 11.4%. That describes the housing stock, not current permits, but it shows where new-home construction has been concentrated; OSHA's toilet table applies to every one of those job sites. Anaconda-Deer Lodge County, Livingston and Lewistown share the oldest housing of all 27 Montana places listed here: a median year built of 1954 (ACS 2020–2024). 7 of 27 listed places have a median year built of 1970 or earlier, where renovation crews in existing buildings are the usual job site.

Climate Regions

Listed places by DOE Building America climate region (county-level, PNNL guide to IECC 2021 zones): Cold (27). Winters in this region are long enough that freezing, not heat, is usually the main limit on units that carry water.

Who Handles Event and Street-Use Rules

Of the 27 Montana places listed here, 19 are incorporated cities, towns, villages or boroughs and 8 are Census-designated places, unincorporated communities without a municipal government. The rule of thumb for an event on public land or a unit on a street or sidewalk: in an incorporated place, ask the city, town, village or borough government; in an unincorporated community, ask the county. We do not say whether a permit is needed; each city page names who to ask.

2 listed places are independent cities or consolidated city-counties, where one government handles both city and county matters.
