Weather and Building Across the State

Heat

Kennett and Caruthersville share the most hot days of all 141 Missouri places listed here: about 64 days a year at or above 90°F (NOAA normals, Blytheville Muni. Airport, AR station). 2 of 141 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

Maryville has the most freezing nights of all 141 Missouri places listed here: about 138 nights a year at or below 32°F (NOAA normals, Maryville 2E, MO station). 7 of 141 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. St. Joseph and Savannah share the most snowfall of the 43 listed Missouri places with this figure: about 21 inches of snow a year (NOAA normals, Troy 3N, KS station). 2 of 43 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.

Rain

Poplar Bluff and Dexter share the most precipitation of all 141 Missouri places listed here: about 51 inches of precipitation a year (NOAA normals, Poplar Bluff Muni. Airport, MO station). 34 of 141 listed places get 46 inches or more, or 12 or more days with an inch, so firm ground for units and ADA routes matters.

New and Older Housing

Wentzville has the highest share of recent housing of the 112 listed Missouri places with this figure: 39.9% of housing units built in 2010 or later (ACS 2020–2024). 37 of 112 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. St. Louis has the oldest housing of all 141 Missouri places listed here: a median year built of 1939 or earlier (ACS 2020–2024). 49 of 141 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): Mixed-Humid (134), Cold (7). A state spanning several regions means the right advice depends on the city, which is why each city page has its own figures.

Who Handles Event and Street-Use Rules

Of the 141 Missouri places listed here, 128 are incorporated cities, towns, villages or boroughs and 13 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 town or township it sits in, or the county. We do not say whether a permit is needed; each city page names who to ask.

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