Weather and Building Across the State

Heat

Lamar has the most hot days of all 113 Colorado places listed here: about 82 days a year at or above 90°F (NOAA normals, Lamar Muni. Airport, CO station). 10 of 113 listed places reach 90°F on 60 or more days a year, and 4 average 10 or more days at 100°F. For most of the state, heat is a summer-month issue rather than a constant one.

Freezing Nights and Snow

Avon has the most freezing nights of all 113 Colorado places listed here: about 248 nights a year at or below 32°F (NOAA normals, Vail, CO station). All 113 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. Craig has the most snowfall of the 74 listed Colorado places with this figure: about 113 inches of snow a year (NOAA normals, Hayden, CO station). 68 of 74 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.

Rain

Boulder, Longmont, Estes Park and 1 other listed place share the most precipitation of all 113 Colorado places listed here: about 34 inches of precipitation a year (NOAA normals, Boulder 14 W, CO station). None of the listed places reaches the wet band (46 inches or 12 days with an inch), so rain is a day-of-event issue rather than a seasonal one.

New and Older Housing

Dacono has the highest share of recent housing of the 84 listed Colorado places with this figure: 47.5% of housing units built in 2010 or later (ACS 2020–2024). 43 of 84 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. Trinidad has the oldest housing of the 110 listed Colorado places with this figure: a median year built of 1953 (ACS 2020–2024). 12 of 110 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 (107), Very cold (3), Mixed-Dry (3). 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 113 Colorado places listed here, 77 are incorporated cities, towns, villages or boroughs and 36 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.
