Weather and Building Across the State

Heat

Kennewick, Pasco, Richland and 1 other listed place share the most hot days of all 189 Washington places listed here: about 55 days a year at or above 90°F (NOAA normals, Pasco Tri Cities Airport, WA station). None of the 189 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

Yakima, Toppenish, Selah and 2 other listed places share the most freezing nights of all 189 Washington places listed here: about 147 nights a year at or below 32°F (NOAA normals, Yakima Air Terminal, WA station). 22 of 189 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. Spokane, Spokane Valley, Cheney and 5 other listed places share the most snowfall of the 26 listed Washington places with this figure: about 45 inches of snow a year (NOAA normals, Spokane Intl. Airport, WA station). 13 of 26 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.

Rain

Aberdeen, Hoquiam and Ocean Shores share the most precipitation of all 189 Washington places listed here: about 69 inches of precipitation a year (NOAA normals, Hoquiam Bowerman Airport, WA station). 15 of 189 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

Tehaleh has the highest share of recent housing of the 163 listed Washington places with this figure: 92.6% of housing units built in 2010 or later (ACS 2020–2024). 94 of 163 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. Hoquiam has the oldest housing of the 188 listed Washington places with this figure: a median year built of 1939 or earlier (ACS 2020–2024). 19 of 188 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): Marine (154), Cold (35). A state spanning several regions means the right advice depends on the city, which is why each city page has its own figures.

Shoreline Places

34 of 189 listed places have a Census reference point within 5 km (about 3 miles) of the shoreline in the TIGER coastline layer, which includes Great Lakes shores. Beach and waterfront sites need a firm approach for trucks and a firm route for ADA units.

Who Handles Event and Street-Use Rules

Of the 189 Washington places listed here, 119 are incorporated cities, towns, villages or boroughs and 70 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.
