Based on regional construction history and climate, home inspectors in Portland Or frequently report these issues.
Western Washington's wet, cool climate makes moisture management the central challenge of home ownership. Mold in attics, crawl spaces, and wall assemblies behind vinyl siding is extremely common. Seattle, Tacoma, Olympia, and Bellingham all have high ambient moisture conditions that require proper encapsulation of below-grade and unconditioned spaces.
Western Washington faces both shallow crustal earthquake risk (Seattle Fault, South Whidbey Island Fault) and potential Cascadia Subduction Zone events. Soft-story construction, cripple walls, and unreinforced masonry in Seattle's older neighborhoods are significant concerns.
Seattle's steep terrain, saturated hillside soils, and legacy bluff construction create significant landslide risk. Queen Anne Hill, Capitol Hill, West Seattle bluffs, and numerous other hillside neighborhoods have active landslide inventory. Lot topography and soil stability are important pre-purchase considerations.
Synthetic stucco failures in western Washington's wet climate have been well-documented. Any EIFS-clad home should receive a moisture probe inspection. Cedar and stucco homes from the 1980s–2000s with poor window flashing integration are a recurring problem.
Washington homes with vented crawl spaces in the wet Western WA climate accumulate high humidity, mold, and wood decay at accelerated rates. Fully encapsulated and conditioned crawl spaces are increasingly the standard repair recommendation. Fiberglass batt insulation against the joists is particularly prone to retaining moisture.
