Radon: Zone 2 — Moderate Risk· State-level data

Spokane's housing market is more affordable than the Seattle metro and has a different construction profile reflecting its inland location. The city has significant older inventory from the 1900s-1940s in historic neighborhoods like South Hill and Browne's Addition, with brick and wood-frame construction. Spokane's climate is more extreme than western Washington: colder winters with significant snowfall, hot dry summers, and dramatic temperature swings that stress building envelopes. Older homes have original cast iron plumbing, knob-and-tube wiring in many pre-1940 structures, and heating systems that must perform reliably in temperatures that regularly reach single digits. The area sits in a moderate seismic zone. Newer construction in Spokane Valley and Liberty Lake represents a growing portion of the market and has more conventional post-1990s wood-frame construction. There are 15 inspectors in the Spokane area.

Seasonal Inspection Tip for Washington
Spring Seismic and Structural Check on the West Coast

Spring is an ideal time for a West Coast seismic safety inspection. California, Oregon, and Washington homeowners should verify that their home has proper cripple wall bracing, anchor bolts, and water heater earthquake straps. Many homes built before 1980 have never been retrofitted.

Common Home Issues in Spokane, WA

Based on regional construction history and climate, home inspectors in Spokane frequently report these issues.

Mold — Puget Sound & Western WAhigh

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.

Seismic Risk — Puget Soundhigh

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.

Landslide Riskhigh

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.

EIFS & Stucco Moisture Retentionhigh

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.

Crawl Space Encapsulationhigh

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.
