Seattle's hilly terrain and constant moisture create a unique inspection environment. From craftsman homes in Queen Anne to mid-century ranches in West Seattle to new construction throughout the metro area, Seattle homes share common challenges dictated by the climate.

Moisture management dominates Seattle home inspections. The city sees 150+ days of measurable rain annually, and every component of a home must handle this exposure. Roofs, siding, windows, and drainage systems all face constant water contact. Inspectors look carefully for signs of water intrusion, failed flashing, and moisture damage.

Seattle's hills add complexity. Neighborhoods like Queen Anne, Magnolia, and Capitol Hill sit on slopes that create drainage challenges and can accelerate foundation movement. Retaining walls, drainage systems, and foundation condition require particular attention in hillside homes.

Crawlspace condition is a major concern in Seattle homes. Many older homes have inadequate vapor barriers, poor drainage, and ventilation issues that lead to moisture accumulation and wood rot. Crawlspace evaluation often reveals significant findings in Seattle inspections.

The city's housing stock includes beautiful craftsman homes from the early 1900s, but these often come with knob-and-tube wiring, galvanized pipes, and decades of moisture exposure. Understanding what's typical for Seattle homes helps buyers evaluate inspection findings appropriately.
