What We Inspect During a Seattle Structural Inspection
At Puget Sound Engineering, our licensed professional engineers provide comprehensive Seattle structural inspections designed to uncover hidden issues, prevent future problems, and ensure compliance with local building codes. Below are the key areas we evaluate during a typical inspection.
Foundation Cracks and Settlement in Seattle
We assess hairline cracks, step cracks in masonry, and signs of foundation settlement. These may be caused by shifting soils, seismic activity, or improper drainage—issues frequently seen in the Puget Sound region. We determine whether a crack is purely cosmetic or structurally significant.
Moisture, Drainage, and Crawlspace Conditions
Due to Seattle’s heavy rainfall and high groundwater, moisture intrusion is a leading cause of structural damage. We check crawlspaces, basements, and perimeter drainage for standing water, wood rot, mold growth, and efflorescence on concrete surfaces.
Load-Bearing Walls, Beams, and Columns
We verify which walls are load-bearing and inspect beams and columns for signs of sagging, undersizing, or deterioration. This is especially important if you plan a remodel, wall removal, or open-concept conversion.
Retaining Walls and Slope Stability in Seattle Neighborhoods
Seattle’s hilly terrain makes retaining wall inspection essential. We check for leaning walls, cracking, inadequate drainage, and soil erosion that could lead to slope failure.
Floor Level Measurements and Settlement Mapping
Seattle’s hilly terrain makes retaining wall inspection essential. We check for leaning walls, cracking, inadequate drainage, and soil erosion that could lead to slope failure.
How Seattle Codes Affect Structural Inspections
Our inspections follow the Seattle Department of Construction & Inspections (SDCI) requirements and the Seattle Residential Code, which incorporates the International Residential Code (IRC) with local amendments.
Relevant Seattle Residential Code Requirements
Seattle’s high seismic risk requires specific detailing for foundations, shear walls, and connection hardware to meet code standards.
Local Soil, Rainfall, and Seismic Considerations
While Seattle’s snow load is moderate, the building code mandates proper design for wind uplift and lateral loads from seasonal storms.
Special Considerations for Older Seattle Homes (1920s–1980s)
By combining engineering expertise with local code knowledge, Puget Sound Engineering ensures that every recommendation we make is both structurally sound and Seattle-compliant.

Seattle Structural Inspection FAQs
A Seattle structural inspection by a licensed professional engineer includes a detailed evaluation of your home’s foundation, crawlspace, load-bearing walls, beams, columns, and structural connections. We check for cracks, settlement, moisture damage, and seismic vulnerabilities in compliance with Seattle building codes.
A home inspector provides a general overview of your property, while a structural inspection focuses specifically on the safety and integrity of the building’s structure. Our inspections are performed by licensed engineers who can diagnose the cause of structural issues and recommend code-compliant solutions.
Yes. Unlike many inspectors, we physically enter crawlspaces to assess the condition of foundation supports, posts, piers, beams, and joists. This ensures we find issues like hidden wood rot, moisture intrusion, or soil movement that aren’t visible from above.
Yes. Every inspection includes a detailed, engineer-signed report with photos, descriptions of any structural concerns, and recommended next steps. Reports are often ready within 1–3 business days.
Pricing depends on the size, age, and complexity of the property. For most Seattle homes, costs range from $500 to $800. Contact us for a free quote based on your specific property and inspection needs.
