Condo Market in Seattle, WA
Median price, HOA fees, insurance, energy mandates, and hidden costs for Seattle condos in 2026.
Seattle Condo Market Overview
Washington State's Clean Buildings Performance Standard applies to commercial and multifamily buildings over 20,000 sq ft, with compliance deadlines beginning in 2026. Seattle's condo market also contends with the state's high construction costs, earthquake retrofit requirements for older buildings, and rapidly rising insurance premiums. The city's condo inventory has grown as developers pivoted to apartments, creating downward price pressure while carrying costs climb.
Energy Mandate Status
Deadline: 2026 (Tier 1), 2028 (Tier 2)
Condo buildings in Seattle must comply with WA Clean Buildings Act requirements. Non-compliant buildings face financial penalties that are passed through to unit owners as special assessments or HOA fee increases. Compliance typically requires HVAC upgrades, insulation improvements, window replacement, and potential electrification of building systems.
