# Big Buildings Washington United States - Clay 2026

87,000 leads, emails not included so you enrich them yourself · Free

87,000 large commercial buildings across Washington state, built in Clay for 2026. Every row carries the property and the business detail attached; emails are not included, so you enrich the file yourself.

Who this is for: commercial cleaning and FM providers, HVAC and roofing contractors, energy-efficiency and retrofit firms, and building-security vendors.

Before you send: enrich and verify emails first. Washington has aggressive building performance standards with compliance deadlines attached, so retrofit and energy vendors should lead with the requirement rather than the product. Segment the Seattle metro from the rest of the state.
