What it means for trades
A permit issued in December 2025 starts a clock. The early trades, site work, concrete, framing and structural steel, are bought in the next weeks; mechanical, electrical and plumbing a few months in; finishes and landscaping close to a year later on a typical build. Builtie tracks each project through those stages and shows it to a trade while its package is still open.
What the Seattle data covers
Seattle's feed rarely names the builder: 1.4% of new-build permits carry one. Builtie resolves the company behind a Seattle project from other records, and does not publish a Seattle builder count because it would describe the feed rather than the market.
