Read October 9, 2026 from Builtie's permit data.
A month is marked incomplete when its count is under half of the market's usual month: that is the city's publishing lag, not a slowdown.
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.
Building types: new residential construction, residential renovation, commercial renovation, institutional renovation, industrial renovation. Every trade: Seattle construction leads by trade.
