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.
Other building types in Seattle: residential renovation, commercial renovation, institutional renovation, industrial renovation.
