Seattle permit data, by use case

Same data, different angle. Pick the playbook that matches what you sell.

Real estate investors
Review published code-enforcement records with property context where linkage is available. A violation is a research signal, not evidence that an owner intends to sell.
Home service companies
An addition or remodel can be useful project context for HVAC, plumbing, or warranty outreach. Review the project signal before outreach.
Solar installers
Roof permits and electrical upgrades in Seattle provide project context for solar-market research. Filter by the current project signal and verify ownership separately.
Insurance agents
Seattle renovations can identify properties for a policy-review workflow. Confirm coverage needs independently before contacting a property owner.
Material suppliers & manufacturer reps
Choose a product-line research workflow, then use published job type, description, and value fields where available for territory and demand research. A permit is not a materials order, purchase signal, or open bid.
Developers & new construction
Sort source-published new-construction records by project value and type to research active projects and property activity.
