New building permits in King County, Washington show where construction activity is being recorded. Contractors can filter the available public records by trade, date, address, and project value to research projects and plan outreach using the fields the source publishes.
King County, Washington processes building permits covering residential construction, commercial buildouts, renovations, and specialty trade work. PermitGrab tracks 6,907+ King County building permits — newest permit date: 2026-11-05 from this listing's source.
Building permits in King County can document new construction, renovations, and specialty work. The fields in a public record vary by filing, but may include a project address, scope, estimated cost, or contractor name. Use the displayed source information to evaluate whether a record is useful for your market research.
HVAC contractors, electricians, plumbers, and roofers can use King County building-permit records to research visible construction activity. A permit may signal a project that is relevant to a particular trade, but the source record does not establish that its owner is seeking a bid.
Use the published date, project details, and any named business contact to research a project before outreach. Public records are not exclusive, and outreach results depend on the market, project, and your own process.
Eligible subscribers can receive trade-filtered alerts when new records are collected. Alert timing and field coverage follow the underlying source rather than a universal schedule.
PermitGrab methodology · Page data current as of · Source: 3 public source feeds.
PermitGrab indexes 6,907 building permits in King County. New records appear as they are available from the source.
The most recent permit indexed for King County is dated 2026-11-05. Newest permit date: 2026-11-05. Permit records carry filing date, address, project value, and permit type, plus contractor name where the source publishes it. Use a recent published record for project research; it does not show bid availability or a request for service.
King County permit activity covers 6,907 indexed permits. The records can cover new construction, residential renovations, mechanical/electrical/plumbing upgrades, roof replacements, demolitions, or tenant improvements. Their usefulness for a contractor or supplier depends on the published project details, timing, and service area.
Search a business name to review its recorded permit activity in King County and the project details the public source publishes. Use the scope, timing, and address to research complementary work; a record is not a request for bids.
