King County Community Service Center - Black River

The King County Community Service Center at Black River sits at 919 SW Grady Way in the heart of Renton's civic corridor, just a short drive from the Green River Trail. Run by King County, this service center accepts passport applications on a walk-in basis Monday and Tuesday from 8:30 a.m. to 4:00 p.m. — no appointment required during those windows, making it one of the more accessible options in the South King County area.

Staff at the Black River center process new adult passports, first-time applicants, and applications for minor children. Because this is a county-run facility rather than a post office, you may find shorter queues than at busier USPS locations on the eastside. Bring your completed DS-11 form, proof of U.S. citizenship, government-issued photo ID, and the required fees in the correct payment form.

Renton sits in King County, about 12 miles southeast of downtown Seattle. Applicants who need travel documents urgently can visit the Washington state passport guide for details on the Seattle Passport Agency appointment process.

Walk-in service is available Monday and Tuesday only — arrive early, as slots can fill by midday. Bring your own completed DS-11 form (available at travel.state.gov), original proof of citizenship, valid photo ID, and the government fee by check or money order payable to the U.S. Department of State. A separate acceptance fee is paid to King County. For applicants planning ahead, the Renton passport offices page lists all local acceptance sites so you can choose the one that fits your schedule.
