Accommodations for People with Disabilities
If you have a disability, you may request an accommodation by completing a Request for Reasonable Accommodation form. Instructions are included with the form.

Due to the steepness of the streets around the courthouse and the dearth of on-street parking, most people with disabilities who visit the courthouse have someone drop them off at the facility's Third Avenue entrance. Limited disability parking is available on Dilling Way, just south of the Courthouse, but this parking often is full. If you are fortunate enough to find parking there, you may wish to cross the street to the King County Administration Building, where you can take an elevator down to the basement level and pass through a tunnel into the Courthouse. One final option is to use public transit (e.g., an accessible bus) to come to the courthouse.

Security Screening
You will pass through a security screening station as you enter the courthouse. Please take a moment to learn about the items prohibited from King County court facilities. Watch a video describing security screening at courthouse entryways.

Childcare is not available at the King County Courthouse.

There is a snack shop on the first floor of the courthouse, and vending machines are available in the jury assembly room on the first floor. Many restaurants are close by.
