Thanks -- I wasn't sure so I just left it.

It's an office building with multiple tenants. I'm not sure who has moved into how much of the space they used to occupy upstairs.

According to https://kingcounty.gov/en/dept/local-services/certificates-permits-licenses/permits/permit-customer-services it looks like they moved to:
919 SW Grady Way, Suite 300, Renton WA, 98057
But I've not confirmed it in person.
