Hi, and welcome to OpenStreetMap!

Unfortunately, OSM and its individual contributors (like me) have no direct control over updating aerial imagery; we just have permission to use imagery provided by specific sources. It's likely that the imagery of this location available to OSM will not update for several years.

The latest aerial imagery of this location (provided by Bing) does show the under-construction houses, so I added the new houses with their approximate geometry based on the foundations visible in the imagery and added the addresses currently available from King County's Open Data Portal, including for the address you mentioned. (Changeset: 149836085)

Congratulations on your new home - and once these changes propagate to the data consumers, your address should be findable on OSM-based maps.

Thanks for bringing attention to this area in need of an update! Closing note.
