The Flood Mansion was the only great Nob Hill house to survive the 1906 Fire, saved just barely by its Connecticut brownstone walls. The Pacific Union Club purchased the shell, and William Bourn, who was on the building committee, secured the reconstruction commission for Willis Polk.

The Flood Mansion remains the home of the Pacific Union Club and is decidedly not open to the public. Not ever. Not under any circumstances. It is barely open to the wives of the members.

The Flood Mansion is also National Register Listing #66000230.
