    A 68-year-old S.F dim sum institution will close its largest location — San Francisco Chronicle

DBI holds 447 permits for this parcel, most of them tenant improvements on individual floors. The timeline shows the 24 largest by stated cost, plus the earliest on file; the DBI query in the sources below returns all 447. 17 of them are nominal $1 street-space or sidewalk permits. 3 expired or cancelled permits are not shown. The assessor dates this parcel to 1925; the Rincon Annex post office at the heart of the complex opened in 1940 and the surrounding redevelopment was finished in 1988.

Refregier's murals

Anton Refregier won a federal competition in 1941 to paint the lobby of the Rincon Annex post office and was paid $26,000 for 27 panels on the history of California and San Francisco. The Second World War interrupted the work; he resumed in 1946 and finished in 1948. In 1953 a congressional hearing considered removing the murals as inconsistent with American ideals and principles. They stayed.

The Rincon Annex was listed on the National Register in 1979 and made a San Francisco landmark in 1980. Doug Hollis's Rain Column, installed with the 1988 redevelopment, drops water 85 feet from a ring beneath the atrium skylight.
