Map of 543 Howard St.

In 2003, OSAF moved its offices to 543 Howard Street in San Francisco. Located between 1st and 2nd streets in the SOMA area, 543 is the first fully "green" office building in San Francisco. It is also a dog friendly building with a dog run on the roof and dog friendly lease terms. Visitors may be greeted by dogs at the elevator. If you are nervous around dogs please let your contact know in advance.
