Union Square

Established in 1999, the Union Square business improvement district (BID) was the first in San Francisco. The BID was originally set up for a five year period, then renewed in 2004 for another five years. The recent 10-year reauthorization of the BID greatly expanded the district’s boundaries, which now encompasses 2,980 parcels. The Union Square BID enhances the experiences of visitors to the area by continuing to provide the maintenance and public safety services originally offered. In addition, the BID will maintain Union Square’s standing as a premier retail, hotel and theater district and favorite visitor destination through marketing, advocacy and beautification programs.
