As defined by the San Francisco Building Code, a sub-sidewalk basement is that part of the underground building structure which extends into the public right of way.
Both the Department of Building Inspection (DBI) and the Public Works are responsible for different parts of the sub-sidewalk basement process.
A banner permit grants permission to temporarily occupy any City-owned utility poles (primarily poles with streetlights but no utility wires) for the purpose of providing notice to residents and visitors of San Francisco about City-sponsored, City-funded, City-wide special events and locations of the City's diverse neighborhoods.
