Jed's answer below is a good one. You can also look online at
http://www.sfgov.org/dbi. You can also call them over the phone for the general process info. When I've called in the past, they suggested that I contact an architect who can put a plan together on what it is that I would like to have done so that it can be submitted to DBI for approval. Though a phone call may be easiest, you'll get more out of a direct visit to their offices.
