District 4 consists primarily of the Sunset district. Incumbent supervisor Katy Tang ran in her first election after being appointed by Mayor Ed Lee in the wake of Carmen Chu's resignation to be San Francisco Assessor-Recorder.
Proposition B would create a special district at 8 Washington Street, allowing for the development of residential units and commercial facilities with higher building height limits than currently zoned. Unlike Proposition C below, this measure is a ballot initiative filed by the project developer incorporating certain details of the entire project beyond building height limits.
Proposition D would make it City policy to utilize all available opportunities to lower the City's cost of prescription drugs and to ask state and federal representatives to sponsor legislation to reduce drug prices paid by the government.
