3970-3972 18th St, San Francisco, CA 94114

The two-unit residential building at 3970-3972 18th Street, owned by Albert Yip, is a two-story flats & duplex structure built in 1911 in the Eureka Valley/Dolores Heights neighborhood. The building has undergone several significant maintenance and improvement projects over the years, including a complete window replacement in 2004 ($8,375), back stair replacement in 2005 ($9,200), and a street space permit in 2016.

A 1991 roofing project is noted as expired in the records. The property experienced a series of fire safety-related violations in March 2002, including problems with egress obstructions and fire proofing materials, as well as a requirement to post gas meter instructional diagrams; all these violations were abated by April 25, 2002.

More recently, there has been an ongoing issue with graffiti at the property, with eight documented incidents between late 2023 and 2024, though most were classified as "Not Offensive." There was also a building complaint in 2005 regarding unauthorized construction of a deck where back stairs had been removed, and a routine apartment house inspection in 2009, neither of which resulted in significant ongoing issues. The most recent building-related service requests primarily concern graffiti and general street cleaning, with the most recent being an open graffiti case from December 2024, though these exterior issues do not directly affect the building's structural integrity or resident safety.
