168-172 Hermann St, San Francisco, CA 94102

The 6-unit residential building located at 168-172 Hermann Street in Hayes Valley is a 2-story flats structure constructed in 1880, currently owned by Soong Lvg Tr. The building has undergone several significant maintenance and improvement projects over the years, with a particular focus on roof maintenance. Records show four consecutive reroofing projects between 2002 and 2017, with costs ranging from $3,000 to $8,800.

In 1990, major structural modifications were carried out including the demolition of exterior stairs to the second floor, window and door changes, and various framing revisions. More recently, in 2014, new gas piping was installed for water heater, furnace, and stove systems, though this permit is now expired. The building experienced a notable cluster of security and safety violations in December 2002, all of which were resolved by February 2003. These violations included the need for self-closing devices at exterior doors and the installation of a battery-operated smoke detector at the top of the public stairs.

Since then, there have been two routine housing inspections (2002 and 2008) that were marked as not active. The property has been subject to multiple 311 calls in recent years, primarily related to street cleaning and graffiti issues, with the most recent graffiti incident reported in February 2023. Several sidewalk cleaning cases were resolved between 2019 and 2022, and there was one reported instance of medical waste (needles) on the street in 2019 that was promptly addressed. A tree maintenance request from January 2019 received a response regarding the city's planting resources and permitting process.
