970-974 Hayes St, San Francisco, CA 94117

The 3-unit, 3-story multi-family residential building at 970-974 Hayes Street in Alamo Square, owned by Danaus F. Chang and Sha Parker, was constructed in 1900 and has undergone several significant improvements over the years. Most notably, in 2010, the building received a comprehensive fire safety upgrade including a new alarm control panel, multiple horn/strobes, smoke detectors, heat detectors, and manual pull stations, though some related permits later expired.

The property was also the subject of important infrastructure work, including sewer line and house trap replacement in 2008 and electrical system upgrades including overhead service pipe and feeder replacement in 2010. The building's compliance history shows earlier challenges with housing safety, particularly evident in a series of violations documented between 2002-2009, which included issues with fire safety equipment, security features, and illegal room configurations. These violations were all officially abated by June 2009, following a combination of routine inspections and necessary remediation work.

More recent maintenance issues have been relatively minor and primarily focused on external matters such as street space permits, sidewalk repairs, and occasional exterior graffiti (last reported in 2015). The most recent inspections of record occurred in 2012 and 2018, with no active violations or complaints noted since 2009. Recent external maintenance concerns have been limited to routine urban maintenance issues such as waste management and sidewalk cleaning, with the most recent service calls for hazardous materials and toter management occurring in 2020-2021, all of which have been resolved. The building's ownership and management structure appears stable, with no recorded tenant buyouts or significant ownership changes in recent years.
