The 3-unit, 3-story multi-family residential building at 3350-3354 24th Street in the Inner Mission, owned by the Jeffrey K Schalk Living Trust, was built in 1900 and is classified as a TIC building with 4 units or less. The property has undergone significant safety system improvements over the past decade, with major work completed in 2017 including the installation of a new fire control panel, heat detector, pull station, and integration of a sprinkler waterflow supervisory system at a cost of $3,000.

This work was part of a larger fire safety upgrade that began in 2013, which included the installation of numerous new wiring and safety components such as smoke detectors and sprinkler heads, demonstrating ongoing attention to life safety systems. The building has experienced several notable issues historically, including a significant fire incident in December 2011 that caused damage to multiple floors, though this was addressed and abated by February 2014.

Several construction-related complaints were filed in 2012-2013 regarding unauthorized work and modifications, including concerns about an elevator shaft installation and lightwell infill, though these issues appear to have been resolved. The building's infrastructure has seen substantial upgrades, including the installation of solar panels in 2012 and various electrical system improvements between 2004-2012. Recent maintenance and safety inspections indicate ongoing attention to building systems, with electrical and plumbing systems receiving particular focus throughout the building's maintenance history.
