1458 20th Ave, San Francisco, CA 94122

The three-story, six-unit multi-family residential building at 1458 20th Avenue in the Central Sunset neighborhood was constructed in 1929 and has undergone several significant improvements over the years. Most recently, fire safety upgrades are underway, with permits issued in September 2024 for the installation of new low-frequency sounders in the fire alarm system, bringing the building into compliance with current fire department requirements.

The building has successfully completed its mandatory soft-story retrofit (designated as Tier 3), which was completed in 2016 at a cost of $61,000, including additional work to modify perimeter footings. Other notable improvements include the installation of a new steam boiler and water heater in 2017 ($15,000), window replacements in 2005 (64 units, $22,855), and roofing work completed in 2007 ($6,300). Historically, the building has experienced several maintenance issues that required intervention from housing inspectors, including past problems with heat supply (2000-2001), damaged ceilings (2000), and missing handrails on back stairs (2002), though all these violations have been abated and are no longer active.

The property has also experienced recurring parking enforcement issues in recent months, with multiple citations issued for blocked driveways between May 2024 and January 2025, though these are external to the building's operations. The building's systems have received regular attention, as evidenced by various permits for electrical upgrades, including a foundation ground electrode installation in 2016, and maintenance work such as garage door opener replacement in 2009. While the building's history shows some past maintenance challenges, recent improvements and regular system upgrades suggest ongoing management attention to building safety and habitability requirements.
