1770 9th Ave, San Francisco, CA 94122

The 11-unit, 3-story multi-family residential building at 1770 9th Avenue in the Inner Sunset neighborhood, owned by the Sonia Apfelblum Trust, has undergone several significant safety and infrastructure improvements since its construction in 1962. Most notably, the building completed its mandatory soft-story retrofit in 2017 (Tier 3), which included an exploratory demo of stucco at the garage for framing verification. The property has maintained active fire safety compliance, with multiple upgrades to the fire alarm system between 2017-2018 to meet SF Fire Department requirements, including the installation of low-frequency sounders in sleeping areas and upgrading the fire alarm control panel.

The building experienced a significant fire incident in 2003 that required repairs to multiple systems, including electrical, HVAC, and plumbing, though these repairs were subsequently cancelled and completed under a different permit. Recent maintenance records show attention to building systems with water heater replacements (2017), window upgrades (2009), and electrical service improvements (2004). The building has faced some challenges with safety compliance, as evidenced by a cluster of fire safety violations in 2016 related to the alarm system, exits/fire escapes, sprinkler system, and combustible storage.

However, most of these issues were addressed promptly, with records showing "Condition Corrected" or "closed" status. The property has maintained an active record of addressing resident concerns, including electrical problems (2013), hallway lighting issues (2011), and recent plumbing concerns (2019). While there have been periodic issues with common area lighting, noise complaints, and some maintenance matters, the building has demonstrated a commitment to addressing these issues as they arise.
