152-158 Pfeiffer St, San Francisco, CA 94133

The Woo Family Trust owns this 2-story, 4-unit multi-family residential building located at 152-158 Pfeiffer Street in Telegraph Hill, which was constructed in 1907. The building has undergone several significant fire safety updates in recent years, most notably a complete fire alarm system upgrade in December 2024 costing over $29,000, following a cancelled $40,000 upgrade attempt in March 2024.

The fire safety improvements include the installation of low-frequency sounders in sleeping areas and updating existing devices to be compatible with the new fire alarm control panel, as confirmed by an electrical permit issued in August 2024. The building had a series of violations in September 2005 that were all addressed and abated by December 2005, including issues related to smoke detectors, the central alarm system, fire extinguishers, wooden stairs, and gas utility shutoff requirements. More recently, the property has experienced some exterior maintenance challenges, with multiple pavement defects reported in 2023, and instances of construction equipment blocking the sidewalk in August 2023.

The most recent issues appear to be primarily related to street infrastructure rather than the building itself. The building's history includes routine inspections dating back to 2001, 2005, and 2010, all of which were resolved, and various 311 calls regarding the surrounding area, including parking enforcement and street cleaning matters. The property has demonstrated ongoing commitment to fire safety upgrades, as evidenced by the recent fire alarm system improvements.
