Augrented Insights Report

The three-story, six-unit multi-family residential building at 301-311 Union Street in Telegraph Hill, owned by Dong Ventures Llc, was constructed in 1914 and has undergone several significant improvements and faced various challenges over its history. Most notably, the building completed mandatory soft-story seismic retrofitting in 2015, including the installation of hardy frame panels, with a final cost of $45,540. The property has seen recent fire safety improvements, including a 2021 upgrade to the fire alarm system with low-frequency sounders throughout sleeping areas to meet current safety codes. Maintenance issues have periodically emerged, including dry rot repairs in 2017 and plumbing work in 2016.

The building has experienced some concerning historical incidents, particularly in 2003 when multiple violations were recorded related to fire safety, security, and plumbing issues, though these were subsequently abated. A particularly notable complaint was filed in April 2019 regarding a suspected illegal rooftop unit with unauthorized utilities. Recent records show continued concerns about garbage management, with multiple overflow incidents reported through 311 calls between December 2024 and January 2025, though these pertain to city garbage cans rather than building-specific issues. The building's maintenance history shows regular attention to both structural and safety systems, with completed work including window replacements (2001), foundation repairs (2016), and the relocation of basement restroom plumbing (2016).

The property has experienced five documented fire-related incidents, though none resulted in civilian injuries. The building's overall record suggests active management with a focus on addressing both structural integrity through soft-story retrofitting and safety systems through fire alarm upgrades. While historical violations indicate periods of maintenance challenges, these appear to have been addressed through subsequent work and permit approvals. Recent improvements to safety systems and structural components suggest ongoing attention to building code compliance and resident safety.
