1641-1647 Noriega St, San Francisco, CA 94122

The Ng Family Revocable Trust owns this two-story, four-unit multi-family residential building with commercial space, constructed in 1951 at 1641-1647 Noriega Street in San Francisco's Central Sunset neighborhood. The property has undergone significant improvements and maintenance since 2002, with substantial commercial tenant improvements completed in 2012-2013 including accessibility upgrades, bathroom installations, and interior modifications totaling approximately $151,000.

Major infrastructure upgrades were completed in 2013, including a 400-amp electrical service upgrade with multiple meters installed, new central heating system, and plumbing work for accessible restrooms. More recent maintenance includes sewer line replacement work in 2018, indicating ongoing infrastructure upkeep. The building has experienced multiple waste management issues in recent months, with ten separate reports of abandoned garbage, debris, and electronic waste documented between November 2024 and January 2025, though all these cases were resolved by city authorities.

A street light outage was also reported and resolved in November 2024. While the property has maintained its structural and systems components through regular upgrades and repairs, the recent pattern of waste management issues suggests external environmental challenges in the immediate vicinity, though these are not directly related to the building's structural or systems conditions. Historical records show earlier improvements including ceiling framing replacement in 2003 and various unit remodels throughout the 2000s, demonstrating consistent property maintenance over time.
