Augrented Insights Report

The 11-unit, 3-story apartment building at 1741-1755 Polk Street in Nob Hill, owned by Harry Y S & Wen H Hsia Revo, has undergone several significant safety improvements and faced various maintenance challenges since its 1910 construction. Most notably, the building completed its mandatory soft-story retrofit program as a Tier 4 property, with work completed and Certificate of Final Completion issued.

Recent fire safety improvements include the September 2023 completion of fire alarm system upgrades and corrections of previous violations, as well as the installation of low-frequency sounders in 2022 to meet fire code requirements. The building has a history of plumbing and electrical improvements, including restroom upgrades in 2017 and various unit renovations between 2007-2008. Historical violations from 2003-2004 related to fire safety, lead paint concerns, and weatherproofing issues were all resolved by September 2004.

More recent history shows recurring fire alarm system issues, with violations addressed in 2024, though a new violation was issued in August 2024. The property has experienced periodic challenges with waste management, as evidenced by multiple 311 calls regarding garbage and debris between late 2024 and early 2025, though these are primarily external to the building. The most recent maintenance work completed includes the recommencement and completion of previously approved building permits in September 2023, totaling approximately $67,500 in improvements.
