2021-2023 Polk St, San Francisco, CA 94109

The three-story, six-unit multi-family residential building at 2021-2023 Polk Street in Nob Hill, owned by Rose Wing Properties, has undergone several significant improvements since its construction in 1908. Most notably, the building completed a mandatory soft story retrofit in 2018 at a cost of $80,000 to comply with 2016 seismic safety requirements, achieving Tier 4 status with Certificate of Final Completion issued. Recent upgrades include electrical work in 2020 replacing the sub-panel and installing new lights and outlets, and multiple sewer-related service requests in 2023 and 2024 regarding missing vent covers.

The building's maintenance history shows attention to major systems, with a 2011 reroofing project ($17,500), a $30,000 interior remodel in 2010 including structural repairs, and plumbing updates including a new sewer lateral installation. The property has experienced some challenges, particularly in 2009 when multiple housing violations were documented, including issues with floor coverings, windows, kitchen cabinets, electrical systems, security hardware, fire safety (fire extinguisher maintenance), and heating system requirements. All these violations were officially abated by June 2012. The building has also had isolated incidents of building complaints, including a 2019 complaint about late-night construction noise from an adjacent property.

While there have been minimal fire incidents recorded (two in 2011 - one being an unintentional smoke detector activation and another regarding hazardous materials that was promptly corrected), these are not necessarily indicative of ongoing safety concerns. The surrounding area has seen regular city service interactions, primarily related to street cleaning and waste management, as reflected in multiple 311 calls between 2022 and 2024, though these issues appear to be promptly addressed. The building's recent history shows consistent attention to structural integrity and systems maintenance, with the most significant historical issues having been resolved. The property has met current seismic safety requirements through the completed soft story retrofit, and regular maintenance and upgrades suggest ongoing investment in the building's systems and infrastructure.
