2341-2345 Polk St, San Francisco, CA 94109

The 8-unit multi-family residential building at 2341-2345 Polk Street in Russian Hill, owned by Henry C and Florence C Der, was constructed in 1923 and stands three stories tall. The building has undergone significant safety and maintenance upgrades in recent years, including a mandatory fire horn upgrade in 2024 ($43,194), electrical system improvements such as circuit breaker panel replacements and sub-panel updates, and seismic strengthening work including voluntary rear bay window reinforcement ($69,000) and completion of Tier 4 soft-story retrofitting. The property experienced a notable infestation of mice in early 2023, with complaints from multiple tenants about persistent rodent activity.

More recently, in 2023-2024, there were several compliance issues addressed including a boiler permit renewal matter and various building maintenance concerns, all of which were officially abated by October 31, 2023. The building's maintenance history shows regular updates to critical systems, including a new water heater installation in 2014 and multiple electrical system upgrades. Recent building permits indicate ongoing attention to structural elements, such as exterior stairs repairs due to dry rot completed in 2024 ($5,000).

The property has experienced multiple fire alarm system activations, though none resulted in injuries or confirmed incidents. A cluster of building violations from 2003, primarily related to heating system requirements, lead paint concerns, and stairs maintenance, were all abated by late 2023. The building's location has faced typical urban challenges, as evidenced by recent 311 calls regarding various municipal issues, including debris, tree damage, and environmental health concerns, though these are primarily external to the building itself. Separate inquiries regarding a possible basement illegal unit were documented in 2019, though this issue appears to have been resolved.
