427-429 Frederick St, San Francisco, CA 94117

The three-unit multi-family residential building at 427-429 Frederick Street, owned by the Jerold B Balzer Trust, was constructed in 1912 and is a three-story flats and duplex structure located in the Parnassus/Ashbury Heights neighborhood.

The property has experienced several significant maintenance and safety issues, most notably in April 2017 when multiple building violations were recorded including problems with weather proofing, window repairs, interior surface maintenance (ceiling painting and floor covering), and fire safety compliance (fire extinguisher requirements and smoke/carbon monoxide alarm certifications). A concerning pattern of deterioration was documented in April 2017, including reports of water intrusion, potentially hazardous lead paint conditions, and electrical issues with sparking outlets.

The building underwent a street space permit issuance in January 2010, and while there have been some recent 311 calls regarding the property (including instances of abandoned furniture in 2024 and sidewalk graffiti in 2019), these issues appear to be relatively minor compared to the 2017 violations. Historical records show regular routine inspections in 2003, 2011, and a series of complaints from 2017 that were subsequently abated by July 2017, suggesting that many of the documented violations were addressed within a reasonable timeframe.
