15-17 Castle St, San Francisco, CA 94133

The three-unit, three-story multi-family residential building at 15-17 Castle Street in Telegraph Hill, owned by Aaron Peskin and Nan Shanahan, was constructed in 1906. The building's maintenance record includes significant work such as a $10,000 reroofing project completed in 2007 and house trap replacements completed in 2013.

Several housing inspections have taken place over the years, with a notable incident in 2005 when unauthorized windows were installed on the property line wall and an unpermitted rooftop deck was constructed, though these have since been resolved. The property has experienced recurring issues with waste management and public cleanliness in recent years, with multiple 311 calls between 2023-2025 reporting garbage and debris on the street and sidewalk.

A concerning cluster of medical waste (specifically needles) incidents was documented in July 2019, though these were promptly addressed by health authorities. A routine fire safety complaint regarding combustible materials was filed in September 2020 but was marked as a duplicate complaint and closed by November. The building's age and permit history suggest regular maintenance has been performed, though the frequency of recent waste-related complaints indicates ongoing challenges with street-level cleanliness in the immediate vicinity.
