14-16 Castle St, San Francisco, CA 94133

The property at 14-16 Castle Street is a two-unit, two-story multi-family residential building located in Telegraph Hill, owned by Frances M. Pisciotta and Children. Built in 1932, this flats and duplex building has undergone several significant renovations over its lifetime.

Most notably, in 2020, the building received a comprehensive window upgrade with the installation of 21 new windows, including Marvin Ultimate aluminum-clad wood double-hung windows on the front facade, representing a $15,000 investment in improvements. The building's maintenance history also includes a reroofing project in 2010 ($6,500), emergency wooden stairs replacement in 1998, and substantial foundation work in 1997 involving both perimeter replacement and garage modifications. Recent records from late 2024 indicate a concerning pattern of sewer-related issues, with multiple reports of sewage discharge from the side sewer vent in November 2024, followed by additional sewer service requests in December 2024.

There have also been several reports regarding garbage and debris management, including abandoned items and improper toter placement, though most of these have been resolved through outreach or inspection. The building's historical permits show significant structural work was done in the late 1990s, including foundation repairs and installation of plywood walls, suggesting earlier maintenance challenges were addressed at that time. The property has maintained active permit records, with the most recent work concentrated on window upgrades that enhance both the building's aesthetics and energy efficiency.
