50-54 Castle St, San Francisco, CA 94133

The three-unit multi-family residential building at 50-54 Castle Street in Telegraph Hill, owned by the Jonathan Dreyer Revocable Trust, has a documented history dating back to its 1906 construction. The most recent significant maintenance work was completed in 2018 with the issuance of a $5,900 reroofing project.

The building underwent routine housing inspections in 2001, 2005, and 2009, all of which were resolved and marked as not active. While no serious violations or safety concerns were noted in these inspections, they indicate regular oversight of the property. The building has experienced some infrastructure challenges over the past decade, particularly with wastewater systems, as evidenced by two sewage backup incidents in October 2016 involving a 4-inch vent, both of which were resolved through the PUC Sewer Operations.

A more recent incident occurred in October 2022 involving human or animal waste, though this was street-related rather than building-specific. The property's exterior areas have required attention based on 311 calls, including a general cleaning request in January 2014, which was resolved with the determination that the reported waste was not found. An older building permit from 1988 records work on kitchen cabinets, sheetrock, window sashes, and carpeting, though this permit is listed as expired and its completion status is unknown.
