175 Castro St, San Francisco, CA 94114

The two-story, four-unit multi-family residential building at 175 Castro Street in Duboce Triangle, owned by Antonia & Dolores M Loprest, was constructed in 1954. The property's significant historical modifications include the documented removal of an illegal fifth unit in 1989, which was accomplished by removing a kitchen.

In 2016, the building underwent reroofing work valued at $9,320, and in 2004, one wood window was replaced with vinyl at the rear of the building. The property experienced notable safety and compliance issues in 2001, when multiple violations were documented including the need for guardrails, proper fire extinguishers, and building permits; all these violations were abated by October 22, 2001. More recent concerns include several maintenance issues from 2007, particularly regarding problematic steps leading to a deck and recurring mold problems in a closet, though these were resolved by December 2007.

Routine inspections occurred in 2001 and 2011, with no significant ongoing issues noted. The building's immediate surroundings have experienced recent challenges including multiple reports of graffiti and one instance of loose garbage in late 2023, though these were handled promptly by city services. While the building's documented history shows a pattern of permit-related issues in the late 1990s and early 2000s, there have been no recent building code violations or safety concerns on record since 2011.
