3017 20th St, San Francisco, CA 94110

The three-unit multi-family residential building at 3017 20th Street in San Francisco's Inner Mission neighborhood, owned by Dominador V Ballesteros, has a significant and concerning history since its construction in 1900. Most recently, in January 2023, the building experienced major structural fire damage, leading to active code enforcement proceedings.

The building has faced multiple serious safety and habitability issues in recent years, including numerous violations filed in January 2017 relating to sanitation, heating, fire safety, security requirements, and water heater problems, many of which remain active or were only recently addressed. A concerning pattern of maintenance and safety issues is evident throughout the building's history, including problems with heating systems, fire safety compliance, and structural elements like stairs and decks. The building's documented history shows recurring issues with basic maintenance and safety requirements.

In 2021, a water heater replacement was attempted, though the permit ultimately expired, and previous permits show various repairs and improvements ranging from deck replacement (2009) to fire damage repairs (1999). More recent concerns include sewage back-up discharge incidents reported in November 2024, multiple fire code violations documented in 2023, and a history of pest infestations and sanitation problems as evidenced by multiple complaints and violation notices. The property has undergone several important repairs and improvements over the years, including closet installations (1994), window and door work (1984), and various code compliance measures (1983), but persistent maintenance issues suggest ongoing challenges with building upkeep and habitability standards.
