3057 21st St, San Francisco, CA 94110

The two-story, four-unit multi-family residential building at 3057 21st Street in San Francisco's Inner Mission district, owned by Dima Tsenter, has undergone several significant improvements since its construction in 1963. Most notably, between 2019-2020, the property underwent substantial upgrades including a voluntary seismic upgrade with foundation work (cost: $50,000), proposed conversion of garage space to two ADU units, and a kitchen and bathroom remodel in Unit 1 ($35,000).

The building has had several maintenance and improvement projects over the years, including window replacements, dry rot repairs, and various structural improvements, with the most recent being a fire safety citation for blocked exits in October 2023 that was promptly corrected. The building's history reveals past concerns regarding maintenance and safety, particularly between 2007-2014, with multiple housing inspections revealing issues such as floor damage, ceiling problems, and dry rot.

There were also complaints in late 2013 about unauthorized remodeling work. More recently, in 2024, there have been some community service calls related to parking violations, encampments, and health concerns, though these appear to be more related to the building's location rather than the building's condition itself. The property has a documented history of tenant buyouts, with one recorded in November 2020 for $10,000.
