The three-unit multi-family residential building at 2824-2828 21st Street in San Francisco's Inner Mission neighborhood was constructed in 1910 and has undergone significant improvements over the past few years under the ownership of Mikhal Sofer 2017 Trust. Between 2018 and 2020, the property received substantial upgrades including the installation of a comprehensive fire sprinkler system throughout the basement and first floor ($19,494), a sprinkler monitoring system ($5,000), and a complete electrical service upgrade with new fixtures and safety features ($19,494). The building underwent significant interior improvements including kitchen and bathroom remodels in all three units, installation of new gas furnaces ($4,000), and gas meter relocation with protective cabinets ($4,000).

The property has a documented history of maintenance issues from early 2016, including complaints about inadequate heating, mold and mildew, plumbing problems, and window repairs. These violations were officially abated in June 2016. More recent maintenance work includes garage door replacements ($2,500) in 2020 and various interior and exterior improvements.

Planning records indicate approved projects for a roof deck addition, lightwell modifications, and basement garage improvements, demonstrating ongoing investment in the property's infrastructure and safety systems. The building has consistently addressed safety and compliance requirements, including a 2018 building fire investigation that resulted in no civilian injuries, though the ignition cause was undetermined. Recent 311 calls primarily relate to parking enforcement and street cleaning issues rather than building-specific concerns, suggesting improved property management and maintenance standards in recent years.
