2981-2983 21st St, San Francisco, CA 94110

The property at 2981-2983 21st Street, a 1900-built, two-story multi-family residential building in the Inner Mission, has undergone significant transformations in recent years, with particular focus on safety and modernization upgrades. Most notably, in 2021 a fire sprinkler flow monitoring system was installed, following the 2020 installation of a comprehensive fire sprinkler system for a newly added ADU (Accessory Dwelling Unit) in the garage area, which was part of a larger $198,000 renovation project that included foundation replacement and structural upgrades.

The property underwent several major modifications between 2019-2021, including the conversion to a four-unit building, electrical rewiring, and garage level revisions to add washer/dryer hookups and relocate utilities. The building's recent history shows substantial investment in improvements, with all permits from 2019-2021 marked as complete, including significant plumbing and electrical work.

However, the property faced considerable challenges in early 2019, experiencing multiple inspection issues related to vacant building status, plumbing problems with reports of sewage incidents, electrical safety concerns regarding extension cords between floors, and evidence of possible squatting. These issues were addressed through subsequent renovations and improvements. Recent 311 calls show ongoing maintenance needs in the area surrounding the building, with the most recent issues reported in 2023-2024 including graffiti, waste removal, and sidewalk cleaning needs, though these are primarily external to the building itself.
