3101 21st St, San Francisco, CA 94110

The 30-unit, four-story apartment building at 3101 21st Street in the Inner Mission, owned by 1010 SVP Associates and constructed in 1998, has undergone several significant maintenance updates in recent years. Most notably, in 2024, a hot water heater was replaced, and in 2012, the building received substantial plumbing and electrical upgrades including the installation of two hot water boilers, replacement of a backflow device, and electrical improvements involving the replacement of light fixtures, ballasts, switches, and exit signs.

The building has been subject to routine safety inspections by Housing Inspection Services in 2015, and there have been multiple fire safety-related issues, with the most recent being a sleeping area requirement violation issued in November 2023. This violation remains open as of October 2023, while previous fire alarm system violations from 2018 and 2029 were successfully addressed.

The property has maintained basic compliance with safety inspections, though there have been recurring concerns about alarm systems and other safety features over the years, with most issues being resolved promptly. Recent 311 calls during late 2024 and early 2025 primarily relate to street cleaning and debris removal outside the building, while there are ongoing issues with graffiti on public fixtures and mailboxes near the property, though these external matters do not directly impact building residents.
