101-109 21st Ave, San Francisco, CA 94121

The two-story, ten-unit multi-family residential building at 101-109 21st Avenue, built in 1917 and currently owned by Ford Trust, has undergone significant safety and infrastructure improvements in recent years. Most notably, in 2023, the building completed a comprehensive upgrade to its fire alarm system to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and new compatible devices. The building also completed a mandatory soft-story retrofit in 2017 to improve seismic safety, demonstrating compliance with San Francisco's building safety requirements.

Electrical infrastructure improvements are ongoing, with a new main service disconnect installation scheduled for July 2024, following previous updates including kitchen rewiring work in 2020 and a new subpanel installation in 2023. Recent maintenance issues have been documented, including leaks and water-related problems. In 2023, complaints were filed regarding mold, mildew, and window leaks, and more recently in September 2024, additional kitchen leak complaints were recorded.

The building's history includes a set of violations from 2004 related to ventilation, fire safety, and plumbing issues, though these were all abated by June 2004. The property has maintained regular inspections and undergone various infrastructure improvements over the years, including a house trap replacement in 2021 and water service upgrades in 2018. Recent 311 calls between 2024-2025 primarily relate to parking enforcement and street cleaning issues outside the building, rather than internal building concerns. While a sprinkler/standpipe systems complaint was made in August 2023, it was determined to have "No Merit" or was "Condition Corrected" according to fire records.
