1406-1408 21st Ave, San Francisco, CA 94122

The property located at 1406-1408 21st Avenue in the Central Sunset neighborhood is a three-story, two-unit multi-family residential building constructed in 1937, currently owned by Shdj Trust. The building has undergone significant improvements and modifications over the past few years, most notably the addition of an accessory dwelling unit (ADU) at 1406A, completed in 2022, and a substantial garage-level unit conversion in 2020 that included a soft-story retrofit costing $80,000.

Major safety enhancements were implemented with the installation of a comprehensive fire sprinkler system throughout the building in 2020-2021, at a cost of $36,000, along with associated fire safety infrastructure. Recent improvements have focused on unit upgrades and modernization, including bathroom additions in both units (2021-2022), electrical system upgrades with new 200-amp service installation (2020), and comprehensive plumbing improvements including complete repiping of the house in 2011.

The property has experienced several maintenance-related issues in recent years, particularly regarding waste management, with multiple reports (April-May 2023) concerning toters being left out continuously, though these were generally resolved through city departments. The building's maintenance history shows regular updates to essential systems including plumbing (water heater and furnace replacement in 2019) and electrical systems, with most recent work focusing on bathroom modernizations and safety improvements.
