1331 12th Ave, San Francisco, CA 94122

This two-unit, two-story multi-family residential building, located at 1331 12th Avenue in San Francisco's Inner Sunset neighborhood, was constructed in 1904 and is currently owned by Marc Aaron Bertone and Radwan. The property's maintenance history shows regular upkeep, with significant recent improvements including the installation of two high-efficiency gas furnaces in July 2020 and associated electrical work in August 2020.

The building has undergone several structural and safety improvements over the years, including reroofing work in 2017 (cost: $9,800), multiple repairs to rear wood stairs in 2001, and a horizontal addition completed in 1997. The building experienced a notable series of violations in January 2000, all of which were promptly addressed and abated by February 23, 2000.

These violations included issues with the rear exit door, egress obstruction, inadequate lighting, security concerns (including deadlatch locks), vermin presence, and various building maintenance matters. Since that time, the property has had three routine safety inspections (2000, 2002, and 2011) with no active violations. The recent history shows typical urban challenges in the surrounding area, as evidenced by 311 calls from 2016 (regarding homeless concerns, waste, and encampments) and vehicle-related issues in 2018 and 2023, though these are street and neighborhood matters rather than building-specific issues.
