4090-4092 17th St, San Francisco, CA 94114

The property at 4090-4092 17th Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1938, currently owned by the Theodore K Armstrong Living Trust. The building has undergone several significant improvements over the past two decades, with the most substantial renovations occurring between 2010-2011, including complete kitchen and bathroom remodels, electrical upgrades, plumbing improvements, and the installation of new heating systems.

A reroofing project was completed in 2011, along with compliance work following a physical inspection report, which included HVAC and electrical system updates. Recent maintenance concerns have been documented in 2024, with multiple reports of sidewalk defects, parking issues, and garbage debris in the vicinity. The building has a documented history of various system malfunctions, including multiple false alarms and elevator service calls, though fortunately, none of these incidents resulted in civilian injuries.

The property underwent a two-unit residential condo conversion process, which is noted as "Closed - Approved" in the planning records. While there have been numerous 311 calls regarding the surrounding area, particularly in late 2024, these primarily relate to street maintenance and public infrastructure rather than building-specific issues. The most recent documented permit activity was a street space permit issued in 2016, though this was a minimal cost item.
