523 Judah St, San Francisco, CA 94122

The property at 523 Judah Street is a three-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, built in 1915 and currently owned by Zhou Lijing. The building has undergone several significant modifications over its history, with the most recent being solar panel installation in 2013 (20 roof-mounted PV modules) and multiple roofing projects in 2002 and 2010. In 2019-2020, the building faced multiple building violations related to safety requirements, including issues with smoke alarms, fire extinguishers, and carbon monoxide detectors, though most of these violations were abated by November 2019.

The violations also included unauthorized construction work that allegedly created secondary egress issues, though the property owner filed a permit in January 2020 to remove unauthorized walls and partitions in the garage in response to these violations. The building history reveals patterns of modification and some regulatory non-compliance, particularly during the 2019-2020 period when multiple complaints were filed about unauthorized construction work, including rear wall modifications and utility installations. These complaints coincided with neighbor reports of kitchen and bathroom additions and rear construction work.

Earlier building history (2000s) shows various legitimate improvements, including deck construction, ground floor modifications, and garage door replacement. The property has also experienced recurring parking issues in recent years, with multiple reports of blocked driveways between 2023-2024. Recent environmental concerns include tree root damage to the sidewalk (2023) and periodic debris issues. The building's maintenance record shows regular upkeep, including roofing projects in 2002 and 2010, and solar panel installation in 2013, though some of these improvements have been associated with regulatory violations.
