2070 Bancroft Ave, San Francisco, CA 94124

The two-unit residential building at 2070 Bancroft Avenue, located in Silver Terrace, is a single-story structure built in 1948 and currently owned by Yang Liangfa. The property has undergone some significant electrical upgrades in recent years, including a 200-amp service upgrade in January 2020, though an earlier solar installation project from 2014 (featuring 22 roof-mounted solar PV modules) appears to have expired without completion.

The building's recent maintenance history has notable concerning elements, particularly a sewage backup incident in October 2023 that required intervention from PUC Sewer Operations. The property has generated multiple 311 calls in the past year (2023-2024), with recurring issues related to street cleaning, including several cases of abandoned mattresses and furniture, though these were all resolved through appropriate city services. There have also been two documented cases of vehicles blocking driveways, resulting in citations in February 2024 and November 2019.

The surrounding area has experienced various maintenance and compliance issues, as evidenced by multiple street cleaning requests ranging from hazardous materials (oil/paint) in May 2020 to general cleaning needs in February 2022. Two tenant buyouts in the vicinity suggest some level of residential turnover in the area, with significant compensation amounts of $80,000 for three tenants in January 2023, though these occurred at different addresses (670 Thornton Avenue and 665 Thornton Avenue) and are not directly related to the current building. The property's documented history shows regular interactions with municipal services for both routine maintenance and emergency responses, with all reported issues being resolved through appropriate channels, though the serial nature of some street cleaning requests and the recent sewage incident may indicate ongoing environmental and maintenance challenges.
