3340 San Bruno Ave, San Francisco, CA 94134

The property at 3340 San Bruno Avenue is a six-unit, multi-family residential building constructed in 1914, currently owned by Liang Zhichao. The building has experienced several significant maintenance and compliance issues in recent years, with the most concerning being an active complaint from May 2023 regarding a leaking ceiling that resulted in ceiling collapse onto a bed. Other notable recent issues include a broken house trap in 2021, water damage repairs in 2014, and multiple building code violations in 2018 relating to security, plumbing, and weatherproofing concerns.

The property has undergone several major improvements, including a comprehensive plumbing upgrade in 2014 that replaced all iron pipes with copper, electrical work, and a kitchen/bathroom remodel in Unit 5. There have been multiple instances of unauthorized construction, most notably a disputed elevated deck/structure in 2017 that generated several complaints. The building's emergency systems were notably upgraded between 2001 and 2018, with violations relating to fire escape ladders, gas meter instructions, smoke detectors, and security locks being addressed.

Recent infrastructure concerns in the surrounding area include multiple sewer-related incidents and water main issues reported in 2024. The property has been the subject of various planning proposals, including past attempts to demolish the existing structure and construct a new building with additional units, though these have generally been disapproved or put on hold. The building's maintenance history shows a pattern of responding to both resident complaints and regulatory enforcement actions, with various permits filed to address building violations, repair work, and improvements. While many historical violations have been resolved, the continuing pattern of maintenance issues, particularly in the past decade, suggests ongoing challenges with building upkeep and infrastructure stability.
