517-519 33rd Ave, San Francisco, CA 94121

The property at 517-519 33rd Avenue in the Outer Richmond is a modern three-story multi-family residential building constructed in 2011, featuring two units and owned by Albert Ko and Marian Lam. The building underwent significant construction and safety improvements between 2005 and 2010, including the installation of a comprehensive fire sprinkler system throughout all floors and the garage, with associated underground water supply work costing approximately $18,000. The electrical system was substantially upgraded during construction, including a 200-amp service upgrade, three meters, and comprehensive wiring for lighting and receptacles.

Several safety-related issues were documented during and shortly after construction, including complaints in 2009 regarding roof safety and exterior construction not following approved plans, though these complaints were eventually resolved by January 2010. The building has experienced periodic fire safety-related incidents over the years, with the most recent being an alarm system issue in July 2024 that was promptly corrected. Historical records show two significant fire safety violations in March 2020 related to sprinkler system maintenance, though these were subsequently abated. The property has also faced some plumbing and electrical concerns, with a 2018 exit maintenance issue and a 2017 hazardous materials concern, both of which were corrected according to fire department records.

More recently, there have been multiple garbage and debris removal calls (2024) near the property, as well as a flooding incident in November 2024 that affected the property and was resolved by the Public Utilities Commission. While there have been various service requests and maintenance issues over the years, most have been promptly addressed and resolved. The building's construction history shows proper installation of safety systems, though periodic maintenance and inspection requirements have required attention. The property's recent history suggests ongoing environmental maintenance challenges, particularly in terms of waste management in the immediate vicinity.
