453 21st Ave, San Francisco, CA 94121

The property at 453 21st Avenue in the Central Richmond neighborhood is a two-story, four-unit multi-family residential building constructed in 1974 and currently owned by John & Teresa Ng Lim. The building has undergone several significant improvements over the past two decades, including a complete window replacement project in 2008 ($11,250) where 23 vinyl windows were installed throughout the building, a re-roofing project in 2017 ($15,500), and the replacement of the water heater in 2020. Of particular note is the sewer/housetrap replacement completed in 2018, which is a critical infrastructure upgrade. The building has experienced two fire safety-related violation incidents, one in 2002 and another in 2011.

The 2002 incident involved issues with combustible storage and fire extinguisher maintenance, while the 2011 incident required re-inspections and confirmation of fire extinguisher placement and accessibility. All violations were resolved, with the 2002 violations being abated by June 2002 and the 2011 violations by June 2011. The property has maintained active engagement with building maintenance and compliance requirements, as evidenced by the regular issuance and completion of various permits. More recently, there have been several maintenance and service calls related to the surrounding public space, including street cleaning and waste management issues, with the most recent occurring in early 2024.

Parking enforcement has also been necessary at times in the vicinity of the property, with multiple reports of vehicles blocking driveways or parking illegally between 2019 and 2021, though these incidents were generally resolved through official response or investigation. The building's maintenance record shows regular updates and improvements to major systems, including plumbing, roofing, and windows, suggesting active property management. While there were some fire safety issues in the early 2000s, these were addressed promptly and there have been no similar violations reported in recent years. The property has remained in compliance with building codes and regulations, with all documented violations being resolved and no active complaints currently on record.
