479 Potrero Ave, San Francisco, CA 94110

The three-unit, three-story multi-family residential building at 479 Potrero Avenue in Potrero Hill, owned by Alvin Lam, was constructed in 1987 and has undergone several significant improvements and maintenance work over the years. Most recently, in May 2024, the building completed the legalization of additional bathroom facilities in Unit A, which included comprehensive electrical, plumbing, and construction work valued at $55,000.

This followed substantial exterior work in 2022, including garage deck repairs, siding replacement, and window upgrades, demonstrating ongoing maintenance of building envelope components. The property has maintained compliance with safety standards since addressing multiple fire safety violations in 2015, which included improvements to fire extinguishers, carbon monoxide alarms, and gas utility shutoff requirements, all of which were abated by September 2015. Historical records show attention to various building systems, including a 2013 upgrade of underground gas lines for all units and multiple window replacements throughout the years.

A notable complaint in 2017 regarding construction work on the garage concrete entry was filed, though it was marked as not active. The surrounding area has experienced typical urban maintenance issues as documented in 311 calls, including occasional graffiti, sidewalk issues, and construction-related disturbances, though these have generally been resolved promptly. The building's maintenance history shows regular updates to critical systems and prompt response to violations, with no active violations or complaints on record as of October 2023.
