431 Burnett Ave, San Francisco, CA 94131

This two-unit multi-family residential building, located at 431 Burnett Avenue in Twin Peaks, was constructed in 1975 and is currently owned by the Alan Chew Revocable Trust. The property has undergone several significant improvements over the years, with the most recent major work being a reroofing project in 2017 valued at $12,700. Previous renovations include a substantial siding replacement project in 2016 ($4,500) involving the installation of cement lap siding at the rear of the building, and a comprehensive kitchen remodel on the second floor in 2010 ($9,500) that incorporated energy-efficient lighting and modern appliances.

The building has experienced some maintenance issues in the past, including termite repairs in 1993, exterior pest control work in 1990, and an important plumbing dispute in 2009-2010 concerning a disputed sewage line that was reportedly resolved. Recent infrastructure work has included various electrical and plumbing upgrades, most notably during the 2008-2010 renovation phases. The property has had several environmental and maintenance issues reported through the 311 system in recent years, with the most pressing current concern being an open case from January 2025 regarding an overgrown tree blocking street lights.

Other recent incidents include a January 2023 flooding issue on the street, and various street maintenance matters such as loose garbage removal and illegal parking. The building's record shows consistent attention to maintenance and improvements, particularly in the late 2000s through 2017, with fewer major works recorded in recent years. While there have been some neighborhood infrastructure issues reported through 311 services, these generally pertain to public street conditions rather than the building itself. The property's planning records indicate compliance with local regulations, including a CEQA clearance for construction of the two duplex units with required front setbacks.
