1271 21st Ave, San Francisco, CA 94122

The two-unit residential building at 1271 21st Avenue in the Central Sunset neighborhood, owned by Lucinda F Chan, has undergone several significant infrastructure improvements since its construction in 1983. The property has received major electrical upgrades, including a 200-amp, three-meter main service upgrade completed in May 2016, and new water service installation in December 2016.

Additional maintenance work includes a water heater replacement in unit 1273 in March 2012, and a reroofing project initiated in February 2000, though that permit has since expired. Recent records from 2022 through 2024 indicate persistent parking enforcement issues in the vicinity, particularly regarding driveway blockage, with multiple citations issued between April and July 2024.

This includes seven documented cases of blocked driveways in July 2024 alone, with at least three resulting in citations, one involving a Red Prius (7DHX687). Other exterior incidents include a report of human or animal waste on the property in April 2022, which was resolved through municipal intervention. The building's permit history shows regular maintenance and upgrading of essential services since 1983, with no recorded complaints or safety violations directly related to the building's structural integrity or resident facilities.
