310 Junipero Serra Blvd, San Francisco, CA 94132

The two-unit residential building at 310 Junipero Serra Blvd in San Francisco's Lakeside neighborhood is a two-story flats and duplex structure built in 1941, currently owned by the Chu Oi Wong Lee Revocable Trust. The property has undergone several significant maintenance and improvement projects over the past three decades, including window replacements in 2015 (installing energy-efficient double windows), bathroom and boiler room relocations with dry rot repairs in 1992, and deck repairs in 1989.

Most recently, in early 2023, the plumbing system received attention with the replacement of the house trap and approximately 30 feet of sewer line. The building has experienced notable plumbing and sewer-related issues in recent months, particularly during late 2024, with multiple reported incidents including flooding, sewage back-up discharge from the side sewer vent, sewer odor, and general sewer problems that were all subsequently resolved through field work.

Other recent infrastructure maintenance issues in the vicinity include pavement defects, graffiti, and various street maintenance matters, all occurring between October 2024 and January 2025. While there were two fire-related incidents recorded in the past - a malfunctioning smoke detector in 2009 and an assist invalid call - neither resulted in civilian injuries. The property's planning records show an approved referral for a Cottage Food Operator permit for dehydrated Indian backpacking food in 2024, and a fire alarm system issue that was promptly resolved the same day it was reported in December 2009.
