606-608 30th Ave, San Francisco, CA 94121

The two-unit residential building at 606-608 30th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1939, currently owned by Lena Ann Ngow and Tung Kalung. The property has undergone significant safety improvements in recent years, most notably the comprehensive fire sprinkler system installation in 2016-2017, which included 81 sprinklers throughout the building and a 2-inch underground fire service, along with subsequent upgrades to a sprinkler monitoring system in 2017-2018.

The building has also seen major interior improvements, including bathroom and kitchen remodels and the addition of a master bathroom, with associated plumbing upgrades completed between 2016-2017. The property has maintained active compliance with safety and infrastructure improvements, including the installation of a solar PV system in late 2017 (3.25 kW with 10 panels) and various electrical upgrades in 2016. Recent records show periodic parking enforcement actions near the property, with citations issued for driveway blocking in 2023 and 2024, though there have been relatively few significant quality-of-life issues reported through 311 calls.

A graffiti incident was reported in early 2021, and there was one unspecified noise complaint in the same year. Proposed modifications for a fourth story were previously submitted but eventually closed without violation, and there was one fire complaint in 2018 which was promptly resolved with the condition corrected notice. The building's records indicate regular maintenance and upgrades, with no major safety or habitability concerns noted in recent years.
