435 6th Ave, San Francisco, CA 94118

The two-unit, two-story residential building at 435 6th Avenue in San Francisco's Inner Richmond district is a property owned by Leong Lan Heung and was constructed in 1915 as a flats and duplex structure. The building is currently undergoing significant exterior improvements, with an issued permit from August 2024 for extensive siding work on both the rear and south walls, totaling 2,200 square feet of new composite siding at a cost of $53,000. The property has experienced recurring issues with its alarm system, with violations documented in September 2023 and August 2019, though the most recent violation has been abated.

Historical records show earlier repairs including stucco work in 1990 and reroofing in 1988, with an expired permit. The building and its immediate surroundings have been the subject of various municipal service calls in recent years, most notably including two open sidewalk defect cases (from May 2024 and November 2020). The property experienced a series of municipal interventions in 2021, when multiple instances of illegal postings were reported and resolved, along with some street cleaning and a vandalized tree incident.

Noise complaints were also recorded in early 2020. While the building has had fire code violations in 2019 and 2023, they appear to have been addressed promptly, with the most recent violation related to the alarm system being corrected. The property's maintenance history shows attention to exterior upkeep, though the recurring nature of the alarm system issues and sidewalk problems may warrant observation.
