Augrented Insights Report

The property at 143 23rd Avenue is a two-unit, two-story multi-family residential building (flats & duplex) located in San Francisco's Lake-The Presidio neighborhood. Built in 1914 and currently owned by Johnny D Jue and Oi Chin G&ngo, this building has experienced several significant maintenance and safety issues in recent years. Most notably, there is an ongoing serious concern regarding lead paint hazards, with multiple active violations filed in January 2023 related to lead abatement procedures and weather protection, prompting a director hearing date set for April 11, 2024.

Additional complaints regarding lead paint issues continued into 2024, including reports of flooding caused by lead paint debris clogging garage drains. The building has an extensive history of paint deterioration, with reported issues of peeling paint affecting neighboring properties and storm drains. The property has been subject to various infrastructure and safety concerns, including an initial roofing project completed in 1990.

Recent conditions include sidewalk tree root lifting (open case as of November 2024) and a public stairway defect (resolved in September 2024). The area around the building has experienced multiple parking enforcement issues, particularly regarding vehicles parking on the sidewalk, with several citations issued between April and June 2024. There were also incidents of flooding and waste management violations in early 2024, though these were subsequently resolved. The building’s maintenance history shows some attention to basic upkeep, as evidenced by the completed roofing work in 1990, though the persistent nature of the lead paint issues suggests ongoing challenges with property maintenance and compliance with building codes.
