1785-1787 9th Ave, San Francisco, CA 94122

The 1785-1787 9th Avenue property is a two-unit, two-story multi-family residential building constructed in 1925, currently owned by Thein Family Trust and located in San Francisco's Inner Sunset neighborhood. The building has undergone significant recent improvements, most notably a comprehensive fire safety upgrade in 2023 that included the installation of 16 ground floor fire sprinklers, underground piping, and a new sprinkler monitoring system, with associated costs totaling approximately $24,000.

Earlier improvements included substantial interior renovations, with Unit 1787 receiving a major remodel of kitchen and bathroom facilities in 2021 (cost: $38,000), and the legalization of a previously unpermitted ground floor unit in 2018 (cost: $60,000). More recent work in 2024 involved the replacement of seven front windows with aluminum-clad wood windows. The building's history includes some past concerns regarding safety and maintenance, particularly a 2009 complaint about combustible material storage and rodent infestation that resulted in a fire safety violation, though these issues were resolved by February 2011.

All recent work has been properly permitted and completed according to building codes, with particular attention paid to fire safety systems throughout the building. The property has maintained regular upkeep through various modernization efforts, including electrical system upgrades, plumbing improvements, and general maintenance, as evidenced by the comprehensive list of permits and their respective completion statuses. While there have been several 311 calls regarding the property between 2010 to 2024, these primarily relate to external factors such as parking issues, graffiti, and sidewalk conditions, rather than building-specific problems.
