171-173 9th Ave, San Francisco, CA 94118

The two-unit residential building at 171-173 9th Avenue, owned by the Chung Amy Lee Trust A, is a two-story flats and duplex structure built in 1913 in San Francisco's Lake-Presidio neighborhood. The building's maintenance history shows regular upkeep, with documented improvements including the installation of four new vinyl windows in 1999 and stucco replacement work in 1989, both of which were completed successfully.

More recently, in 2015 and 2016, the property required street space permits, though the minimal associated costs of $1 for each permit suggest these were likely routine administrative matters. The building's location has experienced some quality-of-life challenges in recent years, with two incidents reported in November 2022 involving graffiti (described as offensive) and a defaced parking sign, both of which were resolved by city services.

While there were two reports of abandoned vehicles in September and October 2010 near the property, both incidents were resolved when the vehicles were found to be gone upon inspection. The relatively limited number of complaints and the significant age of the building's most recent permits (dated back to 2015-2016) could suggest either fewer recent maintenance needs or possible changes in permit usage frequency over time.
