1840-1842 9th Ave, San Francisco, CA 94122

The property at 1840-1842 9th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1968 and categorized as a Flats & Duplex building, the property is currently owned by the Joanne N Mar Survivors Trust.

The building's major utility infrastructure was upgraded in June 2003 when an underground electrical service conversion was completed, transitioning to a 200-amp service with two meters. The property's documented history from 2011 to 2023 reveals recurring issues with graffiti, particularly affecting nearby poles, with the most recent instance being an open case from May 2022.

Parking and street maintenance matters have also been recorded, including a sidewalk parking violation in May 2023 that resulted in a citation, and various cleaning requests between 2019 and 2023. These maintenance issues have generally been addressed, with the most notable being a streetlight repair in August 2014 when a new 100W lamp was installed on a metal pole at the intersection of 9th Avenue. While the building itself appears to be well-maintained with only one significant infrastructure upgrade on record, the surrounding area has experienced periodic quality-of-life challenges related to street maintenance and graffiti, though most reported issues have been resolved in a timely manner.
