345 12th Ave, San Francisco, CA 94118

The three-story multi-family residential building at 345 12th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit structure owned by Catalaa Odette Catherine 19, constructed in 1902 as a flats and duplex building. The property's maintenance record shows two significant improvements: in 2017, five wood windows were replaced with energy-efficient wood double-hung windows, completing an upgrade to meet modern energy efficiency standards (maximum U-factor 0.32) at a cost of $7,190.

A sidewalk permit was also issued in 2007, though no associated costs were recorded. The location has experienced several documented incidents over the past several years, with the most recent being multiple reports of sidewalk parking in April 2024 and September 2019, though in both cases, responding officers were unable to validate the reported violations.

A sewage backup incident was recorded and resolved in February 2018, and the same year saw a non-offensive graffiti incident on a city receptacle that was also resolved. No significant planning code complaints or building violation notices have been filed against the property, and the building's records show no recent or recurring maintenance issues that would impact resident safety or comfort.
