735 9th Ave, San Francisco, CA 94118

The two-unit residential building at 735 9th Avenue in the Inner Richmond, owned by the Rose Rosen Living Trust, has a documented history dating back to its 1913 construction. The property underwent significant modifications in 2011-2012 following a complaint about an illegal third unit, which resulted in the removal of unauthorized spaces including a full bathroom, storage rooms, and recreation room at the ground level, with associated renovations to comply with building codes, including electrical and plumbing work valued at $14,000.

A more recent improvement occurred in 2021 with the replacement of four non-street-facing windows, valued at $11,312. The building has maintained compliance with city requirements, with the illegal unit issue being officially resolved by March 2013. The property's maintenance history includes a completed reroofing project in 2006, and more recent infrastructure maintenance such as tree pruning and property upkeep in 2023.

The building has been subject to regular apartment inspections, with an active routine inspection filed in August 2017. The surrounding area has experienced various quality-of-life issues typical for urban settings, as evidenced by multiple parking enforcement actions and city services responses to street cleaning, tree maintenance, and a past encampment removal in 2021. Recent 311 calls have primarily concerned external matters such as parking violations and general maintenance of public spaces, rather than issues directly related to the building's condition or habitability.
