1228-1230 4th Ave, San Francisco, CA 94122
The two-unit residential building at 1228-1230 4th Avenue in the Inner Sunset, owned by the Mogannam Family 2012 Trust, was constructed in 1907 as a two-story flats and duplex structure. The property has undergone several significant improvements in recent years, including a comprehensive renovation of Unit #1230 in 2015 that included updates to the kitchen, bathroom, dining, and living areas, along with electrical rewiring of multiple rooms, furnace replacement, and plumbing modifications including water heater relocation to the garage.
The most recent major maintenance work was completed in 2018 with a roof replacement valued at $31,800, following an earlier roofing project from 1992. The building's maintenance history shows regular upkeep of essential systems, with no recorded safety violations or major structural issues.
Recent 311 calls primarily relate to external maintenance matters, including tree maintenance and parking enforcement issues. There have been three instances of driveway blocking by a red Honda Accord in late 2023 (December 20-21), and one similar incident involving a white Honda in April 2022, all of which were resolved through official enforcement action. Additional infrastructure maintenance was required for nearby street lighting in 2021, with two lights being repaired (one for flickering and one for being burnt out), and there are several open tree-related maintenance cases from 2021-2024 that are being addressed by city services.
