130 Coso Ave, San Francisco, CA 94110

The two-unit residential building at 130 Coso Ave in Bernal Heights, owned by Sanford Joanne L & Schrank, is a two-story flats and duplex structure built in 1922. The property has undergone several significant renovations and maintenance work over the years, with the most substantial improvements occurring between 2006-2008, including comprehensive kitchen and bathroom remodels, structural work involving wall removal in both units, and deck dry rot repairs.

These renovations were accompanied by corresponding electrical upgrades, with complete wiring installations including lights, switches, and circuits, though some electrical permits did not progress beyond cancellation. The building's maintenance history shows regular upkeep, with recent roof work completed in 2011, following earlier roofing work in 1990. The building has had minimal reported issues impacting resident safety or comfort, with only one notable complaint from 1995 regarding bathroom ceiling leaks that was promptly resolved.

Recent history (2020-2024) has seen various exterior incidents including parking enforcement calls, graffiti removal, and a single sewer vent issue in 2022 that was addressed by city services. Numerous 311 calls since 2022 relate to street and sidewalk cleaning, though these appear to be primarily exterior neighborhood concerns rather than building-specific maintenance issues. The property's documented history suggests regular maintenance and significant past investments in modernization, with no major building safety violations or recurring resident comfort issues in recent years.
