248 Corbett Ave, San Francisco, CA 94114

The property at 248 Corbett Avenue is a two-story, four-unit multi-family residential building located in Corona Heights, constructed in 1904 and currently owned by the Malchow Martin Trust. The building has undergone several significant improvements over the years, including a complete reroofing in 2008 costing $11,900, and critical infrastructure upgrades in 2004 such as the replacement of a 6-foot front property line retaining wall ($15,000) and conversion from overhead to underground electrical service.

Security enhancements were made in 2003 following a violation for inadequate entry door glazing, which was promptly addressed within four months. Regular routine housing inspections were conducted in 2002, 2010, and 2017, with the most recent inspection showing no active violations. The building's recent history shows minimal internal issues, with only one minor incident recorded: a carbon monoxide detector activation that was investigated and found to have no CO present.

However, there have been numerous reports in the immediate vicinity of the building regarding external conditions, including recurring issues with sidewalk blocking, garbage accumulation, and street cleaning needs between 2020 and 2025. Notably, there are documented problems with sidewalk maintenance, including a lifted section near a utility vault in early 2021 that was inspected and reported. While the building's internal systems and structure appear well-maintained based on historical permit records and routine inspections, the surrounding area has experienced ongoing challenges with public space maintenance and enforcement issues, particularly regarding parking compliance and sidewalk accessibility.
