The property at 417-419 Cortland Avenue in Bernal Heights is a two-story, multi-family residential building with three units and a commercial space, constructed in 1890. The building has undergone several significant changes and maintenance work over the years, most notably in 2018-2017 with gas line replacements and re-piping, and in 2005 with a 200-amp underground electrical conversion.

In 2024, there were multiple fire-related violations issued for operating without permits and combustible materials, though these have been marked as abated. The building has experienced ongoing sidewalk and street-related issues in the vicinity, with several 311 calls in 2024 regarding sidewalk defects, blocked areas, and tree root damage, including an open tree maintenance issue as of February 2024. The property's maintenance history shows regular upkeep, including a roof replacement in 1992 and a significant termite damage repair in 1984.

The commercial portion of the building has undergone various modifications, including attempts to convert spaces for different uses between 1990-1993, though some permits from this period expired. While the building has generally been maintained, the recent fire code violations from 2023-2024 and various sidewalk issues suggest ongoing maintenance and compliance challenges. The property has maintained its mixed-use character throughout its history, combining residential units with commercial space, and has undergone necessary infrastructure upgrades such as gas and electrical system improvements in recent years.
