419-421 Gates St, San Francisco, CA 94110

The two-unit, two-story multi-family residential building at 419-421 Gates Street in Bernal Heights was built in 1904 and is currently owned by Maurizio & Vanessa Castagna. The building has experienced several significant maintenance and regulatory issues over the years, with the most substantial period of concern occurring between 2008-2011 when multiple violations were documented, including inadequate heating, damaged walls, plumbing issues, window problems, and electrical deficiencies.

These violations were primarily addressed through a series of permits and completed work, including window retrofits, electrical panel upgrades, kitchen improvements, and heater installations. The building's maintenance history shows gradual resolution of these issues, with the last of the major violations being abated in January 2011. More recent history shows significantly fewer building-specific problems, though there have been several 311 calls regarding street maintenance issues near the property between 2021 and 2024, including reports of abandoned vehicles, garbage, and sidewalk cleaning needs.

A tree root issue causing sidewalk damage was reported in October 2022 and remains open. The property's most recent building-specific work was completed in 2010, with significant electrical upgrades being the last recorded major improvement. While the building experienced substantial habitability issues in the late 2000s, the resolution of multiple violations and completion of various permits suggest improved maintenance practices, though there have been no recorded building permits or major renovations in recent years.
