431-433 Delano Ave, San Francisco, CA 94112

This two-unit, two-story multi-family residential building located at 431-433 Delano Ave in Mission Terrace, owned by Albert & June Ottoboni, was constructed in 1959. The building's maintenance record shows regular attention to window maintenance, with permits issued in 2007 for the installation of six replacement windows, valued at $3,500.

More concerning is the building's recent history of fire safety issues, with multiple violations documented between 2014 and 2024, including open violations as of September 2024 related to fire extinguishers, emergency lighting, and sprinkler maintenance at a neighboring address (241 Oneida Ave). The property has experienced several fire-related incidents, though all were due to system malfunctions or equipment issues with no civilian injuries recorded.

Between October 2024 and January 2025, there has been a notable pattern of garbage and debris issues in the vicinity, with multiple reports of abandoned furniture, hazardous waste, and overflowing city garbage cans, though most of these cases were promptly resolved. Additionally, there were three documented instances of sidewalk parking violations in November 2024, resulting in citations. While the building has maintained compliance with window upgrades and addressed various fire code violations over the years, the recurring nature of fire safety concerns and recent issues with waste management in the surrounding area may require attention.
