84 Onondaga Ave, San Francisco, CA 94112

The two-story, five-unit apartment building at 84 Onondaga Avenue in Mission Terrace, owned by Salvatore Carmine Timpano, was constructed in 1955 and has undergone several significant maintenance and upgrade projects over the years. Most recently, in 2017, the building received window upgrades with the replacement of eight windows (four street-facing and four rear) at a cost of $6,000.

In 2013, all four furnaces serving units 1-4 were replaced. The building has experienced recurring maintenance issues, particularly with its sewer system, as evidenced by multiple service calls between 2018 and 2024 regarding sewage backup problems, including a recent incident in September 2024 involving discharge from a side sewer vent. The building's history shows some concerning patterns, including multiple fire safety violations in 2001 and 2004 (which were subsequently abated) related to combustible storage, egress obstructions, and fire extinguisher requirements.

A routine inspection in 2011 noted common area maintenance issues including cracking hallway linoleum, which raised potential asbestos concerns. Ongoing maintenance appears to be a consistent focus, as demonstrated by several routine housing inspections and the timely addressing of various building code requirements over the years. The property has also experienced some exterior access issues, with several parking enforcement calls related to driveway blocking and sidewalk parking violations between 2018 and 2024.
