Initial analysis

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.

Risk rating

How 84 Onondaga Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
45th percentile

Out of 149 buildings in this neighborhood, 82 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 31.9%
Moderate concern 20.7%
Severe concern 47.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
