Initial analysis

The three-unit multi-family residential building at 997-999 Tennessee Street, owned by Paul Zingaro and Channon Cons, has a significant history of building maintenance and safety concerns dating back to its construction in 1900. The most recent major exterior work involved the replacement of two garage doors in 2021, while earlier maintenance included front parapet shingle repairs in 2004 and a foundation replacement along the left side in 2002 (though this permit expired). More critically, the building has experienced numerous fire safety issues in recent years, with multiple fire code violations documented between 2018 and 2024, including two violations issued in September 2024 regarding ERRCS permits. The fire alarm system has shown persistent problems, with violations and false alarms recorded between 2009 and 2024, though most were resolved promptly.

The property has faced ongoing challenges with its immediate surroundings, as evidenced by multiple 311 calls in 2024 regarding sidewalk defects, garbage and debris, and homeless encampments near the property. There have been two documented instances of collapsed sidewalk issues in late 2024, and several garbage-related complaints, including a missed collection in December 2024. While the building's fire safety systems have required frequent attention, it is worth noting that no civilian injuries have been reported in any of the documented fire incidents or alarms. The property's recent history shows a pattern of addressing maintenance issues as they arise, though some structural concerns from previous decades remain on record.

Risk rating

How 997-999 Tennessee St'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
80th percentile

Out of 74 buildings in this neighborhood, 15 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.

Neighborhood location

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

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

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 51.5%
Moderate concern 34.0%
Severe concern 14.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
