Initial analysis

The 8-unit apartment building at 4198 San Bruno Ave in Visitacion Valley is a 2-story multi-family residential structure built in 1963 and currently owned by John Pisani. The building has undergone several significant inspections and repairs over its history, with the most recent major activity being a sound level verification in sleeping areas completed in July 2023 to comply with Section 1103.7.6.1 of the San Francisco Fire Code. The property has experienced recurring fire safety system issues, with multiple false alarms and system malfunctions recorded between 2007 and 2011, including carbon monoxide detector activations and smoke detector activations that were determined to be due to system malfunctions rather than actual emergencies. A series of 2001 violations related to fire safety and gas utility requirements were all abated by June 2001, and similar routine inspections continued through 2011, with some violations including fire escape obstructions, fire extinguisher maintenance requirements, and gas shutoff tool requirements. The building underwent reroofing in 1993 and completed a 1986 project to bring the building into full compliance with municipal code provisions. As of 2025, there have been several reports of sidewalk issues, graffiti, and debris on the surrounding property, though these external matters do not directly reflect on the building's internal conditions or safety systems.

The building's recent history shows some attention to maintenance and compliance, with regular inspections being conducted, though many of these appear to be routine in nature. The property has experienced periodic issues with its fire safety systems, as evidenced by multiple false alarms and system malfunctions between 2007 and 2011, though all fire-related complaints were marked as "Condition Corrected." The most recent building permit from 2023 indicates ongoing compliance with sound level requirements, though one sidewalk defect reported in January 2025 remains open.

Risk rating

How 4198 San Bruno 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
9th percentile

Out of 214 buildings in this neighborhood, 195 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 49.5%
Moderate concern 28.8%
Severe concern 21.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
