Initial analysis

The 4-unit multi-family residential building at 3920 Irving St in the Outer Sunset, owned by Merle F Borruso Test Tr A F, was constructed in 1959 as a two-story apartment complex. The property has a notable history of fire safety violations, with a significant cluster of issues identified during a routine inspection in February 2002, including problems with fire escape ladders, fire extinguisher maintenance, fire-proofing of ceilings, and requirements for gas utility shutoff tools and instructions. All these violations were officially abated by June 2002. Since then, there was one additional routine inspection conducted in 2009, though no violations from that inspection are currently on record.

More recently, the property has experienced numerous issues in the surrounding area, with multiple 311 calls in 2024 primarily related to garbage and debris on and around the property, including reports of abandoned furniture and loose debris. There were also two encampment-related incidents in March 2024 that required intervention, as well as reports of excessive noise in February 2024 and human or animal waste issues in August 2023 and March 2024, all of which were resolved through appropriate city services. While these recent incidents primarily relate to external conditions rather than internal building issues, they may impact the overall living environment in the area surrounding the building.

Risk rating

How 3920 Irving 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

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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

12-Month severity forecast
No violation 38.7%
Moderate concern 23.7%
Severe concern 37.6%
