Initial analysis

The 4-unit, 2-story multi-family residential building at 832 48th Avenue in San Francisco's Outer Richmond neighborhood, owned by the Chan Family Trust, has been standing since 1973 and has undergone several significant maintenance events over its history. The most recent major work was completed in 2022 when the building received a new roof at a cost of $9,800, representing the property's most up-to-date maintenance. In 2007, there was a documented water intrusion issue in Apartment #2 that caused moisture problems and prompted concerns about potential mold growth, as well as lead paint safety notifications; these violations were resolved by April 2007. Previous improvements include window replacements in 1999 (16 windows installed) and siding repairs to the lightwell area in 2007. An earlier roofing project planned for 2002 was ultimately cancelled.

The immediate vicinity of the building has experienced various urban challenges over the past two years, with multiple 311 calls logged between 2021 and 2024, primarily related to street conditions, abandoned vehicles, and encampments. Most recently, in 2024, there were three incidents involving abandoned vehicles or encampments near the property, though these were resolved through enforcement actions. Prior to that, there have been several reports of street cleaning needs, including graffiti removal and general cleaning, all of which were addressed by the appropriate authorities. While these external maintenance issues have persisted in the neighborhood, the building's documented internal maintenance history shows regular attention to major systems like roofing and windows, with the most recent being the 2022 reroofing project.

Risk rating

How 832 48Th 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

Out of 1040 buildings in this neighborhood, 926 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 units

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 51.9%
Moderate concern 14.4%
Severe concern 33.7%
