Initial analysis

The Chan Family Trust owns this two-story, four-unit multi-family residential building located at 826-828 48th Avenue in San Francisco's Outer Richmond neighborhood. Built in 1922, this apartment building has undergone several significant maintenance and inspection activities over its documented history. Most recently, a reroofing project was completed in September 2022 at a cost of $9,800, demonstrating ongoing investment in the property's maintenance. The building was also restuccoed in 1989 on its front and side portions. A routine housing inspection took place in May 2000, which was completed without any noted ongoing issues.

The property has experienced a notable pattern of encampment-related incidents in its vicinity, particularly between 2022 and 2024, with multiple cleanup requests filed through the Healthy Streets Operation Center and other agencies, though many cases were either unable to be located or deemed invalid. More recent activity at the property has been concentrated around utility service interactions, with three PUC billing-related calls in late 2024, all of which were resolved through customer communication. There were also some street cleaning matters reported in September 2024 regarding garbage and debris. Importantly, there was one documented gas leak incident (situation 412) recorded on file, though no civilian injuries were reported in connection with this event. The building's maintenance record shows regular upkeep, with no active housing violations or complaints currently on file.

Risk rating

How 826-828 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.

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 36.4%
Moderate concern 21.4%
Severe concern 42.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
