Initial analysis

The three-unit multi-family residential building at 862 37th Avenue in the Outer Richmond, owned by Wing Born & Judy Quon Chea, has experienced several noteworthy incidents over the past two years. The most significant event occurred in October 2023, when there was a sewage backup involving a 4-inch sewer vent, which required attention from PUC Sewer Operations and was ultimately resolved through their Maximo Service Request system. While the property has faced recurring issues with parking violations, including multiple reports of vehicles blocking driveways and parking on sidewalks between 2022 and 2024, most of these incidents resulted in either citations being issued (in the cases of the GMC Acadia and Lexus) or officers being unable to locate the offending vehicles upon arrival.

The building's external environment has required attention to waste management, with multiple reports of garbage and debris (both loose and contained) in 2024, though most of these cases were resolved through proper channels including PW Street and Environmental Services and Recology. A minor incident involving an abandoned vehicle was reported in May 2024, but the vehicle was gone by the time authorities arrived. There has been one documented medical assistance call to the property, though this did not result in any civilian injuries. The building, constructed in 1979, is a two-story flats and duplex style structure, and while the record shows various external issues, there are no documented safety concerns within the building itself other than the one sewage incident.

Risk rating

How 862 37Th 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
30th percentile

Out of 1040 buildings in this neighborhood, 728 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 53.8%
Moderate concern 18.2%
Severe concern 28.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
