Initial analysis

The three-unit, two-story multi-family residential building at 689 47th Avenue in the Outer Richmond, owned by the Benny Wong Exemption Trust, was constructed in 1954 and has undergone some documented improvements over the years. Most notably, there was a permitted window replacement project in 2012, costing $2,000, though records show this permit was filed but not necessarily completed. An older window-related permit from 1991 shows as expired in the records. The building has undergone two routine housing inspections by Housing Inspection Services, one in 2002 and another in 2011, both of which were promptly resolved.

The property has experienced several maintenance and environmental issues in its vicinity, particularly between 2019 and 2024. Recent concerns include a reported needle-related incident (resolved) and some history of graffiti affecting nearby AT&T property between 2019-2020, though these external issues primarily relate to surrounding infrastructure rather than the building itself. There was one documented water-related incident involving a main line in 2019, which was transferred to the appropriate authorities. The building's history suggests regular maintenance and compliance with housing inspections, with no significant building-specific violations or complaints recorded in recent years.

Risk rating

How 689 47Th 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

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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 47.0%
Moderate concern 34.1%
Severe concern 18.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
