Initial analysis

The 4-unit, 2-story multi-family residential building at 147 12th Ave, owned by Wing Dong Fmly Tr, has been in operation since 1969 and has undergone several significant maintenance and compliance events over its history. The most recent building improvement was the unit #1 furnace replacement completed in January 2020, which followed a 1993 reroofing project. The building experienced a notable cluster of violations and complaints in May 2002 related to fire safety, including egress obstructions, other fire violations, and various plumbing and electrical issues, all of which were resolved within two weeks. A subsequent furnace installation without proper permits led to enforcement action in December 2004, though this issue was resolved by January 2005.

The property has been subject to regular inspections, including annual routine inspections in 1996 and 2008, which typically do not indicate ongoing issues. There was one documented electrical wiring/equipment problem (though details on this incident were not provided in the records). More recent activity includes a 2023 rent board inquiry regarding fee housing inventory, which was resolved with a detailed message left for the property owner. While there have been a couple of minor issues reported through 311 calls in 2019 related to parking enforcement and public works services, these were not directly related to building safety or habitability. The building's historical record shows a pattern of resolution of violations and complaints, with no active or recurring issues in recent years.

Risk rating

How 147 12Th 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
55th percentile

Out of 660 buildings in this neighborhood, 297 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.

Number of units

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

Neighborhood location

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

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 71.0%
Moderate concern 18.5%
Severe concern 10.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
