Initial analysis

The two-unit multi-family residential building at 237 12th Avenue in San Francisco's Inner Richmond neighborhood is a one-story flats and duplex structure built in 1900, currently owned by Fai Fong & Betty Puiwan Cha. The property's maintenance record shows two significant building permits: a street space permit issued in April 2018 for a nominal cost, and a complete reroofing project from April 2011 that cost $16,500.

The building's recent maintenance and incident history from 2020 to 2024 reveals ongoing urban challenges typical of the neighborhood, though none directly related to the building's structural integrity or safety. The most recent incident was reported in February 2024, involving general street cleaning for loose garbage, and prior incidents include various municipal service calls such as illegal postings (2022), an overflowed city garbage can (2022), a burnt-out street light (2021), and abandoned cart pickup (2021). A sequence of sanitation-related issues is evident in 2020, with multiple reports of loose garbage, graffiti on a signal box, and two instances of illegal parking requiring police intervention. While these incidents reflect some neighborhood maintenance issues, it's important to note that all reported cases were resolved through appropriate city services, with no recorded impact on the building's habitability or safety systems.

Risk rating

How 237 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
49th percentile

Out of 1723 buildings in this neighborhood, 879 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 76.7%
Moderate concern 18.5%
Severe concern 4.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
