Initial analysis

The 4-unit, 2-story multi-family residential building at 1238 12th Avenue in San Francisco's Inner Sunset neighborhood, owned by Fong Wing Fung & Yuen Kuen, has been in operation since its construction in 1974. The building's documented history shows a relatively stable pattern of maintenance and incident responses, with no active building complaints on file since a routine housing inspection in 2001. However, there have been recurring issues with sewage backups, with three documented incidents in 2015 (March and October) and one in September 2017, all of which were resolved through PUC Sewer Operations. Water quality concerns were noted in May 2016, and a pavement defect was reported in December 2019.

The most recent issues primarily relate to parking concerns, with two driveway blocking incidents reported in 2025 and 2023, though enforcement officers were unable to locate the offending vehicles in both cases. A construction noise complaint was recorded in May 2022, and there have been occasional reports of street cleaning needs and abandoned vehicles in the vicinity, including an abandoned Subaru in April 2013. While the building has experienced periodic infrastructure challenges, particularly with sewer systems, all reported issues have been addressed and resolved according to available records. The last significant building-related incident was a construction noise complaint more than a year ago, and all historical sewage issues have been resolved through proper channels.

Risk rating

How 1238 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

Out of 1493 buildings in this neighborhood, 1165 are predicted to be safer.
