Initial analysis

The 2-unit residential building at 332-334 12th Street in San Francisco's South of Market neighborhood is a two-story flats and duplex structure built in 1909 and currently owned by the Aquino Family Trust. The property has undergone several significant modifications and faced various regulatory challenges in recent years. Most notably, in August 2022, the building received a Notice of Violation (NOV) for an unauthorized over-6-foot tall fence/gate at the rear parking area, leading to a filed permit in September 2022 to install a compliant 10-foot high wood with metal frame fence, though this permit remains in a "Filed" status. A water line replacement project was successfully completed in June 2021. The building has experienced recurring issues with unauthorized parking and related violations, as documented in multiple 311 calls and complaints throughout 2024. There have also been several fire safety system activations recorded, primarily smoke detector activations and alarm system triggers, though these incidents have not resulted in fires or injuries, with the exception of two contained cooking fires.

The property has undergone some structural improvements in the past, including reroofing work in 1993 and rebuilding of back stairs and landings in 1992, though these permits have expired. A Rear Yard Variance was approved to allow two screened off-street parking spaces within the required rear yard, along with modifications to the curb cut specifications. The building's location has generated numerous parking enforcement calls in 2024, with several resulting in citations, and there have been occasional reports of sidewalk parking and debris issues. A construction-related noise complaint was filed in September 2020, which took until April 2022 to resolve, though no ongoing construction activity was reported in a July 2024 enforcement call. While the building's systems have experienced periodic activations of fire safety equipment, these events have primarily been false alarms or unintentional activations, with no documented civilian injuries or significant fire incidents.

Risk rating

How 332-334 12Th St'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.
