Initial analysis

The property at 365 12th Street, owned by the Lorna May Choy Trust, is a 2-unit, 2-story multi-family residential building constructed in 1907, currently undergoing significant renovations to convert it into 4 dwelling units as part of a $500,000 project initiated in 2019. This extensive renovation work, which includes the installation of new decks and facade alterations, is accompanied by important safety improvements including a newly permitted fire sprinkler system installation (cost: $41,365) and the addition of new furnaces throughout the building. The building has experienced several notable structural and safety concerns, including foundation issues in 2018 that required repair (cost: $12,500), and a series of fire code violations between 2021 and 2024, with the most recent violations in 2024 relating to alarm systems, blocked exits, and multiple fire code issues, all of which were either corrected or resulted in violation notices.

The property has a documented history of maintenance and safety concerns, including an active vacant building complaint from February 2024 and a previous abandoned/neglected building complaint from 2022. Historical issues from the 1990s involved concerns about security bars on windows, which have since been resolved. The building underwent significant electrical and plumbing upgrades in late 2024, including complete rewiring of all units and underground plumbing work, indicating substantial modernization efforts. Recent 311 calls from January 2025 have primarily related to exterior issues such as graffiti and sidewalk cleaning, while previous complaints in 2018 noted concerns about construction noise affecting local residents. The building's recent history shows active management of safety violations and ongoing improvements to meet current building codes, though the presence of recent vacant building complaints suggests challenges with occupancy status.

Risk rating

How 365 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.
