Initial analysis

The property at 419-423 Clement Street in San Francisco's Inner Richmond neighborhood is a two-story, multi-family residential building constructed in 1900 that contains two units, plus retail space, owned by Timothy Lee Tit Wan. The building has undergone several significant modifications over the years, including completed kitchen and bathroom renovations in 2010, and more recently, the removal of an exterior wood ladder in 2019 to address safety violations. The property has experienced three notable safety-related incidents between 2017 and 2019: a hazardous exterior wooden ladder situation (2017), a dislodged decorative corbel posing a street hazard (2018), and a vacant commercial storefront violation (2019) - all of which were eventually abated.

Additional historical improvements include the conversion of retail space to a beauty store in 1992, division of storage areas in 1995, and various exterior modifications in the 1980s including an awning installation and horizontal addition. The most recent records from 2021-2023 show routine urban challenges, including maintenance issues such as graffiti, damaged parking meters, and sidewalk obstruction complaints. Two minor fire-related incidents have been recorded, with no civilian injuries reported. The building's permit and violation history indicates active management response to compliance issues, particularly focusing on safety-related concerns, though some historical permits (e.g., a 2017 bathroom remodel) were cancelled before completion.

Risk rating

How 419-423 Clement 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.
