Initial analysis

The property at 497 15th Avenue in the Central Richmond neighborhood is a two-story, two-unit multi-family residential building constructed in 1920, currently owned by Thomas Gee and Sally Lee Yuen. The building's maintenance history shows attention to structural integrity, with a significant dryrot repair project undertaken in May 2011 at a cost of $6,000, involving wood replacement and brick work, while a minor street space permit was also issued in October 2011.

The most recent incidents in 2023 have primarily involved street and sidewalk maintenance issues, with the most significant being an ongoing situation with tree roots damaging the sidewalk (reported November 2023). There have been multiple reports of hazardous materials (two glass-related incidents in June 2023), illegal parking violations, and instances of street cleaning needs, including a general cleaning case (September 2023) and a graffiti incident (February 2023). The property appears to be experiencing ongoing challenges with parking enforcement and sidewalk maintenance in its immediate vicinity, though these issues primarily relate to public space rather than the building itself. The documented history suggests regular maintenance of the building structure was performed when necessary, with no recorded major safety incidents or violations related to the property itself.

Risk rating

How 497 15Th 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.
