Initial analysis

The two-unit residential building at 643 7th Avenue in San Francisco's Inner Richmond District is a two-story flats and duplex structure built in 1911, currently owned by Eleanor Y. Leung. The building underwent a permitted renovation in 1998 to add a bathroom and bedroom to the lower level, which was completed successfully.

The property has experienced several maintenance issues over the years, particularly with the public sidewalk area, which has been documented in multiple complaints between 2014-2016. These included multiple reports of lifted sidewalk defects in February 2014, with at least four separate incidents being reported and documented as damaged, though most were resolved satisfactorily. There were also two instances of sidewalk parking violations reported in 2022, and two more recent complaints about sidewalk parking in early 2025, though enforcement officers were unable to locate the vehicles in each case. Additional minor incidents included a 2017 report of graffiti, which was determined to be a non-valid street lighting issue, and a 2021 case involving illegal multiple postings that was resolved by the Department of Public Works. While the building itself appears to be structurally sound with no recent major complaints or violations on record, the surrounding sidewalk area has experienced recurring maintenance issues that were primarily addressed through official channels.

Risk rating

How 643 7Th 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.
