Initial analysis

The two-unit residential building at 591 7th Avenue in San Francisco's Inner Richmond district has undergone several significant changes since its construction in 1910, most notably the recent $20,000 reroofing work completed in October 2023. The building's history shows some structural maintenance, including a stair repair project in 2002 involving replacement of damaged wood with pressure-treated materials, though a 1988 effort to bring the building up to code was cancelled. The basement unit was officially removed in 1990, following a complaint in 2009 about a possible illegal unit in the garage with bathroom and kitchen facilities, which was investigated and ultimately abated in 2011.

Recent infrastructure issues include a 2021 incident with a missing PG&E electric cover in the sidewalk area that was resolved. The property has experienced recurring problems with parking violations, particularly involving vehicles on the sidewalk, with multiple enforcement actions taken between 2021 and 2024. There have also been several reports of garbage and debris issues on the street and sidewalk, with the most recent occurring in October 2024. The building's maintenance record suggests regular upkeep of critical systems, as evidenced by the recent roofing work, though the frequency of street cleaning and parking enforcement issues in the immediate vicinity indicates ongoing challenges with the surrounding public space.

Risk rating

How 591 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.
