Initial analysis

The property at 731-733 9th Avenue in San Francisco's Inner Richmond neighborhood is a two-story, three-unit multi-family residential building constructed in 1913, currently owned by Le Sandra & Tu. The building has undergone significant renovations and faced several regulatory challenges over recent years. Most notably, between 2018-2019, there were multiple substantial improvement projects including a kitchen remodel on the top floor (739 unit) with extensive dry rot repair ($32,000), replacement of rear windows ($9,000), and interior wall and ceiling work on the top floor unit ($3,000), all accompanied by the necessary electrical and plumbing permits. However, there were also several building complaints during this period regarding unpermitted work, including concerns about electrical modifications, window replacements, and construction dust management, particularly in late 2018 and 2019.

The building's history reveals some regulatory scrutiny, particularly in 2017 when multiple violations were recorded regarding safety inspections of garages, storage rooms, and common areas. These violations included requirements for carbon monoxide detectors, security features, and compliance with fire safety regulations, though records indicate these were ultimately abated. More recent history shows attention to exterior maintenance, with street space permits filed in 2020. The property has been subject to routine housing inspections over the years, with the most recent being typical for an older multi-family building in San Francisco. Recent 311 calls (2022-2025) primarily relate to street cleaning and parking enforcement issues in the vicinity, suggesting ongoing management of typical urban neighborhood concerns, though these are not directly related to the building's condition or management.

Risk rating

How 731-733 9Th 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.
