Initial analysis

4531 Mission Street is a two-story, multi-family residential building with commercial space, located in San Francisco's Excelsior neighborhood. The property, built in 1900 and containing two units, is notable for its recent structural concerns, particularly an active violation from June 2023 regarding a collapsed retaining wall at the rear property line, which has been classified as an unsafe condition. This issue appears to be connected to a similar complaint filed by a neighboring property owner, highlighting potential stability and safety concerns. The building has been facing persistent challenges with its commercial space, evidenced by multiple violations of the Vacant or Abandoned Commercial StoreFront Ordinance, with active violations from 2023 resulting in monthly monitoring fees. These violations have followed a pattern; for instance, a 2019 violation for vacant storefront status was previously addressed but appears to have recurred.

The property has a documented history of maintenance activities, including a complete reroofing project completed in 1997. Recent years have seen increased attention to the building's condition, with complaints about mold (2020) and reports of vacant commercial space (2019). The building has experienced multiple instances of graffiti and exterior maintenance issues in 2024, as evidenced by numerous 311 calls regarding offensive graffiti and property damage, though many of these were resolved promptly. A possible illegal use of the commercial space was previously investigated but has since been closed as abated. While the building's residential units themselves have had fewer documented issues, the combination of structural concerns, commercial space violations, and recent exterior maintenance challenges suggests that the property requires ongoing attention to maintain both safety and compliance standards.

Risk rating

How 4531 Mission 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.
