Initial analysis

The two-story multi-family residential building at 3507-3509 Mission Street in Bernal Heights, owned by the Gerardo Medina Revoc Trust, contains three units and was constructed in 1900. The property's maintenance history includes several permit records, most notably two expired permits from 1999-2000 for sheetrock replacement in the living room and bedrooms of unit 3509, and a sidewalk repair permit from 2002. Recent building inspections and maintenance issues are particularly relevant, with a building inspection complaint filed in November 2024, which has since been transferred to the Department of Building Inspection. The property has experienced recurring issues with street cleanliness and maintenance, with multiple 311 calls regarding hazardous materials (glass and paint spills), garbage, and debris between 2021 and 2024. A tree-related incident causing damage to the building was resolved in December 2023, and there are two open cases as of October 2023 - one regarding a garbage can repair and another concerning spilled liquid materials. While there was a fire-related complaint in July 2017, it was determined to have "No Merit."

The building's location has faced ongoing challenges with external maintenance and street conditions, as evidenced by the frequency of 311 calls related to the public areas surrounding the property. Historical records show limited major renovations or improvements, with the last known significant interior work dating back to 1999-2000. The property's permit and complaint history suggests a pattern of environmental maintenance issues in the immediate vicinity, though direct impacts on resident living conditions cannot be definitively assessed from the available data.

Risk rating

How 3507-3509 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.
